Drug Used to Treat Rheumatoid Arthritis May Also Help Prevent It

A clinical trial  showed that the  drug abatacept (Orencia) – which is already used to treat diagnosed rheumatoid arthritis – also can prevent people from progressing to the painful inflammatory disease.

Abatacept eases symptoms and prevents joint damage in rheumatoid arthritis patients by dampening the immune system, researchers said.

About 1.3 million Americans live with rheumatoid arthritis, which occurs when the body’s immune system starts attacking tissues in the joints, causing inflammation, pain and swelling.

Day’s clinical trial showed that abatacept also is effective in preventing the onset of rheumatoid arthritis.

About 6% of patients treated with abatacept developed arthritis compared to 29% given a placebo following a year of treatment, according to clinical trial results published Feb. 13 in The Lancet.

“This is the largest rheumatoid arthritis prevention trial to date and the first to show that a therapy licensed for use in treating established rheumatoid arthritis is also effective in preventing the onset of disease in people at risk,” researcher Andrew Cope, head of the King’s College London Center for Rheumatic Diseases, said in a news release.

“These initial results could be good news for people at risk of arthritis, as we show that the drug not only prevents disease onset during the treatment phase but can also ease symptoms such as pain and fatigue,” he continued.

For the clinical trial, researchers recruited 213 patients older than 18 at high risk of rheumatoid arthritis. They all had early symptoms like joint pain, but no swelling that would lead to a formal diagnosis.

Rheumatoid arthritis most often begins in middle age, but also can affect much younger adults, researchers said.

“Enrolling in the trial was a no-brainer; it was a ray of hope at a dark time,” Day said.

Half of the participants were treated with abatacept and the other half with a placebo every week for a year. The drug is given by weekly injections at home or in a hospital via an IV drip.

After a year of treatment, the drug was stopped and patients were monitored to see how many would develop rheumatoid arthritis.

After the full two years, 25% of abatacept patients had progressed to rheumatoid arthritis compared with 37% of those on a placebo.

“The results clearly show that during the treatment period almost all individuals receiving the biologic drug showed no symptoms or signs of RA compared with the control population,” Ravinder Maini, an emeritus professor of rheumatology at Imperial College London who was not involved in the research, said of the clinical trial.

AbbVie Announces New Drug Application Accepted for Priority Review by FDA for Upadacitinib for Treatment of Moderate to Severe Rheumatoid Arthritis

  

In continuation of my update on upadacitinib 

AbbVie (NYSE: ABBV), a research-based global biopharmaceutical company, has announced that the U.S. Food and Drug Administration (FDA) has accepted for priority review its New Drug Application (NDA) for upadacitinib for the treatment of adult patients with moderate to severe rheumatoid arthritis. Upadacitinib is an investigational once-daily oral JAK1-selective inhibitor being studied for multiple immune-mediated diseases.1-13 AbbVie anticipates a regulatory decision in Q3 2019.

The NDA is supported by data from the global upadacitinib SELECT Phase 3 rheumatoid arthritis program evaluating more than 4,000 patients with moderate to severe rheumatoid arthritis across five of six Phase 3 studies.3-7 In all SELECT Phase 3 studies, upadacitinib met all primary and ranked secondary endpoints. The most frequent serious adverse events were infections.3-7 Top-line results from these clinical studies were previously announced.

Upadacitinib is also under review by the European Medicines Agency for the treatment of adult patients with moderate to severe rheumatoid arthritis.

About the SELECT Study Program 

The robust SELECT Phase 3 rheumatoid arthritis program evaluates more than 4,900 patients with moderate to severe rheumatoid arthritis in six studies, five of which support regulatory submission for upadacitinib. The studies include assessments of efficacy, safety and tolerability across a broad range of rheumatoid arthritis patients. Key measures of efficacy evaluated include ACR responses, Disease Activity Score (DAS28-CRP) and inhibition of radiographic progression. More information on these trials can be found at www.clinicaltrials.gov (NCT02706847, NCT03086343, NCT02629159, NCT02706873, NCT02706951, NCT02675426).

About Upadacitinib

Discovered and developed by AbbVie, upadacitinib is an investigational oral, small molecule JAK1-selective inhibitor being studied for moderate to severe rheumatoid arthritis and other immune-mediated diseases.1-2 The FDA granted priority review for AbbVie's NDA for moderate to severe rheumatoid arthritis in Q1 2019. Phase 3 trials of upadacitinib in atopic dermatitis, psoriatic arthritis, Crohn's disease, and ulcerative colitis are ongoing and it is also being investigated to treat ankylosing spondylitis.9-13Upadacitinib is not approved and its safety and efficacy have not been evaluated by regulatory authorities.

Chemical compound shows promise in treating rheumatoid arthritis

Montana State University researchers and their collaborators have published their findings about a chemical compound that shows potential for treating rheumatoid arthritis.

The paper ran in the June issue of the Journal of Pharmacology and Experimental Therapeutics (JPET), and one of its illustrations is featured on the cover. JPET
is a leading scientific journal that covers all aspects of pharmacology, a field that investigates the effects of drugs on biological systems and vice versa.

"This journal is one of the top journals that reports new types of therapeutics that are being developed," said Mark Quinn, senior author on the paper and a professor in MSU's Department of Microbiology and Immunology. The department is part of the College of Agriculture and the
College of Letters and Science.

Rheumatoid arthritis is a chronic autoimmune disorder that affects an estimated 1.3 million people in the world, Quinn said. Characterized by stiff, swollen joints, it's a progressive disease that occurs when the body's immune system attacks its own cells. Inflammation in the lining of the joints leads to loss of bone and cartilage. People who have rheumatoid arthritis lose mobility and joint function without adequate treatment.

New kinds of drugs have been developed for treating the disease, Quinn said. Called biological drugs, or "biologics," they are made from genetically engineered proteins or antibodies that act on substances in the immune system. When used to treat rheumatoid arthritis, they interrupt signals that fuel the inflammatory process. Two such drugs are ENBREL and HUMIRA.

Biologics can be expensive, however, and some people don't respond to
them, Quinn said. Some people respond at first, but not forever.

"There is a real need to develop new kinds of drugs that are different," Quinn said. "They could be combined with other available drugs or replace drugs that aren't working for patients."

Researchers in his laboratory and elsewhere identified a new chemical compound, called IQ-1S, in a previous study, Quinn said. Then they conducted a new study to understand how the   small-molecule  compound
works against rheumatoid arthritis. They explained their findings in the JPET paper.

FDA Approves Rinvoq (upadacitinib), an Oral JAK Inhibitor for the Treatment of Moderate to Severe Rheumatoid Arthritis

In continuation of my update on Rinvoq (upadacitinib)

AbbVie (NYSE: ABBV), a research-based global biopharmaceutical company, today announced that the U.S. Food and Drug Administration (FDA) has approved Rinvoq (upadacitinib), a 15 mg, once-daily oral Janus kinase (JAK) inhibitor, for the treatment of adults with moderately to severely active rheumatoid arthritis (RA) who have had an inadequate response or intolerance to methotrexate (MTX-IR).1 Rinvoq is expected to be available in the U.S. in late August 2019.

The FDA approval of Rinvoq is supported by data from the SELECT program, one of the largest registrational Phase 3 programs in RA with approximately 4,400 patients evaluated across all treatment arms in five studies.2-6 The studies include assessments of efficacy, safety and tolerability across a variety of RA patients, including those who failed or were intolerant to biologic disease-modifying anti-rheumatic drugs and who were naïve or inadequate responders to methotrexate. Rinvoq is not indicated for methotrexate-naïve patients.

"Despite the availability of multiple treatment options with varying mechanisms of action, many patients still do not achieve clinical remission or low disease activity—the primary treatment goals for rheumatoid arthritis," said Roy M. Fleischmann, M.D., primary investigator for SELECT-COMPARE and clinical professor at the University of Texas Southwestern Medical Center at Dallas. "With this FDA approval, Rinvoq has the potential to help additional people living with RA achieve remission who have not yet reached this goal."

Across the SELECT Phase 3 studies, Rinvoq met all primary and ranked secondary endpoints. The primary endpoints include:

• In SELECT-EARLY, 52 percent of MTX-naïve patients treated with Rinvoq 15 mg achieved ACR50 vs 28 percent treated with MTX at week 121
• In SELECT-MONOTHERAPY, 68 percent of MTX-IR patients treated with Rinvoq 15 mg achieved ACR20 vs 41 percent treated with continued MTX at week 141
• In SELECT-COMPARE, 71 percent of MTX-IR patients treated with Rinvoq 15 mg plus MTX achieved ACR20 vs 36 percent treated with placebo plus MTX at week 121
• In SELECT-NEXT, 64 percent of csDMARD-IR patients treated with Rinvoq 15 mg plus csDMARDs achieved ACR20 vs 36 percent treated with placebo plus csDMARDs at week 121
• In SELECT-BEYOND, 65 percent of biologic-IR patients treated with Rinvoq 15 mg plus csDMARDs achieved ACR20 vs 28 percent treated with placebo plus csDMARDs at week 121

"The discovery and development of Rinvoq is indicative of AbbVie's long-standing commitment to advancing the science for people living with immune-mediated conditions," said Michael Severino, M.D., vice chairman and president, AbbVie. "Today's FDA approval marks an important milestone in our pursuit to deliver innovative medicines that advance care for people living with rheumatoid arthritis."

Clinical Remission

Patients taking Rinvoq achieved clinical remission, a state characterized by almost no disease activity and symptoms, even without methotrexate.2-3,6 Approximately 30 percent of patients treated with Rinvoq achieved clinical remission (as assessed by DAS28-CRP<2.6) at week 12 in SELECT-COMPARE and week 14 in SELECT-MONOTHERAPY compared to six percent with placebo plus methotrexate and eight percent with methotrexate, respectively.1 In SELECT-EARLY, 36 percent of patients treated with Rinvoq achieved clinical remission (as assessed by DAS28-CRP<2.6) at week 12 compared to 14 percent with methotrexate.1 

Durable remission rates were observed up to week 26. Forty-eight percent of patients treated with Rinvoq alone in SELECT-EARLY and 41 percent of patients treated with Rinvoq plus methotrexate in SELECT-COMPARE achieved clinical remission at weeks 24 and 26, compared to nine percent with placebo plus methotrexate and 18 percent with methotrexate, respectively.1 Analysis at weeks 24 and 26 were not controlled for multiple comparisons.3,10

Radiographic Inhibition

Rinvoq significantly inhibited radiographic progression as measured by the change in modified total Sharp score (mTSS) from baseline compared to methotrexate in SELECT-EARLY (0.14 vs 0.67) and Rinvoq plus methotrexate compared to placebo plus methotrexate in SELECT-COMPARE (0.15 vs 0.78) through weeks 24 and 26, respectively.1 

Safety

The most common side effects associated with Rinvoq include upper respiratory tract infections (common cold, sinus infections), nausea, cough and pyrexia.1 Patients treated with Rinvoq are at increased risk for developing serious infections that may lead to hospitalization or death. These infections include tuberculosis (TB), invasive fungal, bacterial, viral, and other infections due to opportunistic pathogens. Most patients who developed these infections were taking concomitant immunosuppressants such as methotrexate or corticosteroids.1 Lymphoma and other malignancies have been observed in Rinvoq-treated patients.1 Thrombosis, including deep vein thrombosis, pulmonary embolism, and arterial thrombosis, have occurred in patients treated with JAK inhibitors used to treat inflammatory conditions.1 Patients treated with RINVOQ also may be at risk for other serious adverse reactions, including gastrointestinal perforations, neutropenia, lymphopenia, anemia, lipid elevations, liver enzyme elevations, and embryo-fetal toxicity.1 

Ease of Use and Access

Designed to help accommodate the physical limitations of people living with RA, the packaging for Rinvoq includes a bottle cap with a wide, easy-to-grip texture and an embedded tool that punctures the foil liner to simplify medication access. This packaging design was awarded the Arthritis Foundation Ease of Use Commendation.

"Rheumatoid arthritis can have a debilitating impact on the lives of those with the chronic disease, including making it difficult to perform everyday tasks," said Cindy McDaniel, senior vice president, consumer health, Arthritis Foundation. "The Arthritis Foundation is committed to recognizing innovation that can help patients living with rheumatoid arthritis and we are proud to recognize AbbVie with our Ease of Use Commendation for the packaging design of Rinvoq."

AbbVie continues to work closely with key stakeholders to support patient access to Rinvoq, including offering a patient support program and a co-pay card that may reduce out-of-pocket costs to $5 per month for eligible, commercially-insured patients. For those with limited or no health insurance, AbbVie offers myAbbVie Assist, a patient assistance program that provides Rinvoq to qualifying patients.

FDA Approves RediTrex (methotrexate) for Rheumatoid Arthritis, Juvenile Idiopathic Arthritis, and Psoriasis

In continuation of my update on methotrexate

Cumberland Pharmaceuticals Inc. (NASDAQ: CPIX), a specialty pharmaceutical company, today announced that it has received approval from the U.S. Food and Drug Administration (FDA) for RediTrex, its new line of methotrexate products.

RediTrex (methotrexate) injection is designed for the treatment of adult and pediatric patients with rheumatoid arthritis, as well as adults with psoriasis. The approval of the product came after a number of communications with the FDA and several amendments to the New Drug Application we submitted to the FDA in late 2018.

Methotrexate is approved in the U.S. as both an oral and injectable treatment. While oral formulations are widely available, injectable methotrexate has been shown to result in increased efficacy, greater continuation rates and less discomfort for patients. Cumberland's methotrexate products will provide enhancements and patient benefits over conventional injectable methotrexate products currently available in the U.S.

Cumberland has acquired exclusive U.S. commercial rights to Nordic Group B.V.'s (Nordic) injectable methotrexate line of products. Nordic is a privately-owned European pharmaceutical company with a presence in 17 countries. The company focuses on the development and commercialization of niche hospital and orphan products, aiming to address unmet medical needs. Nordic's methotrexate products are established market leaders in multiple European countries.

"We are delighted by the FDA approval of RediTrex for the United States," said A.J. Kazimi, Chief Executive Officer of Cumberland Pharmaceuticals. "We are looking forward to bringing this important product to the patients seeking an easy-to-use methotrexate injectable."

Cumberland will launch two injectable methotrexate product lines within the U.S., with both product offerings intended for the treatment of active rheumatoid arthritis, juvenile idiopathic arthritis and severe psoriasis.

The injectable U.S. methotrexate market totaled over 670,000 prescriptions last year, with approximately $80 million in overall sales. This methotrexate market has grown at a rate of 72 percent over the previous three years. Cumberland's goal is to achieve a significant share of the injectable methotrexate market over time through the introduction of RediTrex.

Pfizer Announces FDA Approval of Xeljanz (tofacitinib) and Xeljanz XR for the Treatment of Active Psoriatic Arthritis

In continuation of my update on tofacitinib 

Pfizer Inc.  announced that the United States Food and Drug Administration (FDA) has approved Xeljanz 5 mg twice daily (BID) and Xeljanz XR (tofacitinib) extended release 11 mg once daily (QD) for the treatment of adult patients with active psoriatic arthritis (PsA) who have had an inadequate response or intolerance to methotrexate or other disease-modifying antirheumatic drugs (DMARDs). Xeljanz/Xeljanz XR is the first and only Janus kinase (JAK) inhibitor approved by the FDA for both moderate to severe rheumatoid arthritis (RA) and active PsA.

“Psoriatic arthritis is a complex and progressive disease with an unpredictable course,” said Angela Hwang, Global President, Inflammation and Immunology, Pfizer. “The approval of Xeljanz is an important step forward for patients seeking new treatments and is a testament to Pfizer’s unwavering commitment to advancing patient care.”

The recommended dose of Xeljanz/Xeljanz XR is in combination with nonbiologic DMARDs, and use in combination with biologic DMARDs or with potent immunosuppressants such as azathioprine and cyclosporine is not recommended.

The FDA approval of Xeljanz for the treatment of adult patients with active PsA was based on data from the Phase 3 Oral Psoriatic Arthritis Trial (OPAL) clinical development program, which consisted of two pivotal studies, OPAL Broaden and OPAL Beyond, as well as available data from an ongoing long-term extension trial, OPAL Balance. The findings from OPAL Broaden and OPAL Beyond were published in October 2017 in the New England Journal of Medicine.

Both pivotal studies met their two primary efficacy endpoints, demonstrating statistically significant improvements in American College of Rheumatology 20 (ACR20) response and change from baseline in the Health Assessment Questionnaire–Disability Index (HAQ-DI) score at three months in patients receiving Xeljanz 5 mg BID treatment in combination with a nonbiologic DMARD, compared to those treated with placebo. In OPAL Broaden, 50% of patients taking Xeljanz 5 mg BID achieved an ACR20 response, compared to 33% of patients taking placebo (p≤0.05), at three months. In OPAL Beyond, 50% of patients achieved an ACR20 response with Xeljanz 5 mg BID, compared to 24% of patients taking placebo (p≤0.05), at three months. In both studies, statistically significant improvements in ACR20 response was also seen with Xeljanz 5 mg BID compared to placebo at week 2, a secondary endpoint and the first post-baseline assessment (OPAL Broaden: 22% and 6% [p=0.0003], respectively; OPAL Beyond: 27% and 13% [p=0.0046], respectively).

“As a practicing rheumatologist, I’ve seen the significant physical impact psoriatic arthritis has on people living with the disease, and many patients are looking for additional therapeutic options,” said Philip Mease, M.D., Swedish Medical Center, University of Washington and study investigator. “I’m pleased that Xeljanz is now available for use in the treatment of this chronic condition.”

The safety profile observed in patients with active psoriatic arthritis treated with Xeljanz was consistent with the safety profile observed in rheumatoid arthritis patients. The most common adverse events observed occurring in greater than 3% of patients on Xeljanz 5 mg BID were nasopharyngitis, upper respiratory tract infection, headache and diarrhea.

“Psoriatic arthritis is a serious and debilitating chronic illness that should be diagnosed and treated early,” said Randy Beranek, president and CEO, National Psoriasis Foundation. “As an organization that advocates for people living with psoriatic arthritis, we welcome the availability of new therapies for treating this disease.”

Simponi the first biologic therapy to be approved for rheumatologic diseases !

We did know about the three 3 TNF inhinitors (namely-Infliximab, Etanercept and Adalimumab), the last still to be approved by US.

Like Infliximab and Etanercept, Adalimumab binds to TNFα preventing it from activating TNF receptors; adalimumab was constructed from a fully human monoclonal antibody, while infliximab is a mouse-human chimeric antibody and etanercept is a TNF receptor-IgG fusion protein. TNFα inactivation has proven to be important in down regulating the inflammatory reactions associated with autoimmune diseases. As of 2008 adalimumab has been approved by the FDA for the treatment of rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, Crohn's disease, moderate to severe chronic psoriasis and juvenile idiopathic arthritis.

Humira (brand name is an abbreviation of "Human Monoclonal Antibody in Rheumatoid Arthritis") is marketed in both preloaded 0.8 ml syringes and also in preloaded pen devices (called Humira Pen), both injected subcutaneously, typically by the patient at home. It cannot be administered orally, because the digestive system would destroy the drug. But its now the turn of Golimumab, a new fully human monoclonal antibody. Being a fully human MAb directed against TNF, Golimumab resembles Adalimumab (Humira, Abbott), which was the first such product to reach the market. Now the Canadian government has approved Golimumab along with ‘methotrexate’ for the treatment of three forms of Rheumatiod arthritis (Rheumatoid Arthritis, Ankylosing Spondylitis & Psoriatic Arthritis) and more over making this treatment the first biologic therapy to be approved.

With this approval in Canada, Simponi (Golimumb), in combination with methotrexate (MTX), is indicated for reducing the signs and symptoms in adult patients with moderately to severely active RA; reducing signs and symptoms in adult patients with moderately to severely active PsA, alone or in combination with MTX; and reducing signs and symptoms in adult patients with active AS who have had an inadequate response to conventional therapies.

FDA Approves Olumiant (baricitinib) 2 mg Tablets for the Treatment of Adults with Moderately-to-Severely Active Rheumatoid Arthritis

Eli Lilly and Company (NYSE: LLY) and Incyte Corporation (NASDAQ: INCY) announced today that the U.S. Food and Drug Administration (FDA) has approved the 2-mg dose of Olumiant (baricitinib), a once-daily oral medication for the treatment of adults with moderately-to-severely active rheumatoid arthritis (RA) who have had an inadequate response to one or more tumor necrosis factor (TNF) inhibitor therapies.  Use of Olumiant in combination with other Janus kinase (JAK) inhibitors or biologic disease-modifying antirheumatic drugs (bDMARDs), or with potent immunosuppressants such as azathioprine and cyclosporine is not recommended.  Olumiant may be used as monotherapy or in combination with methotrexate (MTX) or other non-biologic DMARDs.

"We are pleased to provide RA patients in the U.S. an effective treatment option with Olumiant, as people with RA who have had an inadequate response to TNF inhibitors are generally considered to be some of the most difficult to treat RA patients," said Christi Shaw, president, Lilly Bio-Medicines.

The Olumiant clinical trial program included the RA-BEACON study, a randomized, double-blind, placebo-controlled study in which patients were randomly assigned to receive Olumiant 2 mg, baricitinib 4 mg or placebo, in addition to conventional DMARDs that they were currently using.  This study included 527 patients who had an inadequate response or intolerance to one or more TNF inhibitor therapies.  Patients could have had prior therapy with other bDMARDs. 

The study results showed that significantly higher ACR20 response rates and improvement in all individual ACR20 component scores were observed at Week 12 with Olumiant.1 The study found that patients treated with Olumiant had significantly higher rates of ACR20 response versus placebo-treated patients at Week 12 (49% of Olumiant-treated patients versus 27% of placebo-treated patients).1Olumiant also demonstrated early symptom relief, with ACR20 responses seen as early as Week 1.1Patients treated with Olumiant reported significant improvements in physical function based on the Health Assessment Questionnaire Disability Index (HAQ-DI) (recording an average score of 1.71 before treatment and 1.31 at Week 12) compared to placebo-treated patients (who recorded an average score of 1.78 before treatment and 1.59 at Week 12). 

Olumiant is approved with a Boxed Warning for the risk of serious infections, malignancies and thrombosis. Serious infections leading to hospitalization or death, including tuberculosis and bacterial, invasive fungal, viral, and other opportunistic infections, have occurred in patients receiving Olumiant. Lymphoma and other malignancies have been observed in patients treated with Olumiant as well. Additionally, thrombosis, including deep venous thrombosis, pulmonary embolism and arterial thrombosis, some fatal, have occurred in patients treated with Olumiant.  Other warnings and precautions include gastrointestinal perforations, laboratory abnormalities (including neutropenia, lymphopenia, anemia, liver enzyme elevations, and lipid elevations) and a warning against the use of live vaccines with Olumiant.  The most common adverse events (occurring in greater than or equal to 1% of Olumiant 2 mg- and baricitinib 4 mg-treated patients in placebo-controlled trials) included upper respiratory tract infections, nausea, herpes simplex and herpes zoster. 

As part of the approval, the companies have agreed to conduct a randomized controlled clinical trial to evaluate the long-term safety of baricitinib in patients with rheumatoid arthritis.

"Despite the advancements we've seen in the RA treatment landscape over the past several decades, many patients are still failing to achieve their disease management goals," said Seth Ginsberg, co-founder and president of CreakyJoints and the Global Healthy Living Foundation. "As it's important for RA patients to have multiple treatment options available to best suit their disease characteristics and experiences, the approval of Olumiant is very encouraging for our community."

RA is a chronic, painful and progressive form of arthritis  It is estimated that about two-thirds of established RA patients will not reach clinical remission with their first TNF inhibitor therapy, and a significant percentage will not maintain efficacy as time goes on. 

"In my clinical practice, I continue to see patients who experience debilitating symptoms and who are waiting for a medicine that may be right for them," said Elizabeth L. Perkins, M.D., Rheumatology Care Center, Birmingham, Alabama. "Olumiant is an important option for rheumatologists to help address these patients' unmet needs."

"RA patients continue to experience unique challenges accessing the treatments prescribed by their healthcare providers. Therefore, we are determined to continue our work with stakeholders to demonstrate value across the healthcare system so providers have greater choice in prescribing treatments to fit individual patient needs," said Shaw.

Lilly will launch Olumiant in the U.S. by the end of the second quarter of 2018. The price of Olumiant will be 60% less than the leading TNF inhibitor.5 Lilly will be offering a patient support program, Olumiant Together™. For more information about this program, please call 1-844-Olumiant.

Incyte is now eligible to receive a $100 million milestone payment from Lilly as a result of the Olumiant approval, which Incyte expects to recognize in the second quarter of 2018. 

Methotrexate & Ocrelizumab combination a new hope for RA patients....

In recent days, I have seen many researchers are trying the combination of existing drugs in combination with a monoclonal antibodies for many diseases like cancer, rheumatoid arthritis and are successful too. As synthetic chemist I was interested in knowing about these monoclonal antibodies and found some interesting info, which I am sharing herewith...

About monoclonal antibodies :

monoclonal antibodies (mAb or moAb) are monospecific antibodies that are identical because they are produced by one type of immune cell that are all clones of a single parent cell. Given almost any substance, it is possible to create monoclonal antibodies that specifically bind to that substance; they can then serve to detect or purify that substance. This has become an important tool in biochemistry, molecular biology and medicine. When used as medications, the non-proprietary drug name ends in -mab.

The invention is generally accredited to Georges Köhler, César Milstein, and Niels Kaj Jerne in 1975; who shared the Nobel Prize in Physiology or Medicine in 1984 for the discovery. The key idea was to use a line of myeloma cells that had lost their ability to secrete antibodies, come up with a technique to fuse these cells with healthy antibody-producing B-cells, and be able to select for the successfully fused cells. In 1988 Greg Winter (Nat Rev Cancer 2001;1:118-129) and his team pioneered the techniques to humanize monoclonal antibodies, removing the reactions that many monoclonal antibodies caused in some patients. Interestingly, many monoclinical antibodies have been tried for rheumatoid arthritis, chrohn's disease and as anticancer agents.

Many monoclonal antibodies like infliximab, etanercept and adalimumab were tried for the rheumatoid arthritis now its interseting to note that Genentech and Biogen Idec reported positive outcome from ocrelizumab ( humanized anti-CD20) -MTX (Methotrexate - see the structure : this drug is a part of DMARD treatment meant for RA patients) combination study in RA. The results are significant because they are the first data from a large Phase III trial to show that a humanized antibody targeted at B-cells improves the signs and symptoms of rheumatoid arthritis. Hope patients suffering from RA and those are not responding will breathe a sigh of relief in the days to come...

Anti-inflammatory drugs may improve severity of depressive symptoms, study finds

Anti-inflammatory drugs similar to those used to treat conditions such as rheumatoid arthritis and psoriasis could in future be used to treat some cases of depression, concludes a review led by the University of Cambridge, which further implicates our immune system in mental health disorders.

Researchers from the Department of Psychiatry at Cambridge led a team that analysed data from 20 clinical trials involving the use of anti-cytokine drugs to treat a range of autoimmune inflammatory diseases. By looking at additional beneficial side-effects of the treatments, the researchers were able to show that there was a significant antidepressant effect from the drugs compared to a placebo based on a meta-analysis of seven randomised controlled trials. Meta-analyses of the other types of clinical trials showed similar results.

When we are exposed to an infection, for example influenza or a stomach bug, our immune system fights back to control and remove the infection. During this process, immune cells flood the blood stream with proteins known as cytokines. This process is known as systemic inflammation.

Even when we are healthy, our bodies carry trace levels of these proteins - known as 'inflammatory markers' - which rise exponentially in response to infection. Previous work from the team found that children with high everyday levels of one of these markers are at greater risk of developing depression and psychosis in adulthood, suggesting a role for the immune system, particularly chronic low-grade systemic inflammation, in mental illness.

Inflammation can also occur as a result of the immune system mistaking healthy cells for infected cells and attacking the body, leading to autoimmune inflammatory diseases such as rheumatoid arthritis, psoriasis and Crohn's disease. New types of anti-inflammatory drugs called anti-cytokine monoclonal antibodies and cytokine inhibitors have been developed recently, some of which are now routinely used for patients who respond poorly to conventional treatments. Many more are currently undergoing clinical trials to test their efficacy and safety.

The team of researchers carried out a meta-analysis of these clinical trials and found that the drugs led to an improvement in the severity of depressive symptoms independently of improvements in physical illness. In other words, regardless of whether a drug successfully treated rheumatoid arthritis, for example, it would still help improve a patient's depressive symptoms. Their results are published today in the journal Molecular Psychiatry.

Anti-inflammatory drugs may improve severity of depressive symptoms, study finds: Anti-inflammatory drugs similar to those used to treat conditions such as rheumatoid arthritis and psoriasis could in future be used to treat some cases of depression, concludes a review led by the University of Cambridge, which further implicates our immune system in mental health disorders.

New drug combination shows promise as effective, safe treatment for rheumatoid arthritis

A new drug combination for rheumatoid arthritis treats the disease just as well as other intensive treatment strategies but with less medication and fewer side effects at a significantly lower cost. Doctoral researcher Diederik De Cock (KU Leuven) describes the strategy in a new study published in Annals of Rheumatic Diseases.

Rheumatoid arthritis (RA) is a chronic auto-immune disease that causes pain and stiffness in the joints, fatigue, bone damage and, eventually, loss of mobility. RA afflicts around 1% of people in the western world; in Belgium, 80,000 to 100,000 people currently live with the disease.

Because there is no known cure for RA, physicians focus treatment on suppressing disease activity. Therapies have improved in recent years, and clinical studies show that intensive treatment of early RA can prevent joint damage and improve patients' quality of life.

In the two-year study, called 'CareRA' (Care in early RA), researchers and clinicians in the rheumatology unit at University Hospitals Leuven examined various therapies for early RA. Their goal: to find the optimal combination and dosage of three commonly prescribed antirheumatic drugs (methotrexate, sulfasalazine and leflunomide) in combination with glucocorticoids (a class of steroid hormones).

The researchers divided 290 early RA patients into three treatment groups. Each group received a different combination therapy: 'COBRA Classic' (methotrexate, sulfasalazine and a high first dose of glucocorticoids), 'COBRA Slim' (methotrexate and a moderate dose of glucocorticoids) or 'COBRA Avant-Garde' (methotrexate, leflunomide and a moderate dose of glucocorticoids).

We knew that,  Tofacitinib (see structure, formerly tasocitinib is a drug being investigated by Pfizer for the treatment of rheumatoid arthritis (RA), psoriasis,inflammatory bowel disease, and other immunological diseases, as well as for the prevention of organ transplant rejection. It is an inhibitor of the enzyme Janus kinase 3 (JAK3), which means that it interferes with the JAK-STAT signaling pathway that transmits information outside the cell into the cell nucleus, influencing DNA transcription.

Now Pfizer now claims that the drug has   met its key goals of reducing signs and symptoms of the condition in separate studies on patients over a 12-month and six-month period. Rheumatoid arthritis is a chronic inflammatory disease typically affecting joints.

The company's Oral Standard study involved 717 patients over a 12-month period with moderate-to-severe rheumatoid arthritis who had an inadequate response to the drug methotrexate. Meanwhile, the Oral Step study involved 399 patients over a six-month period with moderate-to-severe rheumatoid arthritis who did not have an adequate response to TNF inhibitor drugs.  Pfizer said no new safety signals emerged in the Oral Standard and Oral Step studies. A more detailed analysis off the data will be submitted to a future scientific meeting. 

The most common side effects of treatment with tofacitinib have included bronchitis, headache, infections, and gastrointestinal symptoms like nausea, vomiting, and diarrhea. More serious side effects in a mid-stage trial included lower levels of a type of white blood cell called neutrophils, higher cholesterol levels and increased creatinine levels.

Tofacitinib is a key developing drug for Pfizer and is also being studied as a potential treatment for psoriasis, inflammatory bowel disease, and renal transplant. A topical version of the drug is being studied as a psoriasis treatment and a dry eye disease treatment....

FDA Advisory Committee Recommends the Approval of Baricitinib 2mg, but not 4mg, for the Treatment of Moderately-to-Severely Active Rheumatoid Arthritis

Eli Lilly and Company (NYSE: LLY) and Incyte Corporation (NASDAQ: INCY) announced  that the U.S. Food and Drug Administration's (FDA) Arthritis Advisory Committee recommended approval of the 2-mg dose of baricitinib, a once-daily oral medication for the treatment of moderately-to-severely active rheumatoid arthritis (RA) for adult patients who have had an inadequate response or intolerance to methotrexate. While the Advisory Committee unanimously supported the efficacy of the 4-mg dose of baricitinib, it did not recommend approval of the 4-mg dose of baricitinib for the proposed indication based on the adequacy of the safety and benefit-risk profiles.

"We are confident that baricitinib, if approved, can help people in the U.S. manage the challenges of living with RA," said Christi Shaw, president of Lilly Bio-Medicines. "While we are disappointed with the Advisory Committee's assessment of the data for the 4-mg dose, we are confident in the positive benefit-risk profile of both the 2-mg and the 4-mg doses. We look forward to continuing our work with the FDA on our New Drug Application (NDA) and are hopeful that baricitinib will receive approval in the coming months."

Baricitinib 2-mg and 4-mg doses are approved in more than 40 countries, including the member states of the European Union and Japan.

For both doses, the Advisory Committee voted to support the assessment that baricitinib's data provide substantial evidence of efficacy. For the 2-mg dose, the Advisory Committee voted in favor of the assessment that baricitinib's safety data adequately support its approval. For the 4-mg dose, the Advisory Committee voted against the assessment that baricitinib's safety data was adequate to support its approval based on the proposed indication.

The Advisory Committee's recommendation was based on baricitinib's global development program, which included four completed Phase 3 studies. In total, 3,492 patients, who represented a range of treatment experiences, received baricitinib in the global RA development program. The Phase 3 studies evaluated baricitinib's treatment impact related to RA signs and symptoms, physical function, joint damage progression and other patient-reported outcomes. The Phase 3 program also evaluated recognized risks for RA patients, including serious infection, malignancy, major adverse cardiovascular events (MACE), venous thromboembolism (VTE), and gastrointestinal perforations, along with key laboratory changes. The safety profile of baricitinib is based on 7,860 patient-years of exposure.

"Despite advances in the management of RA over the last 20 years, which include early treatment, optimized use of traditional therapies for rheumatic disease and the advent of newer medications such as biologics, many patients are still struggling to meet treatment targets, and live with debilitating pain, fatigue and other symptoms of RA," said Peter Taylor, MA, PhD, professor, University of Oxford, an expert who attended the Advisory Committee Meeting. "Baricitinib could be a promising option for RA patients in the U.S. who are not achieving adequate disease control with currently available treatments."

The FDA is not required to follow the Advisory Committee's recommendation, but will consider it during its review of the NDA for baricitinib.

Pfizer seeks FDA support for its new anti-rheumatoid arthritis pill

Pfizer seeks FDA support for its new anti-rheumatoid arthritis pill: Pfizer is waiting for the Food and Drug Administration to approve its new pill for rheumatoid arthritis (RA) - the first oral biologic for treating this ailment.

Methotrexate drug holiday improves flu vaccine efficacy in rheumatoid arthritis patients

In continuation of my update on methotrexate

People with RA who stop taking methotrexate treatment for just two weeks after they have a seasonal flu shot can improve the vaccine's efficacy without increasing RA disease activity, according to new research findings presented this week at the 2017 ACR/ARHP Annual Meeting in San Diego.

Rheumatoid arthritis (RA) is a chronic disease that causes   pain,  stiffness,  welling, and limitation in the motion and function of multiple joints. Though joints are the principal body parts affected by RA, inflammation can develop in other organs as well. An estimated 1.3million Americans have RA, and the disease typically affects women twice as often as men.

Methotrexate, a widely used immunosuppressant, can lower vaccine efficacy in people with RA. So researchers in Seoul, Republic of Korea, set out to investigate whether patients with RA could improve their response to influenza vaccinations by temporarily pausing methotrexate use for two weeks after their flu shot.

"RA patients are more susceptible to infections, including seasonal flu, due to their underlying abnormal immune function and the treatment-associated immune suppression," said Jin Kyun Park, MD, Assistant Professor of Medicine at Seoul National University Hospital, and a lead author of the study. "RA patients taking methotrexate are at even higher risk of infection and infection-related complications, so it's important that they be vaccinated against preventable infectious diseases. However, the immune suppression decreases vaccine response.

To overcome this shortcoming, our group has been working on a novel immunization protocol for RA patients to optimize vaccine response,  including increasing immunogenicity of flu vaccines."

In this prospective, multicenter, randomized, parallel-group trial conducted from October 2016 to January 2017, 316 RA patients who were taking a stable methotrexate dose were randomly assigned to two groups: 156 continued their regular methotrexate and 160 discontinued their dose for two weeks after receiving their flu shot. All participants were vaccinated with a seasonal, quadrivalent influenza vaccine containing H1N1, H3N2, B-Yamagata and B-Victoria.

FDA approves Chelsea Therapeutics' Phase II protocol for CH-4051 antifolate in rheumatoid arthritis

Chelsea Therapeutics International, Ltd. announced the  confirmation by the U.S. FDA,  that its proposed Phase II protocol for CH-4051  in rheumatoid arthritis has been approved by the agency. Chelsea plans to initiate patient screening next month and initiating treatment in October.

This multi-national, double-blind, randomized Phase II trial of CH-4051, an orally available metabolically stable antifolate, is intended to evaluate the safety and efficacy of CH-4051 in a 250-patient head-to-head study against methotrexate (MTX). Patients with rheumatoid arthritis who are experiencing an inadequate response to MTX treatment will be randomized to receive daily oral doses of 0.3 mg, 1.0 mg, 3.0 mg or 3.0 mg plus folate of CH-4051 or 20 mg weekly dose of MTX plus folate supplement for 12 weeks following a two-week MTX-washout. The primary efficacy analysis will be conducted using the hybrid American College of Rheumatology, or ACR, score (hACR), which allows for a more comprehensive assessment of treatment benefit across all seven symptomatic and functional components of the standard ACR 20/50/70 evaluations historically used in RA trials.

"Although MTX is considered the standard of care in RA, both as a monotherapy and in combination with other RA treatments, the dosing and maximal therapeutic benefit of MTX is limited by well-documented tolerability issues, long-term safety concerns and variable bioavailability," commented Dr. Simon Pedder, president and CEO of Chelsea Therapeutics. "Given that CH-4051 is metabolically stable and that all of our preclinical and clinical work suggests enhanced absorption, dramatically increased potency and improved tolerability over MTX, we believe CH-4051 will be safe and highly efficacious in a historically treatment-resistant patient population."

Chelsea intends to conduct an un-blinded interim efficacy analysis after approximately 50% of patients in the two lower CH-4051 dose groups complete treatment and expect to report results from this analysis in the third quarter of 2011. Full study results, inclusive of all dose groups, are expected in mid-2012.

As previously reported, results from Chelsea's Phase I single and multiple ascending dose studies demonstrated that CH-4051 was well tolerated at doses up to and including 7.5mg, a dose range likely to be effective for multiple autoimmune disorders. The 5mg dose was as well tolerated as placebo. No serious adverse events occurred during the study and pharmacokinetic data indicated dose proportionate increases in plasma levels of CH-4051. Furthermore, it was revealed that plasma concentrations in the study were comparable to those seen in animal pharmacology studies in which CH-4051 demonstrated superior suppression of RA than both the maximally tolerated dose of methotrexate and equivalent doses of CH-1504 (see structure)....

AbbVie reports positive results from ABT-494 Phase 2 clinical trials in patients with rheumatoid arthritis

AbbVie (NYSE: ABBV), a global biopharmaceutical company, today announced results from two Phase 2 clinical trials evaluating its investigational selective JAK1 inhibitor, ABT-494, in patients with inadequate response to either methotrexate or TNF inhibitors. The clinical trials, BALANCE-I and BALANCE-II, achieved ACR20 at week 12 across all dose levels, except the lowest dose in BALANCE-II. BALANCE-I and BALANCE-II evaluated patients with moderate to severe rheumatoid arthritis with inadequate responses to prior anti-TNF (TNF-IR) or methotrexate (MTX-IR) treatment, respectively.

"We believe ABT-494 has the potential to become a best-in-class therapy, particularly in the most challenging patient population of TNF-inadequate responders," said Michael Severino, M.D., executive vice president, research and development and chief scientific officer, AbbVie. "We are encouraged by the results of our Phase 2 studies and we will advance ABT-494 to Phase 3 studies with a once-daily formulation."
