New treatment for a rare and aggressive cancer improves survival rates in breakthrough clinical trial

An innovative treatment significantly increases the survival of people with malignant mesothelioma, a rare but rapidly fatal type of cancer with few effective treatment options, according to results from a clinical trial led by Queen Mary University of London. 

The phase 3 clinical trial, led by Professor Peter Szlosarek at Queen Mary and sponsored by Polaris Pharmaceuticals, has unveiled a breakthrough in the treatment of malignant pleural mesothelioma (MPM), a rare and often rapidly fatal form of cancer with limited therapeutic options.  

Mick’s journey with mesothelioma: “I have five grandchildren and two great-grandchildren now – I wouldn’t want to miss all that.” 

The ATOMIC-meso trial, a randomised placebo-controlled study of 249 patients with MPM, found that a treatment – which combines a new drug, ADI-PEG20, with traditional chemotherapy – increased the median survival of participants by 1.6 months, and quadrupled the survival at 36 months, compared to placebo-chemotherapy.  

The findings are significant, as MPM has one of the lowest 5-year survival rates of any solid cancer of around 5-10%. This innovative approach marks the first successful combination of chemotherapy with a drug that targets cancer's metabolism developed for this disease in 20 years. 

MPM is a rare, aggressive cancer that affects the lining of the lungs and is associated with exposure to asbestos. It’s usually treated with potent chemotherapy drugs, but these are seldom able to halt the progression of the disease.  

The premise behind this new drug treatment is elegant in its simplicity – starving the tumour by cutting off its food supply. All cells need nutrients to grow and multiply, including amino acids like arginine. ADI-PEG20 works by depleting arginine levels in the bloodstream. For tumour cells that can't manufacture their arginine due to a missing enzyme, this means their growth is thwarted.  

The ATOMIC-meso trial is the culmination of 20 years of research at Queen Mary’s Barts Cancer Institute that began with Professor Szlosarek’s discovery that malignant mesothelioma cells lack a protein called ASS1, which enables cells to manufacture their own arginine. He and his team have since dedicated their efforts to using this knowledge to create an effective treatment for patients with MPM. 

Professor Szlosarek said:  “It's truly wonderful to see the research into the arginine starvation of cancer cells come to fruition. This discovery is something I have been driving from its earliest stages in the lab, with a new treatment, ADI-PEG20, now improving patient lives affected by mesothelioma. I thank all the patients and families, investigators and their teams, and Polaris Pharmaceuticals for their commitment to defining a new cancer therapy.” 

Dr Tayyaba Jiwani, Science Engagement Manager at Cancer Research UK, said:  "This study shows the power of discovery research which allows us to dig deep into the biology of mesothelioma to uncover vulnerabilities that we can now target with ADI-PEG20.  

"Cancer Research UK is delighted to have funded the early stages of this research, including a preliminary clinical trial which established the safety and effectiveness of this drug." 

There are ongoing studies assessing ADI-PEG20 in patients who have sarcoma or glioblastoma multiforme (a type of brain tumour) and other cancers dependent on arginine. The success of this novel chemotherapy in MPM also suggests that the drug may be of benefit in the treatment of multiple other types of cancer.  

Mick’s journey with mesothelioma  

Mick worked in a factory boiler room in the 1970s, where he was exposed to asbestos. In 2018, he visited his doctor after he began to feel unwell and had lost three stone in weight. He became anaemic and was eventually diagnosed with mesothelioma. 

“It was a bit of a shock: I was given four months to live,” Mick explains. His doctor referred him to Professor Szlosarek, who enrolled him in the ATOMIC-meso trial. “I always believed in Peter. I said: ‘I’m in it to win it – you’re not getting rid of me.’ And here I am five years later.” 

For two years, Mick visited St Bartholomew’s Hospital every week, accompanied by his wife, Jackie, or one of his children or grandchildren. “I’d have two injections of the new treatment – one in each arm. I didn’t have any serious side effects,” Mick explains. “I met many of the other people on the trial. Over time, some of them disappeared. But I kept going.”  

Mick was awarded compensation from his former employer responsible for the asbestos exposure that ultimately led to his mesothelioma. Around 80% of mesothelioma cases are caused by workplace exposure. 

Two and a half years after Mick enrolled on the ATOMIC-meso trial, his mesothelioma returned and he received a second course of treatment, this time immunotherapy. He experienced more side effects with this therapy, including encephalitis. But his cancer remains under control, and recently he was able to celebrate his 80th birthday. Professor Szlosarek and his team plan to study why certain patients, such as Mick, benefit so greatly from ADI-PEG20, in the hope of discovering how to extend this benefit to more people.  

Mick says: “This trial has changed the lives of people with mesothelioma, allowing us to live longer. I have five grandchildren and two great-grandchildren now – I wouldn’t want to miss all that.”

Ipsen’s Onivyde Regimen, a Potential New Standard-of-Care First-Line Therapy in Metastatic Pancreatic Adenocarcinoma, Approved by FDA




Ipsen (Euronext: IPN; ADR: IPSEY) announced today that the U.S. Food and Drug Administration (FDA) has approved the supplemental new drug application for Onivyde (irinotecan liposome injection) plus oxaliplatin, fluorouracil and leucovorin (NALIRIFOX) as a first-line treatment in adults living with metastatic pancreatic adenocarcinoma (mPDAC). This is the second approval for an Onivyde regimen in mPDAC, following the FDA’s approval in 2015 of Onivyde plus fluorouracil and leucovorin following disease progression with gemcitabine-based therapy.

“The results from the Phase III NAPOLI 3 trial represent the first positive data for an investigational regimen in first-line metastatic pancreatic adenocarcinoma versus the currently approved nab-paclitaxel and gemcitabine regimen,” said Christelle Huguet, EVP and Head of Research and Development, Ipsen. “With today’s approval, this Onivyde (NALIRIFOX) regimen can now offer a potential new standard-of-care treatment option with proven survival benefits for people living with metastatic pancreatic adenocarcinoma in the U.S.”

Pancreatic adenocarcinoma (PDAC) is the most common type of cancer that forms in the pancreas, with more than 60,000 people diagnosed in the U.S. each year and nearly 500,000 people globally.3,4 Since there are no specific symptoms in the early stages, PDAC is often detected late and after the disease has spread to other parts of the body (metastatic or stage IV).5 Characterized as a complex cancer due to rapid tumor progression, limited genetic targets and multiple resistance mechanisms,6 mPDAC has a poor prognosis with fewer than 20% of people surviving longer than one year.4,5 Overall, pancreatic cancer has the lowest five-year survival rate of all cancer types globally and in the U.S.4,5

“Metastatic pancreatic adenocarcinoma is a difficult disease to manage with very few available treatment options. Given the reality of this aggressive form of cancer and the complexity of the disease, every advance in the treatment landscape represents a meaningful improvement in patient outcomes.” said Dr. Zev Wainberg, Professor of Medicine and Co-Director of the UCLA GI Oncology Program. “The approval of this Onivyde regimen is an important milestone for people living with mPDAC, their families and healthcare providers, with the NAPOLI 3 trial having demonstrated survival benefits versus a current standard of care treatment option.”

“We are pleased that the U.S. Food and Drug Administration has issued this new approval of the NALIRIFOX regimen. With each new approved treatment, there is more hope for those who will be diagnosed in the future and people currently living with pancreatic cancer may have more time with their loved ones,” said Julie Fleshman, JD, MBA, President and CEO of Pancreatic Cancer Action Network (PanCAN), a patient advocacy organization committed to providing evidence-based information and resources to patients and caregivers, along with advancing research to improve patient outcomes. “We are thankful to the patients who participated in this clinical trial as they play a crucial role in advancing treatments for pancreatic cancer.”

Zevra Therapeutics Announces Resubmission of Arimoclomol New Drug Application to the U.S. Food and Drug Administration







Zevra Therapeutics, Inc. (NasdaqGS: ZVRA) a rare disease therapeutics company, today announced it resubmitted its New Drug Application (NDA) for arimoclomol, an investigational therapeutic candidate for the treatment of Niemann-Pick disease type C (NPC) to the U.S. Food and Drug Administration (FDA) on December 22, 2023. Based on standard NDA resubmission review timelines, an acknowledgment letter from the FDA that the resubmission is complete and setting the PDUFA date is expected within 30 days. Zevra expects the NDA to be classified as a Class II submission which would be subject to a review period by the FDA within six months from the date of submission.

“The Zevra team has worked diligently to deliver a high quality and thorough resubmission of the NDA for arimoclomol following multiple interactions with the FDA and after incorporating direction from the agency,” said Neil McFarlane, President and Chief Executive Officer of Zevra. “We continue to accelerate our launch preparations in anticipation of FDA approval, and believe we are one step closer to getting arimoclomol into the hands of patients who are seeking a treatment.”

“Zevra has engaged with the advocacy community, elevating the patient voice throughout arimoclomol’s development process,” said Daniel Gallo, Ph.D., Zevra’s Senior Vice President of Medical Affairs and Advocacy. “The advocacy community’s input has been instrumental in building awareness of the need for approved treatments that address the unmet needs of individuals and their caregivers living with this debilitating condition.”

Zevra believes it has addressed the issues previously raised by the FDA in the complete response letter by providing additional evidence to support the use of the Niemann-Pick type C Clinical Severity Scale (NPCCSS) and, conducting additional studies used to support the potential mechanism of action. Additionally, new data included in the resubmission comes from multiple non-clinical studies, natural history comparisons, real-world data generated from the ongoing early access programs in the United States and the European Union, as well as data from the four-year open-label extension of the Phase 2/3 clinical trial (NCT02612129). Results from this open-label trial suggest that arimoclomol reduces the long-term progression of NPC.

Arimoclomol has been evaluated in a total of 21 studies across a range of Phase 1, 2 or 3 clinical trials evaluating its safety and efficacy across more than 600 subjects in NPC, other disease or healthy subjects. The primary efficacy trial evaluating arimoclomol for the treatment of NPC was a Phase 2/3 double-blind, placebo-controlled trial (CT-ORZY-NPC-002) of arimoclomol in 50 patients with NPC.

Journey Medical Corporation Submits New Drug Application to FDA for DFD-29 to Treat Rosacea



Journey Medical Corporation,  announced that the Company has submitted,  a New Drug Application (“NDA”) to the FDA seeking approval for DFD-29 (Minocycline Hydrochloride Modified Release Capsules, 40 mg) for the treatment of inflammatory lesions and erythema of rosacea in adults. DFD-29 is being developed in collaboration with Dr. Reddy’s Laboratories Ltd.




“This NDA submission is a significant milestone for Journey Medical and we look forward to collaborating with the FDA during its review to bring DFD-29, a potentially differentiated, best-in-class oral rosacea treatment, one step closer to patients. Based on the data seen in our pivotal trials, DFD-29 could fundamentally improve the treatment paradigm for patients suffering from both inflammatory lesions and erythema (redness) from rosacea,” said Claude Maraoui, Co-Founder, President and Chief Executive Officer of Journey Medical.

The NDA submission is supported by positive data from Journey Medical’s two DFD-29 Phase 3 clinical trials for the treatment of rosacea. The Phase 3 clinical trials achieved all co-primary and secondary endpoints, and subjects completed the 16-week treatment with no significant safety issues. DFD-29 demonstrated statistical superiority over both the current standard-of-care treatment, Oracea® 40 mg capsules, and placebo for Investigator’s Global Assessment treatment success as well as the reduction in the total inflammatory lesion count in both studies. On a secondary endpoint related to erythema (redness) assessment, DFD-29 showed statistically significant reduction in Clinician’s Erythema Assessment (CEA) compared to placebo in both clinical trials.

Rosacea, which affects approximately 16 million people in the United States according to the National Rosacea Society, is a long-term, inflammatory skin condition that causes small, red, pus-filled bumps, redness and visible blood vessels in the face. DFD-29 has the potential to become the only oral, systemic therapy to address both inflammatory lesions and erythema (redness) from rosacea, as demonstrated in the clinical trials.

FDA Grants Soligenix Fast Track Designation for Dusquetide in the Treatment of Oral Lesions of Behçet's Disease

Soligenix, Inc. (Nasdaq: SNGX) (Soligenix or the Company), a late-stage biopharmaceutical company focused on developing and commercializing products to treat rare diseases where there is an unmet medical need, announced today that its SGX945 (dusquetide) development program for the treatment of oral lesions of Behçet's Disease has received "Fast Track" designation from the U.S. Food and Drug Administration (FDA).




Fast track is a designation that the FDA reserves for a drug intended to treat a serious or life-threatening condition and one that demonstrates the potential to address an unmet medical need for the condition. Fast track designation is intended to facilitate the development and expedite the review of new drugs and biologics. For instance, should events warrant, Soligenix will be eligible to submit a new drug application (NDA) for SGX945 on a rolling basis, permitting the FDA to review sections of the NDA prior to receiving the complete submission. Additionally, NDAs for fast track development programs ordinarily will be eligible for priority review, which imparts an abbreviated review time of approximately six months.

"We are very pleased to have SGX945 in Behçet's Disease granted fast track designation from the FDA," stated Christopher J. Schaber, PhD, President and Chief Executive Officer of Soligenix. "As demonstrated by the granting of the designation, our previous studies with dusquetide in oral mucositis have clearly validated the biologic activity in aphthous ulcers induced by chemotherapy and radiation. Behçet's disease is an unmet medical need in which the underlying vasculitis leads to ulceration of the mucous membranes and skin, with up to 18,000 people in the U.S. and as many as one million people worldwide affected by this incurable disease. Given our promising results with aphthous ulcers in oral mucositis, we are hopeful dusquetide will have a role to play in helping underserved patients suffering from this difficult to treat and chronic disease and look forward to initiating the Phase 2 clinical study in 2024."

About Dusquetide

Dusquetide (the active ingredient in SGX945 (Behçet's disease) and SGX942 (oral mucositis)) is an innate defense regulator (IDR), a new class of short, synthetic peptides. It has a novel mechanism of action whereby it modulates the body's reaction to both injury and infection towards an anti-inflammatory, anti-infective, and tissue healing response. IDRs have no direct antibiotic activity but, by modulating the host's innate immune system responses, increase survival after infections caused by a broad range of bacterial Gram-negative and Gram-positive pathogens. It also accelerates resolution of tissue damage following exposure to a variety of agents including bacterial pathogens, trauma, and chemo- and/or radiation therapy. Preclinical efficacy and safety have been demonstrated in numerous animal disease models including mucositis, colitis, macrophage activation syndrome (MAS) as well as bacterial infections. In addition, potential anti-tumor activity has been demonstrated in multiple in vitro and in vivo xenograft studies.

Dusquetide has demonstrated safety and tolerability in a Phase 1 clinical study in 84 healthy human volunteers. In Phase 2 and 3 clinical studies with SGX942 in over 350 subjects with oral mucositis due to chemoradiation therapy for head and neck cancer, positive efficacy results were demonstrated, including potential long-term ancillary benefits.

Soligenix has a strong intellectual property position in the IDR technology platform, including composition of matter for dusquetide and related analogs. Dusquetide was developed pursuant to discoveries made by Professors B. Brett Finlay, PhD and Robert Hancock, PhD of the University of British Columbia, Canada.

FDA Approves Augtyro (repotrectinib) for the Treatment of Locally Advanced or Metastatic ROS1-Positive Non-Small Cell Lung Cancer (NSCLC)

Bristol Myers Squibb (NYSE: BMY) announced  the U.S. Food and Drug Administration (FDA) approval of  Augtyro (repotrectinib) for the treatment of adult patients with locally advanced or metastatic ROS1-positive non-small cell lung cancer (NSCLC). Administered as an oral therapy, Augtyro is a tyrosine kinase inhibitor (TKI) targeting ROS1 oncogenic fusions.




The approval is based on the TRIDENT-1 study, an open-label, single-arm, Phase 1/2 trial that evaluated Augtyro in TKI-naïve and TKI-pretreated patients.2 In TKI-naïve patients (n=71), the primary endpoint of objective response rate (ORR), defined as the percentage of people treated within a certain period of time whose tumor size decreased (partial response) or who no longer have signs of cancer (complete response),was 79% (95% Confidence Interval [CI]: 68 to 88).1,3 The median duration of response (mDOR) was 34.1 months. Among patients pretreated with one prior ROS1 TKI and no prior chemotherapy (n=56), the ORR was 38% (95% CI: 25 to 52) and the mDOR was 14.8 months.Among those who had measurable central nervous system (CNS) metastases at baseline, responses in intracranial lesions were observed in 7 of 8 TKI-naïve patients (n=71) and 5 of 12 of those who were TKI-pretreated (n=56).

“New treatment options continue to be needed for patients with ROS1 fusion-positive NSCLC that support important clinical goals, including achieving durable therapeutic responses,” said Jessica J. Lin, MD, TRIDENT-1 primary investigator and attending physician at the Center for Thoracic Cancers at Massachusetts General Hospital and Assistant Professor of Medicine at Harvard Medical School.4,5,6,7 “Based on the data we have seen in the TRIDENT-1 trial, repotrectinib has the potential to become a new standard of care option for patients with locally advanced or metastatic ROS1 fusion-positive lung cancer.”1

Augtyro is associated with the following Warnings & Precautions: central nervous system (CNS) effects, interstitial lung disease (ILD)/pneumonitis, hepatotoxicity, myalgia with creatine phosphokinase elevation, hyperuricemia, skeletal fractures, and embryo-fetal toxicity.1 Please see Important Safety Information below.

“While progress has been made in the treatment of NSCLC over the past decade, there is still a need to address this particularly difficult-to-treat form of the disease with innovative science and a targeted approach,” said Samit Hirawat, MD, executive vice president, chief medical officer, Global Drug Development, Bristol Myers Squibb.6,7 “As the only approved next-generation TKI for ROS1-positiveNSCLCpatients, Augtyro builds on our legacy of delivering transformational therapies for patients with thoracic cancers.”6,8,9

“ROS1-positive NSCLC patients and their families face a stressful journey because our cancer can be difficult to treat, especially when it spreads to the brain,” said Janet Freeman-Daily, co-founder and president of The ROS1ders, a patient advocacy organization.10 “Today’s approval brings a new treatment option for the ROS1-positive patient community, which gives us hope for more time with loved ones.”

Augtyro is designed to minimize interactions that can lead to certain forms of treatment resistance in ROS1-positive metastatic NSCLC patients. Itis expected to be available to patients in the U.S. in mid-December 2023. Bristol Myers Squibb thanks the patients and investigators involved in the TRIDENT-1 clinical trial program.

Defender Pharmaceuticals, Inc. (the “Company” or “Defender”), a privately held life sciences company based in St. Louis, today announced the issuing of a Complete Response Letter (CRL) , by the U.S. Food and Drug Administration (FDA) to the Company’s New Drug Application (NDA) for intranasal scopolamine (DPI-386) for the prevention of nausea and vomiting induced by motion in adults.




“Following our review of the CRL, we plan on scheduling a formal meeting with the FDA to fully understand the issues raised in the CRL so we can develop and implement a comprehensive action plan,” said Barry I. Feinberg, M.D., President & CEO of Defender Pharmaceuticals. “We remain confident that our intranasal scopolamine is a safe and effective therapy for the prevention of motion sickness, and we will work closely with the FDA to ensure that we can bring this innovative new product to the market.”

About intranasal scopolamine (DPI-386) Development Program
Defender has worked with the United States Naval Medical Research Unit (NAMRU-D) and the National Aeronautics and Space Administration (NASA) on its intranasal scopolamine development program that is focused on specific military personnel and astronauts.

To date, more than 1,300 patients have participated in Defender clinical studies, including over 500 participants in the DPI-386-MS-33 study. Given the successful outcome of DPI-386-MS-33, Defender has submitted a New Drug Application (NDA) to the Food and Drug Administration (FDA) for DPI-386 Nasal Gel for the prevention of nausea and vomiting induced by motion in adults.

Defender is also developing intranasal formulations designed to treat a wide variety of indications. We believe these new products have the potential to help safeguard health across civilian and military populations.

About Motion-Related Discomfort
Certain motions cause discomfort in individuals while engaged in various leisure or travel-related activities. Most forms of travel, whether on land, in the air, or on the water, can trigger symptoms such as nausea and vomiting (example: flying, boating/fishing, car, bus, and train). Symptoms induced by motion can also have a detrimental impact on the ability of various military personnel and astronauts to perform assigned duties, potentially impacting readiness and negatively impacting resources. Motion-related discomfort is a common and transient response to unfamiliar or unnatural motion or contradictory spatial sensory information, resulting in decrements to performance of tasks, pallor, cold sweating, nausea and vomiting. Prolonged exposure to certain motions may induce sopite-related symptoms such as loss of drive and concentration, drowsiness, sleepiness, apathy, depression, and a feeling of impending doom.

Lykos Therapeutics Announces FDA Acceptance and Priority Review of New Drug Application for MDMA-Assisted Therapy for PTSD




Lykos Therapeutics (formerly MAPS Public Benefit Corporation) ("Lykos"), a company dedicated to transforming mental healthcare, announced that the U.S. Food and Drug Administration ("FDA") has accepted its new drug application ("NDA") for midomafetamine capsules ("MDMA") used in combination with psychological intervention, which includes psychotherapy (talk therapy) and other supportive services provided by a qualified healthcare provider for individuals with post-traumatic stress disorder ("PTSD"). The FDA has granted the application priority review and has assigned a Prescription Drug User Fee Act ("PDUFA") target action date of August 11, 2024. If approved, this would be the first MDMA-assisted therapy and psychedelic-assisted therapy.

"Securing priority review for our investigational MDMA-assisted therapy is a significant accomplishment and underscores the urgent unmet need for new innovation in the treatment of PTSD," said Amy Emerson, chief executive officer of Lykos Therapeutics. "We remain focused on working with the FDA through the review process and preparing for a controlled launch with an emphasis on quality should this potential treatment be approved."

The NDA submission included results from numerous studies including two randomized, double-blind, placebo-controlled Phase 3 studies (MAPP1 and MAPP2) evaluating the efficacy and safety of MDMA used in combination with psychological intervention versus placebo with therapy in participants diagnosed with severe or moderate to severe PTSD, respectively. Both MAPP1 and MAPP2 studies met their primary and secondary endpoints and were published in Nature Medicine. 1, 2 The primary endpoint for both studies was to assess changes in PTSD symptom severity as measured by the change from baseline in Clinician-Administered PTSD Scale for DSM-5 ("CAPS-5"). The key secondary endpoint of both studies was to assess improvement in functional impairment associated with PTSD as measured by the change from baseline in the Sheehan Disability Scale ("SDS"). No serious adverse events were reported in the MDMA group in either study.

The FDA grants priority review for drugs that, if approved, would represent significant improvements in the safety or effectiveness of the treatment, diagnosis, or prevention of serious conditions when compared to standard applications. 

MDMA-assisted therapy has not been approved by any regulatory agency. The safety and efficacy of MDMA-assisted therapy has not been established for the treatment of PTSD. Investigational MDMA-assisted therapy is also being studied in other indications.

About MDMA-Assisted Therapy
MDMA (3,4-methylenedioxymethamphetamine) is not new to mental health professionals. MDMA is an entactogen— a class of psychoactive compounds that are differentiated from classic psychedelics (i.e., psilocybin, mescaline and LSD) and are defined based on their mechanism and known effects of increasing self-awareness leading to introspection and personal reflection.27,,28 In the 1970's and early 1980's MDMA was used in conjunction with talk therapy by mental health providers to enhance patients' access, processing, and communication of difficult emotions and experiences.29 In 1985, the U.S. Drug Enforcement Administration ("DEA") made MDMA a Schedule I drug under the Controlled Substances Act preventing it from being used for recreational or medical use. 30 Since then, research has shown the unique properties of MDMA allow it to act as a powerful catalyst to support psychotherapy by helping diminish the brain's fear response allowing people to access and process painful memories without being overwhelmed. 31 However, additional clinical trials would be needed to secure regulatory review and potential approval.

Lykos, with longstanding roots in advocacy for psychedelic medicine, pioneered the first randomized, double-blind, placebo controlled clinical trials evaluating the efficacy and safety of MDMA-assisted therapy as an investigational modality using midomafetamine (MDMA) in combination with psychological intervention to treat PTSD.

With a growing body of evidence supporting the potential medical use of MDMA, in 2017 the FDA granted the company's investigational MDMA-assisted therapy Breakthrough Therapy designation, a process designed to expedite the development and review of drugs intended to treat serious conditions for which preliminary scientific evidence indicates that it may demonstrate a substantial improvement over available therapies. If approved by the FDA, the U.S. Drug Enforcement Administration ("DEA") would be required to reschedule MDMA making it available for prescription medical use.

Blood Test to Predict Schizophrenia Shows Promise

Researchers say they have developed a blood test for schizophrenia.

More than 3 million people in the United States have schizophrenia, a disorder marked by hallucinations and delusions, or a related psychotic illness.

The new test, which is expected to be available later this year from MindX Sciences, identifies markers in the blood that objectively measure a person's risk for schizophrenia, allowing doctors to tailor treatments to their individual biology.

"Schizophrenia is hard to diagnose, especially early on, and matching people to the right treatment from the beginning is very important," said senior study author Dr. Alexander Niculescu, a professor of psychiatry and medical neuroscience at Indiana University School of Medicine in Indianapolis.

"Psychosis usually manifests in young adulthood -- a prime period of life," he explained in a university news release. "Stress and drugs, including marijuana, are precipitating factors on a background of genetic vulnerability. If left unchecked, psychosis leads to accumulating biological damage, social damage and psychological damage."

His team published its research Feb. 8 in the journal Molecular Psychiatry.

For their study, they followed psychiatric patients for more than a decade, identifying biomarkers that predicted high rates of hallucination and delusions, as well as future related hospitalizations. They also examined which biomarkers were targets of existing drugs.

The work builds on previous studies by Niculescu, who is also a staff psychiatrist at the Veterans Administration Medical Center in Indianapolis, and his colleagues over the past two decades.

They have examined blood biomarkers for other psychiatric issues, including anxiety, post-traumatic stress disorder (PTSD), memory disorders and suicide risk.

In general, Niculescu said, the best biomarkers were better predictors than standard scales used to evaluate someone who has hallucinations or delusions.

"Fortunately, biologically some of the existing medications work quite well if initiated early in the right patients," he said. "Social support is also paramount, and once that and medications are in place, psychological support and therapy can help as well."

While Niculescu said there is still much to learn, there is reason for optimism in this era of emerging precision psychiatry.

Liquidia Corporation Provides Update on New Drug Application for Yutrepia (treprostinil) inhalation powder


Liquidia Corporation (the Company) (NASDAQ: LQDA) announced  the U.S. Food and Drug Administration (FDA) providing  an update on its review of the New Drug Application (NDA) for Yutrepia™ (treprostinil) inhalation powder to treat pulmonary arterial hypertension (PAH) and pulmonary hypertension associated with interstitial lung disease (PH-ILD). The FDA informed the Company that it is confirming the process for adding the PH-ILD indication as an amendment to the NDA for Yutrepia. Accordingly, the FDA is not able to issue an action letter in time to meet the previously issued Prescription Drug User Fee Act (PDUFA) goal date of January 24, 2024, and their review remains ongoing. The FDA did not request any additional clinical data to support the NDA and did not issue a new PDUFA goal date.

Dr. Roger Jeffs, Chief Executive Officer, said: “We are in active communication with the FDA regarding the process we followed to amend our NDA to add PH-ILD to the labeled indication. Whether the NDA is amended or supplemented, we will continue to prepare for the final FDA approval of Yutrepia to treat both PAH and PH-ILD patients following the expiration of regulatory exclusivity for Tyvaso® on March 31, 2024. As communicated by the tentative approval to treat PAH, Yutrepia has already met the regulatory standards for quality, safety and efficacy. We remain committed to addressing the unmet needs across all patients whose lives may be improved by the unique benefits of Yutrepia.”

On November 5, 2021, the FDA issued a tentative approval for Yutrepia for the treatment of PAH to improve exercise ability in adult patients with New York Heart Association (NYHA) Functional Class II-III symptoms. In July 2023, Liquidia filed an amendment to its New Drug Application for Yutrepia, seeking to add PH-ILD to the label. The FDA previously confirmed that Yutrepia may include the treatment of PH-ILD to the proposed label for Yutrepia without additional clinical studies.

Yutrepia also remains subject to ongoing litigation. Liquidia filed a request for Judge Andrews of the U.S. District Court for the District of Delaware (District Court) to set aside the injunction that was instituted in August 2022 tied to litigation filed by United Therapeutics (UTHR) alleging patent infringement of U.S. Patent No. 10,716,793 (the ‘793 Patent) in Case No. 1:20-cv-00755-RGA (the Original Hatch-Waxman Litigation). On December 20, 2023, the United States Court of Appeals for the Federal Circuit (CAFC) affirmed the earlier decision by the Patent Trial and Appeal Board (PTAB), which found all claims of the ‘793 Patent to be unpatentable due to the existence of prior art cited by Liquidia in inter partes review proceedings.

Additionally, in September 2023, UTHR filed a second complaint for patent infringement in District Court in Case No. 1:23-cv-00975-RGA (the New Hatch-Waxman Litigation). As of January 22, 2024, the only patent at issue is U.S. Patent No. 11,826,327 (the ‘327 Patent) which issued November 30, 2023. UTHR has stipulated to the dismissal of the ‘793 Patent from the New Hatch-Waxman Litigation as a result of the CAFC decision affirming invalidity of the '793 Patent. The ’327 Patent, the sole remaining patent at issue in the New Hatch-Waxman Litigation, was not issued before Liquidia submitted the NDA for Yutrepia in January 2020 to treat PAH. Therefore, the Company believes that final FDA approval for Yutrepia will not be subject to any statutory 30-month stay arising from the New Hatch-Waxman Litigation per Section 505(c)(3)(C) of the Federal Food, Drug and Cosmetic Act.

FDA Approves Eohilia (budesonide oral suspension) for the Treatment of Eosinophilic Esophagitis

 Takeda (TSE:4502/NYSE: TAK)   announced the U.S. Food and Drug Administration (FDA)   approval of Eohilia (budesonide oral suspension), the first and only FDA-approved oral therapy for people 11 years and older with eosinophilic esophagitis (EoE).1 It will be available in 2 mg/10 mL convenient, single-dose stick packs by the end of February.




Eohilia is a corticosteroid indicated for 12 weeks of treatment in patients 11 years and older with EoE.1 Developed specifically for EoE, Eohilia’s novel formulation of budesonide confers thixotropic properties – flowing more freely when shaken and returning to a more viscous state when swallowed.1,2

“Various formulations of corticosteroids have been used in the past to manage EoE, but in an off-label capacity and using multiple delivery options. With Eohilia, it’s gratifying to now have an FDA-approved treatment specifically formulated for a consistent dose delivery with demonstrated ability to address esophageal inflammation and EoE dysphagia symptoms,” said Ikuo Hirano, MD, professor of medicine and director of the Kenneth C. Griffin Esophageal Center in the Division of Gastroenterology and Hepatology at Northwestern University Feinberg School of Medicine. “As the treatment needs and goals of patients with EoE can vary, I welcome the flexibility that Eohilia offers as an oral medication.”

The FDA approval of Eohilia 2 mg twice daily is based on efficacy and safety data from two multicenter, randomized, double-blind, parallel-group, placebo-controlled 12-week studies (Study 1 and Study 2) in patients (ages 11 to 56 and 11 to 42, respectively) with EoE.1 In both studies, patients received at least one dose of either Eohilia 2 mg twice daily or placebo orally twice daily. Efficacy endpoints included histologic remission (peak eosinophil count of ≤6 per high-powered field across all available esophageal levels) and the absolute change from baseline in patient-reported Dysphagia Symptom Questionnaire (DSQ) combined score after 12 weeks of treatment. The DSQ measures how often a patient with EoE has trouble swallowing and the behavioral adaptations they subsequently use, as reported directly by patients.3

Significantly more patients receiving Eohilia achieved histologic remission vs. placebo in Study 1 (53.1% vs. 1%).1 In Study 2, 38% of Eohilia patients achieved histologic remission vs. 2.4% of those in the placebo group. Absolute change from baseline in DSQ combined score in the Eohilia vs. placebo groups in Study 1 was -10.2 (1.5) vs. -6.5 (1.8) and in Study 2, -14.5 (1.8) vs. -5.9 (2.1). During the last two weeks of each study, more patients receiving Eohilia experienced no dysphagia or only experienced dysphagia that “got better or cleared up on its own” as compared to placebo, as measured by the DSQ. Eohilia has not been shown to be safe and effective for the treatment of EoE for longer than 12 weeks. The most common adverse reactions (≥2% of patients receiving Eohilia and at a rate greater than placebo) in Study 1 included: respiratory tract infection (13%), gastrointestinal mucosal candidiasis (8%), headache (5%), gastroenteritis (3%), throat irritation (3%), adrenal suppression (2%) and erosive esophagitis (2%). The safety profile of Eohilia in Study 2 was generally similar to Study 1.1

“For most of us, eating is a simple experience. But for people living with eosinophilic esophagitis, sitting down for a meal can include painful and difficult swallowing, chest pain and a choking sensation,” said Brandon Monk, senior vice president and head, U.S. Gastroenterology Business Unit, Takeda. “With Eohilia, patients and their physicians now have the first and only FDA-approved oral treatment option for EoE that was shown during two 12-week clinical studies to reduce esophageal inflammation and improve the ability to swallow.”

EoE is a chronic, immune-mediated, inflammatory disease localized in the esophagus.4 Although the exact cause is unknown, it is believed to be triggered by a variety of stimuli including certain foods and environmental allergens.5,6 The chronic inflammation of EoE can lead to a range of symptoms, which can vary by person and age, and include difficulty swallowing, vomiting and pain.7 Identifying EoE can be complex and delayed diagnosis is common among patients. If left untreated, the inflammation of EoE can worsen and narrow the esophagus, which can lead to food impaction (when food becomes stuck in the esophagus).8,9 In fact, EoE is the leading cause of emergency room visits for food impaction.10

Takeda is assessing the financial impacts of the approval, including a reversal of impairment loss for intangible assets, on the fiscal year ending on March 31, 2024 (FY2023), but does not anticipate the impact to be material.

FDA Approves Airsupra (albuterol/budesonide) Metered-Dose Inhaler to Reduce the Risk of Asthma Exacerbations

Airsupra (albuterol/budesonide), formerly known as PT027, has been approved in the US for the as-needed treatment or prevention of bronchoconstriction and to reduce the risk of exacerbations in people with asthma aged 18 years and older.

The approval by the Food and Drug Administration (FDA) was based on results from the MANDALA and DENALI Phase III trials. In MANDALA, Airsupra significantly reduced the risk of severe exacerbations compared to albuterol in patients with moderate to severe asthma when used as an as-needed rescue medication in response to symptoms. Importantly, in the secondary endpoint of mean annualised total systemic corticosteroid exposure, Airsupra demonstrated a significant reduction compared to albuterol at the approved dose of 180mcg albuterol/160mcg budesonide. In DENALI, Airsupra significantly improved lung function compared to the individual components albuterol and budesonide in patients with mild to moderate asthma.



\




Airsupra is a first-in-class, pressurised metered-dose inhaler (pMDI), fixed-dose combination rescue medication containing albuterol, a short-acting beta2-agonist (SABA), and budesonide, an anti-inflammatory inhaled corticosteroid (ICS) in the US. It is being developed by AstraZeneca and Avillion.

Bradley E. Chipps, Past President of the American College of Allergy, Asthma & Immunology and Medical Director of Capital Allergy & Respiratory Disease Center in Sacramento, US, said: “People with asthma are at risk of severe exacerbations regardless of their disease severity or level of control. Current albuterol rescue inhalers alleviate acute symptoms, but do not treat the underlying inflammation in asthma. The approval of Airsupra means that for the first time, adults with asthma in the US have a rescue treatment to manage both their symptoms and the inflammatory nature of their disease.”

Mene Pangalos, Executive Vice President, BioPharmaceuticals R&D, AstraZeneca, said: “With patients experiencing more than 10 million asthma exacerbations each year in the US and uncontrolled asthma expected to cost the US economy billions of dollars in direct medical costs alone over the next 20 years, today’s positive decision is good news for those adults with asthma who make up more than 80% of asthma patients in the US. Physicians will be able to offer their patients Airsupra, an important new rescue treatment that reduces the risk of asthma exacerbations.”

Asthma is a chronic, inflammatory respiratory disease with variable symptoms that affects as many as 262 million people worldwide.3 In the US over 21 million adults have asthma, representing more than 80% of the total number of people with asthma.4 Adults have 8.5 million exacerbations each year in the US.4 Uncontrolled asthma will cost the US economy an estimated $300 billion (in 2018 dollar values) in the next 20 years in direct medical costs alone.5


The safety and tolerability of Airsupra in both trials were consistent with the known profiles of the components,1,2 with the most common adverse events including headache, oral candidiasis, cough and dysphonia
