Incyte Announces Acceptance of NDA for Parsaclisib for Refractory Non-Hodgkin Lymphomas

 

 

 

Incyte (Nasdaq:INCY)  announced,  that the U.S. Food and Drug Administration (FDA) has accepted its New Drug Application (NDA) for parsaclisib, an investigational novel potent, highly selective, next-generation oral inhibitor of phosphatidylinositol 3-kinase delta (PI3Kδ), for the treatment of patients with relapsed or refractory follicular lymphoma (FL), marginal zone lymphoma (MZL) and mantle cell lymphoma (MCL).

The submission is based on data from several Phase 2 studies (CITADEL-203, -204 and -205) evaluating parsaclisib as a treatment for relapsed or refractory non-Hodgkin lymphomas (NHLs) (FL, MZL and MCL). Parsaclisib was generally well-tolerated in all studies with a manageable safety profile.

“Non-Hodgkin lymphomas are some of the most common cancers in the United States, and the FDA’s acceptance of this NDA represents an important milestone for Incyte and for NHL patients who have not responded to or who have progressed on initial therapies,” said Peter Langmuir, M.D., Group Vice President, Oncology Targeted Therapies, Incyte. “We look forward to working with the FDA to bring this innovative therapy to patients who may benefit.”

Parsaclisib has been granted Priority Review by the FDA for the treatment of adult patients with relapsed or refractory MZL who have received at least one prior anti-CD20-based regimen and for the treatment of adult patients with MCL who have received at least one prior therapy. The FDA grants Priority Review to medicines that, if approved, would be significant improvements in the safety or effectiveness of the treatment, diagnosis or prevention of serious conditions when compared to standard applications. This designation shortens the review period by four months as compared to Standard Review so the Prescription Drug User Fee Act (PDUFA) target action date for these indications is April 30, 2022. The NDA for use of parsaclisib in adult patients with relapsed or refractory follicular lymphoma (FL) who have received at least two prior systemic therapies will have a Standard Review and a PDUFA target action date of August 30, 2022.

Confirmatory phase 3 studies are in preparation for parsaclisib in patients with MCL (CITADEL-310) and relapsed or refractory FL and MZL (CITADEL-302).

Amylyx Pharmaceuticals Submits New Drug Application (NDA) for AMX0035 for the Treatment of ALS

 

Sodium phenylbutyrate

          

 

 

Taurursodiol

 

 

 

Amylyx Pharmaceuticals, Inc.  announced that, it has submitted a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) for AMX0035 (sodium phenylbutyrate (PB) and taurursodiol (TURSO; also known as ursodoxicoltaurine)) for the treatment of amyotrophic lateral sclerosis (ALS).

“We are excited to share with the ALS community the exciting milestone that we have submitted our NDA to the FDA for review,” said Justin Klee, Co-CEO, Director and Co-Founder of Amylyx. Joshua Cohen, Co-CEO, Chairman and Co-Founder of Amylyx added, “Our team has worked and continues to work around the clock as we know time is of the essence for people living with ALS and their families. We will continue to keep the community closely updated on our progress.”

“We will continue to work closely with the FDA throughout the review process to move AMX0035 toward a potential regulatory approval as quickly and efficiently as possible,” said Tammy Sarnelli, Global Head of Regulatory Affairs of Amylyx. “We are so inspired by the people who participated in CENTAUR, the trial investigators, the ALS community and our partners and team, and we will continue to work tirelessly on behalf of you all.”

The NDA submission to the FDA is based on data from the CENTAUR trial, a placebo-controlled study evaluating 137 people with ALS. In this study, participants receiving AMX0035 had statistically significant slowing of functional decline at the end of the 6-month randomized phase as measured by the Revised ALS Functional Rating Scale (ALSFRS-R), the most commonly used scale in clinics worldwide to measure function in ALS. In an interim survival analysis conducted in all randomized participants from CENTAUR who were followed for up to three years, which included participants who continued to receive AMX0035 in an open-label extension phase during the follow-up period, participants who started on AMX0035 during the placebo-controlled phase of CENTAUR showed a 44% lower risk of death compared to those who started on placebo during the placebo-controlled phase (HR 0.56; 95% CI, 0.34-0.92). Median survival duration through the open-label long-term follow-up phase was 25.0 months (95% CI, 19.0-33.6 months) in the group that started on AMX0035 and 18.5 months (95% CI, 13.5-23.2 months) in the group that started on placebo, a 6.5-month difference. Overall, reported rates of adverse events and discontinuations were substantially similar between AMX0035 and placebo groups during the 24-week randomized phase; however, gastrointestinal events occurred with greater frequency (≥2%) in the AMX0035 group. Detailed data from CENTAUR is published in the New England Journal of Medicine (NEJM) and Muscle and Nerve.

“This submission brings hope to people living with ALS and their families and caregivers,” said Merit Cudkowicz, M.D., co-principal investigator of the CENTAUR trial and co-founder of the Northeast ALS Consortium, Director of the Healey & AMG Center for ALS and Chair of Neurology at Massachusetts General Hospital and the Julieanne Dorn Professor of Neurology at Harvard Medical School. “We are honored to have led the collaboration between the Healey & AMG Center for ALS, ALS Finding a Cure, the ALS Association, and NEALS that made the CENTAUR trial a reality, the efforts and results of which made this NDA submission possible.”

“For people living with ALS and their physicians, this is a significant development offering hope of a potential new treatment option that has been shown to slow ALS disease progression and extend the time families that face this life-threatening disease have together,” said Sabrina Paganoni, M.D., Ph.D., principal investigator of the CENTAUR trial, investigator at the Healey & AMG Center for ALS at Massachusetts General Hospital and Assistant Professor of PM&R at Harvard Medical School and Spaulding Rehabilitation Hospital.

As previously reported, Amylyx filed a New Drug Submission (NDS) for AMX0035 for the treatment of ALS with Health Canada in June 2021. Amylyx also intends to submit a Marketing Authorization Application (MAA) for AMX0035 to the European Medicines Agency’s (EMA) Committee for Medicinal Products for Human Use (CHMP) by approximately the end of 2021 and to initiate a global Phase 3 clinical trial with sites in Europe and the United States in the fourth quarter of 2021. The Phase 3 PHOENIX trial of AMX0035 for the treatment of people with ALS will assess the safety and efficacy of AMX0035 in an international population of approximately 600 participants and build upon findings from the CENTAUR trial. Amylyx is currently exploring the possibility of an Expanded Access Program (EAP) in the United States. If implemented, the EAP would run in parallel with the ongoing Phase 3 PHOENIX trial and marketing application reviews. Further information about the EAP is expected in the fourth quarter of 2021.

FDA Grants Tentative Approval for Liquidia’s Yutrepia (treprostinil) Inhalation Powder

 In continuation of my update on treprostinil

 

Liquidia Corporation  announced that, the U.S. Food and Drug Administration (FDA) has granted tentative approval for Yutrepia™ (treprostinil) inhalation powder, previously referred to as LIQ861. Yutrepia is indicated for the treatment of pulmonary arterial hypertension (PAH) to improve exercise ability in adult patients with New York Heart Association (NYHA) Functional Class II-III symptoms. Tentative approval indicates that Yutrepia has met all regulatory standards for quality, safety and efficacy required for approval in the United States.

 

Dr. Tushar Shah, Chief Medical Officer of Liquidia, said: “We would like to take the opportunity to thank the patients and investigators who participated in the clinical development of Yutrepia. The tentative approval for Yutrepia is another step toward providing an important option for patients with PAH in the U.S. We believe Yutrepia can improve the limitations of current nebulized therapies by allowing the administration of an expanded dose range of inhaled treprostinil using a proven, convenient, palm-sized device.”

The addressable market for inhaled treprostinil is significant and expected to grow. In 2020, United Therapeutics reported that its nebulized formulation of treprostinil indicated for PAH achieved sales of more than $480 million. The attributes of Yutrepia including ease-of-use, convenience, direct lung delivery, and higher dosage range may not only make Yutrepia a preference to nebulized therapy, but also an alternative to oral treatments, and possibly a treatment option to delay the use of parenteral therapies in PAH. There may also be future expansion opportunities for inhaled treprostinil into additional indications.

Damian deGoa, Chief Executive Officer of Liquidia added: “This is a significant milestone for Liquidia. We are really proud of our team. Not only does the tentative approval establish the safety and efficacy of Yutrepia for PAH patients but, in the process, we have validated our proprietary PRINT® technology to engineer discrete drug particles with uniform composition, size, and shape. There is more work to be done. We will now focus our efforts on pre-commercial launch activities and the growing market opportunity for Yutrepia in PAH and potential new indications.”

Due to a regulatory stay pursuant to the Drug Price Competition and Patent Term Restoration Act (Hatch-Waxman Act), Yutrepia cannot yet be marketed in the United States. In June 2020, United Therapeutics filed a lawsuit against Liquidia for alleged infringement of three patents related to Tyvaso®. As a result, the FDA cannot give final approval of Yutrepia until the expiration of the regulatory stay on October 27, 2022, or earlier resolution or settlement of the ongoing litigation.

About Yutrepia™(treprostinil) inhalation powder
Yutrepia is an investigational, inhaled dry powder formulation of treprostinil delivered through a proven, convenient, palm-sized device. On November 5, 2021, the FDA issued a tentative approval for Yutrepia, which is indicated for the treatment of pulmonary arterial hypertension (PAH) to improve exercise ability in adult patients with New York Heart Association (NYHA) Functional Class II-III symptoms. Yutrepia was designed using Liquidia’s PRINT® technology, which enables the development of drug particles that are precise and uniform in size, shape, and composition, and that are engineered for optimal deposition in the lung following oral inhalation. Liquidia has completed INSPIRE, or Investigation of the Safety and Pharmacology of Dry Powder Inhalation of Treprostinil, an open-label, multi-center phase 3 clinical study of Yutrepia in patients diagnosed with PAH who are naïve to inhaled treprostinil or who are transitioning from Tyvaso (nebulized treprostinil). Yutrepia was previously referred to as LIQ861 in investigational studies.

Submission of HTX-019 (aprepitant) NDA for the Prevention of Postoperative Nausea and Vomiting to FDA

 

 

 

 

Heron Therapeutics, Inc.  announced the submission of its New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) for HTX-019 (aprepitant) injectable emulsion for the prevention of postoperative nausea and vomiting (PONV) in adults. HTX-019 is a proprietary intravenous (IV) formulation of aprepitant, a substance P/neurokinin-1 (NK₁) receptor antagonist (RA) that is approved for PONV prevention.

The NDA filing includes data demonstrating the bioequivalence of HTX-019 32 mg as a 30-second IV injection to oral aprepitant 40 mg, supporting its efficacy for the prevention of PONV. Results also showed HTX-019 was well-tolerated with a similar safety profile compared to oral aprepitant. Because HTX-019 is administered as an IV injection, it provides convenient, rapid, consistent, and reliable exposure in all patients and overcomes the need to take the oral formulation 1 to 3 hours before anesthesia. The HTX-019 injectable emulsion formulation intended for PONV prevention is identical to the approved CINVANTI^® (aprepitant) injectable emulsion formulation for prevention of chemotherapy-induced nausea and vomiting (CINV).

Despite advances in postoperative care, nausea and vomiting has remained a challenge for many patients undergoing surgery. There are approximately 65 million diagnostic and surgical procedures at risk of resulting in PONV in the U.S. each year. More than half of these patients are at moderate to high risk of developing PONV. Recent data has also shown that PONV can lead to increases in medical costs and delays in discharge and recovery following procedures. Aprepitant is the first and only NK₁ RA to be approved for prevention of PONV based on showing superiority to ondansetron, the current standard of care.

"In a recent Cochrane Meta-Analysis, aprepitant was found to be the most effective agent for PONV prevention with activity similar to two-drug combinations. In fact, the use of oral aprepitant has grown by almost 80% in the past three years without any promotional efforts. Our IV formulation is designed to directly deliver the active form of the drug, aprepitant, to patients over 30 seconds so it can take effect much more quickly than when taken orally," said Barry Quart, Pharm.D., Chairman and Chief Executive Officer of Heron. "The HTX-019 NDA was filed with the same FDA division that previously approved CINVANTI without delays."

"There remains an important unmet need for effective and convenient products for PONV prevention," said Ashraf Habib, MBBCh, MSc, MHSc, FRCA, Chief, Division of Women's Anesthesia at Duke University Hospital. "If approved, this innovative IV formulation of aprepitant, with rapid achievement of therapeutic drug levels, will enable physicians to provide patients with a well-established agent that effectively prevents nausea and vomiting after surgery, using a route of administration that fits well in the perioperative workflow."

About HTX-019 for PONV

HTX-019 is an IV injectable emulsion formulation designed to directly deliver aprepitant, the active ingredient in EMEND^® (aprepitant) capsules, which is the only substance P/neurokinin-1 receptor antagonist to be approved in the U.S. for the prevention of postoperative nausea and vomiting (PONV) in adults. The FDA-approved dose of oral EMEND is 40 mg for PONV prevention, which is given within 3 hours prior to induction of anesthesia for surgery. In a Phase 1 clinical trial, 32 mg of HTX-019 as a 30-second IV injection was demonstrated to be bioequivalent to oral aprepitant 40 mg. The NDA for HTX-019 for PONV was submitted in November 2021.

Obseva Announces U.S. FDA Acceptance of New Drug Application for Linzagolix

Obseva SA   announced   the New Drug Application (NDA) for linzagolix for the management of heavy menstrual bleeding associated with uterine fibroids in premenopausal women has been accepted for review by the United States Food and Drug Administration (FDA). The submission is based on data from the two Phase 3 PRIMROSE trials. Linzagolix has a differentiated profile and if approved, would be the first and only GnRH receptor antagonist with flexible dosing options for uterine fibroids, including a low dose option to address the needs of women who cannot or do not want to take hormones.1,4 The FDA set a target action date of September 13, 2022 for this NDA under the Prescription Drug User Fee Act (PDUFA).

“Today marks an important milestone not only in the linzagolix clinical development process, but for Obseva as a company, and most importantly, the millions of women living with uterine fibroids throughout the US. Linzagolix is a significant innovation in the field of women’s health – an area that is consistently underinvested in – and we are incredibly excited about the potential of bringing this important treatment to market” said Brian O’Callaghan, CEO of Obseva. “We are encouraged by our positive Phase 3 PRIMROSE results. If approved, we believe linzagolix will address a significant unmet need in offering a more individualized treatment option for a broader range of women.”

The Phase 3 PRIMROSE trials of linzagolix (PRIMROSE 1: US; n=574 and PRIMROSE 2: Europe and US; n=535) investigated the efficacy and safety of two dosing regimens, 100mg once daily and 200mg once daily, alone or in combination with hormonal ABT (1 mg estradiol and 0.5 mg norethisterone acetate) for the treatment of heavy menstrual bleeding associated with uterine fibroids. The NDA submission comprises positive 24-week treatment results from both studies, as well as supportive results from Week 52 and the 76-week post-treatment follow-up.

“Uterine fibroids can have a devastating impact on women’s day-to-day life. With its unique dosing options, linzagolix has the potential to significantly advance medical options for women,” stated Elizabeth Garner, MD, MPH, Chief Medical Officer of Obseva. “A dosing option without hormonal ABT would be welcomed by the significant number of women who either have contraindications to or a personal preference to avoid the use of estrogen-based therapies, while also providing a dosing option for women in whom hormonal ABT is indicated.”

The linzagolix marketing authorization application (MAA) was validated by the European Medicine Agency (EMA) with an approval recommendation from the Committee for Medicinal Products for Human Use (CHMP) expected in Q4 2021. Obseva announced previously that the company has entered into a partnership with Syneos Health to support commercialization of linzagolix in the US and EU.

New Drug Application of Plinabulin (Response Letter from the FDA) for Prevention of Chemotherapy-Induced Neutropenia (CIN)...

 BeyondSpring Pharmaceuticals  announced the receipt of  a Complete Response Letter (CRL) from the U.S. Food and Drug Administration (FDA) for the New Drug Application (NDA) seeking approval of plinabulin in combination with granulocyte colony-stimulating factor (G-CSF) for the prevention of chemotherapy-induced neutropenia (CIN). The FDA issued the CRL to indicate that they have completed their review of the application and have determined that it cannot be approved in its present form.

 

The FDA’s CRL indicated that the results of the single registrational trial (106 Phase 3) was not sufficiently robust to demonstrate benefit and that a second well controlled trial would be required to satisfy the substantial evidence requirement to support the CIN indication.

“BeyondSpring strongly believes that plinabulin in combination with G-CSF has significant potential to raise the standard of care in CIN, a devastating side effect of chemotherapy,” said Dr. Lan Huang, BeyondSpring’s co-founder, chief executive officer and chairwoman. “The Company plans to request a meeting with the FDA and remains committed to its goal of bringing plinabulin to cancer patients in need globally.”

BeyondSpring remains confident in the efficacy and safety data for plinabulin in combination with G-CSF for the prevention of CIN. The Company expects to work closely with the FDA to consider the possible future clinical pathway for CIN, which may include a second study.

Plinabulin is the first drug candidate submitted for FDA approval that has the potential to work in the critical first week of chemotherapy treatment before G-CSF is effective, to prevent the onset and improve clinical outcomes of CIN.

Plinabulin, BeyondSpring’s lead asset, is a selective immunomodulating microtubule-binding agent (SIMBA), which is a potent antigen presenting cell (APC) inducer. It is a novel, intravenous infused, patent-protected, NDA-stage asset for CIN prevention and a Phase 3 anti-cancer candidate for non-small cell lung cancer (NSCLC) with recently released positive topline data. Plinabulin triggers the release of the immune defense protein, GEF-H1, which leads to two distinct effects: first is a durable anticancer benefit due to the maturation of dendritic cells resulting in the activation of tumor antigen-specific T-cells to target cancer cells, and the second is early-onset of action in CIN prevention after chemotherapy by boosting the number of hematopoietic stem/progenitor cells (HSPCs). Plinabulin received Breakthrough Therapy designation and priority review from both U.S. and China FDA for the CIN prevention indication. As a “pipeline in a drug,” plinabulin is being broadly studied in combination with various immuno-oncology agents that could boost the effects of the PD-1/PD-L1 antibodies and re-sensitize PD-1/PD-L1 antibody-resistant patients.

FDA Approves Cytalux (pafolacianine) Injection for Identification of Ovarian Cancer During Surgery

 

Target Laboratories, Inc.,  announced the U.S. Food and Drug Administration (FDA)  approval of Cytalux for adult patients with ovarian cancer as an adjunct for intraoperative identification of malignant lesions. Cytalux is the first targeted fluorescent imaging agent that illuminates ovarian cancer intraoperatively, enabling the detection of more cancer for removal. Cytalux, administered by standard IV in as little as one hour before surgery, binds to folate receptors that are overexpressed in most epithelial ovarian cancersi and illuminates intraoperatively under near-infrared light.

"Complete removal of all malignant tissue is the goal of ovarian cancer surgery, however identifying all lesions can be challenging," said Dr. Janos L. Tanyi, MD, PhD, Associate Professor of Obstetrics and Gynecology, University of Pennsylvania Perelman School of Medicine and Investigator on the Phase 2 and 3 studies. "In the Phase 3 study, additional cancer was detected in 27% of patients, showing great promise in the ability of Cytalux to help surgeons identify malignant lesions that may otherwise be missed during surgery."

Ovarian cancer is the number one cause of gynecologic cancer death in the United Statesii. Cytoreductive surgery is a well-established treatment for ovarian cancer, however, a study showed that among patients reported to have undergone optimal cytoreduction, 40% were found to have measurable disease on 30-day postoperative imagingiii. Cytalux serves as an adjunctive tool for surgeons to identify additional malignant ovarian cancer lesions that may have been missed by standard visual inspection and palpation, increasing the detection of more cancer during surgery.

Adverse reactions consisting of nausea, vomiting, abdominal pain, flushing, indigestion, chest discomfort, and itching were reported during the administration of Cytalux (see additional Important Safety Information below).

"This FDA approval is a significant milestone towards achieving On Target's mission to make cancer visible during surgery so it can be removed more completely," said Chris Barys, President and Chief Executive Officer of On Target Laboratories. "We are excited about the potential impact Cytalux can have for patients in their fight against ovarian cancer. Our goal is to make Cytalux a standard of care for ovarian cancer surgery and we look forward to exploring the use of our technology for patients suffering from other cancers."

Cytalux received Priority Review and both Fast Track and Orphan designations from the FDA. Additionally, Cytalux is being investigated in cancer of the lung in a Phase 3 trial under Fast Track designation.

To date, there have been limited ways for surgeons to confidently assess the location and full extent of cancerous tissue while operating. On Target Laboratories' targeted fluorescent imaging agents are comprised of a near-infrared dye and a targeting molecule, or ligand, that binds to receptors overexpressed on cancer cells. The imaging agents illuminate the cancerous tissue, which may enable surgeons to detect more cancer that otherwise may have been left behind.

On Target's first novel compound, Cytalux, targets folate receptors commonly found on many cancers, such as ovarian cancer. A single dose of the agent is administered via intravenous infusion prior to surgery to help the surgeon identify additional malignant tissue during the operation using a near-infrared imaging system.
