Elevar Therapeutics Announces FDA Acceptance for Review of New Drug Application for Lirafugratinib as Second-line Cholangiocarcinoma Treatment

Elevar Therapeutics, Inc., a majority-owned subsidiary of HLB Co., Ltd. and a fully integrated biopharmaceutical company dedicated to elevating treatment experiences and outcomes for patients who have limited or inadequate therapeutic options, today announced that the U.S. Food and Drug Administration (FDA) has completed its filing review of the New Drug Application (NDA) for lirafugratinib, an investigational therapy, for the treatment of patients with cholangiocarcinoma (CCA) with FGFR2 fusions or rearrangements who have received prior therapy. The FDA determined that the NDA is sufficiently complete to permit a substantive review and granted Priority Review, with a Prescription Drug User Fee Act (PDUFA) target action date of September 27, 2026.

• With Priority Review designation, FDA set a Sept. 27 PDUFA date for approval decision
• Lirafugratinib achieved a 46.5% ORR, in CCA patients with FGFR2 fusion and rearrangement

Priority Review designations are given to applications for medicines that, if approved, would lead to “significant improvements in the safety or effectiveness of the treatment” of a serious condition, according to the FDA. The Priority Review designation of the lirafugratinib NDA was supported by positive clinical data from the Phase 1/2 ReFocus trial (NCT04526106), which demonstrated a confirmed objective response rate (ORR) of 46.5% in the patients with the proposed indication. Its safety profile in the clinical data has been shown to be predictable and manageable through dose adjustments.

“Lirafugratinib has established a compelling clinical profile that differentiates it from existing treatment options,” said Dong-Gun Kim, chief executive officer of Elevar. “We are very pleased with the FDA’s priority review designation and focused on advancing the review process efficiently to bring this therapy to patients as quickly as possible.”

CCA, also known as bile duct cancer, is rare, with about 8,000 people in the U.S. diagnosed each year, according to the American Cancer Society.

Elevar Therapeutics continues to evaluate lirafugratinib in ongoing clinical development programs, including studies in other FGFR2-altered solid tumors. Any future indications will be subject to regulatory review and approval.

About Lirafugratinib

Lirafugratinib (RLY-4008) is a potent, selective, and oral small molecule inhibitor of FGFR2, a receptor tyrosine kinase that is frequently altered in certain cancers. FGFR2 is one of four members of the FGFR family, a set of closely related proteins with highly similar protein sequences and properties. Preclinically, lirafugratinib demonstrated FGFR2-dependent killing in cancer cell lines and induced regression in in vivo models with minimal inhibition of other targets, including other members of the FGFR family. In addition, lirafugratinib demonstrated strong activity against known clinical on-target resistance mutations in vitro and in vivo preclinical models. Lirafugratinib is currently being evaluated in a clinical trial to enroll additional patients with previously treated, advanced or metastatic solid tumors other than CCA harboring FGFR2 fusion or rearrangement, who have not been treated with prior FGFR inhibitors.

Aldeyra Therapeutics Announces FDA Acceptance for Review of Reproxalap New Drug Application for the Treatment of Dry Eye Disease

Aldeyra Therapeutics, Inc. (Nasdaq: ALDX) (Aldeyra)  announced   the U.S. Food and Drug Administration (FDA)   acceptance the  review of the resubmitted New Drug Application (NDA) for topical ocular reproxalap, a first-in-class investigational new drug candidate, for the treatment of the signs and symptoms of dry eye disease. The FDA assigned a Prescription Drug User Fee Act (PDUFA) target action date of December 16, 2025.

“Based on the FDA’s requirement for an additional clinical trial demonstrating the efficacy of reproxalap in treating the symptoms of dry eye disease, and per agreement with the FDA, the NDA resubmission contained a single clinical trial that achieved the primary endpoint of reducing ocular discomfort relative to the vehicle control,” stated Todd C. Brady, M.D., Ph.D., President and Chief Executive Officer of Aldeyra. “We look forward to a productive dialog with the FDA during the NDA review of reproxalap, which, to our knowledge, remains the only dry eye disease investigational therapy to have demonstrated acute activity in reducing ocular discomfort and redness in pivotal trials simulating the disease flares that are likely the most bothersome aspects of dry eye disease.”

About Reproxalap

Reproxalap is an investigational new drug candidate in development for the treatment of dry eye disease and allergic conjunctivitis, two of the largest markets in ophthalmology. Reproxalap is a first-in-class small-molecule modulator of RASP, which are elevated in ocular and systemic inflammatory diseases.

FDA Grants Priority Review for Daiichi Sankyo’s New Drug Application for CSF1R Inhibitor Pexidartinib for Treatment of Patients with TGCT, a Rare, Debilitating Tumor

  

Daiichi Sankyo Company, Limited (hereafter, Daiichi Sankyo) announced that the U.S. Food and Drug Administration (FDA) has accepted a New Drug Application (NDA) and granted Priority Review for pexidartinib for the treatment of adult patients with symptomatic tenosynovial giant cell tumor (TGCT), which is associated with severe morbidity or functional limitations, and which is not amenable to improvement with surgery.  TGCT, also referred to as pigmented villonodular synovitis (PVNS) or giant cell tumor of the tendon sheath (GCT-TS), is a non-malignant tumor of the joint or tendon sheath, which can be locally aggressive and debilitating in some patients. There are no currently approved systemic therapies for TGCT.

A Priority Review designation is granted by the FDA to drugs 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. Under Priority Review, the FDA aims to take action on an application within six months, as compared to ten months under standard review. The FDA has designated August 3, 2019 as the PDUFA Action date for this application. 

On January 31, 2019, the American Society of Clinical Oncology (ASCO) recognized “Progress in Treating Rare Cancers” as the “Advance of the Year”, and selected pexidartinib as one of five significant advancements in rare disease treatment, calling it the first promising investigational therapy for TGCT.

The NDA is based on results of the pivotal phase 3 ENLIVEN study of oral pexidartinib, the first placebo-controlled study of a systemic investigational therapy in patients with TGCT. Results of the phase 3 ENLIVEN study were presented during an oral presentation at the 2018 American Society of Clinical Oncology (ASCO) Annual Meeting.

“We are pleased to announce that the FDA has accepted our application for pexidartinib with Priority Review designation, potentially bringing a treatment option to patients for whom there is no approved therapy,” said Dale Shuster, Ph.D., Executive Director, Global Oncology R&D, Daiichi Sankyo. “Current treatment options for TGCT are largely limited to surgery, but for some patients the disease is debilitating and not amenable to improvement with surgery. We are committed to working with the FDA to potentially bring pexidartinib to carefully-selected patients as soon as possible.”

“We are excited about the first-in-class potential of pexidartinib, another targeted therapy discovered by Plexxikon,” said Gideon Bollag, Ph.D., Chief Executive Officer of Plexxikon Inc., Daiichi Sankyo’s small molecule structure-guided R&D center in Berkeley, CA and a member of the Daiichi Sankyo Group. “Our drug discovery process uses structural data and a specialized scaffold-like screening library to identify and optimize novel drug candidates.”

ENLIVEN is a pivotal, double-blind, randomized, global multi-center phase 3 study that evaluated pexidartinib in patients with symptomatic advanced TGCT for whom surgical removal of the tumor would be associated with potentially worsening functional limitation or severe morbidity. The first part of the study, the double-blind phase, enrolled 120 patients who were randomized (1:1) to receive either pexidartinib or placebo at 1000 mg/d for 2 weeks followed by 800 mg/d for 22 weeks in order to evaluate the efficacy and safety of pexidartinib versus placebo. The primary endpoint of the study was the percentage of patients achieving a complete or partial response after 24 weeks of treatment (Week 25), as assessed with centrally-read MRI scans using RECIST 1.1 criteria. Key secondary endpoints included range of motion, response by tumor volume score, PROMIS physical function, stiffness and measures of pain reduction.

The ENLIVEN study met its primary endpoint of overall response rate. In the ENLIVEN study, hepatic toxicities were more frequent with pexidartinib versus placebo (AST or ALT ≥3X ULN: 33 percent, total bilirubin ≥2X ULN: 5 percent, N=61). Eight patients discontinued pexidartinib due to hepatic adverse events (AEs); four were serious nonfatal AEs with increased bilirubin, one lasting ~7 months. In non-TGCT development studies using pexidartinib, two severe liver toxicity cases (one required liver transplant, one was associated with death) were observed.
