Biotech Stock Roundup: NKTR Plunges on Deal Termination, REGN Offers Update & More

Read MoreHide Full Article

The biotech sector has been in focus in the past week with some important pipeline and regulatory updates. Acquisition news has also grabbed the spotlight in the week.

Recap of the Week’s Most Important Stories:

Nektar Plunges on Deal Termination:  Shares of Nektar Therapeutics (NKTR - Free Report) plunged significantly after the company and partner Bristol Myers Squibb (BMY - Free Report) announced the joint decision to end the global clinical development program for bempegaldesleukin (BEMPEG) in combination with the latter’s blockbuster immuno-oncology drug Opdivo (nivolumab).  The decision was based on disappointing results from pre-planned analyses of two late-stage clinical studies of bempegaldesleukin in combination with Opdivo in renal cell carcinoma (RCC) and bladder cancer.  Nektar and Bristol Myers collaborated in 2018 to evaluate the combination. The companies have now decided to discontinue these studies and all others in the program.

The pre-planned analysis of phase III PIVOT-09 study evaluating BEMPEG plus Opdivo in patients with previously untreated advanced RCC demonstrated that the combination regimen failed to meet the pre-specified boundary for statistical significance for objective response rate (ORR) compared to a tyrosine kinase inhibitor (TKI) therapy in the comparator-arm of the study. The final analysis of the phase II PIVOT-10 study showed that the BEMPEG and Opdivo doublet therapy did not reach an efficacy threshold for ORR to support continuing evaluation of the regimen in patients with locally advanced or metastatic urothelial cancer or bladder cancer.

Updates From Regeneron: Regeneron Pharmaceuticals, Inc. (REGN - Free Report) announced that the FDA has extended the review of the biologics license application (BLA) for antibody cocktail REGEN-COV (casirivimab and imdevimab) by three months.

The regulatory body extended the review due to ongoing discussions on pre-exposure prophylactic use for which Regeneron has submitted additional data from its completed prophylaxis trial that the FDA has accepted for review. The agency considers the submission of these additional data to be a major amendment to the BLA and has extended the target action date to Jul 13, 2022. On a positive note, the FDA has not requested any new studies to complete its review of the current BLA at this time.

Regeneron also announced that it will acquire clinical-stage biopharmaceutical Checkmate Pharmaceuticals, Inc.  for $10.50 per share or $250 million, which fueled the share price of the latter. The acquisition will add investigational candidate vidutolimod to its pipeline. Vidutolimod is a potential best-in-class TLR9 agonist, with demonstrated clinical responses observed in PD-1 refractory melanoma as monotherapy.   The transaction is expected to close in mid-2022. The acquisition should strengthen Regeneron’s portfolio of diverse and combinable immuno-oncology candidates. 

Regeneron currently carries a Zacks Rank #3 (Hold).  You can see the complete list of today’s Zacks #1 Rank (Strong Buy) stocks here.

Axsome Soars on Update: Shares of Axsome Therapeutics, Inc. (AXSM - Free Report) surged after the company announced that it has received and agreed to Postmarketing Requirements/Commitments proposed by the FDA with respect to the new drug application (NDA) for its investigational candidate AXS-05. The NDA is seeking approval of the candidate for the treatment of major depressive disorders (MDD). Consequently, Axsome anticipates the potential approval of the candidate in the second quarter of 2022. AXS-05 (dextromethorphan-bupropion) is Axsome’s novel, oral, investigational NMDA receptor antagonist with multimodal activity being developed for MDD, Alzheimer’s disease agitation and smoking cessation.
