The use of interleukin-2 (IL-2)-directed therapies has been associated with systemic toxicities, regulatory T cell (Treg) activation and limited efficacy so far. Researchers from Regeneron Pharmaceuticals Inc. have described REGN-10597 (PD1-IL2Ra-IL2), a programmed cell death protein 1 (PD-1)-targeted, receptor-masked IL-2 immunocytokine.
Regeneron Pharmaceuticals Inc. has patented rapamycin analogues acting as peptidyl-prolyl cis-trans isomerase FKBP1A (FKBP12; Rotamase) ligands reported to be useful for the treatment of Alzheimer’s disease, graft-vs.-host disease, cancer, sarcopenia and more.
The nearer-looming threat of a biosimilar from Amgen Inc. to heavyweight Regeneron Pharmaceuticals Inc.’s age-related macular degeneration (AMD) VEGF therapy, Eylea (aflibercept), along with other issues, pressured shares of the latter (NASDAQ:REGN) since reporting third-quarter earnings Oct 31. But Wall Street pundits are not altogether aligned on how serious the scenario might be. After the earnings update, Regeneron’s stock fell 12%, from $925 to $819.96, and closed Nov. 1 at $843.60, up $5.40.
Regeneron Pharmaceuticals Inc. has patented new 17-β-hydroxysteroid dehydrogenase 13 (HSD17B13; 17-β-HSD-13) inhibitors reported to be useful for the treatment of liver diseases.
Five months after getting a complete response letter from the U.S. FDA, Regeneron Pharmaceuticals Inc. has landed conditional European marketing approval for odronextamab, a bispecific antibody for treating lymphoma. Now named Ordspono, the approval is for treating adult patients with relapsed or refractory follicular lymphoma or diffuse large B-cell lymphoma, after two or more lines of therapy. The European Commission also approved Merck & Co. Inc.’s Winrevair (sotatercept) for pulmonary arterial hypertension and ARS Pharmaceuticals Inc.'s Eurneffy (inhaled epinephrine) for anaphylaxis.
Regeneron Pharmaceuticals Inc. suffered an unsurprising hitch in the form of a complete response letter (CRL) related to linvoseltamab, a bispecific antibody designed to bridge B-cell maturation antigen on multiple myeloma cells containing CD3-expressing T cells, for relapsed/refractory multiple myeloma.
The U.S. FDA granted approval of Verona Pharma plc’s ensifentrine on its PDUFA date of June 26, giving the chronic obstructive pulmonary disease (COPD) community its first new mechanistic option in a decade. The drug, branded Ohtuvayre, is also the first inhaled nonsteroidal therapy to treat a respiratory disease that combines both a bronchodilator and anti-inflammatory mechanism into one molecule. It is indicated for the maintenance treatment of COPD, which Verona said allows for broad use.
Transmembrane serine protease 6 (TMPRSS6) is a negative regulator of hepcidin, which is the main iron homeostasis-regulating hormone. Regeneron Pharmaceuticals Inc. has recently presented preclinical data for the monoclonal antibody targeting TMPRSS6, REGN-7999, which is being developed for the treatment of iron overload.
In an indication with few treatment options for patients who are running out of time, Replimune Group Inc. revealed positive top-line results of its lead candidate, RP-1 (vusolimogene oderparepvec), in anti-PD-1-failed melanoma. Data from the phase I/II Ignyte study of RP-1 plus Opdivo (nivolumab, Bristol Myers Squibb Co.) showed the treatment hit the primary endpoint with a 12-month overall response rate of 33.6% and a median duration of response of more than 35 months.
Celltrion Inc., of Incheon, South Korea, gained MFDS clearance of Eydenzelt (CT-P42) as a biosimilar referencing Regeneron Pharmaceuticals Inc./Bayer AG’s Eylea (aflibercept) on May 30. The news comes on the heels of the U.S. FDA approving the first Eylea interchangeable biosimilars on May 20.
