Gastric inhibitory polypeptide receptor (GIPR) antagonists potentially useful for the treatment of type 2 diabetes and obesity have been disclosed in a Pfizer Inc. patent.

Camurus AB received a complete response letter (CRL) from the U.S. FDA for CAM-2029 (octreotide), its extended-release injection for acromegaly, due to “facility-related deficiencies” identified during a cGMP inspection of a third-party manufacturer. The Lund, Sweden-based company noted that the CRL did not indicate any concerns related to clinical efficacy or safety. Camurus will work with the FDA and the third-party manufacturer to address the concerns, said Fredrik Tiberg, president and CEO.
The U.S. FDA has approved the second hemophilia drug in nearly six months from Pfizer Inc. This one, Hympavzi (marstacimab), is for preventing or reducing bleeding in those age 12 and older with hemophilia A and B. Hympavzi heralds a couple of market boundary breakers: it’s the first and only anti-tissue factor pathway inhibitor approved in the U.S. for hemophilia A or B and the first hemophilia medicine approved in the U.S. to be administered using a pre-filled, auto-injector pen.
Genentech Inc. didn’t need to wait until Thanksgiving for the U.S. FDA to make up its mind. More than a month ahead of its PDUFA date, the agency approved the firm’s first-line breast cancer treatment, Itovebi (inavolisib), providing the oral therapy a place with other niched therapies from Astrazeneca plc and Novartis AG. Itovebi is to be combined with Pfizer Inc.’s palbociclib (Ibrance) and Faslodex (fulvestrant, Astrazeneca) for adults with endocrine-resistant, PIK3CA-mutated, hormone receptor (HR)-positive, HER2-negative, locally advanced or metastatic breast cancer.
The risk and benefit of Pfizer Inc.’s oral sickle cell disease drug Oxbryta (voxelotor) has flipped, prompted by what the company called new clinical data indicating “an imbalance in vaso-occlusive crises and fatal events” that need more study. Based on an EMA recommendation, Pfizer said it is voluntarily recalling all lots of Oxbryta from wherever it’s approved worldwide. Pfizer also is shuttering its Oxbryta clinical studies and expanded access programs.
For once, the EMA appears to have pipped the U.S. FDA to the post, with Pfizer Inc.’s hemophilia A and B therapy Hympavzi (marstacimab) recommended for approval in Europe on Sept. 20, while the U.S. PDUFA date is set for the fourth quarter of the year.
Details on the work leading to the discovery of the second-generation SARS-CoV-2 main protease (Mpro) inhibitor PF-7817883 (ibuzatrelvir) were disclosed recently by Pfizer Inc. The drug is in phase II clinical development for the treatment of adult individuals with COVID-19 symptoms who are not hospitalized.
Vor Biopharma Inc.’s trem-cel, a stem cell transplant designed to block the toxicity from cancer treatments, has produced some positive early stage results, including delayed relapse in patients. Phase I/IIa study data showed participants with relapsed/refractory acute myeloid leukemia benefited from trem-cel followed by treatment with Pfizer Inc.’s antibody-drug conjugate cancer fighter Mylotarg (gemtuzumab ozogamicin).
