Representing the fourth largest biopharma M&A announced in 2026, Vertex Pharmaceuticals Inc. offered $85 per share in cash, or about $10 billion, to buy endocrine specialist Crinetics Pharmaceuticals Inc., adding the acromegaly drug Palsonify and a phase III asset, atumelnant, for congenital adrenocorticotropic hyperplasia (CAH).
Acromegaly is a rare endocrine condition caused by hypersecretion of human growth hormone (GH) that results in elevated circulating levels of GH and insulin-like growth factor-1 (IGF-1). Opko Biologics Ltd. has presented data on the development and characterization of OPKO-8801001, a long-acting human GH receptor (GHR) antagonist with prolonged systemic exposure and pharmacological activity designed for subcutaneous administration.
In a repeat move, the U.S. FDA issued yet again a complete response letter (CRL) to Camurus AB for its subcutaneous extended-release injection drug CAM-2029 (octreotide) to treat the rare chronic growth disorder acromegaly. The drug, which expects to be branded Oclaiz in the U.S. upon approval, is called Oczyesa in the EU and the U.K., where it received marketing authorization in 2025.
Crinetics Pharmaceuticals Inc.’s green light under priority review from the U.S. FDA for Palsonify (paltusotine) in first-line acromegaly sets up a not-uncommon David vs. Goliath-type scenario in the indication caused by excessive growth hormone made by the pituitary gland.
Acromegaly is a rare, chronic endocrine disorder characterized by excessive secretion of growth hormone (GH), most commonly resulting from a benign pituitary adenoma.
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.
Researchers from Alteogen Inc. and affiliated organizations presented preclinical characterization of a novel long-acting growth hormone receptor (GHR) antagonist, ALT-B5.
Clearing the way for a U.S. regulatory bid in the second half of this year are positive top-line results from Pathfindr-2, the second of two successful phase III studies testing the efficacy and safety of Crinetics Pharmaceuticals Inc.’s oral, once-daily paltusotine for acromegaly.
The majority of patients with acromegaly who switched from therapy with injected somatostatin receptor ligands to Crinetics Pharmaceuticals Inc.’s once-daily, oral drug paltusotine maintained stable levels of insulin-like growth factor 1 in a phase III trial, moving the company’s first-in-class lead closer to becoming the potential new standard of care for the rare hormonal disorder.
Camurus AB’s subcutaneous octreotide hydrochloride injection pen, CAM-2029, yielded statistically significant improvements in “multiple endpoints” in a 52-week phase III extension trial in patients with acromegaly, moving it closer to providing a more convenient treatment option for patients with the rare, chronic growth disorder than currently available therapies.
