Contemporary off the acquisition of metabolic medicines developer MetseraPfizer is once more turning to dealmaking to develop its weight problems drug pipeline, this time choosing up an experimental oral drug that might develop into a part of combos with different property within the pharmaceutical big’s pipeline.
The drug, YP05002, comes from YaoPharma, a subsidiary of Shanghai Fosun Pharmaceutical. Per deal phrases introduced Tuesday, Pfizer will pay $150 million up entrance for international rights to the asset, which is at the moment in early scientific growth.
YP05002 is an oral small molecule designed to activate GLP-1. Pfizer fell quick in its personal efforts to develop an oral small molecule addressing the goal. Final 12 months, the corporate discontinued growth of danuglipron after a security sign emerged in a Part 1 research.
In a be aware despatched to buyers, Leerink Companions analyst David Risinger mentioned his understanding is that the chemical scaffold of the YaoPharma drug is much like that of orforglipron, the oral weight problems drug that Eli Lilly has steered by means of Part 3 growth and is at the moment on monitor for an FDA submission. Similarity to the Lilly drug may keep away from the protection sign that emerged with danuglipron.
Regardless of discontinuing danuglipron, Pfizer has different weight problems drug candidates in its pipeline. PF-07976016, an oral small molecule designed to dam the GIP receptor, is at the moment in Part 2 growth. Pfizer mentioned it plans to check YaoPharma’s drug together with PF-07976016 and different small molecules in its pipeline.
“We sit up for contributing our experience and assets to proceed the event of this investigational GLP-1 small molecule which enhances and strengthens our rising portfolio of novel candidates for treating weight problems and its adjoining illnesses,” Chris Boshoff, Pfizer’s chief scientific officer and president, analysis & growth, mentioned in a ready assertion.
YaoPharma’s YP05002 is at the moment being evaluated in a Part 1 single and ascending a number of dose research with a focused enrollment of 76 wholesome volunteers. Knowledge are anticipated in April 2026. Pfizer’s settlement with YaoPharma requires the Shanghai-based biotech to finish the Part 1 scientific trial. Past the upfront cost, Pfizer may pay YaoPharma may as much as $1.9 billion in milestone funds, plus royalties from gross sales if the drug reaches the market.
Different firms are additional alongside of their growth of oral weight problems medication. One in all them, Construction Therapeutics, reported preliminary Part 2b knowledge Monday exhibiting its small molecule agonist of the GLP-1 receptor, now named alenglipron (previously referred to as GSBR-1290), led to a mean 11.3% weight reduction. That outcome at 36 weeks was for the best of three doses examined. The commonest adversarial results have been gastrointestinal, which is in keeping with all GLP-1 medication. Discontinuation charges ranged from 7.7% to 13.3% throughout all doses.
Acknowledging all the caveats with cross-trial comparisons, William Blair analyst Andy Hsieh mentioned in a Monday analysis be aware that the magnitude of weight reduction for alenglipron is similar to the Part 2 outcomes for Lilly’s orforglipron, making Construction’s drug aggressive. However he additionally identified that vomiting and nausea charges for Construction’s drug have been larger than the charges reported for Lilly’s drug.
Construction mentioned alenglipron’s trial knowledge assist advancing the small molecule to Part 3 testing, which it goals to begin in mid-2026. The trial readout led Construction’s inventory value to spike about 100% on Monday. Hsieh mentioned the inventory motion was seemingly on account of expectations of an M&A deal, particularly following the general public bidding warfare for Metsera. Construction is benefiting from the inventory value rise with a proposed $500 million inventory providing.
