Scholar Rock Holding Corporation is a clinical-stage biotechnology company leveraging its expertise in protein growth factor signaling to develop therapies for severe diseases, including neuromuscular disorders, cardiometabolic disorders, cancer, fibrosis, and anemia.
The shares sold on January 22nd were part of a Rule 10b5-1 trading plan, which allows insiders to schedule sales in advance. So the sale wasn’t a voluntarily action conducted that day. And on the 16th and 14th, Qatanani sold more shares, but the shares sold on the 16th were to cover tax withholding obligations, and the ones sold two days earlier were also a part of a 10b5-1 plan.
Scholar Rock has big plans for 2026, as it plans on launching one of its key product candidates, apitegromab, into U.S. and European markets, following approval from the Food and Drug Administration and other global agencies. The company claims that apitegromab is the world’s first and only muscle-targeted treatment candidate to improve motor function in patients with spinal muscular atrophy (SMA), a severe and genetic neuromuscular disease.
The company is still operating with a net loss, and the stock increased by barely 2% in 2025, but if its apitegromab project is successful, SRRK has a stronger case as a promising investment.
