Scholar Rock Holding Corporation (NASDAQ: SRRK), a biopharmaceutical company, has seen its stock price skyrocket over 200% following the announcement of promising results from its Phase 3 SAPPHIRE clinical trial evaluating apitegromab for treating spinal muscular atrophy (SMA). The company’s breakthrough treatment has shown significant success, creating waves in the biotech and investment communities.
Scholar Rock’s Phase 3 SAPPHIRE Trial Success
On October 7, 2024, Scholar Rock announced that apitegromab met its primary endpoint in the Phase 3 SAPPHIRE study, which assessed the efficacy of the muscle-targeted therapy for patients with SMA. This trial demonstrated statistically significant and clinically meaningful improvements in motor function, particularly using the Hammersmith Functional Motor Scale Expanded (HFMSE). In this double-blind study, a significant percentage of patients treated with apitegromab showed a motor function improvement of over 3 points compared to those receiving a placebo.
This achievement is seen as a major milestone for SMA patients, especially those undergoing chronic treatment with standard care options like nusinersen or risdiplam. Scholar Rock intends to submit a Biologics License Application (BLA) to the U.S. Food and Drug Administration (FDA) and an equivalent marketing authorization application to the European Union in Q1 2025.
Stock Impact and Market Reactions
Following the release of the trial results, SRRK shares soared over 200% during pre-market trading on October 7. By midday, the stock had stabilized, reflecting investor confidence in the company’s future prospects. Scholar Rock’s stock closed at $7.42 on Friday, but quickly reached new heights once the news broke.
The success of this Phase 3 trial could position Scholar Rock for significant growth, especially as the company prepares to bring apitegromab to the global market. Analysts, including Truist Securities, have already raised their price target for SRRK, now predicting the stock could reach $36(

What This Means for SMA Patients
SMA is a rare genetic disorder that causes progressive muscle wasting and weakness. Current therapies can slow disease progression but don’t fully address muscle strength loss. Apitegromab, as a muscle-targeted therapy, has shown potential to improve motor function when combined with existing treatments. In the Phase 3 trial, over 30% of patients receiving apitegromab exhibited a clinically significant improvement in HFMSE scores compared to only 12.5% of those on placebo(
Furthermore, the safety profile of apitegromab remains consistent with previous trials, including the Phase 2 TOPAZ trial, which has amassed over 48 months of safety data. No new safety concerns were observed, giving hope to patients and caregivers awaiting better treatment options(
Scholar Rock’s Future Outlook and Plans
With the Phase 3 success, Scholar Rock is on track to transform its market positioning. The company is preparing for regulatory filings in early 2025, hoping to secure approvals from both the U.S. FDA and European Medicines Agency. If successful, the company could begin commercializing apitegromab by the second half of 2025.
Additionally, Scholar Rock continues to explore other therapeutic areas, including cardiometabolic disorders, which could offer further growth opportunities. Investors and analysts are optimistic that Scholar Rock’s unique focus on modulating protein growth factors could lead to more groundbreaking therapies in the future(
What’s Next for Investors?
Investors interested in Scholar Rock should keep a close eye on upcoming regulatory submissions, as approval for apitegromab could significantly boost the company’s valuation. With analysts increasing their price targets, it’s clear that the market sees substantial potential in Scholar Rock’s pipeline. However, as with all biotech investments, regulatory risks remain, and the success of apitegromab’s commercialization will be crucial.
