Management Comments

• Scholar Rock is moving with a sense of urgency to bring transformative medicines to patients.
• The company is leveraging its R&D success to build a multi-billion dollar biopharmaceutical company.

Industry Context

The presentation highlights Scholar Rock's position in the competitive landscape of SMA and obesity treatments. The company is differentiating itself by focusing on muscle-targeted therapies and addressing the unmet needs of patients who still experience muscle weakness despite existing treatments. The company is also leveraging the growing market for GLP-1 RAs by developing a combination therapy to address muscle loss associated with these treatments.

Comparison to Industry Standards

• The company's Phase 3 trial results for apitegromab in SMA, showing a 1.8 point improvement in HFMSE, are compared to the standard of care treatments like nusinersen and risdiplam, which primarily target the motor neuron.
• The company is positioning apitegromab as the first and only muscle-targeted therapy with clinical success in SMA, addressing a key unmet need.
• The company's approach to targeting latent myostatin is differentiated from other approaches that target the active form of the growth factor, potentially leading to better selectivity and safety profiles.
• The company is leveraging the success of GLP-1 RAs in weight loss but is addressing the issue of muscle loss associated with these treatments, which is a common concern among patients.

Stakeholder Impact

• Shareholders are likely to be positively impacted by the progress in clinical trials and the potential for commercialization.
• Patients with SMA and other neuromuscular diseases may benefit from new treatment options.
• Employees may be positively impacted by the company's growth and success.
• Customers and suppliers may be impacted by the commercial launch of apitegromab.

Next Steps

• Submit FDA and EMA applications for apitegromab in the first quarter of 2025.
• Initiate the Phase 2 OPAL trial for apitegromab in SMA patients under 2 years old in mid-2025.
• Report results from the EMBRAZE Phase 2 study for apitegromab in obesity in the second quarter of 2025.
• Submit an IND for SRK-439 in the third quarter of 2025.
• Launch apitegromab in the US in the fourth quarter of 2025, followed by a European launch.
