"Our highest priority is to serve children and adults living with SMA by bringing apitegromab through the regulatory review process as quickly as possible," said David L. Hallal, Chairman and Chief Executive Officer of Scholar Rock. "To that end, we are encouraged by the FDA’s continued engagement and shared sense of urgency as Novo Nordisk works expeditiously to remediate its Catalent Indiana facility. We are ready to resubmit our apitegromab BLA following successful reinspection of the site by the FDA."

Mr. Hallal continued, "As we prepare to usher in the next phase of innovation for patients with SMA, we continue to strengthen our financial position while aggressively advancing our pipeline and expect 2026 to be a transformative year for Scholar Rock."

Business Highlights and Upcoming Milestones

Apitegromab

Apitegromab is an investigational fully human monoclonal antibody designed to inhibit myostatin activation by selectively binding the pro- and latent forms of myostatin in skeletal muscle. It is the first and only muscle-targeted therapeutic candidate in spinal muscular atrophy (SMA) to demonstrate a statistically significant and clinically meaningful benefit in a pivotal Phase 3 clinical trial (SAPPHIRE).

SMA Program

● BLA resubmission and U.S. launch, following approval, expected in 2026. A meeting between FDA and Catalent Indiana occurred early in the first quarter of 2026. The meeting was constructive and included a discussion of Novo Nordisk’s progress remediating the Catalent Indiana facility. No additional corrective actions were requested by FDA. Scholar Rock plans to resubmit the apitegromab BLA following a successful reinspection of the site.
● U.S. commercial team preparing for launch. The commercial team is expanding its reach and deepening relationships with key stakeholders, including SMA treatment centers and payers. The team’s focus includes educating on the importance of addressing the full motor unit, which consists of the motor neuron and the muscle.
● European Medicines Agency (EMA) regulatory review ongoing. A decision by EMA on the apitegromab Marketing Authorisation Application (MAA) is expected in mid-2026. The European team continues to engage with key stakeholders on SMA disease awareness and education initiatives. The Company is planning for an apitegromab launch in Europe in the second half of 2026, beginning with Germany.
● Advancing key activities at second fill-finish facility. Technology transfer continues at a second U.S.-based fill-finish facility to strengthen supply continuity and support future commercial demand. Engineering runs are underway with additional manufacturing runs planned through the second quarter of 2026. Scholar Rock expects to submit a supplemental BLA (sBLA) for this fill-finish facility later in 2026.
● Phase 2 OPAL clinical trial ongoing. Enrollment and patient dosing continue in the Phase 2 OPAL study (NCT07047144). The trial is designed to evaluate apitegromab in infants and toddlers with SMA under two years of age who have received an approved SMN1-targeted gene therapy or who are receiving ongoing treatment with an approved SMN2-targeted therapy.
● Development activities for subcutaneous apitegromab progressing. Scholar Rock is advancing a subcutaneous formulation of apitegromab intended to provide optionality for patients as a small volume, self- or caregiver-administered anti-myostatin antibody suitable for an autoinjector. A Phase 1 study in healthy volunteers has been completed, and further development activities are ongoing, including planned FDA and EMA regulatory engagements.
FSHD Program

● Phase 2 FORGE trial on track for initiation in mid-2026. Scholar Rock is developing apitegromab for the treatment of people with facioscapulohumeral muscular dystrophy (FSHD). FSHD is a rare, progressive neuromuscular disease characterized by muscle atrophy and functional decline, affecting approximately 30,000 individuals across the U.S. and Europe. The IND application is cleared, and the Company continues to anticipate the initiation of a Phase 2 randomized, double-blind, placebo-controlled trial, called FORGE, in mid-2026.
SRK-439

SRK-439 is a novel, investigational, subcutaneously administered myostatin inhibitor that binds to pro- and latent myostatin with high affinity and selectivity (i.e., no GDF11 or Activin A binding). Based on preclinical data, SRK-439 has the potential to potently inhibit myostatin and increase muscle mass.

● Dosing continues in Phase 1 healthy volunteer study. A Phase 1 study evaluating SRK-439 in healthy volunteers is underway, with topline data expected in the second half of 2026.
Corporate Update

● Secured new debt facility for up to $550 million in non-dilutive capital from funds managed by Blue Owl Capital (NYSE: OWL). This debt facility is expected to support commercialization of apitegromab and strategic advancement of key pipeline programs. The debt facility matures in February 2032, and consists of the following:
o

$100 million, which became available at closing and was used to retire Scholar Rock’s prior debt facility with Oxford Finance;

o

An additional $100 million to be drawn down in the first quarter of 2026;

o

Up to $150 million available upon FDA approval of apitegromab; and

o

An option for additional incremental facilities of up to $200 million at the mutual consent of Scholar Rock and Blue Owl Capital.

Fourth Quarter and Full Year 2025 Financial Results

Cash, cash equivalents and investments totaled $311.6 million as of Dec. 31, 2025, compared to $420.8 million as of Dec. 31, 2024, for a decrease of $109.2 million due primarily to $130.6 million used for operating activities and $68.6 million in shares repurchased offset by $75.0 million received from GSK for Jemperli total sales for 2025 exceeding $1.0 billion and $15.0 million received from Vanda Pharmaceuticals for the license of imsidolimab.
Collaboration revenue was $108.2 million and $234.6 million for the three and twelve months ended Dec. 31, 2025, compared to $43.1 million and $91.3 million for the three and twelve months ended Dec. 31, 2024. The increase was due primarily to Jemperli total sales for 2025 exceeding $1.0 billion which earned one-time $50 million and $75 million commercial sales milestones under our license agreement with GSK, Jemperli royalties increased 89% from $17.3 million to $32.7 million and 103% from $47.4 million to $96.0 million for the three and twelve months ended Dec. 31, 2025, and $9.7 million in revenue recognized for the Vanda license agreement.

"We are proud to achieve this important milestone, which enables the initiation of the Phase 1 ATLAS clinical trial and our transition to becoming a clinical-stage company," stated Thomas M. Soloway, President and Chief Executive Officer of T-knife. "TK-6302 is a highly differentiated therapy, engineered for greater potency against PRAME, a clinically validated target with attractive commercial potential. PRAME is highly prevalent across multiple high unmet-need solid tumor indications, including squamous non-small cell lung, ovarian, endometrial, skin, and triple-negative breast cancers. Today’s announcement reflects the dedication, expertise, and urgency our team brings to transforming innovative science into life-changing therapies."

Peggy Sotiropoulou, Ph.D., Chief Scientific Officer of T-knife, added, "The CTA was supported by a comprehensive and compelling preclinical data package demonstrating TK-6302’s best-in-class anti-tumor efficacy. By bolstering T-cell fitness and persistence while overcoming challenging tumor mediated immune barriers, TK-6302 has the potential to deliver meaningful clinical benefit, including deep, durable responses across a range of solid tumor cancers. Bringing a first-of-its-kind multi-armored, CRISPR gene-edited T cell therapy into the clinic underscores our commitment to pushing scientific boundaries in the service of delivering transformative therapies to patients."

About TK-6302
TK-6302 is a PRAME-targeted T cell therapy that has been "supercharged" by the inclusion of multiple armoring innovations: a high affinity PRAME targeting receptor to enhance cytotoxicity; a costimulatory CD8 coreceptor to engage CD4 T cells and enhance T cell fitness and persistence; and a FAS-based checkpoint converter designed to boost engraftment and promote T cell survival in the hostile tumor micro-environment. Preclinical data with TK-6302 demonstrated sustained serial killing and cytokine secretion in a model mirroring the inhibitory ligand expression in PRAME-expressing tumors. In a complex 3-dimensional (3D) spheroid tumor model, TK-6302 eliminated multiple rounds of tumors and demonstrated superior anti-tumor activity compared to controls. TK-6302 is manufactured with a non-viral gene editing process for improved T cell receptor expression, and it has been successfully manufactured at-scale using the clinical process.
