Scholar Rock to Present Trials in Progress Poster for SRK-181 DRAGON Phase 1 Clinical Trial at the American Society of Clinical Oncology Annual Meeting
Scholar Rock (NASDAQ: SRRK) announced a presentation of its DRAGON Phase 1 trial for SRK-181 at the 2021 ASCO Annual Meeting, focusing on patients with solid tumors resistant to checkpoint inhibitors. The trial aims to assess the efficacy of SRK-181, a selective TGFβ1 inhibitor, in overcoming this resistance. The poster will detail the trial design and biomarker analysis. The presentation is scheduled for June 4, 2021, showcasing SRK-181's potential to enhance tumor response when combined with anti-PD-(L)1 therapy.

Scholar Rock (NASDAQ: SRRK), a clinical-stage biopharmaceutical company focused on the treatment of serious diseases in which protein growth factors play a fundamental role, today announced a trials in progress poster presentation at the 2021 American Society of Clinical Oncology (ASCO) Annual Meeting, being held virtually from June 4-8, 2021.
The DRAGON Phase 1 proof-of-concept trial (NCT04291079) is evaluating SRK-181, a selective inhibitor of TGFβ1 activation, in patients with locally advanced or metastatic solid tumors that have shown primary resistance to checkpoint inhibitor therapies. Dose escalation is progressing in Part A of the trial and the Company expects to advance to the Part B dose expansion portion of the trial in mid-2021.
The trials in progress e-poster will provide an overview of the design of the DRAGON Phase 1 trial and highlight the biomarker analysis being implemented to support the trial. Details of the poster presentation are as follows:
- Session: Developmental Therapeutics--Molecularly Targeted Agents and Tumor Biology
- Title: “First-in-Human Phase 1 Trial (DRAGON) of SRK-181: A Potential First-in-Class Selective Latent TGFβ1 Inhibitor, Alone or in Combination with Anti-PD-(L)1 Treatment in Patients with Advanced Solid Tumors” (TPS3146)
- Date and Time: Friday, June 4, 11:00 AM - 2:00 PM EDT; Poster sessions available on demand in meeting library beginning 9:00 AM EDT on June 4, 2021.
About SRK-181
SRK-181 is a selective inhibitor of TGFβ1 activation and is an investigational product candidate being developed to overcome primary resistance to checkpoint inhibitor therapy, such as anti-PD-(L)1 antibodies. TGFβ1 is the predominant TGFβ isoform expressed in many human tumor types. Based on analyses of various human tumors that are resistant to anti-PD-(L)1 therapy, data suggest TGFβ1 is a key contributor to the immunosuppressive tumor microenvironment, excluding and preventing entry of cytotoxic T cells into the tumor, thereby inhibiting anti-tumor immunity (1). Scholar Rock believes SRK-181, which specifically targets the latent TGFβ1 isoform, has the potential to overcome this immune cell exclusion and induce tumor regression when administered in combination with anti-PD-(L)1 therapy while potentially avoiding toxicities associated with non-selective TGFβ inhibition. The DRAGON Phase 1 proof-of-concept clinical trial (NCT04291079) in patients with locally advanced or metastatic solid tumors is ongoing. The efficacy and safety of SRK-181 have not been established. SRK-181 has not been approved for any use by the FDA nor any other regulatory agency.

About Scholar Rock
Scholar Rock is a clinical-stage biopharmaceutical company focused on the discovery and development of innovative medicines for the treatment of serious diseases in which signaling by protein growth factors plays a fundamental role. Scholar Rock is creating a pipeline of novel product candidates with the potential to transform the lives of patients suffering from a wide range of serious diseases, including neuromuscular disorders, cancer, fibrosis and anemia. Scholar Rock’s approach to targeting the molecular mechanisms of growth factor activation enabled it to develop a proprietary platform for the discovery and development of monoclonal antibodies that locally and selectively target these signaling proteins at the cellular level. By developing product candidates that act in the disease microenvironment, the Company intends to avoid the historical challenges associated with inhibiting growth factors for therapeutic effect. Scholar Rock believes its focus on biologically validated growth factors may facilitate a more efficient development path.
