1010 Days ago

  • Enrollment on track in the TOPAZ Phase 2 clinical trial of SRK-015 in patients with Type 2 and Type 3 Spinal Muscular Atrophy for preliminary PK/PD results by year-end

  • Presented positive final results from the Phase 1 clinical trial of SRK-015 in healthy volunteers at the Cure SMA Annual Conference

  • Completed public offering of common stock raising approximately $51.8 million in gross proceeds to advance portfolio of product candidates for the treatment of neuromuscular disorders, cancer, and anemia

CAMBRIDGE, Mass., Aug. 14, 2019 (GLOBE NEWSWIRE) -- Scholar Rock Holding Corporation (NASDAQ: SRRK), a clinical-stage biopharmaceutical company focused on the treatment of serious diseases in which protein growth factors play a fundamental role, today reported financial results for the quarter ended June 30, 2019 and highlighted recent progress and upcoming milestones for its pipeline programs.

“Throughout the first half of 2019, we made significant progress both clinically and financially as we advanced SRK-015 into a Phase 2 trial in SMA, SRK-181 towards the initiation of a Phase 1 trial in cancer immunotherapy in mid-2020, as well as successfully completed a follow-on offering to ensure that we are well-capitalized to support our portfolio of product candidates and overall company growth,” said Nagesh Mahanthappa, Ph.D., President and CEO of Scholar Rock.  “We look forward to building upon this momentum as we continue to progress our broad pipeline, with a number of important milestones at the end of this year and into 2020.”
Company Highlights and Upcoming Milestones

SRK-015 Program:

  • Positive Final Results from the Phase 1 Clinical Trial of SRK-015 in Healthy Volunteers Presented at the Cure SMA Annual Conference. In June 2019, Scholar Rock presented positive detailed results from the Phase 1 trial of SRK-015, which consisted of data from both the single-ascending and multiple-ascending dose portions of the trial.  SRK-015 was observed to be well-tolerated with no dose-limiting toxicities identified in up to the highest evaluated dose of 30 mg/kg.  The pharmacologic profile showed robust engagement of latent myostatin, which was saturated and sustained up to at least Day 140 after three doses of SRK-015 given once every two weeks at 20 mg/kg or 30 mg/kg.  In contrast, no meaningful change was observed in the latent myostatin biomarker concentrations in subjects who received placebo.

  • Preliminary Pharmacokinetic (PK) and Pharmacodynamic (PD) Data from TOPAZ Phase 2 Trial Expected by End of 2019.  Patient enrollment is underway in the TOPAZ Phase 2 proof-of-concept trial to assess the safety and efficacy of SRK-015 in patients with Type 2 and Type 3 Spinal Muscular Atrophy (SMA).  Approximately 55 patients are anticipated to be enrolled in the U.S., Canada, and Europe across three distinct and parallel cohorts and treated with SRK-015, either as a monotherapy or in conjunction with an approved survival motor neuron (SMN) upregulator therapy.

    Scholar Rock is on track to report preliminary PK/PD data for a subset of patients in the Phase 2 TOPAZ trial by the end of 2019, which will provide initial observations on target engagement of latent myostatin in patients with Type 2 and Type 3 SMA.  These preliminary PK/PD results will be followed by interim safety and efficacy results for a subset of patients with six months of treatment exposure expected in the first half of 2020 and top-line data for the full 12-month treatment period expected beginning in the fourth quarter of 2020.
  • Details of Scholar Rock-Developed Biomarker Assay that Quantifies Serum Latent Myostatin Published in Peer-Reviewed Journal.  In July 2019, Scholar Rock published details of its immunoassay used to measure serum latent myostatin in peer-reviewed journal Society of Laboratory Automation and Screening Discovery.  The publication, “A Sensitive and Selective Immunoassay for the Quantitation of Serum Latent Myostatin After In-Vivo Administration of SRK-015, a Selective Inhibitor of Myostatin Activation,”(1) highlights the ability of the immunoassay to quantify serum latent myostatin without cross-reactivity to promyostatin, mature myostatin, or closely related members of the TGFβ superfamily and the establishment of the robustness, reproducibility, and stability of the immunoassay.

    Through use of this biomarker assay, robust and sustained target engagement of latent myostatin has been observed in both preclinical studies and the Phase 1 clinical trial in healthy volunteers, establishing proof-of-mechanism of Scholar Rock’s therapeutic approach of targeting the latent form of growth factors.
  • Identification of Second Indication for SRK-015 Planned for 2020.  Scholar Rock continues to evaluate multiple potential opportunities for which SRK-015 could offer clinical benefit and is assessing additional potential clinical settings in which the selective inhibition of the activation of myostatin may offer therapeutic benefit.

SRK-181 Program:

  • Initiation of the Phase 1 Clinical Trial of SRK-181 in Patients with Solid Tumors Anticipated in Mid-2020.  In March 2019, Scholar Rock selected SRK-181, a highly specific inhibitor of TGFβ1 activation, as the first product candidate in its TGFβ1 cancer immunotherapy program based on the strength of preclinical data and human translational insights.  Scholar Rock intends to develop SRK-181 for the treatment of tumors resistant to checkpoint blockade therapies (CBTs), such as anti-PD(L)1 antibodies, and believes there is significant opportunity to expand the number of patients who can benefit from CBTs. 

    Scholar Rock plans to initiate a Phase 1 trial in patients with primary resistance to approved checkpoint blockade therapies in mid-2020 with initial clinical data anticipated by the end of 2021.

RGMc Program:

  • Nomination of a Product Candidate from the RGMc Program Planned in First Half of 2020.  For its third product candidate, Scholar Rock is evaluating a number of highly specific inhibitors of repulsive guidance molecule C (RGMc) and plans to nominate an antibody in the first half of 2020.  RGMc is a co-receptor of bone morphogenetic protein 6 (BMP6), a member of the TGFβ superfamily that plays an important role in iron metabolism.  RGMc’s known function is localized to hepatocytes and the identification of RGMc selective-antibodies may offer the potential for liver-specific modulation of BMP6 signaling to address iron-restricted anemias. 

Corporate Update:

  • Public Offering of Common Stock Completed in June/July 2019.  Scholar Rock successfully completed a public offering of 3,450,000 shares of common stock, inclusive of the full exercise of the over-allotment option by the underwriters, raising gross proceeds of approximately $51.8 million.

Second Quarter 2019 Financial Results

For the quarter ended June 30, 2019, net loss was $12.5 million or $0.48 per share compared to a net loss of $14.7 million or $1.39 per share for the quarter ended June 30, 2018.

  • Research and development expense was $13.7 million for the quarter ended June 30, 2019 compared to $11.4 million for the quarter ended June 30, 2018.  The increase year-over-year reflects preclinical and manufacturing costs for SRK-181 and higher personnel-related costs, partially offset by a decrease year-over-year in manufacturing costs associated with SRK-015. 

  • General and administrative expense was $4.7 million for the quarter ended June 30, 2019 compared to $3.5 million for the quarter ended June 30, 2018.  The increase year-over-year was primarily attributable to increased headcount, stock compensation, and higher operational fees associated with operating as a public company.

As of June 30, 2019, Scholar Rock had cash, cash equivalents, and marketable securities of $185.1 million, compared to $175.6 million as of December 31, 2018. The cash balance as of June 30, 2019 is inclusive of the approximately $42.2 million in net proceeds from the public offering of 3,000,000 shares of common stock and exclusive of $6.3 million in net proceeds from the underwriter’s purchase of an additional 450,000 shares of common stock that was settled in July 2019.
