"Scholar Rock made transformative progress in the second quarter with the successful completion of our IPO and the initiation of the Company’s first clinical trial," said Nagesh Mahanthappa, Ph.D, President and CEO of Scholar Rock. "We are well-positioned to continue to progress SRK-015 and build our pipeline of future product candidates focused on addressing neuromuscular disorders, cancer, fibrosis, and anemia. We plan to initiate a Phase 2 proof-of-concept study of SRK-015 to improve muscle function in patients with later-onset spinal muscular atrophy (SMA) in the first quarter of 2019."

Key Business and Clinical Highlights

Successfully Completed IPO. In May 2018, Scholar Rock successfully completed an initial public offering (IPO) of 6,164,000 shares of common stock, inclusive of the full exercise of the over-allotment option by the underwriters, raising gross proceeds of approximately $86.3 million.

Initiated Enrollment and Dosing in Multiple-Ascending Dose Portion of Phase 1 Clinical Trial for SRK-015. SRK-015 is a selective inhibitor of the activation of myostatin and was granted Orphan Drug Designation (ODD) by the U.S. Food and Drug Administration (FDA) for the treatment of SMA in March 2018. A placebo-controlled, double-blind Phase 1 clinical trial was initiated in May 2018 to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of single- and multiple-ascending doses of intravenous SRK-015 in healthy adult volunteers. Dosing has completed in the single-ascending dose portion of the study and has advanced to the multiple-ascending dose portion of the study.
Upcoming Milestones

On Track to Initiate Phase 2 Proof-of-Concept Study for SRK-015 in SMA in the First Quarter of 2019. Pending supporting safety data from the Phase 1 clinical trial, Scholar Rock plans to initiate a Phase 2 proof-of-concept study in the first quarter of 2019 to evaluate the safety and efficacy of SRK-015 in patients with later-onset SMA (Type 2 and Type 3) as a monotherapy or in conjunction with an approved survival motor neuron (SMN) upregulator therapy as background standard of care.

Identify Second Indication for SRK-015 in the First Half of 2019. Scholar Rock is actively assessing numerous preclinical models in which the selective inhibition of the activation of myostatin may offer therapeutic benefit. Scholar Rock intends to identify a second indication for SRK-015 in the first half of 2019.

Nominate Product Candidate for TGFβ1 Program by the End of the First Half of 2019. Scholar Rock’s second antibody program is focused on the discovery and development of highly specific inhibitors of the activation of TGFβ1. Scholar Rock is progressing its evaluation of a number of selective inhibitors in multiple disease models and intends to nominate a product candidate and first indication in oncology, immuno-oncology or fibrosis by the end of the first half of 2019.
Second Quarter 2018 Financial Results

Net loss for the quarter ended June 30, 2018 was $14.7 million or $1.39 per share compared to a net loss of $5.9 million or $3.67 per unit for the same quarter last year.

Research and development expense was $11.4 million for the quarter ended June 30, 2018, compared to $4.7 million in the same quarter in 2017. The $6.7 million increase year-over-year was primarily attributable to development and manufacturing costs associated with our lead product candidate, SRK-015, as well as employee costs related to increased headcount.

General and administrative expense was $3.5 million for the quarter ended June 30, 2018, compared to $1.2 million in the same quarter in 2017. The $2.3 million increase year-over-year was mainly due to increased headcount and higher professional and consulting fees associated with ongoing business activities and operating as a public company.
As of June 30, 2018, Scholar Rock had cash, cash equivalents, and marketable securities of $115.1 million, compared to $58.0 million at the end of 2017. The cash balance is inclusive of the approximately $77.8 million in net proceeds from its IPO in May 2018. Scholar Rock believes the cash balance will be sufficient to fund operating expenses and capital expenditure requirements into the second half of 2020.
