resTORbio Reports Third Quarter 2018 Financial Results

Additional positive data from Phase 2b trial further support RTB101’s potential in reducing the incidence of respiratory tract infections (RTIs) in high-risk elderly patients

Initiation of pivotal Phase 3 program of RTB101 in RTIs expected in 1H19

Initiation of a Phase 2a trial of RTB101 in combination with a rapalog in Parkinson’s disease by the end of 1Q19

BOSTON, Nov. 13, 2018 (GLOBE NEWSWIRE) — resTORbio, Inc. (NASDAQ:TORC), a clinical-stage biopharmaceutical company focused on helping people live healthier longer through the development and commercialization of novel therapeutics for the treatment of aging-related diseases, today provided a corporate update and reported financial results for the third quarter ended September 30, 2018.

“Our recent accomplishments highlight the therapeutic potential of TORC1 inhibition to decrease the incidence of respiratory tract infections by enhancing immune function in the elderly,” said Chen Schor, Co-Founder, President and CEO of resTORbio. “The additional results from our Phase 2b trial, showing that RTB101 10 mg once daily (QD) reduced both the incidence of RTIs and severity of RTI symptoms, support our strategy to further evaluate RTB101 in high-risk elderly in a planned pivotal Phase 3 program. We also observed signals in our Phase 2b trial that RTB101 may reduce the incidence of urinary tract infections (UTIs), and we are developing our strategy for this indication. We continue to explore the potential benefits of TORC1 inhibition in ameliorating aging-related diseases such as neurodegenerative diseases, and look forward to expanding our pipeline with the initiation of a Phase 2a trial in Parkinson’s disease by the end of the first quarter of 2019.”

Recent Highlights and Outlook

Additional Positive Results from Phase 2b Trial Support Planned Pivotal Phase 3 Program in RTIs: In October 2018, resTORbio announced additional positive results from its dose-ranging Phase 2b trial of RTB101 in RTIs. The results supported and expanded upon topline results from the Phase 2b trial previously announced in July 2018, in which RTB101 10 mg QD demonstrated a statistically significant 30.6% reduction in the percentage of patients with laboratory-confirmed RTIs during the 16-week treatment period compared to placebo (p=0.025).

During the 16-week treatment period, RTB101 10 mg QD decreased the severity of laboratory-confirmed RTI symptoms compared to placebo, with a 52.1% reduction in the percentage of patients with severe laboratory-confirmed RTI symptoms (odds ratio (OR)=0.437; p=0.034). During the 16-week treatment period and the additional 8-week follow-up period off study drug (for a total of 24 weeks), RTB101 10 mg QD decreased the incidence of laboratory-confirmed RTIs compared to placebo, with a 27.5% reduction in the percentage of patients with laboratory-confirmed RTIs (OR=0.623; p=0.030).

Detailed results from this Phase 2b trial will be submitted for presentation at upcoming medical meetings, and the Company plans to hold an end-of-Phase 2 meeting with the U.S. Food and Drug Administration (FDA) in the first quarter of 2019.

Pre-specified Analyses from Phase 2b Trial Demonstrate Potential of RTB101 in Other Infections: The Phase 2b trial results reported in October 2018 also demonstrated from pre-specified analyses that treatment with RTB101 decreased the incidence of all infections and UTIs. RTB101 10 mg QD decreased the incidence of all infections during the 16-week treatment period compared to placebo, with a 23.6% reduction in the percentage of patients with any infection (OR=0.653; p=0.032). RTB101 10 mg twice daily decreased the incidence of UTIs during the 16-week treatment period compared to placebo, with a 74.6% reduction in the percentage of patients with one or more UTIs (OR= 0.211; p=0.027). The Company is developing its clinical strategy for RTB101 in UTIs, including dose selection.

Initiation of Phase 2 Trial in Parkinson’s Disease Expected by the End of the First Quarter of 2019: Selective and broad inhibition of TORC1 has been shown to extend lifespan and ameliorate several aging-related diseases in preclinical studies, including neurodegenerative disease. TORC1 inhibition with RTB101, in combination with rapalogs, such as sirolimus or everolimus, may induce autophagy, the process by which cells break down and recycle damaged aggregated proteins and cellular components. As neurodegenerative diseases such as Parkinson’s disease are associated with the accumulation of aggregated toxic proteins, the induction of autophagy with RTB101 in combination with rapalogs may have potential therapeutic benefit for patients with Parkinson’s disease. The Company plans to initiate a Phase 2a trial in patients with Parkinson’s disease by the end of the first quarter of 2019.

Third Quarter 2018 Financial Results

• R&D Expenses: R&D expenses were $6.8 million for the three months ended September 30, 2018 compared to $3.3 million for the three months ended September 30, 2017. The increase was primarily attributable to the Company’s Phase 2b trial.
• G&A Expenses: General and administrative expenses were $2.3 million for the three months ended September 30, 2018 compared to $0.6 million for the three months ended September 30, 2017. The increase was primarily attributable to an increase in headcount as well as increased operating costs as a result of the Company’s transition from a private company to a public company, including legal, accounting, insurance and investor relations expenses.
• Net Loss: Net loss was $8.4 million, or $0.30 per share, for the three months ended September 30, 2018 compared to a net loss of $3.3 million, or $0.75 per share, for the three months ended September 30, 2017.
• Cash Position: Cash, cash equivalents and marketable securities were $115.4 million as of September 30, 2018. The Company expects that its cash, cash equivalents and marketable securities as of September 30, 2018 will be sufficient to fund its operating expenses through 2020.
