This financing brings the total capital raised by this affiliate in 2017 to $65 million which will be used to advance its novel immunotherapy for aging-related conditions

PureTech Health plc (LSE: PRTC), an advanced, clinical-stage biopharmaceutical company, announced today that resTORbio, Inc. (resTORbio), an affiliate of PureTech Health, completed an oversubscribed $40 million equity round led by OrbiMed and including participation from Fidelity Management & Research Company, Rock Springs Capital, Quan Capital and Nest Bio.

Together with a $25 million Series A financing that was completed earlier this year, the current financing brings the total 2017 investments in resTORbio to $65 million.

Daphne Zohar, Co-Founder and Chief Executive Officer of PureTech Health, said: “We are extremely pleased with the progress resTORbio has made since we launched the programme, including the achievement of key clinical milestones. Our late-stage clinical pipeline includes both wholly-owned programmes as well as those we advance in collaboration with leading equity and/or pharma partners. The latter category, which includes resTORbio, represents just one example of the value we have been building at PureTech Health.”

The additional capital is expected to be used to further advance clinical development of resTORbio’s novel programme for aging-related diseases and conditions that selectively targets TORC1, a key pathway involved in aging. resTORbio is currently conducting a Phase 2b clinical study designed to assess the safety, tolerability and efficacy of resTORbio’s lead programme in reducing respiratory tract infections (RTIs) in the elderly, with top-line results expected in the second half of 2018.

resTORbio Raises $40 Million to Advance Selective TORC1 Inhibitors for Aging-Related Diseases and Conditions

BOSTON, Massachusetts, November 30, 2017 – resTORbio, Inc., a clinical-stage biopharmaceutical company focused on the development and commercialisation of novel therapeutics for the treatment of aging-related diseases, today announced the completion of an oversubscribed $40 million Series B financing round. The round was led by OrbiMed and included participation from Fidelity Management & Research Company, Rock Springs Capital, Quan Capital and Nest Bio. This financing brings the total capital raised this year to $65 million, including a $25 million Series A financing that was completed earlier this year. resTORbio plans to use the proceeds to advance the development of RTB101, a selective Target of Rapamycin Complex 1 (TORC1) inhibitor, through a Phase 2b clinical trial and, if successful, into a Phase 3 clinical programme, as an immunotherapy to reduce the incidence of respiratory tract infections (RTIs) in elderly subjects. The funds are also expected to be used to expand the programme into a Phase 2 clinical trial in an additional aging-related indication. 

“We appreciate the support of these seasoned life sciences investors and their confidence in the potential of our TORC1 programme to treat diseases related to aging,” said Chen Schor, President and CEO of resTORbio. “RTB101, our selective inhibitor of TORC1, has been demonstrated to enhance immune function in elderly individuals in a randomised, placebo-controlled, phase 2 clinical trial. We believe our approach may provide an opportunity to address multiple aging-related diseases beyond our initial indication for reducing the incidence of RTIs in the elderly. We look forward to reporting data from our Phase 2b clinical trial in the second half of 2018 and to expanding the programme into additional indications.”

RTB101, an orally-administered, potent TORC1 inhibitor, is a first-in-class immunotherapy designed to address immunosenescence, the decline in immune function that occurs with age. RTB101, alone and in combination with everolimus, is being evaluated in a Phase 2b clinical trial to reduce the incidence of RTIs in elderly individuals at risk of mortality or morbidity due to RTIs which are caused by a broad spectrum of pathogens. Currently, there are no therapies approved by the US Food and Drug Administration (FDA) that improve immune function in the elderly and thereby reduce the incidence of RTIs. 

In connection with the financing, Jonathan Silverstein, Partner and a Co-Head of Global Private Equity at OrbiMed, will join the resTORbio board of directors. “We are excited to be investing in what we believe is the leading company addressing aging-related diseases and conditions. We look forward to contributing to resTORbio’s efforts to advance and expand its programme,” stated Jonathan Silverstein.

About Respiratory Tract Infections in the Elderly

The reduced ability of elderly patients to detect and fight infections is most commonly manifested in their susceptibility to RTIs and the negative effects such infections have on their overall health. According to the US Census Bureau, RTIs are the fifth leading cause of death in people age 85 and over and the seventh leading cause of death in people age 65 and over. RTIs also result in high healthcare costs for the elderly population and burden the healthcare system. The majority of RTIs are caused by viruses for which there are no FDA-approved therapies. As the elderly represent the fastest growing population in all regions of the world, there is significant unmet medical need for innovative therapeutic options to reduce the incidence of RTIs by enhancing the function of the aging immune system.

About TORC1

Mechanistic target of rapamycin (mTOR) is a protein serine/threonine kinase that regulates the process of aging and aging-related diseases and conditions, via two complexes: TORC1 and TORC2. TORC1 inhibition has been found to have many beneficial effects on aging-related diseases and conditions, while TORC2 inhibition has been associated with adverse events including hyperglycaemia and hyperlipidaemia. The TORC1 inhibitor programme being developed by resTORbio may, therefore, have therapeutic potential to ameliorate multiple aging-related diseases without the undesirable side effects associated with TORC2 inhibition.

About resTORbio

resTORbio, Inc. is a clinical stage biopharmaceutical company focused on the development and commercialisation of novel therapeutics for the treatment of aging-related diseases. resTORbio’s lead programme is targeting the target of rapamycin complex 1 (TORC1) pathway to treat aging-related diseases and conditions with an initial focus on conditions caused by immunosenescence, the decline in immune function that occurs during aging. resTORbio’s lead product candidate, RTB101, alone or in combination with everolimus, is in a Phase 2b clinical trial to evaluate its potential in reducing the incidence of respiratory tract infections (RTI) in elderly subjects at increased risk of RTI-related morbidity and mortality. resTORbio’s lead programme is supported by two Phase 2a clinical studies from which promising safety and efficacy signals were observed in almost 500 elderly subjects. resTORbio is pursuing a pragmatic clinical development plan to address areas of key unmet medical need in the aging population.
