Commenting on the annual results, Bharatt Chowrira, Ph.D., J.D., Chief Executive Officer of PureTech, said:

2023 was a landmark year for PureTech, in which we made strong strategic and clinical progress. We’ve carried this momentum into 2024, with our hub-and-spoke R&D model continuing to deliver value for both patients and shareholders. Through this model we are able to ambitiously pursue our mission of giving life to science by developing therapies that make a meaningful difference to patients with devastating diseases.

PureTech pioneered the hub-and-spoke model, and we believe this novel approach has never been more important than in recent years. The capital markets have been challenging, yet PureTech has not needed to raise money from them in over six years, while still identifying and developing cutting-edge technologies at pace. This is because we have been able to bring in non-dilutive capital from our Founded Entities to fuel the development of the next generation of promising therapeutic candidates. It’s a self-sustaining R&D model that is not only proven but scalable and repeatable.

We take great pride in our track record of clinical success, which is six times the industry average.6 Our R&D engine has generated 29 new therapeutics and therapeutic candidates to date, with two taken from inception at PureTech to both U.S. FDA clearance and European marketing authorization and a third currently undergoing review with the FDA – Karuna’s KarXT. The success of Karuna is a prime example of our approach. Invented and initially advanced by PureTech, with $18.5 million of funding, KarXT is poised to significantly improve the way schizophrenia is managed after a dearth of innovation for 50 years. At the same time, PureTech has been able to generate over $1 billion in cash from Karuna’s progression as a Founded Entity, which culminated in its sale to Bristol Myers Squibb for $14 billion just last month. We are pleased to return certain portions of proceeds from successes like this to our shareholders, including through our proposed capital return of $100 million by way of a Tender Offer7 and our recently completed $50 million share buyback program, and to reinvest a portion back into our R&D engine.

We also continue to progress candidates internally, including LYT-100 (deupirfenidone), which could transform the treatment landscape for idiopathic pulmonary fibrosis (IPF). LYT-100 is currently being evaluated in a fully enrolled Phase 2b trial, which we expect to read out in the fourth quarter of 2024. LYT-100 is a great example of our internal R&D focus on therapeutic candidates with established biology that we believe we can unlock their full potential with our innovation.

Once internally-developed candidates reach a critical juncture, we have a range of options to advance them in a capital-efficient manner, including progressing them in Founded Entities or through partnerships, that allows us to focus on new opportunities, be more capital efficient and reduce the risks that are inherent in biotech for our shareholders. We recently announced the formation of two new Founded Entities, Seaport Therapeutics and Gallop Oncology. Having successfully completed an oversubscribed Series A financing of $100 million, and with Ms. Daphne Zohar at the helm, Seaport is looking to advance first and best-in-class medicines for the treatment of neuropsychiatric disorders using the GlyphTM platform. Additionally, Gallop will be advancing the LYT-200 program for hematological malignancies and metastatic solid tumors.

The work that we do at PureTech is transformational and full of purpose, and I’d like to thank all colleagues past and present who have built this remarkable business into what is it today. PureTech has a very bright future thanks to the passion of its people and the strength of its science, and I’m proud and humbled to be leading the company into an exciting new phase of growth, with multiple catalysts that can deliver significant value.”

    • LYT-200 has demonstrated a favorable safety and tolerability profile in two ongoing Phase 1b clinical trials – one in AML and another in combination with BeiGene’s tislelizumab in head and neck cancers.
    • In the 2024 post-period, the FDA granted LYT-200 Orphan Drug designation for the treatment of AML as well as Fast Track designation for the treatment of head and neck cancers.

    • Bristol Myers Squibb (NYSE: BMY) acquired Karuna for $330.00 per share in cash, for a total equity value of $14.0 billion in the 2024 post-period.
