  • Strong strategic and clinical progress in 2023, with multiple catalysts expected in 2024
  • Launching of two new Founded Entities to advance certain programs from the Wholly Owned Pipeline
  • Robust balance sheet position with estimated Consolidated Cash, Cash Equivalents and Short-Term Investments at year end of approximately $320 million1, extends operational runway guidance into 2027

BOSTON--(BUSINESS WIRE)-- PureTech Health plc (Nasdaq: PRTC, LSE: PRTC) (“PureTech” or the “Company”), a clinical-stage biotherapeutics company dedicated to changing the lives of patients with devastating diseases, today reports on the key progress made across its Wholly Owned Programs2 and Founded Entities3 in 2023, announces two new Founded Entities and provides an update on cash and operational runway guidance.

Key Highlights:

  • Strong progress in 2023 included the successful LYT-300 clinical trial of acute anxiety in healthy adults and initial data from ongoing clinical trials of LYT-200 in solid tumors and acute myeloid leukemia, along with Royalty Pharma deal of up to $500M, as well as clinical and regulatory advances across multiple Wholly Owned Programs and Founded Entities.
  • PureTech continues to build and will further expand its Wholly Owned Pipeline focus in pulmonary and rare diseases. Certain GlyphTM intellectual property will remain at PureTech. Key catalysts expected in 2024 include results from idiopathic pulmonary fibrosis (IPF) late-stage trial of LYT-100 in Q4 2024.
  • New clinical-stage neuroscience Founded Entity: Seaport Therapeutics will advance certain central nervous system (CNS) programs and relevant Glyph intellectual property. Rapid growth of neuroscience pipeline, powered by Glyph platform, including new therapeutic candidate announced today (LYT-320), and initiations of two clinical trials in 2024 (LYT-300 and LYT-310).
  • New clinical-stage oncology Founded Entity: Gallop Oncology to advance LYT-200 and other galectin-9 intellectual property; additional results from clinical trials in leukemia and solid tumors expected in 2024.
  • Robust balance sheet position with estimated Consolidated Cash, Cash Equivalents and Short-Term Investments at year end of approximately $320 million1, extends operational runway guidance into 2027 based on the Company’s strategic operating plan.
  • The PureTech Board may declare special dividends and/or share buybacks as part of an overall returns strategy.

Daphne Zohar, Founder and Chief Executive Officer of PureTech, commented: “PureTech has had a particularly productive year. One of the advantages of the hub-and-spoke model we pioneered is that it has enabled us to build an exciting pipeline of new medicines poised for tremendous growth, without diluting our shareholders in almost seven years. Our Founded Entities are a significant source of value to us, and we have generated over $800 million in non-dilutive proceeds to advance our pipeline and growth since 2020.

“A good example of how our successful model has funded our pipeline and operations is our strategic deal with Royalty Pharma acquiring an interest in our royalty in KarXT for up to $500 million, which provided us with upfront non-dilutive capital and significant upside based on Karuna’s future regulatory and commercial successes.

“I’m also proud of our track record which includes 80 percent4 success across clinical trials, with a probability of clinical success that is six times better than the industry average5.

“Advancing programs to a key value inflection point before determining the most expedient and cost-effective path forward is a hallmark of our hub-and-spoke business model, and we’ve seen the success of it realized in the U.S. FDA clearance of two medicines, a third that has recently filed for approval, and several additional therapeutic candidates being advanced through late-stage clinical trials. This model allows us to create and advance new medicines in a capital efficient manner. Importantly, the strategic decision announced today to advance certain programs through two new Founded Entities will make it easier for the true value of these programs to be recognized and, as they continue to advance, deliver the greatest value back to our shareholders.

“We are extremely proud of the numerous accomplishments made by our team in 2023 and look forward to a productive and exciting 2024, where we expect to deliver multiple milestones to improve the lives of patients and drive benefit to our shareholders.”

Additional highlights and progress include the following:

Outlook for 2024, new Founded Entities and execution of corporate strategy

  • Building on the success of early studies for LYT-100, and with the important upcoming catalyst for IPF in 2024, PureTech will continue to build on its internal expertise in pulmonary and rare diseases and expanding its portfolio in those therapeutic areas. Certain Glyph intellectual property will remain at PureTech.
  • PureTech is reinforcing the proven success of its model by adding two new “spokes” to the PureTech “hub.” PureTech will be advancing its programs in two important therapeutic areas (neuroscience and oncology respectively) in two new clinical-stage Founded Entities, Seaport Therapeutics and Gallop Oncology.
    • The launch of Seaport Therapeutics will accelerate the development of new neuroscience medicines in areas of high unmet need with the addition of capital partners to bring nearer-term patient benefit. It also builds on the success PureTech has achieved in the neuroscience arena with the same strategy and team at PureTech that invented KarXT. If approved, KarXT will be the third therapeutic candidate to be taken from inception at PureTech to FDA regulatory approval and will represent the first new mechanism of action for patients with schizophrenia in over 50 years.
    • The launch of Gallop Oncology builds on the promising clinical and preclinical data from PureTech’s LYT-200 program in solid tumors and hematological malignancies. The development of a novel oncology medicine requires a dedicated effort that is best enabled through a separate Founded Entity and external capital.

Wholly Owned Programs

  • LYT-100 (deupirfenidone) is currently in development for the treatment of IPF, which is a rare, progressive, and fatal disease. While existing standard-of-care treatments are effective, they cause significant side effects, and as a result, three out of four people living with IPF in the U.S. forego treatment. LYT-100, which has shown 50 percent reduction of the GI and overall adverse events compared to pirfenidone in a head-to-head study, has the potential to both supplant the current standard-of-care treatments and to serve a larger population of patients who are unable to tolerate current therapies.
    • Progressed a Phase 2b dose-ranging trial of LYT-100 in patients with IPF. Topline results are expected in Q4 2024. PureTech plans to pursue a streamlined development program for LYT-100 in IPF and is using the same validated endpoints that have supported past approvals. PureTech believes the results of the ongoing trial, together with an additional registration study in Phase 3, could serve as the basis for registration in the U.S. and other geographies.
    • Presented expanded data at the CHEST Annual Meeting 2023 from a completed trial of LYT-100 in healthy older adults, which informed the two doses selected for the ongoing Phase 2b trial (ELEVATE IPF). In addition to supporting the improved tolerability of LYT-100 versus the FDA-approved dose of pirfenidone, the new data presented supported the selection of a higher dose of LYT-100 with the potential for improved efficacy that is now being evaluated in ELEVATE IPF.

Newly Announced Founded Entities:

  • Seaport Therapeutics:
    • LYT-300 (oral Glyph-allopregnanolone) is an oral prodrug of allopregnanolone, enabled by the Glyph platform, that is currently in development for the treatment of both neuropsychiatric and rare CNS conditions. Allopregnanolone has demonstrated benefit in a range of CNS conditions, but it can only be administered via IV, which has hindered its broad therapeutic use. Using the Glyph platform, LYT-300 retains the activity and potency of endogenous allopregnanolone in an oral form.
      • Successful topline results from a Phase 2a proof-of-concept trial of LYT-300 using a validated clinical model of anxiety in healthy volunteers were reported recently. Oral administration of LYT-300 achieved the trial's primary endpoint of a statistically significant reduction versus placebo in the increase from baseline to peak levels of the stress hormone salivary cortisol (p=0.0001) with a treatment effect size versus placebo of 0.72, measured by the Cohen’s D.
      • LYT-300 is advancing into a Phase 2 clinical trial for the treatment of Fragile X-associated Tremor/ Ataxia Syndrome (FXTAS), which is a rare neurological disease. A Phase 2 trial is expected to initiate in 2024. PureTech was chosen to receive up to $11.4 million from the U.S. Department of Defense through a highly competitive grant process to advance LYT-300 in FXTAS.
    • LYT-310 (oral Glyph-cannabidiol [CBD]), is currently in development for the treatment of epilepsies and other neurological indications. A different CBD-based product purified from plant sources, has received regulatory approval in the U.S. and Europe to treat seizures resulting from certain rare conditions, but it requires a large volume of a sesame oil-based formulation, which limits its use in broader indications and age groups.
      • New today: Preclinical data demonstrated LYT-310 was effective in preventing seizures in the Maximal Electroshock Model (MES), a validated and highly translatable preclinical model considered a gold standard for the assessment of anti-seizure drugs. LYT-310 was tested against various formulations of CBD, including an oral CBD formulation in sesame oil. LYT-310 showed strong anti-seizure protection activity and was shown to be more effective at preventing seizures at a dose three times lower than an oral CBD formulation. Based on the data, LYT-310 has the potential to expand the use of CBD to broader patient populations, particularly in populations and conditions where higher doses are required to achieve a therapeutic effect.

      • Initiation of a Phase 1 clinical trial of LYT-310 is expected in the first half of 2024.

    • New today: LYT-320 (oral Glyph-agomelatine), was nominated as a new therapeutic candidate powered by PureTech’s Glyph platform. A novel prodrug of agomelatine, LYT-320 is in development for the treatment of anxiety and mood disorders. Anxiety disorders affect nearly 30 percent of U.S. adults6 and are an area of significant unmet need.

      • LYT-320 uses the Glyph platform to bypass first-pass metabolism by the liver and thus has the potential to reduce liver exposure, hepatotoxicity, and the need for liver function monitoring.
      • Selective serotonin reuptake inhibitors (SSRIs) and serotonin and norepinephrine reuptake inhibitors (SNRIs) are first-line treatments for generalized anxiety disorder (GAD) and depressive disorders but have side effects and efficacy limitations. A major limitation of SSRIs and SNRIs are adverse events such as sexual dysfunction and emotional blunting.
      • Agomelatine acts through a completely different mechanism of action and offers superior overall tolerability for patients compared to standard-of-care. The drug has demonstrated clear human efficacy in multiple studies of GAD where the gold-standard Hamilton Anxiety Rating Scale (HAM-A) was used as the primary endpoint. Agomelatine is approved for major depressive disorder (MDD) in the European Union and for MDD and GAD in Australia. Agomelatine has not been approved in the U.S., offering LYT-320 first-in-class potential for the U.S. market and best-in-class potential in the rest of the world. However, agomelatine is associated with hepatoxicity necessitating extensive liver function monitoring that has held back its use. Agomelatine has very low oral bioavailability (approximately one percent) due to extensive hepatic first-pass metabolism, potentially contributing to hepatoxicity.
      • In multiple in vivo studies, LYT-320 showed oral bioavailability and plasma exposures greater than 10-fold higher than orally dosed agomelatine. Exposures comparable to approved therapeutic agomelatine doses could thus be enabled by LYT-320 comprising a reduced dose of agomelatine, which in silico modeling using the FDA-licensed DILIsym platform, has projected will greatly reduce the risk of causing clinically significant liver enzyme elevations.
      • Initiation of first-in-human enabling studies is expected in 2024 and LYT-320 is expected to advance into clinical studies in the first half of 2025.
  • Gallop Oncology:

    • LYT-200 (anti-galectin-9 mAb) is in development for the treatment of metastatic/locally advanced solid tumors, including head and neck and urothelial cancers, and hematological malignancies, such as acute myeloid leukemia (AML) and high-risk myelodysplastic syndromes (MDS). A wide variety of preclinical data support the potential clinical efficacy of LYT-200 and the importance of galectin-9 as a target and suggests a potential opportunity for biomarker development.
      • Presented data from the ongoing Phase 1 clinical trial of LYT-200 at the ESMO Immuno-Oncology Congress 2023. In the initial results, LYT-200 demonstrated a favorable safety profile in all cohorts, including the monotherapy and combination arms with BeiGene’s tislelizumab, and showed disease control and suggestions of initial anti-tumor activity. In the combination arm, 11 patients have been dosed, and all evaluable patients treated so far include four patients with head and neck cancers and two patients with urothelial cancer. In the evaluable patients with head and neck cancers, disease control was observed in three of the four patients, with one patient experiencing a complete response after nine months, one patient with a deepening partial response after eight months, and one patient with disease stabilization at four months so far, with treatment in these patients remains ongoing. The two evaluable patients with urothelial cancer experienced disease stabilization for seven months and three months, so far, and both remain on treatment. The combination arm continues to enroll patients with head and neck and urothelial cancers. Completion of the trial and results are expected by the end of 2024.
    • New today: In the ongoing Phase 1b trial evaluating LYT-200 as a single agent in relapsed/refractory AML and MDS patients, three dose escalation cohorts have completed to date at weekly doses of 2 mg/kg (cohort 1), 4 mg/kg (cohort 2) and 7.5 mg/kg (cohort 3). In a heavily pre-treated patient population, the early data demonstrates a favorable safety and tolerability profile of LYT-200 with no dose limiting toxicities. In the first cohort, disease stabilization was observed in two of the five patients treated, with one patient achieving red blood cell transfusion independence. In the second cohort, disease stabilization was observed in two of the four patients treated. In the third cohort, disease stabilization was observed in all four of the patients treated, with a reduction in bone marrow blasts observed in two of the four patients and the clearance of peripheral blasts observed in one patient. Two patients achieved more than 50 percent bone marrow blast reduction, with one of these patients observing an increase in platelet count without transfusions. The fourth cohort, evaluating a weekly regimen of LYT-200 at the 12 mg/kg dose, is still ongoing. The part 2 portion of the Phase 1b trial evaluating LYT-200 in combination with venetoclax and hypomethylating agents is also ongoing. PureTech plans to present additional data from the trial in a scientific forum in 2024.

Founded Entities:

  • Karuna Therapeutics (Nasdaq: KRTX) (Karuna)
    • Announced the U.S. Food and Drug Administration has accepted its New Drug Application (NDA) for KarXT (xanomeline-trospium) for the treatment of schizophrenia in adults. The application has been granted a Prescription Drug User Fee Act (PDUFA) date of September 26, 2024.

The additional data demonstrated successful engraftment of trem-cel in all seven patients treated to date with trem-cel. All three patients treated with Mylotarg experienced hematologic protection and CD33-negative donor cell enrichment with multiple cycles.
  • Entrega
    • Advanced its platform for the oral administration of biologics, vaccines and other drugs that are otherwise not efficiently absorbed when taken orally. Entrega's technology platform uses a proprietary, customizable hydrogel dosage form to control local fluid microenvironments in the GI tract to both enhance absorption and reduce the variability of drug exposure.

Improvements in attention were nearly seven times larger than those seen in the pivotal trial that supported EndeavorRx’s FDA authorization for 8 to 12 year-olds with ADHD. Additionally, nearly half of adults treated with EndeavorRx met a prespecified threshold for clinically meaningful improvement in their quality of life. EndeavorRx treatment was well-tolerated, with minimal side effects and no serious device-related adverse events reported.
  • Sonde Health
    • Continued to scale its sales and revenue growth through partnerships with several top health companies, providers, pharma and device original equipment manufacturers. Sonde’s voice-based artificial intelligence platform has now generated over 1.2 million voice samples from more than 85,000 individuals on four continents.

As part of PureTech’s distinctive approach to drug development, which includes efficient de-risking and deprioritizing of programs that don’t reach pre-specific thresholds for advancement, the Company is no longer advancing its Alivio™ platform, including therapeutic candidates LYT-500 and LYT-510, to pivot resources towards the programs with the highest probability of success. Additionally, PureTech announced in October that it would not be moving forward with the previously contemplated plan of merger with Gelesis.

7 EndeavorRx is the first-and-only FDA-authorized treatment delivered through a video game experience. EndeavorRx is indicated to improve attention function as measured by computer-based testing in children ages 8 to 12 years old with primarily inattentive or combined-type ADHD, who have a demonstrated attention issue. Patients who engage with EndeavorRx demonstrate improvements in a digitally assessed measure Test of Variables of Attention (TOVA®) of sustained and selective attention and may not display benefits in typical behavioral symptoms, such as hyperactivity. EndeavorRx should be considered for use as part of a therapeutic program that may include clinician-directed therapy, medication, and/or educational programs, which further address symptoms of the disorder. EndeavorRx is available by prescription only. It is not intended to be used as a stand-alone therapeutic and is not a substitution for a child's medication. The most common side effect observed in children in EndeavorRx's clinical trials was a feeling of frustration, as the game can be quite challenging at times. No serious adverse events were associated with its use. EndeavorRx is recommended to be used for approximately 25 minutes a day, 5 days a week, over initially at least 4 consecutive weeks, or as recommended by your child's health care provider.
