Completed acquisition of Trawsfynydd and concurrent $14 million Capital Raise

Excellent pipeline progress, led by candidates for COVID 19, influenza, and oncology programs

Poised to initiate Phase 2 studies in H2 2024 for our influenza candidate and
ritonavir-free COVID 19 protease inhibitor

NEWTOWN, Pa., May 16, 2024 (GLOBE NEWSWIRE) -- Traws Pharma, Inc. (“Traws” or “Traws Pharma”), a clinical stage biopharmaceutical company developing oral small molecules for respiratory viral diseases and cancer, today announced financial results for the first quarter of 2024, and provided a business update.

“2024 has already been a transformative year for Traws Pharma to advance our portfolio of novel treatments for serious respiratory infections and oncology programs. We completed the acquisition of Trawsfynydd and concluded a concurrent $14 million private placement financing. In addition, we initiated first-in-human dosing for our COVID 19 product candidate, including completion of the first cohort dosing group. Furthermore, we completed the last dose escalation cohort for our CDK4+ inhibitor, narazaciclib,” stated Werner Cautreels, Ph.D., Chief Executive Officer of Traws Pharma. “We believe that we are poised to make even more meaningful progress in the second half of 2024, as we advance our influenza treatment and ritonavir-free protease inhibitor for COVID 19 into expanded Phase 1 dose escalation studies and begin Phase 2 development.”

“Based on the preclinical profile and early clinical data from our infectious disease candidates and narazaciclib, I am optimistic about the outlook for Traws’ portfolio and look forward to updating our investors with our progress through the year,” concluded Dr. Cautreels.

Traws Proprietary Portfolio Highlights:

TRX100 (tivoxavir marboxil): a cap-dependent endonuclease inhibitor for influenza: Phase 1

• Targets the cap-dependent endonuclease of influenza and is a potent inhibitor of influenza virus replication including A and B strains
• First Phase 1 study demonstrated safety and tolerability in healthy volunteers with pharmacokinetics and pharmacodynamics (PK/PD) data to support the potential use of a single oral dose for treatment or prophylaxis
• We plan to initiate Phase 1 dose extension to evaluate one additional, higher dose prior to the initiation of Phase 2 studies in H2 2024. Topline data from the Phase 2 study are expected in H1 2025
  

TRX01 (ratutrelvir): a ritonavir-free Mpro protease inhibitor for COVID19: Phase 1

• Potent oral inhibitor of SARS-CoV-2 Mpro (3CL protease), effective against the original, delta, and omicron variants of SARS-CoV-2, that does not require co-administration with ritonavir, reducing the risk of drug-drug interactions. Preclinical data support once-daily dosing for 10days which could overcome viral rebound seen with other agents.
• We are in the process of conducting a Phase 1 first-in-human single ascending dose/multiple ascending dose (SAD/MAD) study in normal volunteers. The second dosing cohort is underway and topline data are expected H2 2024. A Phase 2 study is also planned to begin in H2 2024 in patients with moderate to severe COVID19. Topline data are expected H1 2025

Narazaciclib: CDK 4+ to treat solid tumors: Phase 1/2

• Available preclinical and clinical data suggest that narazaciclib is active in numerous tumor types, inhibiting CDK 2/4/6, CSF1R and ARK 5/NUAK1. Preclinical studies also showed reduced neutropenia, as compared to palbociclib, and inhibition of palbociclib resistant cancer cells.
• A dose escalation study to define the recommended Phase 2 dose (RP2D) recently enrolled the last cohort. A review of the clinical and PK/PD data is underway. We intend to utilize these data to define the clinical strategy, including selection of a lead indication and next steps in its development.

First Quarter 2024 Financial Results

Cash and cash equivalents as of March 31, 2024, were $16.4 million, compared with $20.8 million as of December 31, 2023.

In April 2024, the Company raised gross proceeds of $14 million from the sale of common and preferred stock to TPAV, LLC, an affiliate of Torrey Pines, and OrbiMed Private Investments VIII, LP, an affiliate of OrbiMed Advisors.

The Company believes that its cash and cash equivalents will be sufficient to fund ongoing clinical trials and business operations into the fourth quarter of 2024.

Revenue was fifty-six thousand dollars for the first quarter of 2024, consistent with the same period in 2023.

General and administrative (G&A) expenses were $3.4 million for the first quarter of 2024, compared with $2.1 million for the same period in 2023. The increase in G&A expenses was caused by higher legal and professional fees related to the Trawsfynydd acquisition on April 1, 2024, partially offset by lower bonus accrual as well as lower insurance, meeting, and public company expenses.

Research and development (R&D) expenses were $1.9 million for the first quarter of 2024, compared with $4.1 million for the same period in 2023. The decrease was primarily caused by lower costs related to narazaciclib drug substance and drug product manufacturing, a reduction in clinical development and consulting costs and lower personnel expenses due to lower bonus accrual.

Net loss for the first quarter of 2024 was $5.0 million, or $0.24 per share on 20.8 million weighted average shares outstanding, compared with a net loss of $5.8 million, or $0.28 per share for the same period in 2023, based on 20.8 million weighted average shares outstanding.
