• COVID: Phase 1 pharmacokinetic profile supports the potential for ratutrelvir to be dosed as a once-a-day, single drug, 10-day treatment course, without ritonavir, and with a lower likelihood of clinical rebound and good overall tolerability
• Flu: Phase 1 pharmacokinetic profile supports the potential for tivoxavir marboxil to be a one-time treatment for flu, including pandemic and avian flu, with good overall tolerability

NEWTOWN, Pa., Nov. 14, 2024 (GLOBE NEWSWIRE) -- Traws Pharma, Inc. (“Traws” or “Traws Pharma”), a clinical stage biopharmaceutical company developing oral small molecules for respiratory viral diseases, today outlined recent business updates and reported unaudited financial results for the third quarter ended September 30, 2024.

“Traws is making excellent progress with its clinical pipeline. Phase 1 data for each of the antiviral programs for COVID and influenza are particularly exciting,” said Werner Cautreels, PhD, Chief Executive Officer of Traws Pharma. “Based on our recent Phase 1 pharmacokinetic results, we believe that ratutrelvir has the potential to be used as a monotherapy to treat COVID, without ritonavir, with a lower likelihood of clinical rebound. In addition, recent Phase 1 pharmacokinetic data suggest that tivoxavir marboxil could be a single-dose treatment for influenza, including potential pandemic settings such as avian flu. These distinct characteristics support the potential for each agent to be a differentiated, best-in-class treatment and progress to Phase 2 studies expected to commence in 2025.“

Upcoming Milestones

Tivoxavir marboxil: Flu: an oral influenza cap-dependent endonuclease, highly conserved across flu strains, including avian flu. Intended as a one dose treatment or prevention of seasonal and pandemic flu

• Initiation of Phase 2 clinical proof of concept study in community-acquired setting
  

Ratutrelvir: COVID: an oral Mpro/3CL protease inhibitor, without the need for a CYP-inhibitor such as ritonavir. Intended as a once-a-day, single-dose, 10-day antiviral regimen for the treatment of COVID

• Initiation of Phase 2 clinical proof of concept study in community-acquired setting
  

Recent Developments

Antiviral programs advancing as potential best-in-class agents, poised to begin Phase 2

• COVID: Phase 1 data affirms ratutrelvir’s potential to be dosed without ritonavir, with lower rebound risk: Data from the Phase 1 healthy volunteer study, with once-a-day ratutrelvir dosing for 10 days showed no treatment related adverse events and demonstrated consistent plasma drug levels in the predicted therapeutic window. The study showed that ratutrelvir achieved plasma concentrations that were consistently above the EC90 against a panel of SARS-COV-2 viruses, without the need for ritonavir co-administration, which can be a source of drug-drug interactions and severe side effects. Pharmacokinetic data also suggest that ratutrelvir may have a reduced likelihood of clinical rebound, helped to define the dose for Phase 2 studies. Previous preclinical testing in animal models showed that levels of ratutrelvir in the lung were higher than in plasma. Taken together, the data further suggest that ratutrelvir has the potential to be a once-a-day, single-dose, 10-day antiviral therapy for COVID and support Phase 2 studies.
• Flu: Phase 1 data support tivoaxavir marboxil’s potential to treat flu with a single dose, with potential for pandemic/avian flu: Data from the Phase 1 healthy volunteer study, with one-time tivoxavir marboxil dosing showed good overall tolerability and a pharmacokinetic profile that appears to support potential use as a one-time treatment for flu, including pandemic flu. The study showed that a single dose of tivoxavir maintained plasma drug levels above the EC90 for more than five days and helped to define a Phase 2 dose. Prior preclinical studies have shown that tivoxavir has broad activity against drug resistant viruses and highly pathogenic strains such as avian flu. In addition, preclinical data showed that a single dose of tivoxavir has more than 15X higher accumulation in the lung compared to plasma. The combined dataset support further development of tivoxavir marboxil as a potential treatment of community-acquired influenza or for use in case of an avian flu outbreak or pandemic, with further potential to prevent virus spread in households and congregant settings.

Additional Updates: Luba Greenwood, J.D. added to the Board: Ms. Greenwood brings a rich depth of experience as a Board Member, Investor, Strategic Advisor and Company Executive through her industry roles, including as a board member for public life science companies across a range of therapeutic areas. In addition, Traws continues ongoing investigator-sponsored trial driven (IST) development of narazaciclib and rigosertib.

Financial Results:

Cash, cash equivalents and short-term investments: As of September 30, 2024, the Company had cash, cash equivalents, and short-term investments of approximately $5.4 million, compared to cash, cash equivalents, and short-term investments of approximately $20.8 million at December 31, 2023.

Research and development (R&D) expense for the three months ended September 30, 2024, totaled $5.1 million, compared to $2.5 million for the comparable period in 2023. This increase was primarily attributable to the initiation and completion of our Phase 1 study for TRX100 in Australia, partially offset by the reductions in research and development costs attributable to the Australian tax incentive receivable.

General and administrative (G&A) expense for the three months ended September 30, 2024, totaled $3.5 million, compared to $2.7 million for the comparable period in 2023. This increase was primarily attributable to a $1.2 million increase in professional and consulting fees associated with seeking strategic alternatives for our investors. This increase was offset by a $0.7 million decrease in public company costs.

Net loss: The net loss for the three months ended September 30, 2024 was $8.5 million, or $8.81 per basic and diluted common share. This compares with a net loss of $4.7 million, or $5.64 per basic and diluted common share, for the same period in 2023.

Traws had 3,025,554 shares outstandings as of November 11, 2024. The shares outstanding reflect a 25:1 reverse split, effective as of September 20, 2024.
