Research News and Market Data on TRAW
Merger with Trawsfynydd Therapeutics, Inc (“Trawsfynydd”) and concurrent private placement of $14 million (cash runway to support planned operations through year end), with recently achieved clinical milestones, put Traws on track to achieve key readouts for the clinical pipeline in H2 2024 and beyond
- Lead antiviral program, tivoxavir marboxil, for influenza, including avian flu, is dosing the first cohort in the Phase 1 dose extension study in Australia
- COVID-19 program, ratutrelvir, completed the Phase 1 single-ascending dose (SAD) and multiple-ascending dose (MAD) study in Australia
- Oncology strategy includes investigator-sponsored trials (ISTs), planned to begin in H2 2024, adding a new dimension to the narazaciclib program, with continued investigator support for rigosertib
- Corporate update call planned for August 15, 2024 at 8:00 AM ET
NEWTOWN, Pa., Aug. 15, 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 outlined recent business highlights and reported unaudited financial results for the second quarter ended June 30, 2024. The Company intends to host a conference call and live webcast on Thursday, August 15, 2024 at 8:00 AM ET.
“The last several months have been transformational for Traws Pharma, with strategic and product development progress and an increase in capital,” said Werner Cautreels, PhD, Chief Executive Officer of Traws Pharma. “Completion of the merger agreement that created Traws Pharma expanded our investor base to include recognized healthcare investors, Orbimed and Torrey Pines, while broadening our portfolio to include compounds that we believe have best-in-class potential for influenza (flu), including bird flu, and COVID-19. In addition, ISTs are enhancing our multi-kinase inhibitors for cancer, narazaciclib and rigosertib.”
“We expect the antiviral program to advance over the next 6+ months as we complete preparations to report Phase 1 results and initiate Phase 2 studies in flu and COVID-19. Preclinical data and topline data from SAD studies from our influenza candidate, tivoxavir marboxil, suggest that it has the potential to achieve our target product profile as a single dose treatment that is active against pandemic-potential viruses as well as oseltamivir and baloxavir resistant viruses,” continued Dr. Cautreels. “In addition, clinical-trial enabling studies for our COVID-19 candidate, ratutrelvir, suggest that it has the potential to be effective without the requirement for co-administration of a CYP-inhibitor, and active against virus strains that may be resistant to other approved agents such as nirmatrelvir. In the coming months, we look forward to completing the Phase 1 studies, finalizing the dosing plan and initiating the Phase 2 program for both tivoxavir marboxil and ratutrelvir. We believe these data could pave the way for key readouts in 2025.”
Upcoming Milestones
Tivoxavir marboxil — Targets the influenza cap-dependent endonuclease, which is highly conserved across flu strains, including avian flu. The compound is intended to be administered as a single dose per treatment
- Q4 2024: Announcement of topline Phase 1 dose extension results from Australia
- Q4 2024/Q1 2025: Initiation of Phase 2 efficacy study
Ratutrelvir – Targets Mpro (3CL protease). The compound does not require combination use of a CYP-inhibitor such as ritonavir
- Q4 2024: Announcement of topline results from Phase 1 SAD and MAD studies
- Q4 2024/Q1 2025: Initiation of Phase 2 efficacy study
Narazaciclib – our multi-kinase inhibitor, including CKD4+, with potential for use in multiple solid tumors
- H2 2024: Release topline results from our Phase 1/2 study at an upcoming medical meeting. In addition, we plan to announce the recommended Phase 2 dose (RP2D) and initiate ISTs in multiple myeloma, breast cancer and other indications
Rigosertib – our multi-kinase inhibitor targeting cell cycle proteins including PLK-1, with potential for use in the ultra-rare disease, advanced squamous cell carcinoma complicating recessive dystrophic epidermolysis bullosa (RDEB-associated SCC, RDEB)
- Continue to support the IST-led program, including compassionate use for patients with RDEB
Recent Developments
- Start of dosing in Phase 1 dose extension study for tivoaxavir marboxil, a placebo-controlled trial designed to evaluate three doses, including two doses from the successful Phase 1 dose escalation study (80 and 120 mg) and one new, increased dose (240 mg) in healthy volunteers. The study was designed to assess pharmacokinetics, pharmacodynamics and safety, to define the dosing plan for the upcoming Phase 2 efficacy study. The expected dosing schedule will be one single oral dose.
- Completion of a Phase 1 dose escalation study for ratutrelvir in Australia, a SAD/MAD study conducted in healthy volunteers. The study was designed to assess SAD (5 doses ranging from 15 mg to 600 mg) and MAD (2 doses, 150 mg, and 600 mg, daily for 10 days) and provide pharmacokinetics, pharmacodynamics and safety data to guide the dosing plan for the upcoming Phase 2 efficacy study. The expected dosing schedule will be one oral dose per day for 10 days.
- Completion of Phase 1/2 dose escalation studies for narazaciclib, evaluated as a monotherapy and in combination with letrozole in patients with recurrent metastatic low-grade endometrioid endometrial cancer and other gynecologic malignancies. The studies were designed to define the dose limiting toxicity (DLT) and maximally tolerated dose (MTD) of the combination, and the RP2D for further clinical trials. Topline data are are being analyzed.
- Presentation of further data from ongoing ISTs for rigosertib, shared at the Society for Investigative Dermatology (SID) held in July, 2024 which highlighted ongoing studies for RDEB-associated SCC, conducted at the University Hospital in Salzburg, Austria and Thomas Jefferson University, Philadelphia, PA.
- Completion of the merger with Trawsfynydd and concurrent $14 million private placement in April expanded the clinical portfolio of the combined entity to include two potentially best-in-class oral small molecule programs, for influenza and COVID-19, as well as oral two agents for solid tumor cancers. The transaction also enhanced the Company’s investor base, with the addition of Orbimed and Torrey Pines.
Financial Results:
Traws financial results for the quarter ended June 30, 2024 represent the first post-transaction quarterly report of the combined company.

Cash, cash equivalents and short-term investments: As of June 30, 2024, the Company had cash, cash equivalents, and short-term investments of approximately $16.9 million, compared to cash, cash equivalents, and short-term investments of approximately $20.8 million at December 31, 2023. The company believes its cash balance is adequate to support planned operations through year end 2024.
Acquired in-process R&D related to our transaction early in the second quarter resulted in a non-cash charge of $117.5 million.
Research and development (R&D) expense for the three months ended June 30, 2024, totaled $4.0 million, compared to $2.5 million for the comparable period in 2023. Q2 2024 R&D expenses mainly reflect the cost of the Phase 1 SAD/MAD COVID-19 study, the Phase 1 extension study in flu, completion of the narazaciclib Phase 1/2 dose escalation study, regulatory expenses to support planned upcoming studies, and expenses related to stock-based compensation and restructuring costs related to the recent transaction.
