24/7 Market News Issues Corrected Information on Previously issued Press Release with same title

DENVER, Aug. 14, 2025 (GLOBE NEWSWIRE) — 247marketnews.com, a pioneer in digital media dedicated to the swift distribution of financial market news and corporate information, spotlights LIXTE Biotechnology Holdings, Inc. (Nasdaq: LIXT), a clinical-stage pharmaceutical company focused on developing novel cancer therapies by targeting the modulation of key cellular pathways.

2H 2025 is shaping up to be a defining year for LIXTE. With a focus on its lead compound LB-100, a first-in-class small molecule inhibitor of protein phosphatase 2A (PP2A), a master regulator of cell signaling and DNA damage response. By inhibiting PP2A, LB-100 sensitizes tumors to DNA-damaging agents, including chemotherapy, radiation, and immunotherapy, LIXTE is targeting high-unmet needs in the $200 billion global oncology market (Grand View Research, 2025 projection). Potential upcoming catalysts in 2025, including a first trial result, position LIXTE as a potential disruptor in resistant cancers, where traditional treatments fail due to limited efficacy and toxicity.

Upcoming Catalysts: Anticipated Trial Results in 2H 2025

1B/2 Trial – Ovarian Clear Cell Carcinoma (OCCC)

Ovarian clear cell carcinoma is an aggressive and chemoresistant subtype of epithelial ovarian cancer, accounting for ~5–10% of all ovarian malignancies but disproportionately contributing to ovarian cancer mortality.

The Phase 1B/2 study of LB-100 plus the checkpoint inhibitor dostarlimab (GSK) is designed leverage LB-100’s synergistic enhancement of immune checkpoint blockade.

  • Status: Enrolled, with interim safety completed
  • Upcoming Milestone: Preliminary safety and efficacy data expected Q4 2025
  • Potential Market Impact: Global OCCC treatment market is projected to exceed $750 million by 2028 due to rising incidence and limited targeted therapies

1B/2 Trial – Advanced Soft Tissue Sarcoma (STS)

Soft tissue sarcomas are a diverse and difficult-to-treat group of cancers arising from connective tissues. For patients with advanced or metastatic disease, prognosis remains poor.
LIXTE’s Phase 1B/2 study evaluates LB-100 in combination with doxorubicin, the current standard of care, in patients with advanced STS.

  • Status: Dose escalation completed.
  • Upcoming Milestone: Safety report Q4 2025
  • Potential Market Impact: The global STS drug market is estimated to reach $2.1 billion by 2030, driven by the emergence of combination therapies and unmet medical need

1B Trial – Metastatic Microsatellite Stable (MSS) Colon Cancer

MSS colon cancer, representing roughly 85% of metastatic colorectal cancer (mCRC), remains unresponsive to checkpoint inhibitors.

LIXTE is conducting a Phase 1B trial assessing the safety and activity of LB-100 in combination with+ atezolizumab (Roche) (an ICI), seeking to overcome immune resistance in this cold tumor type.

  • Status: Trial open, first patients recruited
  • Potential Market Impact: The global colorectal cancer therapeutics market is expected to surpass $18 billion by 2030, with MSS disease representing the majority of treatment-resistant cases

Platform Potential and Market Opportunity

LIXTE’s strategy of targeting PP2A to potentiate multiple treatment modalities positions LB-100 as a versatile combination agent with broad applicability across solid tumors. The platform’s potential spans oncology subtypes with high unmet need, limited innovation, and growing incidence.

  • Strong IP Position: Multiple issued and pending patents covering composition, methods of use, and combinations
  • Pipeline Expansion: Additional tumor types and investigator-sponsored studies are under review, including glioblastoma.
  • Partnership Potential: Ongoing discussions with academic institutions and biopharma partners for co-development opportunities
