Building a pipeline in multiple cancer indications
LIXTE is conducting multiple clinical trials with LB-100 in combination with chemotherapy and immunotherapy for solid tumors such as Ovarian Clear Cell Cancer, Metastatic Colon Cancer and Advanced Soft Tissue Sarcoma.

LB-100 + Immunotherapy
Ovarian Clear Cell Cancer
NCT06065462
Rationale
- Ovarian Clear Cell Cancer (OCCC) with acquired mutations reducing PP2A activity are more sensitive to immunotherapy
- If LB-100 pharmacologic inhibition of PP2A mimics the effect of mutational reduction in PP2A, LB-100 is expected to enhance immunotherapy in OCCC tumors that do not have mutation
Study Design
Phase 2
Ovarian Clear Cell Cancer (OCCC)
(NCT06065462)
A Phase 2 collaborative clinical trial to assess whether adding Lixte’s LB-100 to GSK’s programmed death receptor-1 (PD-1)-blocking monoclonal antibody, dostarlimab, may enhance the effectiveness of immunotherapy in the treatment of ovarian clear cell carcinoma (OCCC).
The clinical trial is sponsored by The University of Texas MD Anderson Cancer Center and will be conducted at MD Anderson and at Northwestern University’s Robert H. Lurie Comprehensive Cancer Center.
Aim is to enroll a total of 21 patients; patients will be treated up to 24 months or until disease progression.
LB-100 + Immunotherapy
Metastatic MSI Low Colon Cancer
NCT06012734
Rationale
- LB-100 stimulates T-Cell Proliferation
- LB-100 influences RNA splicing through unbiased phosphoproteomics
- Generates new antigens for immune stimulation
- Generates an MSI phenotype in MSS tumors
- Validated LB-100 + PD-1 in synergy in multiple pre-clinical models
Study Design
Phase 1b
Metastatic Colon Cancer, Micro Satellite Instable Low (MSI Low)
(NCT06012734)
Dr. Neeltje Steeghs, Medical Oncologist and colon cancer expert at the Netherlands Cancer Institute, is leading a Phase1b trial to test whether LB-100 in combination with Dostarlimab improves standard therapy of previously treated MSI Low Metastatic Colon Cancer.
The maximally tolerated dose of LB-100 will be established when added to standard immunotherapy and up to 36 patients will be treated.

LB-100 + Chemotherapy
Advanced Soft Tissue Sarcoma
NCT05809830
Rationale
- ASTS is also a highly aggressive cancer with no effective treatment
- A single drug, doxorubicin, has been the standard Rx for over 40 years
- In animal models of ASTS, LB-100 markedly improves the effectiveness of doxorubicin
- Phase II, Only patients with ASTS subtypes that progress on average within 4.5 months of starting treatment are entered
Study Design
Phase 2 Trial in
Advanced Soft Tissue Sarcoma (ASTS)
(NCT05809830)
Phase I: To define the safety of combining LB-100 with doxorubicin: one year of accrual.
Phase II: Untreated patients randomized to standard therapy with doxorubicin +/- LB-100 (maximum 150 patients) Readout: increased progression free survival from 4.5 to 7.5 months.
Multi-center study in collaboration with Grupo Español de Investigación en Sarcomas (GEIS) (PI: Javier Martín Broto MD, Madrid) (12 sites in Spain).
Study open, first patient entered in June 2023.
