A Phase I Trial of Combination Gemcitabine and Nab-Sirolimus in Advanced Leiomyosarcomas or Advanced Soft-Tissue Sarcomas With TSC2 or TSC1 Loss-of-function Mutations or Deletions
Trial Parameters
Brief Summary
To find a recommended dose of gemcitabine and nab-sirolimus that can be given in combination to participants with advanced leiomyosarcomas or soft-tissue sarcomas.
Eligibility Criteria
Inclusion Criteria: 1. Patients must have histologically confirmed leiomyosarcoma or sarcoma with TSC2 or TSC1 loss-of-function mutations or deletions based on standard-of-care genomic testing. 2. Sarcoma that is metastatic or unresectable and for which standard curative measures do not exist or are no longer effective. One prior standard systemic therapy is required for leiomyosarcoma (LMS) Patients. 3. Prior gemcitabine-based chemotherapy is allowed if the last dose of gemcitabine was given more than 12 months prior to the first dose of treatment on trial, there was no progression of disease while on treatment with gemcitabine, and there was intolerable toxicity. 4. Patients must have measurable disease, defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded for non-nodal lesions and short axis for nodal lesions) as ≥20 mm (≥2 cm) by chest x-ray or as ≥10 mm (≥1 cm) with CT scan, MRI, or calipers by clinical exam. 5.
