Gemcitabine Plus Rapamycin Versus Gemcitabine to Treat Advanced Soft Tissue Sarcoma

October 26, 2015 updated by: Grupo Espanol de Investigacion en Sarcomas

Phase 1/2, Randomized, Multicenter, Prospective Study of Gemcitabine and Rapamycin (Sirolimus) Combination Versus Gemcitabine Only to Treat Advanced Soft Tissue Sarcoma

The soft tissue sarcomas (STS) constitute an infrequent group of malignant neoplasms of mesenchymal origin. In Spain, the approximate incidence is of 2 new cases per 100.000 inhabitants every year. In patients with metastatic STS, the average survival is very short, approximately 12 months. The systemic treatment of the metastatic disease has had a very limited development, with few satisfactory results. This facts reflect the urgent need to identify new active agents for treatment of these patients.

The molecular pathway of the serine/threonine kinase mammalian target of rapamycin (mTOR) plays a central role in the regulation of the proteins translation, cellular growth and metabolism (Meric-Bernstam F et al. 2009). Currently, the mTOR pathway is considered a relevant target for the development of anti-cancer drugs, as rapamycin. Preliminary results of some clinical trials suggest that mTOR inhibitors could have some clinical activity for different types of sarcoma, including STS (Chawla et al Proc.ASCO 2006; Schuetze et al. Proc.ASCO 2006).

Gemcitabine is a chemotherapy antimetabolite agent with a broad antitumoral spectrum. The activity of this drug to treat resistant sarcomas and its reduced toxicity make from gemcitabine an adequate candidate for its study in combination with new drugs addressed to molecular targets in the STS treatment.

Pre-clinical studies suggest that mTOR inhibitors could have a potential synergistic or additive effect with some chemotherapy agents. The combination of rapamycin and gemcitabine seems to be a reasonable strategy to explore for the STS treatment.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Description

Inclusion Criteria:

  1. Patients with anatomopathological diagnosis of metastatic or locally advanced unresectable soft tissue sarcoma (STS). Patients with the following STS types will be excluded: chondrosarcoma, Ewing's sarcoma and embryonal or alveolar rhabdomyosarcoma. In phase 1 it will be allowed to include patients having other types of advanced cancer which are resistant to the standard treatment and can benefit from any of the study drugs.
  2. Prior treatment with chemotherapy including doxorubicin and ifosfamide, or contraindication for its administration. The previous treatment with gemcitabine or inhibitors of mTOR is not allowed.
  3. Age ≥ 18 y ≤ 70 years.
  4. ECOG performance status: 0 - 1. In Phase 1 only patients with ECOG 0-1 will be enrolled.
  5. Disease measurable according to RECIST criteria. Proven relapsed disease.
  6. Adequate bone marrow function, defined as neutrophil count ≥ 1.500/mm^3 and platelets ≥ 100.000/mm^3.
  7. Adequate renal and hepatic function , defined as calculated creatinine clearance ≥ 60 ml/min, creatinine, total bilirubin, AST and/or ALT ≤ 1,5 times the upper limit of normal (ULN).
  8. Informed consent form signed by the patient prior to the beginning of the treatment.

Exclusion Criteria:

  1. History of previous cancer diagnosed or treated in the past 5 years except basal cell carcinoma, cervical carcinoma in situ or superficial bladder cancer.
  2. Presence of brain metastases.
