Clinical Trial Summary

Refractory soft tissue sarcoma remains a difficult malignancy to treat. The mammalian target of rapamycin (mTOR) is an enzyme that plays an important role in cancer cell survival. mTOR inhibitors, like temsirolimus, have shown activity in sarcoma. Irinotecan is a chemotherapy drug that has also been used to treat sarcoma. However, it is unknown whether combining these two drugs would result in improved efficacy with acceptable toxicity.

Therefore, the goal of this phase I study is to determine the maximum tolerated dose (MTD) and toxicity profile of combination temsirolimus and irinotecan both administered intravenously on a weekly basis to refractory soft tissue sarcoma patients.

Description:

Mammalian target of rapamycin (mTOR) inhibitors are anti-neoplastic agents with a wide potential range of clinical applications. The topoisomerase I inhibitor irinotecan is a potent DNA damaging drug. mTOR appears to enhance cancer cell survival following DNA damage, so it's reasonable to expect that mTOR inhibition combined with irinotecan may result in synergistic activity.

This is a single arm, non-randomized phase I trial of temsirolimus (an mTOR inhibitor) and irinotecan (a topoisomerase I inhibitor) in refractory soft tissue sarcoma patients. Successive groups of three patients will be entered at escalating dose levels. Irinotecan and temsirolimus will be administered weekly for three weeks followed by one week of rest. One course will therefore be four weeks. No intra-patient dose escalation will be allowed. Each patient will be treated until disease progression or intolerable side effects develop. Dose limiting toxicities will be assessed and the maximum tolerated dose will be reported.

Note that this trial was originally designed as a phase I/II study, but only the phase I portion was completed and will be reported.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Maximum Tolerated Dose (MTD) of Irinotecan	The MTD is the dose preceding that at which at least 2 out of 3 patients in the treatment group experience a dose limiting toxicity (DLT). DLT is defined as grade 3 neutropenia on retreatment day, a grade 4 febrile neutropenia, a drug-related grade 3 or 4 non-hematologic toxicity (except fatigue, nausea, vomiting or grade 3 hypersensitivity reaction) or a grade 2 or greater motor or sensory neuropathy	Up to 1 month	Yes
Primary	Maximum Tolerated Dose (MTD) of Temsirolimus	The MTD is the dose preceding that at which at least 2 out of 3 patients in the treatment group experience a dose limiting toxicity (DLT).
