Clinical Trial Summary

This is a Phase I, multi-center, Dose-Escalating, Safety Study of an Intravenously Administered Pegylated Liposomal Mitomycin-C Lipid-based Prodrug (PL-MLP, PROMITIL) in Cancer Patients with Solid Tumors. The study comprised of:

Escalated cohorts A-H: 27 male or female participants, ages 18-80, BMI 18-36 diagnosed with inoperable, recurrent or metastatic malignant solid tumors, deemed incurable, and who have failed to respond to standard therapy or for whom no standard therapy is available. Eligible subjects will be assigned, successively in order of accrual, to one of eight cohorts, to receive escalating doses of intravenously infused PROMITIL. PROMITIL will be administered as an intravenous infusion. Dose escalation will only proceed in the absence of dose-limiting toxicity (DLT). For this purpose, each cohort will only begin its first cycle of PROMITIL when the cohort preceding it has successfully completed its first 4-week cycle without any signs of DLT.

Expanded cohort: 17 adult patients with metastatic CRC. The purpose of this expanded cohort is to further evaluate the safety of Promitil and to search for signs of antitumor activity of Promitil in this specific patient population.

Combination Cohort (Promitil concomitantly with Capecitabine): 23 adult patients with metastatic CRC.

Triple combination Cohort: 13 additional subjects with metastatic CRC, received combination of Promitil concomitantly with Bevacizumab (5 mg/kg) on day 1 of a 28 day cycle and Capecitabine on days 1-14 of a 28 day cycle.

3 weekly cohort- 9 subjects with metastatic CRC will receive Promitil and Bevacizumab (7.5 mg/kg) on day 1 of a 21 day cycle.

Clinical Trial Description

For all cohorts, PROMITIL will be administered as an intravenous infusion at an initial rate of 0.25mg/min followed by gradual increase to a maximal rate of 2mg/min until completion of dosing, if absence of infusion reactions is established and in line with most updated version of IFU available for this study.

For each subject, subsequent dosing will take place 28 days after the previous treatment, provided they are deemed fit to be dosed again.

Patients will return to the study center on days 8, 15, 22 of cycle 1, and on day 15 of cycles 2 and 3, for monitoring assessments.

All patients will be followed-up for survival and post-Promitil treatment. Patients who did not received 3 cycles of PROMITIL will be followed up only until PD.

For the 3 weekly cohort Promitil will be administered at 3 week interval together with Bevacizumab (7.5 mg/kg). Patients will return to the study center on days 8 and 15 of cycle 1, and on day 15 of cycles 2 and 3, for monitoring assessments. ;
