## Brief Summary

This single center, Phase 1b, prospective, dose limiting toxicity (DLT)-clearing study, will assess the safety and efficacy of intravenously administered PROMITIL in combination with FOLFOX in cancer patients with inoperable, locally advanced or metastatic GI solid tumors.

Based on previous clinical results, we hypothesized that the addition of PROMITIL to FOLFOX, a treatment protocol consisting of oxaliplatin and fluoropyrimidine and commonly used to treat gastrointestinal (GI) malignancies, may enhance the overall efficacy of this combination regimen while maintain a reasonable safety profile.

## Detailed Description

Each patient will undergo screening, conducted up to 21 days before start of treatment, and receive 3 cycles of PROMITIL treatment, administered at four-week intervals, in combination with FOLFOX, administered at two-week intervals. Thereafter, patients may continue treatment with FOLFOX only, or with another regime at the investigator's discretion and will be followed up until death. Patients will be successively assigned, in order of accrual, to be concomitantly treated with PROMITIL and FOLFOX, at doses of PROMITIL meant to clear a dose of this combination treatment from DLT. Six patients will be treated with an initial DLT-clearing dose (Cohort 1). PROMITIL dose escalation from Cohort 1 to Cohort 2 will be authorized after 5 or 6 Cohort 1 patients complete their first two cycles of combination treatment with up to 1 DLT event reported for all 6 treated patients. If 2 or more Cohort 1 patients suffer from a DLT event in the first two cycles of treatment, 6 patients will be enrolled to Cohort -1 and treated with one dose level lower of PROMITIL. If 2 or more DLT events occur in Cohorts 2 or -1, the study will be discontinued for these patients and only patients in Cohort 1 will complete the study as planned. In any case, the total number of evaluable patients in the DLT-clearing phase will be no more than 12.

## Eligibility

## Arms

- **Promitil 1.6 mg/kg** (EXPERIMENTAL) — PROMITIL (1.6 mg/kg body weight) will be intravenously (IV) administered on the first day of three 28-day cycles. On days 1 and 15 of each PROMITIL cycle, patients will be treated with the mFOLFOX6 regimen, which includes concurrent treatment with oxaliplatin 85 mg/m2 IV and leucovorin 200 mg/m2 IV, immediately followed by 5-FU 400 mg/m2 IV bolus, and then continuous infusion of 5-FU 1200 mg/m2/day, for 2 days (46-48 h
- **Promitil 2.0 mg/kg** (EXPERIMENTAL) — PROMITIL (2.0 mg/kg body weight) will be intravenously (IV) administered on the first day of three 28-day cycles. On days 1 and 15 of each PROMITIL cycle, patients will be treated with the mFOLFOX6 regimen, which includes concurrent treatment with oxaliplatin 85 mg/m2 IV and leucovorin 200 mg/m2 IV, immediately followed by 5-FU 400 mg/m2 IV bolus, and then continuous infusion of 5-FU 1200 mg/m2/day, for 2 days (46-48 h

## Interventions

- **Promitil** (DRUG) — The first 6 patients recruited to the study will receive 1.6 mg/kg Promitil. Dose escalation to cohort 2 (PROMITIL dose of 2mg/kg) will be authorized after 5 or 6 patients of cohort 1 have completed the second cycle with DLT detected in fewer than two patients. If ≥2 patients of Cohort 1 develop DLT, dose escalation will be halted and Cohort -1 (PROMITIL dose of 1.2 mg/kg) will be opened. Should ≥2 patients in Cohort -1 or Cohort 2 experience DLT events, the study will be discontinued. In parallel, on days 1 and 15 of each cycle, patients will be treated with the mFOLFOX6 regime, which involves concurrent treatment with oxaliplatin 85 mg/m2 IV and leucovorin 200 mg/m2 IV, immediately followed by 5-FU 400 mg/m2 IV bolus, and then continuous infusion of 5-FU 1200 mg/m2/day, for 2 days (46-48 h).
