Brief Summary:

This is an open-label, non-controlled, multicenter, dose escalation, first-in-human phase I clinical trial with an expansion phase designed to assess the safety, tolerability, PK and PD parameters, and preliminary antitumor activity of intravenous dosing of PEP-010 as single agent and in combination with paclitaxel.

PEP-010 will be administered as single agent in patients with solid cancers who are not amenable to standard treatment, or in combination in patients who are eligible for the paclitaxel therapy.


Condition or disease Intervention/treatment Phase
Metastatic Solid Tumor Cancer Combination Product: Dose escalation, first-in-human phase I clinical trial with an Expansion phase Early Phase 1

Detailed Description:

PEP-010 will be administered on days 1, 2 and 3 every week. Treatment will be administered until disease progression, unacceptable toxicity, death or withdrawal of consent, whichever occurs first. Each cycle will be of 21 days duration.

The initial starting dose of PEP-010, DL1 is selected based on pre-clinical data at 0.15 mg/kg. The other doses per injection from DL2 to DL7 are 0.3, 0.6; 1.2; 2.5; 5 and 10 mg/kg.

For patients in Arm B, PEP-010 will be combined with Paclitaxel, at a dose of 80 mg/m², weekly until disease progression or unacceptable toxicity. Paclitaxel will be administered according to local guidelines.

Main objective for Dose escalation cohorts is to determine the maximum tolerated dose (MTD) and the recommended phase 2 dose (RP2D) of PEP-010 when administered as single agent (MTD1/RP2D1), and in combination with paclitaxel (MTD2/RP2D2) by recording the dose-limiting toxicities (DLTs).

Main objective for Expansion cohorts is to confirm the RP2Ds of PEP-010 as a single agent and/or in combination in patients with metastatic and/or recurrent cancer.

Secondary objectives are

  • To evaluate the safety and tolerability of PEP-010 when administered as single agent, and in combination with paclitaxel.
  • To assess the pharmacokinetics (PK) of PEP-010 as single agent, and in combination with paclitaxel in Dose escalation cohorts.
  • To assess the pharmacodynamic (PD) effects of PEP-010 as single agent, and in combination with paclitaxel.
  • To evaluate the preliminary antitumor activity of PEP-010 alone and in combination with paclitaxel, using Objective Response Rate (ORR), Progression-Free Survival (PFS) according to RECIST1.1, duration of response, and Overall Survival (OS).
  • To assess the immunogenicity of PEP-010 as single agent, and in combination with paclitaxel in Dose escalation cohorts.

Estimated Study Completion Date : December 31, 2023

Arm Intervention/treatment
Experimental: Arm A: PEP010 as single agent
In arm A, the dose escalation phase will use accelerated titration design (ATD) for the first 4 dose levels (0.15, 0.3, 0.6, 1.2 mg/kg), followed by 3+3 design
Combination Product: Dose escalation, first-in-human phase I clinical trial with an Expansion phase
PEP-010 will be administered on days 1, 2 and 3 every week, as a 3-hour intravenous infusion. Treatment will be administered until disease progression, unacceptable toxicity, death or withdrawal of consent, whichever occurs first. Each cycle will be of 21 days duration.

Experimental: Arm B: PEP010 in combination with paclitaxel.
In arm B, the dose escalation phase will begin with DL4 (1.2 mg/kg) and will follow a 3+3 design
Combination Product: Dose escalation, first-in-human phase I clinical trial with an Expansion phase
PEP-010 will be administered on days 1, 2 and 3 every week, as a 3-hour intravenous infusion. Treatment will be administered until disease progression, unacceptable toxicity, death or withdrawal of consent, whichever occurs first. Each cycle will be of 21 days duration.




Primary Outcome Measures :
  1. Rate of occurrence of dose-limiting toxicities (DLT) within cycle 1 (21 days) after initiation of the study treatment for both parts. [ Time Frame: 21 days after study treatment initiation ]
    The DLT is defined as any clinically significant non-hematological toxicity ≥ grade 3 and any hematological toxicity ≥ grade 4 of treatment-related adverse event

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

Part I and II, Arms A and B:

  1. Arm A: Patients must have histologically confirmed diagnosis of recurrent and/or metastatic solid tumors, who are not amenable to standard therapy, with exceptions as defined in the non-inclusion criteria,
  2. Arm B: Patients must have histologically confirmed diagnosis of recurrent and/or metastatic solid tumors. Patients must be eligible for a treatment with paclitaxel as single agent. Patients who are eligible for standard of care paclitaxel-based combination therapy should not be included in the trial, unless they have been previously exposed to that specific combination therapy. Specifically :

    • Patients with ovarian cancer must have received prior therapy with paclitaxel as part of standard of care in combination with carboplatin.
    • Patients with triple negative breast cancer are eligible for the trial since paclitaxel as single agent is standard of care in this disease.
  3. Age ≥ 18 years,
