Brief Summary:
The purpose of this study is to test whether the addition of NT-I7 to atezolizumab provides clinically meaningful outcomes for patients with anti-PD-1/PD-L1 naive or relapsed/refractory high-risk melanoma, Merkel Cell Carcinoma (MCC) and cutaneous Squamous Cell Carcinoma (cSCC)

Condition or disease Intervention/treatment Phase
Melanoma Merkel Cell Carcinoma Cutaneous Squamous Cell Carcinoma Drug: NT-I7 Drug: atezolizumab Phase 1 Phase 2

Detailed Description:

This is a Phase 1b/2a, open-label, multicenter study to evaluate the safety, tolerability and anti-tumor effect of NT-I7 (rhIL-7-hyFc) in combination with atezolizumab (MPDL3280A, anti-PD-L1) in patients with anti-PD-1/PD-L1 naïve or relapsed/refractory high-risk skin cancers including cutaneous Squamous Cell Carcinoma (cSCC), Merkel Cell Carcinoma (MCC) and melanoma.

This study has been designed to evaluate the safety and tolerability, including the Maximum Tolerated Dose (MTD) or recommended Phase 2 dose (RP2D), of NT-I7 in combination with atezolizumab.

There are two phases to this study:

  • Phase 1b, a NT-I7 dose-escalation phase to determine the MTD or RP2D
  • Phase 2a, a non-randomized parallel dose expansion phase to confirm the MTD or RP2D in both arms.

Arm I: Anti-PD-1/PD-L1 (checkpoint inhibitors, CPI) naïve patients with cSCC and MCC

Arm II: Anti-PD-1/PD-L1 relapsed/refractory patients with cSCC, MCC and melanoma

Number of Patients A total of up to 84 patients will be enrolled; Up to 24 patients will be enrolled in the Phase 1b (up to 6 patients per dose level, using 3 + 3 design), and 60 patients will be enrolled in the Phase 2a (24 patients in Arm I, i.e., 12 patients for each indication, and 36 in Arm II, i.e., 12 patients for each indication).

  3. Preliminary assessment the Disease Control Rate (DCR) of NT-I7 in combination with atezolizumab [ Time Frame: Up to approximately 56 months ]
    To preliminarily assess the Disease Control Rate (DCR) defined as proportion of patients with a best overall response of CR, PR or stable disease (SD).

  4. Preliminary assessment the Duration of Objective Response (DOR) of NT-I7 in combination with atezolizumab [ Time Frame: Up to approximately 56 months ]
    To preliminarily assess the Duration of Objective Response (DOR), defined as the time from the first occurrence of a documented objective response to the time of the first documented disease progression or death from any cause, whichever occurs first, per RECIST v1.1 as determined by the investigator.

  5. Preliminary assessment the Progression Free Survival (PFS) of NT-I7 in combination with atezolizumab [ Time Frame: Up to approximately 56 months ]
    To preliminarily assess the Progression Free Survival (PFS), defined as the time from the first study treatment (Cycle 1 Day 1) to the first occurrence of progression or death from any cause, whichever occurs first, per RECIST v1.1 as determined by the investigator.
