Brief Summary:
Open-label, single-arm, multi-center, Phase IIa study to evaluate the efficacy, safety, and immunological response of OBP 301 in patients with unresectable/unresected metastatic melanoma. This proof of concept study will be undertaken in male and female patients with unresectable Stage III and IV melanoma. Patients with unresectable/unresected mucosal melanoma may be enrolled after consultation with the Medical Monitor.

Condition or disease Intervention/treatment Phase
Melanoma Stage III Melanoma Stage Iv Drug: OBP-301 Phase 2

Detailed Description:

Primary Objective:

The primary objective of this study is to evaluate the overall tumor sites response (objective response rate [ORR]) to OBP-301 in both injected and noninjected lesions up to and including Week 24 in patients with unresectable/unresected Stage III and IV melanoma. The ORR is defined as the rate of complete response (CR) and partial response (PR) based on the modified immune-related response criteria (irRC) 1.0. The modification is to allow the identification of up to 10 cutaneous, subcutaneous, and/or lymph node tumor lesions and identify the lesions as target and nontarget lesions.

Secondary Objectives:

  • To evaluate the ORR up to and including Week 24 in injected target lesions based on the modified irRC 1.0 and Response Evaluation Criteria in Solid Tumors (RECIST) 1.1
  • To evaluate the ORR up to and including Week 24 in noninjected target lesions based on modified irRC 1.0 and RECIST 1.1
  • To evaluate the ORR in both injected and noninjected target lesions at Week 12 based on the modified irRC 1.0 and RECIST 1.1
  • To evaluate duration of response and time to response
  • To evaluate progression free survival (PFS) at Week 24 and Week 48
  • To evaluate overall survival (OS) at Week 24 and Week 48
  • To evaluate the safety of OBP 301

Exploratory Objective (optional):

The optional exploratory objective of this study is to investigate the tumor immunological response in blood and tumor tissue following treatment with OBP-301.

  3. Time to Treatment Response from start date to end date [ Time Frame: Week 24 and Week 48 ]
    Time to Treatment Response (TTR): the start date is the date of first treatment (Injection 1, Day 1) and the end date is the date of first documented response (CR or PR).

  4. Duration of response of injected and noninjected lesions [ Time Frame: Week 24 and Week 48 ]
    Duration of response (injected and noninjected lesions): applies only to patients whose best overall response is CR or PR. The start date is the date of first documented response (CR or PR) and the end date is the date of first documented disease progression or the date of death due to underlying cancer.

  5. Progression Free Survival at weeks 24 and 48 [ Time Frame: Week 24 and Week 48 ]
    PFS at Week 24 and Week 48

  6. Overall Survival at weeks 24 and 48 [ Time Frame: Week 24 and Week 48 ]
    OS at Week 24 and Week 48

  7. Safety of OBP-301 as assessed by incidence of AEs and SAEs [ Time Frame: Through study completion ]
    Incidence of AEs and serious adverse events (SAEs) as assessed by the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE; version 4.03). Changes in clinical laboratory parameters (serum chemistry, coagulation parameters, hematology, urinalysis) from Baseline.Vital signs. Physical examination. Electrocardiogram (ECG).

  8. Safety of OBP-301 as assessed by changes in clinical laboratory parameters [ Time Frame: Through study completion ]
    Changes in clinical laboratory parameters (serum chemistry, coagulation parameters, hematology, urinalysis) from Baseline.


Other Outcome Measures:
  1. Exploratory Analysis (optional) [ Time Frame: Through study completion ]
    Local and systemic immunological response
