Descriptive Information

• Brief Title: PV-10 vs Chemotherapy or Oncolytic Viral Therapy for Treatment of Locally Advanced Cutaneous Melanoma
• Official Title: PV-10 Intralesional Injection vs Systemic Chemotherapy or Oncolytic Viral Therapy for Treatment of Locally Advanced Cutaneous Melanoma
• Brief Summary: This is an international multicenter, open-label, randomized controlled trial (RCT) of single-agent intralesional PV-10 versus systemic chemotherapy or intralesional oncolytic viral therapy to assess treatment of locally advanced cutaneous melanoma in patients who (1) are not candidates for targeted therapy and (2) are not candidates for an immune checkpoint inhibitor. Subjects in the comparator arm will receive the Investigator's choice of dacarbazine (DTIC), temozolomide (TMZ) or intralesional talimogene laherparepvec as determined by Investigator preference and standard of care in the Investigator's country or region. Effectiveness will be assessed by comparison of progression-free survival (PFS) between all intent-to-treat (ITT) subjects in the two study treatment arms.

Detailed Description

Subjects will be randomized using a 2:1 treatment allocation (i.e. two-thirds of the subjects will receive PV-10).

Subjects in the comparator arm who have completed at least 1 cycle of study treatment and who meet the study protocol definition of disease progression but do not have evidence of visceral metastases will be eligible to enter the crossover portion of the study and receive PV-10. Subjects crossing over must meet all study inclusion and exclusion criteria for clinical laboratories, thyroid function, concurrent or intercurrent illness and pregnancy at the time of crossover.

Assessment of progression will be performed by an Independent Review Committee (IRC) based on Response Evaluation Criteria in Solid Tumors (RECIST) ver. 1.1 criteria. Events signaling progression include increase in size and/or number of lesions, distant or nodal disease progression, or death. All secondary endpoints involving disease response and progression will be based on the IRC determination.

An interim assessment of efficacy and safety will be performed by the IRC when 50% of the events required for the primary endpoint have occurred.

• Study Type: Interventional
• Study Phase: Phase 3

Study Design

Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single (Outcomes Assessor)
Masking Description:

Blinded review by independent review committee (IRC) for primary and key secondary endpoints.

Primary Purpose: Treatment

• Condition: Cutaneous Melanoma

Intervention

• Drug: PV-10 (10% rose bengal disodium)
• Drug: Dacarbazine, temozolomide or talimogene laherparepvec

Study Arms

• Experimental: PV-10
  Subjects will receive intralesional PV-10 to all Study Lesions on study Day 1. PV-10 should be re-administered at 28-day intervals until complete response, disease progression or study termination occurs.
  Intervention: Drug: PV-10 (10% rose bengal disodium)
• Active Comparator: Chemotherapy or Oncolytic Viral Therapy
  Subjects will receive (a) dacarbazine (intravenously at 850 m/m2) or temozolomide (orally at 200 mg/m2 daily for 5 consecutive days), administered at consecutive 28-day intervals, or (b) intralesional talimogene laherparepvec administered on an initial 21 interval followed by consecutive 14 day intervals, until complete response, disease progression or study termination occurs.
  Intervention: Drug: Dacarbazine, temozolomide or talimogene laherparepvec
