Arm Intervention/treatment
Experimental: Neoadjuvant Treatment

Neoadjuvant Phase: (3 x 4-week cycles, total 12 weeks): At every cycle, intratumoral tavo-EP will be administered (on Days 1 and 8) concurrently with 480 mg nivolumab IV infusion on Day 8 of each cycle (tavo-EP will be administered prior to nivolumab infusion).

Definitive Surgery Phase: Surgery may be scheduled about 2-4 weeks after the last dose of nivolumab following radiologic and clinical assessment at that point. Pathologic response will be determined by institutional pathologist.

Adjuvant Phase: Adjuvant therapy with nivolumab monotherapy will begin approximately 2-4 weeks following definitive surgery; recovery from surgery is required (Day 1 of Cycle 4 will be determined by the treating investigator once the subject is cleared to initiate systemic therapy). Nivolumab (480 mg IV infusion on Day 1 of each 4-week cycle) will be administered for up to 9 cycles during the Adjuvant phase.

Drug: Tavo
Tavo will be injected on Days 1 and 8 every 4 weeks at a dose volume of ¼ of the calculated lesion volume with a minimum dose volume per lesion of 0.1 mL for lesions of volume <0.4 cm3

Drug: Nivolumab
Nivolumab will be administered 480 mg every 4 weeks over 30 minute infusions

Device: OncoSec Medical Electroporation Therapy System

The OMS (OncoSec Medical Electroporation Therapy System), a medical EP device system, consists of 3 components: 1. an Electroporation Generator that generates electric pulses, 2. a sterile Applicator Tip containing needle array, and 3. an Applicator Handle that connects to the Electroporation Generator at the proximal end and connects to the Applicator Tip at the distal end.

Upon user activation of the attached Foot Switch, the OMS Electroporation Generator delivers controlled electrical pulses in a square wave pulse pattern yielding optimal transmembrane potential for electroporation to occur. EP pulses occur between 6 hexagonal opposing needle electrodes. After the first pulse, the polarity between the opposing needle electrode pairs is reversed and the needle pair is pulsed again. After the initial paired pulse, the pulse delivery is rotated clockwise to the next opposing needle pairs until a total of 6 pulses are delivered to complete the EP sequence.

Other Name: Electroporation




Primary Outcome Measures :
  1. Pathological Complete Response [ Time Frame: Up to 16 weeks after start of therapy ]
    Pathological Complete Response will be will be estimated based on the proportion of participants with no viable tumor on histologic assessment at definitive surgery after the 12 week Neoadjuvant phase. Surgery will then be scheduled 2-4 weeks after neoadjuvant phase.


Secondary Outcome Measures :
  1. Objective Response Rate [ Time Frame: 12 weeks after start of therapy ]
    ORR assessed by Investigator based on RECIST v1.1 at 12 weeks during the Neoadjuvant phase

  2. Relapse Free Survival [ Time Frame: 12 weeks after start of therapy ]
    RSF assessed by Investigator based on RECIST v1.1 at 12 weeks during the Neoadjuvant phase

  3. Overall Survival [ Time Frame: Up to 5 years after start of therapy ]
    Overall survival at 5 years after start of therapy

  4. Incidence of Treatment-Emergent Adverse Events [Safety and Tolerability] [ Time Frame: Up to 5 years after start of therapy ]
    To determine the safety and tolerability of combined treatment as neoadjuvant therapy will be based on the frequency of AEs

  5. Risk of Surgical Delay [ Time Frame: Up to 16 weeks after start or therapy ]
    Definitive surgery will be planned at about 12 weeks. Participants will be monitored for surgical delay (either due to toxicity and/or tumor progression).

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

Inclusion Criteria:

  • Participant must be ≥ 18 years of age inclusive, at the time of signing the informed consent
  • Histologic diagnosis of melanoma
  • Must be considered surgically operable and may present as any of the following groups:

    1. Primary melanoma with clinically apparent regional lymph node metastases, confirmed by pathological diagnosis.
    2. Clinically detected recurrence of melanoma at regional lymph node basin(s), confirmed by pathological diagnosis.
    3. Clinically or histologically detected primary melanoma involving multiple regional nodal groups, confirmed by pathological diagnosis.
    4. Clinically detected single site of nodal metastatic melanoma arising from an unknown primary, confirmed by pathological diagnosis.
    5. Participants with in transit or satellite metastases with or without lymph node involvement are allowed if they are considered surgically resectable at Screening by the treating surgical oncologist.
    6. Participants with distant cutaneous/subcutaneous, soft tissue or nodal metastases with or without regional lymph node involvement are allowed if they are considered potentially surgically resectable and can be biopsied at Screening by the treating surgical oncologist. Elevated LDH is not an exclusion.
  • Participants are eligible for this study either at presentation for primary melanoma with concurrent regional nodal and/or in-transit or distant metastasis, or at the time of clinically detected nodal, in transit, or distant recurrence
  • Participants must be evaluated by standard-of-care full body imaging studies including positron emission tomography - computed tomography (PET-CT ;preferred; including diagnostic CT component if possible) or CT (if PET-CT cannot be done) as well as magnetic resonance imaging (MRI) of the brain (or CT if MRI cannot be done) as part of the initial clinical work-up at Screening (no more than 4 weeks prior to Cycle 1, Day 1).
  • Have measurable disease based on RECIST v1.1, with at least one anatomically distinct lesion. Lesion or lesions must meet all the following baseline criteria:

    1. Accessible for electroporation
    2. Must be measured in at least one dimension (longest diameter in the plane of measurement is to be recorded)
    3. Greater than 3 mm
