Brief Summary:
This phase II trial studies the effect of pembrolizumab alone or in combination with CMP-001 in treating patients with melanoma that can be treated by surgery (operable). Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Immunotherapy with CMP-001 may induce changes in body's immune system and may interfere with the ability of tumor cells to grow and spread. The addition of CMP-001 to pembrolizumab could improve the ability of the immune system to shrink tumors and to prevent them from returning.

Detailed Description:

PRIMARY OBJECTIVE:

I. To evaluate the rate of pathologic complete response (pCR) rate in patients in each arm of the trial.

SECONDARY OBJECTIVES:

I. To evaluate the rate of pathologic near-complete/major response (pMR) of the neoadjuvant therapy in each arm.

II. To evaluate the pathologic response rate of un-injected lesions on the combination arm.

III. To evaluate relapse-free survival (RFS) in each arm. IV. To evaluate overall survival (OS) in each arm. V. To evaluate the preoperative radiographic response rate in each arm. VI. To evaluate safety and toxicity of neoadjuvant therapy in each arm.

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM A:

NEOADJUVANT PHASE: Patients receive pembrolizumab intravenously (IV) over 30 minutes on day 1. Treatment repeats every 21 days for up to 3 cycles in the absence of disease progression or unacceptable toxicity.

SURGERY: Patients undergo surgery 1-2 weeks after completion of neoadjuvant phase.

ADJUVANT PHASE: After recovery from surgery, patients receive pembrolizumab IV over 30 minutes on day 1 of every other cycle. Treatment repeats every 21 days for up to 16 cycles in the absence of disease progression or unacceptable toxicity.

ARM B:

NEOADJUVANT PHASE: Patients receive VLP-encapsulated TLR9 agonist CMP-001 (CMP-001) subcutaneously (SC) on day 1 of cycle 1 and then intratumorally on days 8 and 15 of cycle 1, days 1, 8, and 15 of cycle 2, and day 1 of cycle 3. Patients also receive pembrolizumab IV over 30 minutes on day 8 of each cycle. Treatment repeats every 21 days for up to 3 cycles in the absence of disease progression or unacceptable toxicity.

SURGERY: Patients undergo surgery 1-2 weeks after completion of neoadjuvant phase.

ADJUVANT PHASE: After recovery from surgery, patients receive pembrolizumab IV over 30 minutes on day 1 of every other cycle. Treatment repeats every 21 days for up to 16 cycles in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 30 days and then every 3 months if < 2 years from study entry, every 6 months if 2-5 years from study entry, and every 12 months if > 5 years from study entry for up to 10 years (15 years total follow up).

Secondary Outcome Measures :
  1. Radiographic response rate [ Time Frame: Up to 15 years ]
    Will be assessed using RECIST.

  2. Relapse-free survival [ Time Frame: From randomization to relapse or death (whichever occurs first), assessed up to 15 years ]

  4. Incidence of adverse events [ Time Frame: Up to 30 days after the last study drug administration ]

Exclusion Criteria:

  • Patient must not have received any live vaccine within 30 days prior to randomization and while participating in the study. Live vaccines include, but are not limited to, the following: measles, mumps, rubella, chicken pox, yellow fever, rabies, Bacillus Calmette-Guerin (BCG), and typhoid (oral) vaccine. Patients are permitted to receive inactivated vaccines and any non-live vaccines including those for the seasonal influenza and COVID-19 (Note: intranasal influenza vaccines, such as Flu-Mist are live attenuated vaccines and are not allowed). If possible, it is recommended to separate study drug administration from vaccine administration by about a week (primarily, in order to minimize an overlap of adverse events)

A urine or serum pregnancy test must be repeated within 72 hours prior to receiving the first dose of pembrolizumab if the test done for eligibility/randomization is done outside of this 72 hour window. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required. A patient of childbearing potential is defined as anyone, regardless of sexual orientation or whether they have undergone tubal ligation, who meets the following criteria: 1) has achieved menarche at some point, 2) has not undergone a hysterectomy or bilateral oophorectomy; or 3) has not been naturally postmenopausal (amenorrhea following cancer therapy does not rule out childbearing potential) for at least 24 consecutive months (i.e., has had menses at any time in the preceding 24 consecutive months)

    • Patients who require topical, ophthalmologic and inhalational steroids are permitted to enroll
    • Patients with hypothyroidism who are stable on hormone replacement are permitted to enroll
    • Patients who require active immunosuppression with corticosteroids at a dose of prednisone > 5 mg daily (or equivalent) for any reason are ineligible
    • Patients with adrenal insufficiency are ineligible
    • Patients who have developed autoimmune disorders of grade 4 while on prior immunotherapy are not permitted to enroll on this study. Patients who developed autoimmune disorders of grade =< 3 may enroll if the disorder has resolved to grade =< 1 and the patient has been off systemic corticosteroids at doses > 5 mg for at least 2 weeks prior to randomization
  • Patients with a history of brain metastases are not eligible for this study as they do not meet the eligibility staging criteria
  • Patient must not have had an allogeneic tissue/solid organ transplant
  • Patient must not have a history of (non-infectious) pneumonitis that required steroids or current pneumonitis
