ECT-Pembrolizumab in Patients With Unresectable Melanoma With Superficial or Superficial and Visceral Metastases
Study Details
Study Description
Brief Summary
This is a Phase 2 multicenter, open label, non-randomized, interventional study enrolling 53 patients.The objectives and purposes of the clinical study described herein are to determine if concomitant Pembrolizumab (Keytruda) and ECT treatments are safe and able to improve local and systemic response rates.ECT will be performed with the CLINIPORATOR and a single IV dose of Bleomycin

Phase 2 |
Detailed Description
ECT induces immunogenic cell death of cancer cells with a more efficient antigen presentation of tumor-derived antigens by APCs to T-cells, particularly CD8+ antigen-specific T cells. Anti-PD-1 mAb reverts T-cell exhaustion induced by PD-1/PD-L1 and PD-L2 engagement on CD8+ T cells. Moreover, it may also be beneficial in the priming phase of the antitumor immune responses, inducing long-lived tumor antigen-specific CD8+ T-cell effectors.
The main hypothesis is to establish if concomitant treatment of Pembrolizumab and ECT is able to lead to a 20% increase of the ORR using as a reference the proportion of success available in the literature for Pembrolizumab.
The investigators will perform a proteomic analysis of sera of treated patients, collected before and after treatments, with particular emphasis on cytokines and chemokines, to evaluate possible markers associated with a better clinical outcome.

Outcome Measures
Primary Outcome Measures
- Overall Response rate, as Determined by RECIST v1.1 [Baseline up to disease progression or death due to any cause, whichever occurs first (up to approximately 60 months)]
CT scan
Eligibility Criteria
Criteria
Inclusion Criteria:
-
Have a histologically confirmed advanced melanoma stages III b/c or IV, with at least the following superficial lesions: 5 lesions if diameter < 1 cm or 3 lesions if diameter > 1 cm.
-
Could have received previous therapy included CT, antiCTLA4 or antiBRAF/antiMEK treatment or be treatment naïve.
-
Be willing and able to provide written informed consent/assent for the trial.
-
Be >= 18 years of age on day of signing informed consent.
-
Have measurable disease based on RECIST 1.1.
-
Be willing to provide tissue from a newly obtained core or excisional biopsy of a tumor lesion. Newly-obtained is defined as a specimen obtained up to 6 weeks (42 days) prior to initiation of treatment on Day 1. Subjects for whom newly-obtained samples cannot be provided (e.g. inaccessible or subject safety concern) may submit an archived specimen only upon agreement from the Sponsor.
-
Have a performance status ≤ 2 on the ECOG Performance Scale. (Ambulatory and capable of all self-care but unable to carry out any work activities. Up and about more than 50% of waking hours.)
-
Demonstrate adequate organ function as defined in
-
Have a baseline total body CT scan (brain MRI if brain metastasis are suspected)
-
Patients with brain metastasis are allowed to participate if previously treated and brain lesion stability or inactivity is demonstrated. Patients with a history of brain metastasis are required to have a pre-baseline brain MRI at least 60 days (2 months) before the Screening/Baseline visit (Visit 1) for comparison to the Screening (Visit 1) MRI. Patients for whom MRI is contraindicated will undergo head CT. Stable/inactive disease is determined by comparing the pre- baseline and screening/baseline MRI/CT results.
-
Patients presenting with brain metastasis at Screening/Baseline who had no known previous brain involvement and who had no brain MRI/CT tests at least 60 days (2 months) before Screening/Baseline are considered screening failures and will be excluded from study enrollment.
-
Have cutaneous or subcutaneous metastases from melanoma that are accessible for the application of electric pulses using the single use, sterile CLINIPORATOR™ electrodes (5 lesions if diameter <1 cm or 3 lesions if diameter >1 cm). For patients presenting with more than 7 lesions, the lesions with the largest diameters that fall within the <10 to 30 mm size requirements will be considered "target" lesions for RECIST criteria and study purposes. The others will be recorded and monitored but will not considered as Target.
-
Have lesions clearly requiring palliative treatment [e.g., symptomatic (bleeding, draining, painful), disfiguring or causing distress to the patient].
-
A treatment-free period of three (3) weeks before enrolling in the study. NOTE: Patients receiving concomitant treatments for unrelated existing pathologies are eligible for enrollment.
-
Life expectancy > 3 months.
-
Female subject of childbearing potential should have a negative urine or serum pregnancy within 72 hours prior to receiving the first dose of study medication. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required.
-
Female subjects of childbearing potential (Section 5.7.2) must be willing to use an adequate method of contraception as outlined in Section 5.7.2 - Contraception, for the course of the study through 120 days after the last dose of study medication. Note: Abstinence is acceptable if this is the usual lifestyle and preferred contraception for the subject.
-
Male subjects of childbearing potential (Section 5.7.1) must agree to use an adequate method of contraception as outlined in Section 5.7.1- Contraception, starting with the first dose of study therapy through 120 days after the last dose of study therapy. Note: Abstinence is acceptable if this is the usual lifestyle and preferred contraception for the subject.
Exclusion Criteria:
-

This should exclude adequately treated Stage 1 or Stage 2 basal/squamous cell carcinoma of the skin, carcinoma in situ of the cervix or breast, or other in situ cancers. Shorter intervals can be considered after discussion with Merck.
-
Has known active central nervous system (CNS) metastases and/or carcinomatous meningitis. Subjects with previously treated brain metastases may participate provided they are stable (without evidence of progression by imaging for at least four weeks prior to the first dose of trial treatment and any neurologic symptoms have returned to baseline), have no evidence of new or enlarging brain metastases, and are not using steroids for at least 14 days prior to trial treatment. This exception does not include carcinomatous meningitis which is excluded regardless of clinical stability.
