Melanoma Clinical Trial
Rigosertib Plus Pembrolizumab in Treating Patients With Unresectable/Metastatic Melanoma Refractory to PD-1 Inhibitors
This phase II clinical trial tests how well rigosertib plus pembrolizumab workings in treating patients with melanoma which cannot be removed by surgery (unresectable) or that has spread from where it first started (primary site) to other places in the body (metastatic), and that has not responded to previous treatment with PD-1 or PD-L1 inhibitors (refractory). Rigosertib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and may change the immune system to make immunotherapy more effective. 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. Giving rigosertib in combination with pembrolizumab may be more effective in treating patients with unresectable metastatic melanoma that has not responded to previous treatment with PD-1 or PD-L1 inhibitors than giving either drug alone.
I. To determine the efficacy of rigosertib plus pembrolizumab in patients with metastatic melanoma who are refractory to treatment with a PD-1 inhibitor.
I. To evaluate progression-free survival (PFS) in patients with PD-1 inhibitor refractory metastatic melanoma receiving rigosertib plus pembrolizumab.
II. To evaluate safety, tolerability and adverse event profile of rigosertib plus pembrolizumab in patients with PD-1 inhibitor refractory metastatic melanoma.
III. To evaluate overall survival (OS) in patients with PD-1 inhibitor refractory metastatic melanoma receiving rigosertib plus pembrolizumab.
I. To evaluate change in tumor-infiltrating lymphocytes (TILs) upon treatment with rigosertib plus pembrolizumab in patients with metastatic melanoma that is refractory to PD-1 inhibitor.
Patients receive rigosertib orally (PO) plus pembrolizumab intravenously (IV) throughout the study. Patients undergo computed tomography (CT) or magnetic resonance imaging (MRI) and blood sample collection at screening and on study, and may also undergo tissue biopsy at screening and on study.
Male/female participants who are at least 18 years of age on the day of signing informed consent with histologically confirmed diagnosis of unresectable or metastatic cutaneous melanoma will be enrolled in this study.
Male participants: A male participant must agree to use a contraception during the treatment period and for at least 6 days (140 hours) plus an additional 90 days (a spermatogenesis cycle) after the last dose of study treatment and refrain from donating sperm during this period.
Female participants: A female participant is eligible to participate if she is not pregnant, not breastfeeding, and at least one of the following conditions applies:
Not a woman of childbearing potential (WOCBP) OR
A WOCBP who agrees to follow the contractive guidance during the treatment period and for at least 6 days (140 hours) plus 120 days after the last treatment dose of study.
Participants must have progressed on treatment with an anti-PD-1/L1 monoclonal antibody (mAb) administered either as monotherapy or in combination with other checkpoint inhibitors or other therapies. PD-1 inhibitor treatment progression is defined by meeting the following criteria:
For patients treated with anti-PD-1/L1 mAb in the unresectable/metastatic setting:
Has received at least 2 doses of an approved anti-PD-1/L1 mAb.
Has demonstrated disease progression after anti-PD-1/L1 as defined by Immune-Modified Response Evaluation Criteria in Solid Tumors (iRECIST). The initial evidence of progressive disease (PD) is to be confirmed by a second assessment no less than 4 weeks from the date of the first documented disease progression, in the absence of rapid clinical progression.
Progressive disease has been documented within 12 weeks from the last dose of anti-PD-1/L1 mAb.
For patients treated with anti-PD-1/L1 mAb in the adjuvant setting:
Has received at least 2 doses of an approved anti-PD-1/L1 mAb.
Develops recurrent disease during active adjuvant treatment with anti-PD-1/L1 mAb, OR
Develops recurrent disease within 6 weeks of last dose of anti-PD-1/L1 mAb.
Progressive disease is determined according to iRECIST (ie, progression by Response Evaluation Criteria in Solid Tumors [RECIST] version [v]1.1 on first imaging, confirmed with repeat imaging performed at least 4 weeks later). Once disease progression is confirmed, the initial date of disease progression documentation will be considered the date of disease progression OR
The determination of clinical progression is made by the investigator.
Participants whose disease harbors BRAF V600 mutation must have been exposed to BRAF-targeted therapy, with BRAF-targeted treatment discontinued for either progressive disease or intolerable toxicity.
The participant (or legally acceptable representative if applicable) provides written informed consent for the trial.

Formalin-fixed, paraffin embedded (FFPE) tissue blocks are preferred to slides. Newly obtained biopsies are preferred to archived tissue.
