About
This phase 1/2 trial will be conducted in two parts. Part 1 (Dose Selection) is designed to find the dose of dapansutrile with acceptable tolerability in combination with pembrolizumab. Part 1 will consist of up to 2 dose selection cohorts to evaluate the safety and tolerability of dapansutrile + pembrolizumab in patients with PD-1 resistant melanoma to find the recommended part 2 dose (RP2D). Part 1 will include a lead-in phase of dapansutrile monotherapy at 500 mg PO BID. At day 15, combination therapy with pembrolizumab will be initiated. Dose escalation is planned to a maximum of 1000 mg BID of dapansutrile + pembrolizumab.
Part 2 (Dose Expansion) is designed to assess preliminary efficacy of dapansutrile + pembrolizumab in PD-1 resistant melanoma. Once all patients in Part 1 have completed 4 weeks of dapansutrile therapy, the expansion phase will start enrolling. Part 2 will also include a 14-day lead-in period of dapansutrile monotherapy at the RP2D.

Inclusion criteria
Has histologically or cytologically confirmed melanoma.
Has unresectable Stage III or Stage IV melanoma, per AJCC 8th Edition Staging Criteria, not amenable to local therapy.
Male or female participants who are at least 18 years of age on the day of signing informed consent
Male participants must agree to use a reliable method of contraception (refer to Section 6.4.1) during the treatment period and for at least 120 days after the last dose of study drug and must refrain from donating sperm during this period.
Female participants must not be pregnant or breast feeding and meet at least one of the following conditions:
Participants must have received an anti-PD-1/PD-L1 mAb as part of their most recent line of therapy prior to enrollment in the study.
Participants must have progressed on or after treatment with an anti-PD-1/PD-L1 mAb administered either as monotherapy or in combination with other checkpoint inhibitors or other therapies in their most recent line of therapy. PD 1 treatment progression is defined by meeting all of the following criteria:
i. Progressive disease must be determined according to iRECIST ii. This determination is made by the investigator. Once PD is confirmed, the initial date of PD documentation will be considered the date of disease progression.
d. Patients who progress while receiving or within 6 months of receiving the last dose of anti-PD-1/L1 mAb in the neoadjuvant or adjuvant setting will be included. Inclusion of patients who progress within 6 months of stopping neoadjuvant or adjuvant anti-PD-1/L1 mAb will be capped at 20% of the total study population. Inclusion of patients who progress while still receiving neoadjuvant or adjuvant anti-PD-1/L1 mAB will not be capped.
The participant provides written informed consent for the trial
Measurable disease based on RECIST v.1.1. Lesions situated in a previously irradiated area are considered measurable if progression has been demonstrated in such lesions
Have available archival tumor tissue sample or newly obtained core or excisional biopsy of a tumor lesion. Formalin-fixed, paraffin embedded (FFPE) tissue blocks are preferred to slides.
Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1 or 2. Evaluation of ECOG must be performed within 7 days prior to C1D1.
Adequate organ function as defined below. Specimens must have been collected within 7 days prior to the start of study treatment:
Prior adverse events from anticancer therapy must be resolved to ≤ grade 1, with the exception of alopecia or endocrinopathies, which may be on replacement therapy. Prednisone equivalent of ≤ 10 mg is allowed.
Exclusion criteria
Ocular or mucosal melanoma
A WOCBP who is pregnant or breastfeeding or has a positive pregnancy test within 72 hours prior to receiving study treatment
Has received prior systemic anti-cancer therapy including investigational agents within 4 weeks prior to starting study treatment
Has received prior radiotherapy within 2 weeks of start of study intervention. Participants must have recovered from all radiation-related toxicities, not require corticosteroids, and not have had radiation pneumonitis. A 1-week washout is permitted for palliative radiation (≤2 weeks of radiotherapy) to non-CNS disease
Has received cytotoxic chemotherapy for melanoma at any point prior to study enrollment
Is currently participating in or has participated in a study of an investigational agent or has used an investigational device within 4 weeks prior to the first dose of study intervention
Has received an additional line of therapy after the PD-1/PD-L1 therapy prior to starting on this study.
Diagnosis of immunodeficiency or is receiving chronic systemic steroid therapy (in dosing exceeding 10 mg daily of prednisone equivalent) or any other form of immunosuppressive therapy within 14 days prior to the first dose of study drug
History of a second malignancy, unless potentially curative treatment has been completed with no evidence of malignancy for 2 years
a. Exception: time requirement does not apply to patients who underwent successful definitive resection of basal cell carcinoma of the skin, squamous cell carcinoma of the skin, superficial bladder cancer, in situ cervical cancer, or other in situ cancers
Known active CNS metastases and/or carcinomatous meningitis. Participants with previously treated brain metastases may participate, provided the patient is clinically stable and without requirement of steroid treatment for at least 14 days prior to first dose of study intervention
Severe hypersensitivity (≥Grade 3) to pembrolizumab and/or any of its excipients
Active autoimmune disease that has required systemic treatment in the past 2 years (i.e., with use of disease modifying agents, corticosteroids or immunosuppressive drugs). Replacement therapy (eg., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment and is allowed
History of (non-infectious) pneumonitis/ interstitial lung disease that required steroids or has current pneumonitis/ interstitial lung disease
Active infection requiring systemic therapy
Known history of Human Immunodeficiency Virus (HIV) infection
Known history of Hepatitis B (defined as Hepatitis B surface antigen [HBsAg] reactive) or known active Hepatitis C virus (defined as HCV RNA [qualitative] is detected) infection. Note: no testing for Hepatitis B and Hepatitis C is required
Has a known history of active TB (Bacillus Tuberculosis)
History or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the study, interfere with the subject's participation for the full duration of the study, or is not in the best interest of the subject to participate, in the opinion of the treating investigator
Known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial
Expecting to conceive or father children within the projected duration of study participation, starting with the screening visit through 120 days after the last dose of trial treatment
