Study & Design

• Study Type: INTERVENTIONAL
• Study Design: SINGLE_GROUP

Arm && Interventions

Group	Intervention	Description
pembrolizumab + vorinostat	pembrolizumab; vorinostat	Pembrolizumab: 200 mg every 3 weeks, up to 35 administrations Vorinostat: 400 mg once daily, until progression

Primary Outcome Measures

Name	Time	Method
Objective Response Rate (ORR), investigator assessment	From inclusion to first and subsequent tumor assesment or progression, up to 24 months	Investigators will assess the ORR. The ORR is defined in each cohort as the percentage of evaluable patients for ORR, designate as the proportion of patients with best response of complete response (CR) or a partial response (PR) during treatment according to response evaluation criteria in solid tumors version 1.1 (RECIST v1.1).

Secondary Outcome Measures

Name	Time	Method
Duration Of Response (DOR)	From the first assessment of a CR or PR until the date of the first occurrence of PD or death from any cause	DOR will be evaluated in patients with either CR or PR. DOR is defined as the time from the first assessment of a CR or PR until the date of the first occurrence of progressive disease (PD) or death from any cause (if death occurred within predefined period), whichever occurs first.
Progression Free Survival (PFS)	From inclusion to disease progression or death, up to 36 months	PFS is defined per RECIST v1.1 as the time from inclusion until disease progression (per RECIST v1.1) or death from any cause, whichever occurs first. At the time of analysis, a patient alive and without disease progression will be censored at the date of the last tumor assessment. Patients alive without disease progression who started a new anticancer therapy will be censored at the date of the last tumor assessment prior to the start of the new anticancer therapy.
Objective Response Rate (ORR), central assessment	From inclusion to first and subsequent tumor assesment or progression, up to 36 months	ORR defined as the proportion of patients with best response of CR or PR during treatment, as assessed by a central radiological panel according to RECIST v1.1.
Overall Survival (OS)	From inclusion to death from any cause, up to 36 months	OS is defined as the time from inclusion until death from any cause. Patients who are alive at last follow-up news will be censored at this date.
immune Objective Response Rate (iORR), central assessment	From inclusion to first and subsequent tumor assesment or progression, up to 36 months	ORR defined as the proportion of patients with best response of CR or PR during treatment, as assessed by a central radiological panel according to immune-specific response criteria.
immune Progression Free Survival (iPFS)	From inclusion to disease progression or death, up to 36 months	iPFS is defined per immune-specific response evaluation criteria in solid tumors (iRECIST) as the time from inclusion until confirmed disease progression (per iRECIST), or death from any cause, whichever occurs first. At the time of analysis, a patient alive and without progression will be censored at the date of the last tumor assessment. Patients alive without disease progression who started a new anti-cancer therapy will be censored at the date of the last tumor assessment prior to the start of the new anticancer therapy.
