Brief Summary

Primary objective: To assess the early signals for anti-tumor activity (i.e. objective response rate, progression-free survival) of pembrolizumab in combination with vorinostat in patients with advanced prostate, renal or urothelial cell carcinoma. Secondary objectives: (1) To evaluate the overall safety profile of pembrolizumab in combination with vorinostat; (2) To assess the safety and tolerability of pembrolizumab in combination with vorinostat in patients with advanced prostate, renal or urothelial cell carcinoma in order to select the recommended Phase 2 Dose (RP2D); (3) To characterize immune cell subsets, and miRs in tumor and/or blood.

Detailed Description


This is a Phase I/Ib, open-label, safety, and pharmacodynamics study of pembrolizumab in
combination with vorinostat in patients with advanced prostrate, renal or urothelial cell
carcinoma. This clinical study will be composed of a Dose Finding Phase and an Expansion
Phase. The Dose Finding Phase will estimate the Recommended Phase II Dose (RP2D) in patients
with advanced renal and urothelial cell carcinoma patients. The Dose Finding Phase will lead
to the identification of an Expansion Test Dose for pembrolizumab in combination with
vorinostat. The Expansion Test Dose will be the Recommended Phase II Dose (RP2D) (i.e. the
highest tested dose that is declared safe and tolerable by the Investigators and Sponsor).
Patients will be treated with oral vorinostat every day for 14 days, and with pembrolizumab
at the fixed dose of 200 mg IV. Each cycle is every 21 days. Two dose levels of vorinostat
will be tested in 2-patient cohorts according to the 3 + 3 standard design (100 mg and 200
mg). 200 mg dose represents 50% of the recommended vorinostat dose as single agent.

For the Dose Finding Phase (Combination Phase), the starting dose level of vorinostat will be
100 mg by mouth (PO) every day for 14 days, with 7 days break. The first dose level will have
a minimum of 3 patients treated (unless the first 2 patients experience dose-limiting
toxicities (DLTs) before the 3rd patient is enrolled).

Once the RP2D is identified, the Dose Expansion Phase will be opened. During the Dose
Expansion Phase, the study will have a run-in phase with sequential single-agents and then
the combination phase. The run-in phase may be waived at the investigator's discretion. The
reason for the run-in phase during dose expansion is to obtain data on the immunomodulatory
effects of vorinostat separately from pembrolizumab. Forty-five patients with prior
treatments will be enrolled in three expansion cohorts: 15 anti-PD1 naive renal and
urothelial patients 15 anti-PD1 resistant renal and urothelial patients (defined as patients
with transient clinical response or without clinical response to prior immune-checkpoint
inhibition), and 15 patients with androgen-sensitive or castration-resistant prostate cancer.
The prostate cohort has been added in an amendment during the Dose Expansion Phase, and
therefore, will not be part of the Dose Finding Phase.

Primary Outcomes:

Primary Outcome 1 - Measure: Find Recommended Phase 2 Dose (RP2D) of pembrolizumab in combination with vorinostat

Primary Outcome 1 - Time Frame: 18 months

Condition:

  • Renal Cell Carcinoma
  • Urinary Bladder Neoplasms

Eligibility

Criteria:
Subject Inclusion Criteria

In order to be eligible for participation in this trial, the subject must:

1. Have one of the following diagnoses/conditions:

1. Renal cell carcinoma - previously treated and progressive disease, locally
advanced or metastatic

2. Urothelial cell carcinoma - previously treated and progressive disease, locally
advanced or metastatic

3. Prostate cell carcinoma - progressive disease, locally advanced or metastatic
disease (enrolling only at IUSCC and its affiliates). Patients with
hormone-sensitive disease where ADT in combination with either docetaxel or
abiraterone is indicated will not be eligible (i.e. patients with high burden
disease).

2. Be willing and able to provide written informed consent for the trial.

3. Be 18 years of age or older on day of signing informed consent.

4. Have measurable disease based on RECIST 1.1. for patients with solid malignancies or
evaluable disease as assessed by bone scan and/or PET scan. Patients with advanced or
metastatic prostate cancer can have either androgen-sensitive or castration-resistant
disease.

5. Have a performance status of 0-2 on the ECOG Performance Scale.

6. Demonstrate adequate organ function. All screening labs should be performed within 10
days of treatment initiation.

7. Female subject of childbearing potential should have a negative urine or serum
pregnancy test 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.

8. Subjects of childbearing potential should be willing to use 2 methods of contraception
for the course of the study through 120 days after the last dose of study medication.
Acceptable methods of birth control include: abstinence, partner with previous
vasectomy, placement of an intrauterine device (IUD), condom with spermicidal
foam/gel/film/cream/suppository, diaphragm or cervical vault cap, or hormonal birth
control (pills or injections). NOTE: Females are considered of childbearing potential
unless they are surgically sterile (they have undergone a hysterectomy, bilateral
tubal ligation, or bilateral oophorectomy) or they are postmenopausal (a woman who is
≥45 years of age and has not had menses for greater than 1 year).

9. Male subjects without a previous vasectomy should agree to use an adequate method of
contraception (i.e. abstinence, condom with spermicidal foam/gel/film/cream) starting
with the first dose of study therapy through 120 days after the last dose of study
therapy.

10. Subjects with urothelial carcinoma must have received a prior platinum-based regimen
in the metastatic setting or have signed consent for this study within 12 months of
receiving a platinum-based regimen in the perioperative setting (neoadjuvant or
adjuvant).

11. Subjects with a history of diabetes mellitus must have HgbA1c level of <8.5% upon
study entry.

Subject Exclusion Criteria

The subject must be excluded from participating in the trial if the subject:

1. Is currently participating and receiving study therapy or has participated in a study
of an investigational agent and received study therapy or used an investigational
device within 4 weeks of the first dose of treatment.

2. Has a diagnosis of immunodeficiency or is receiving systemic steroid therapy or any
other form of immunosuppressive therapy within 7 days prior to the first dose of trial
treatment.
