Cisplatin+Pembrolizumab+RT in Vulvar Cancer
A Phase 2 Study of Combined Chemo-immunotherapy With Cisplatin-pembrolizumab and Radiation for Unresectable Vulvar Squamous Cell Carcinoma
This research is being done to see how well the combination of a standard of care drug, investigational drug, and radiation therapy work against unresectable vulvar squamous cell carcinoma.
This research study involves the following:
- Cisplatin (standard of care drug)
- Pembrolizumab (investigational drug)
- Radiation Therapy (standard of care intervention)

Detailed Description
This is a single-arm phase 2 clinical trial involving women with unresectable, incompletely resected, recurrent, or metastatic vulva squamous cell carcinoma. This study combines cisplatin, pembrolizumab, and radiation therapy to see if this combination further increases participants' immune system's efficiency in killing their tumor, and if the combination decreases the chances of participants' cancer coming back.
The research study procedures include screening for eligibility and study treatment including evaluations and follow up visits.
This research study involves the following:
- Cisplatin (standard of care drug)
- Pembrolizumab (investigational drug)
- Radiation Therapy (standard of care intervention)
Participants will receive study treatment for up to 36 weeks and will be followed for up to 3 years.
It is expected that about 24 people will take part in this research study.
Phase II clinical trials test the safety and effectiveness of an investigational drug to learn whether the drug works in treating a specific disease. "Investigational" means that the drug is being studied. The U.S. Food and Drug Administration (FDA) has approved cisplatin as a treatment option for vulva squamous cell carcinoma. The FDA has not approved pembrolizumab for vulva squamous cell carcinoma, but it has been approved for other uses. Cisplatin is a chemotherapy drug and will be given to participants per standard of care.
Radiation therapy will be given to you per standard of care. Pembrolizumab is a drug that may target participants immune systems to increase its efficiency in targeting and killing illnesses and diseases, such as unresectable vulvar squamous cell carcinoma.

Eligibility Criteria
Ages Eligible for Study
Accepts Healthy Volunteers
Description
Inclusion Criteria:
- Participants must have histologically or cytologically confirmed unresectable, incompletely resected, recurrent, or metastatic squamous cell carcinoma of the vulva.Patients with unresectable disease are defined as T2 or T3 primary tumors (N0-3, M0) not amenable to surgical resection by standard radical vulvectomy.
- Participants must have measurable disease based on RECIST 1.1. Lesions situated in a previously irradiated area are considered measurable if progression has been demonstrated in such lesions.
- Have provided archival tumor tissue sample or newly obtained core or excisional biopsy of a tumor lesion not previously irradiated. Formalin-fixed, paraffin embedded (FFPE) tissue blocks are preferred to slides.
- Prior therapy: Participants with no prior therapy are eligible and patients with recurrent disease must not have had more than two lines of cytotoxic therapy. Topical or hormonal therapy are not counted towards prior lines. Prior treatment with immunotherapy is allowed, provided treatment was not stopped for grade 2 or greater adverse events.
Time from prior therapy:
- Systemic anti-neoplastic therapy: 5 half-lives or 4 weeks, whichever is shorter.
- Hormonal therapy is not considered anti-neoplastic therapy.
- Radiotherapy: Any prior irradiation is acceptable provided the site being considered for study has not been previously irradiated.
- Age ≥18 years. Because insufficient dosing or adverse event data are currently available on the use of pembrolizumab in combination with cisplatin-sensitized radiation therapy participants <18 years of age, children are excluded. Vulva cancer is rare in the pediatric population
- ECOG performance status of 0 or 1.
Participants must have adequate organ and marrow function as defined below (Table 1):

- ALT (SGPT)=alanine aminotransferase (serum glutamic pyruvic transaminase); AST (SGOT)=aspartate aminotransferase (serum glutamic oxaloacetic transaminase); GFR=glomerular filtration rate; ULN=upper limit of normal.
- Criteria must be met without erythropoietin dependency and without packed red blood cell (pRBC) transfusion within last 2 weeks.
- Creatinine clearance (CrCl) should be calculated per institutional standard.
- Note: This table includes eligibility-defining laboratory value requirements for treatment; laboratory value requirements should be adapted according to local regulations and guidelines for the administration of specific chemotherapies.
Participant must be female, and is eligible to participate if she is not pregnant (see Appendix B), not breastfeeding, and at least one of the following conditions applies:
- Not a woman of childbearing potential (WOCBP) as defined in Appendix B OR
- A WOCBP must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, during study treatment, and for at least twelve weeks after the last dose of study treatment. Should a woman become pregnant or suspect she is pregnant while she is pregnant while she is participating in this study, she should inform her treating physician immediately.
- Ability to understand and the willingness to sign a written informed consent document.
Exclusion Criteria:
- Patients who in the opinion of the investigator cannot safely receive a minimum of 30 Gy in 10 fractions are not eligible for the trial.
- Participants who have received prior systemic anti-cancer therapy including investigational agents within 4 weeks prior to first dose of study treatment.

Overall response rate (ORR)
Time Frame: Up to 36 weeks
|
To determine the Overall response rate (ORR) in patients undergoing combination therapy with pembrolizumab and cisplatin-sensitized external beam radiation therapy by RECIST 1.1 criteria. This sample size calculation is based on an ORR of greater than or equal to 60%. For recurrent metastatic disease, there are is no standard of care.The ORR estimation is informed by data showing an ORR of 40% in patients with advanced or recurrent metastatic vulvar cancer treated with platinum-based combination therapy. Single agent chemotherapy has an ORR of about 12% (5). Patients with primary disease who are not candidates for upfront surgery have a reported response rates from 55% to 64%. |
