Testing Pembrolizumab Versus Observation in Patients With Merkel Cell Carcinoma After Surgery, STAMP Trial

Phase 3

Active, not recruiting

Conditions: Pathologic Stage I Cutaneous Merkel Cell Carcinoma AJCC v8
Pathologic Stage II Cutaneous Merkel Cell Carcinoma AJCC v8
Pathologic Stage III Cutaneous Merkel Cell Carcinoma AJCC v8

Interventions: Procedure: Biospecimen Collection
Other: Best Practice
Procedure: Computed Tomography
Procedure: Magnetic Resonance Imaging
Biological: Pembrolizumab
Procedure: Positron Emission Tomography
Radiation: Radiation Therapy

Registration Number: NCT03712605

Lead Sponsor: National Cancer Institute (NCI)

Brief Summary: This phase III trial studies how well pembrolizumab works compared to standard of care observation in treating patients with stage I-III Merkel cell cancer that has been completely removed by surgery (resected). 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.

Detailed Description: PRIMARY OBJECTIVE:

I. To compare recurrence free survival (RFS) and overall survival (OS) as co-primary endpoints across the two arms.

SECONDARY OBJECTIVES:

I. To evaluate adverse events. II. To evaluate distant metastasis free survival (DMFS). III. To evaluate the impact of radiation on clinical outcomes (OS, RFS, DMFS).

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM A: Patients receive pembrolizumab intravenously (IV) over 30 minutes on day 1 of each cycle. Treatment repeats every 21 days for up to 17 cycles in the absence of disease progression or unacceptable toxicity. Patients may also undergo standard of care radiation therapy within 14 days of day 1, cycle 1. Patients undergo positron emission tomography (PET)-computed tomography (CT), CT, or magnetic resonance imaging (MRI) throughout the trial. Patients may also undergo blood and utine sample collection as clinically indicated at the discretion of the treating investigator.

ARM B: Patients receive standard of care observation every 3 months for 1 year, and then every 6 months for 5 years. Patients may also undergo standard of care radiation therapy within 14 days of day 1, cycle 1. Patients undergo PET-CT, CT, or MRI throughout the trial. Patients may also undergo blood and urine sample collection as clinically indicated at the discretion of the treating investigator.

After completion of study treatment, patients are followed up every 3-6 months for 5 years from the date of registration.

Target Recruitment: 280

Inclusion Criteria

Patient must be >= 18 years of age
Patients must have an Eastern Cooperative Oncology Group (ECOG) performance status: 0, 1, or 2 (However, those patients with a performance state of 3 because they are wheel chair bound due to congenital or traumatic events more than one year before the diagnosis of Merkel cell carcinoma are eligible).
Patient must not be pregnant or breast-feeding due to the unknown effects of the study drug in this setting. All patients of childbearing potential must have a blood test or urine study within 2 weeks prior to randomization to rule out pregnancy. A patient of childbearing potential is anyone, regardless of sexual orientation or whether they have undergone tubal ligation, who meets the following criteria: 1) has achieved menarche at some point, 2) has not undergone a hysterectomy or bilateral oophorectomy; or 3) has not been naturally postmenopausal (amenorrhea following cancer therapy does not rule out childbearing potential) for at least 24 consecutive months (i.e., has had menses at any time in the preceding 24 consecutive months).
Patients on Arm A pembrolizumab (MK-3475) must not conceive or father children by using accepted and effective method(s) of contraception or by abstaining from sexual intercourse from the time of registration, while on study treatment, and continue for 120 days after the last dose of study treatment. For patients on Arm B only receiving radiation therapy, contraception use should be per institutional standard.
Patient must have a histological confirmation of diagnosis of Merkel cell carcinoma (MCC), pathologic stages (American Joint Committee on Cancer [AJCC] version 8) I-IIIb.
- Stage I patients with negative sentinel lymph node biopsy are ineligible. Patients who have a positive biopsy or for whom no biopsy was done are eligible.
- Patients with distant metastatic disease (stage IV) are ineligible.
- The primary tumor must have grossly negative margins. (Microscopically positive margins are allowed).
- Cancers of unknown primary that have regional disease only are eligible.

All patients must have disease-free status documented by a complete physical examination and conventional imaging studies within 8 weeks prior to randomization.
Patient may not have a history of distant metastatic disease.
- NOTE: Loco-regional recurrent disease is acceptable, as long as this is not metastatic (prior surgery with or without radiation therapy is acceptable).
For patients with initial presentation of Merkel cell carcinoma, patient must have no previous systemic therapy or radiation therapy prior to surgery for Merkel cell carcinoma and cannot have completed adjuvant radiation therapy for Merkel cell carcinoma more than 6 weeks prior to randomization. Patients actively undergoing radiation therapy or having completed adjuvant radiation therapy within 6 weeks of randomization are eligible, as long as resection date is within 16 weeks of randomization. Patients with prior radiation at a non-Radiation Oncology Core (IROC) provider are eligible for the trial. If the patient has not received radiation, and treatment at a Radiation Oncology Core (IROC) provider is not possible, the patient can start and complete radiation prior to randomization, with recommendations to follow radiation protocol guidelines with submission of treatment records.

Primary Outcome Measures

Name	Time	Method
OS	From randomization until death, assessed up to 5 years	An ITT analysis using the stratified log-rank test will be performed to compare OS and RFS between the two arms.
Recurrence free survival (RFS)	From randomization until disease recurrence or death from any cause; assessed up to 5 years	An intention-to-treat (ITT) analysis using the stratified log-rank test will be performed to compare overall survival (OS) and RFS between the two arms.

Secondary Outcome Measures

Name	Time	Method
Impact of radiation therapy on distant metastasis free survival (DMFS)	From randomization to distant metastasis, assessed up to 5 years	DMFS will be evaluated by treatment arms. If there is no distant metastasis, cases will be censored at the time of last assessment.
Incidence of adverse events	Up to 5 years	Measured per Common Terminology Criteria for Adverse Events version 5.0. Adverse events from each arm will be summarized and compared using Fisher's exact test.
Impact of radiation therapy on OS	Up to 5 years	OS in each arm will be evaluated by radiation treatment status (radiation vs. no radiation therapy). The analysis will be a planned post-hoc analysis with primary goal of examining whether use of post-operative radiation therapy is associated with OS. Cox multivariate models for OS will be developed to evaluate the impact of radiation therapy while adjusting for pembrolizumab treatment and clinical/ pathological factors. The treatment fields and dose data will also be included in the Cox model as covariates. Secondary analyses for radiation therapy will examine factors associated with the the use of post-operative RT. Multivariate logistic regression models (radiation therapy vs. no radiation therapy) will be developed to evaluate the associations with demographic, clinical/pathologic, and treatment-related factors and pembrolizumab treatment.
Impact of radiation therapy on RFS	Up to 5 years	RFS in each arm will be evaluated by radiation treatment status (radiation versus \[vs.\] no radiation therapy). The analysis will be a planned post-hoc analysis with primary goal of examining whether use of post-operative radiation therapy is associated with RFS. Cox multivariate models for RFS will be developed to evaluate the impact of radiation therapy while adjusting for pembrolizumab treatment and clinical/ pathological factors. The treatment fields and dose data will also be included in the Cox model as covariates. Secondary analyses for radiation therapy (RT) will examine factors associated with use of post-operative RT. Multivariate logistic regression models (radiation therapy vs. no radiation therapy) will be developed to evaluate the associations with demographic, clinical/pathologic, and treatment-related factors and pembrolizumab treatment.
