Pembrolizumab and Radiation Therapy in Patients With Relapsed or Refractory Multiple Myeloma

August 13, 2024 updated by: Mohammad K. Khan, Emory University

Pilot Study of Pembrolizumab and Single-Fraction, Low-Dose, Radiation Therapy in Patients With Relapsed or Refractory Multiple Myeloma

This pilot clinical trial studies the side effects of pembrolizumab and radiation therapy in treating patients with stage I-III multiple myeloma that has come back after a period of improvement or that does not respond to treatment. Monoclonal antibodies, such as pembrolizumab, may block cancer growth in different ways by targeting certain cells. Radiation therapy uses high energy x-rays to kill cancer cells and shrink tumors. Giving pembrolizumab and radiation therapy may work better in treating patients with stage I-III multiple myeloma.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

PRIMARY OBJECTIVE:

I. To evaluate the safety of concurrent single/low dose radiation therapy (radiotherapy) (8 Gy/1fx) in combination with pembrolizumab in relapsed or refractory myeloma patients.

SECONDARY OBJECTIVES:

I. To characterize late toxicity (Common Terminology Criteria for Adverse Events [CTCAE] > grade 2 toxicity at 6 and 12 months) and the effect of radiation in combination with pembrolizumab on systemic response rates using international myeloma working group (IMWG) uniform response criteria for multiple myeloma at 6 months and 12 months.

II. To assess changes in positron emission tomography/computed tomography (PET/CT) as a result of combining pembrolizumab and radiotherapy at 6 months and 12 months.

OUTLINE:

Patients undergo radiation therapy on day 1. Patients also receive pembrolizumab intravenously (IV) over 30 minutes on day 2 or 3. Courses with pembrolizumab repeat every 3 weeks for 2 years in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 30 days and then every 12 weeks thereafter.
