March 3, 2023 updated by: Rachelle Lanciano M.D., Crozer-Keystone Health System

A Prospective Trail of Immunotherapy and Stereotactic Body Radiotherapy (SBRT) for the Treatment of Metastatic Lung Cancer: SBRT Sensitization of the Programmed Death-1 (PD-1) Effect

The purpose of this study is to determine efficacy, safety of Stereotactic Body Radiotherapy (SBRT) in combination with immunotherapy in participants with metastatic non-small cell lung cancer (NSCLC) who are eligible for an immunotherapy agent.

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

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Blockade of the PD-1/PD-L1 T-cell checkpoint pathway is an effective and well tolerated approach to stimulating the immune response which is a critical option in the treatment of metastatic NSCLC. However, progression free survival (PFS) is increased by only 2-4 months and median overall survival (OS) by 3-9 months.

There is compelling evidence that PFS is increased up to 3 fold and OS by 2 fold in patients receiving a course of radiation therapy while on immunotherapy. Radiotherapy is known to induce immunogenic tumor cell death and upregulation of dendritic cells and antigen presentation leading to activation of cytotoxic T-Cells. Dramatic T-cell activation has been demonstrated where tumor regression occurs outside the radiation treatment field in a phenomenon termed the abscopal effect and is associated with high dose radiation delivered via SBRT.

As such, SBRT activation of T-cells could be complementary to immunotherapy and enhance T-cell mediated killing via PD-L1 blockade which could lead to lasting and durable tumor response with improved progression free survival and overall survival.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Treatment Arm
Radiation: Stereotactic Body Radiotherapy

All patients in this trial will be treated with fractionated Stereotactic body radiation therapy.

SBRT will be delivered to <=3 sites in 3-5 fractions followed by administration of the specified immunotherapy agent (Nivolumab or Pembrolizumab). This approach will take advantage of the transient increase in antigen availability, increased antigen presentation and upregulation of PD-1 by tumor cells following ablative radiation therapy.
