This phase II trial finds out the effect of local consolidative therapy and durvalumab in treating patients with stage III non-small cell lung cancer that has 3 or fewer lesions of progression (oligoprogressive) and greater than 3 lesions of progression (polyprogressive) after chemoradiation and anti-PD-l1 therapy. Local consolidative therapy, such as surgery and/or radiation, after initial treatment may kill any remaining tumor cells. Immunotherapy with durvalumab, may induce changes in body's immune system and may interfere with the ability of tumor cells to grow and spread. Giving local consolidative therapy and durvalumab may help to control the disease.
Eligibility criteria
Qualifiers
Capable of giving signed informed consent which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and in this protocol
Stage III NSCLC (AJCC 7th and 8th edition) patients who received standard chemoradiation followed by durvalumab therapy with either progressive disease or persistent disease. Persistent disease defined as residual positron emission tomography (PET) avidity 6 months after completion of initial definitive therapy and confirmed with biopsy
For lung adenocarcinoma patients, patients must not harbor any EGFR sensitizing mutations, ALK fusion, ROS1 rearrangements, RET fusions, or MET exon 14 skipping mutations where there are standard of care therapy options available. For patients with histologies other than adenocarcinoma, EGFR and ALK status is not required. Adenocarcinoma patients may be consented prior to the EGFR, ALK, and ROS1 status being known, but EGFR, ALK, and ROS1 status must be determined prior to initiating therapy. EGFR, ALK, and ROS ALK status may be determined using either tumor- or plasma-based, Clinical Laboratory Improvement Act (CLIA)-certified assays. For patients with NSCLC, not otherwise specified (NOS), EGFR testing is not required, as the frequency of alterations is exceedingly rare in this histology
Cohort A: Oligoprogressive disease is defined as having 3 or fewer lesions of progression (sites can be local, distant, or both). Multiple mediastinal lesions will be counted as 1 lesion
Disqualifiers
Patients who rapidly progressed on the PACIFIC regimen (chemoradiotherapy [CRT] + durvalumab). This is defined as any progression on the first 3-month imaging scan after starting durvalumab post-CRT
Patients who were treated with anti-PD-(L)1 therapy other than durvalumab
Participation in another clinical study with an investigational product during the last 4 weeks
Concurrent enrolment in another clinical study, unless it is an observational (non-interventional) clinical study. No other investigational therapy is permitted after durvalumab and start of this protocol
