Lung cancer patients get second chance with triple therapy combo

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Have proven diagnosis of recurrent advanced NSCLC, irrespective of histological subtype. 2. Be willing and able to provide written informed consent/assent for the trial. 3. Must still have measurable disease based on RECIST 1.1 after application of study SBRT. Lesions that were irradiated prior to the study, but have progressed since irradiation but prior to study inclusion will be allowed as measurable disease. 4. Must provide newly obtained tissue from a core or excisional biopsy of a tumor lesion and are willing to have a second biopsy performed from any non-irradiated lesion after the radiation and immune-modulating treatment. This lesion may be used for RECIST measurements. 5. Have a performance status of 0 or 1 on the ECOG Performance Scale. 6. Stage IV NSCLC treated with at least PD-(L)1 blockade. There is no maximum number of previous lines of systemic treatment. Patients with both primary or acquired resistance to PD-(L)1 inhibition may be considered eligible. However, in the 1st stage ≥4 of 12 patients, in the 2nd stage a total of ≥8 of 25 patients and in the 3rd stage a total of ≥27 of 54 patients need to fulfill the definition of acquired resistance. Also, a maximum of 27 patients with a PD-L1 negative tumor will be included. 7. Have at least 2 separate (metastatic) lesions of which one is eligible for irradiation and another for biopsy and RECIST tumor evaluation. 8. Demonstrate adequate organ function. All screening labs should be performed within 14 days of treatment initiation. 9. Female subject of childbearing potential should have a negative serum pregnancy test within 72 hours prior to receiving the 1st dose of study medication. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required. 10. Female subjects of childbearing potential should be willing to use 2 methods of birth control or be surgically sterile, or abstain from heterosexual activity for the course of the study through 6 months after the last dose of study medication. Subjects of childbearing potential are those who have not been surgically sterilized or have not been free from menses for \> 1 year. 11. Male subjects should agree to use an adequate method of contraception starting with the 1st dose of study therapy through 6 months after the last dose of study therapy Exclusion Criteria: The subject must be excluded from participating in the trial if the subject: 1. Has a non-smoking-related targetable driver mutation, e.g. EGFR, ALK, RET or ROS1. Patients with advanced NSCLC with a smoking-related targetable driver mutation, e.g. KRAS or BRAF, may be found eligible if they have a history of ≥10 PY, but only when all options for targeted therapy have been exhausted and when progression on previous PD-(L)1 blockade has occurred. 2. Is currently participating in or has participated in a study of an investigational agent or using an investigational device within 4 weeks of the 1st dose of treatment. 3. Has not recovered (i.e. ≤ Grade 1 or at baseline) from adverse events due to a previously administered agent. * Note: Subjects with ≤ Grade 2 neuropathy are an exception to this criterion and may qualify for the study. * Note: Patients who experienced significant autoimmune side effects related to previous PD-(L)1 checkpoint inhibition, i.e. requiring use of steroids or other anti-inflammatory drugs and/or the need to (temporarily) withhold PD-(L)1 checkpoint inhibition, may be considered eligible after discussion with the coordinating investigator if adverse events have recovered, i.e. ≤ Grade 1 or at baseline. * Note: If subjects received major surgery (defined as surgical intervention requiring general or spinal anesthesia and hospital admission), they must have recovered adequately from the toxicity and/or complications from the intervention prior to starting therapy. Major surgery within 14 days prior to start of study treatment is not allowed. 4. Has had previous radical radiation to any tumor site within 3 months prior to study Day 1. Previous palliative radiation to any tumor site is not considered an exclusion criterion; however, this site will not be eligible for SBRT, biopsy location or RECIST tumor evaluation within this study. 5. Has received prior therapy with any antibody or drug specifically targeting T-cell co-stimulation or checkpoint pathways other than PD-(L)1 blockade, e.g. anti-CD137 or a CTLA-4 antibody. 6. Patients who have uncontrolled central nervous system (CNS) metastases. Patients who have untreated asymptomatic CNS metastases no greater than 2cm before start of treatment may be eligible. Patients who have any CNS lesion that is symptomatic, greater than 2cm, show significant surrounding edema on MRI scan or have leptomeningeal disease will not be eligible. Patients who have previously been treated for CNS metastases are eligible when they comply with the hereby mentioned criteria. NB. A brain lesion is not amendable for study SBRT. 7. Has a known additional malignancy that is progressing or requires active treatment. 8. Has an active autoimmune disease or a documented history of clinically severe autoimmune disease or syndrome that requires systemic steroids or immunosuppressive agents. Subjects who require intermittent use of bronchodilators or local steroid injections would not be excluded from the study. Patients with an active or history of autoimmune disease or syndrome who underwent previous PD-(L)1 checkpoint inhibition without significant side effects, i.e. not requiring use of steroids or other anti-inflammatory drugs and/or the need to (temporarily) withhold PD-(L)1 checkpoint inhibition, may be considered eligible for this trial after discussion with the coordinating investigator. Requirement for immunosuppressive doses of systemic corticosteroids ≤10 mg/day prednisone or equivalent may be considered eligible after discussion as well. 9. Has evidence of symptomatic interstitial lung disease or an active, non-infectious pneumonitis. 10. Has an active infection requiring systemic therapy.
