SPRINT: The Selective Personalized Radio-Immunotherapy for Locally Advanced NSCLC Trial.
Study Details
Study Description
Brief Summary
The goal of this study is to explore if, for locally advanced non-small cell lung cancer patients whose tumors have high levels of PD-L1 (a marker associated with benefits from immunotherapy), a combination of immunotherapy and a personalized 4-week radiotherapy course could be more effective than standard treatment, which is a combination of chemotherapy and radiotherapy.

| Phase 2 |
Detailed Description
This is a Phase II trial evaluating the efficacy and safety of sequential pembrolizumab (200 mg every three weeks) and accelerated, dose-painted radiotherapy for patients with locally advanced NSCLC with PD-L1 expression ≥ 50%. Patients with PD-L1 expression < 50% will also be enrolled and treated with standard concurrent chemoradiotherapy to serve as a non-randomized comparison group.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: PembroRT Cohort Subjects with PD-L1 expression ≥ 50% Combination of pembrolizumab and dose-painted radiotherapy for locally advanced NSCLC patients with high (≥ 50%) PD-L1 expression. |
Drug: PembroRT
Patients whose tumors are found to have high (≥ 50%) PD-L1 expression will automatically be placed in the PembroRT group. These patients will receive three intravenous treatments with pembrolizumab, followed by four weeks of daily radiotherapy, followed by up to 12 more treatments with pembrolizumab. Pembrolizumab is given as an intravenous infusion once every three weeks. This treatment course will last, in total, up to one year.
|
| Active Comparator: ChemoRT Cohort Subjects with PD-L1 expression < 50% Subjects with PD-L1 expression below 50% will be enrolled and treated with standard concurrent chemoradiotherapy. |
Drug: ChemoRT
Patients whose tumors are found to have low (< 50%) PD-L1 expression will automatically be placed in the ChemoRT group. These patients will receive radiotherapy over a course of four to seven weeks. During radiotherapy, patients will also receive two standard chemotherapy agents (carboplatin and paclitaxel) once each week. Following completion of chemotherapy and radiotherapy, patients may receive additional treatments with chemotherapy or immunotherapy as part of routine care. These treatments are optional and are not required by this clinical trial.

Eligibility Criteria
Criteria
Inclusion Criteria:
Participants are eligible to be included in the study only if all the following criteria apply:
-
Male/female participants who are at least 18 years of age on the day of signing informed consent with histologically confirmed diagnosis of non-small cell lung cancer will be enrolled in this study.
-
Previously untreated, pathologically proven NSCLC with measurable disease (at least 1 unidimensional, radiographically measurable lesion based on RECIST v1.1) and one of the following stages: (prior resection for early stage disease is allowed)
-
AJCC version 8 Stage II disease, medically or technically unresectable
-
AJCC version 8 Stage III disease
-
Whole body PET/CT within 42 days prior to study entry demonstrating hypermetabolic pulmonary lesion(s) and/or thoracic lymph node(s). If PET/CT was obtained more than 42 days prior to study entry and is not repeated, CT within 28 days prior to study entry demonstrating no evidence of metastatic disease is required.
-
MRI of the brain or head CT with contrast within 42 days prior to study entry.
-
PFTs within 42 days of study entry
-
ECOG performance status 0-1
-
Adequate end-organ function, based on routine clinical and laboratory workup:
-
ANC >1,500 cells/µl, Platelets ≥ 100,000 cells/µl, Hemoglobin ≥ 9.0 g/dl
-
Serum creatinine ≤ 1.5 x ULN or calculated creatinine clearance ≥ 50 ml/min
-
Total bilirubin ≤ 1.5 x ULN (or direct bilirubin below the ULN), AST and ALT ≤ 2.5 x ULN
-
International normalized ratio (INR) (or prothrombin time (PT)) and activated partial thromboplastin time (aPTT) ≤ 1.5 x ULN unless participant is receiving anticoagulant therapy, as long as values are within the intended therapeutic range
-
Thyroid stimulating hormone (TSH) within normal limits. If TSH is not within normal limits, the participant may be eligible if T3 and free T4 are within normal limits.
-
A female participant is eligible to participate if she is not pregnant (see Exclusion
Criteria), not breastfeeding, and at least one of the following conditions applies:
-
Not a woman of childbearing potential (WOCBP) as defined in the Appendix
-
A WOCBP who agrees to follow the contraceptive guidance in the Appendix during the treatment period and for at least 120 days after the last dose of study treatment with pembrolizumab (pembroRT cohort) or at least 180 days after the last dose of chemotherapy (chemoRT cohort).
-
A male participant must agree to use contraception during the treatment period and for at least 28 days after the last dose of study treatment and refrain from donating sperm during this period.
-
The participant (or legally acceptable representative if applicable) provides written informed consent for the trial.
Exclusion Criteria:
Participants are excluded from the study if any of the following criteria apply:
-

-
Prior therapy with an anti-PD-1, anti-PD-L1, or anti-PD-L2 agent or with an agent directed to another stimulatory or co-inhibitory T-cell receptor (e.g., CTLA-4, OX-40, CD137).

-
Has known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial.
-

If urine pregnancy test is positive or cannot be confirmed as negative, a serum pregnancy test is required. If more than 72 hours elapse between screening pregnancy test and the first dose of study treatment, another pregnancy test (urine or serum) must be performed and must be negative.
