Description

Summary

This is a pilot, single center, open-label study to examine the ORR, safety, and toxicity of avelumab in combination with SAR in non-responding and progressing NSCLC patients previously treated with a PD-1 Inhibitor.

Official Title

A Pilot Study of Avelumab and Stereotactic Ablative Radiotherapy in Non-responding and Progressing NSCLC Patients Previously Treated With a PD-1 Inhibitor

Details

Lung cancer is the leading cause of cancer deaths worldwide. More than half of lung cancer patients present with metastatic disease at diagnosis, with a median survival of only 10-12 months. In recent years the development of more efficacious therapies for metastatic non-small cell lung cancer (NSCLC) based upon an improved understanding of the underlying tumor biology has resulted in an improvement in median overall survival by several months. However, survival remains poor for most patients and there remains an urgent unmet need for novel treatment strategies to improve survival for these patients.

Avelumab is a fully human anti-PD-L1 IgG1 monoclonal antibody. In phase I studies, avelumab was well-tolerated at a dose of 10 mg/kg IV Q2 weeks with the most frequently observed treatment related adverse events including fatigue, infusion-related reactions, nausea, chills, diarrhea, and pyrexia. However, many patients will not respond to checkpoint inhibition, and developing strategies to further improve the efficacy and extend the benefit of these treatments to non-responding and progressing patients is an area of substantial need. Among NSCLC patients, approximately 80% of patients will not respond to a checkpoint inhibitor as monotherapy.

Combinatorial strategies may increase response rates. Radiotherapy is an intriguing partner therapy, with preclinical and clinical studies confirming the immunomodulatory effects of radiotherapy. There is particularly interest in the use of radiotherapy in patients who have failed a checkpoint inhibitor as monotherapy as this approach will isolate the effects of radiation in enhancing response rates.

Stereotactic ablative radiotherapy (SAR) (also known as stereotactic body radiotherapy or SBRT) has emerged as a potentially curative treatment option for patients with early stage, medically inoperable non-small cell lung cancer and as a safe and effective local treatment for metastatic lesions.

The investigators hypothesize that local radiotherapy can augment the systemic effects of avelumab in NSCLC patients previously refractory to a checkpoint inhibitor previously used as standard-of-care treatment. This proposal seeks to gain insight into the clinical and biological efficacy of this combination.

Open to people ages 18 years and up

  1. Signed informed consent.
  2. Ability to comply with the protocol.
  3. Adults >18 years of age with histologically proven stage IV non-small cell lung cancer.
  4. At least two sites of measurable disease as defined by RECIST 1.1; one of which must be amenable to treatment with SAR and accessible for a mandatory pre-treatment biopsy and a post- treatment biopsy at physician discretion. If a pulmonary nodule is being considered for SAR it must range in size from 1-5 cm.
  5. Have provided written consent for protocol directed biopsies.
  6. Patients with treated supratentorial metastases are allowed if stable, the patient is off steroids or on a stable or decreasing dose of ≤10 mg daily prednisone (or equivalent) and no evidence of intracranial hemorrhage.
  7. Archival tumor sample available. A minimum of 10 unstained slides. No fine needle aspiration (FNAs) allowed or tumor tissue from bone.
  8. ECOG performance status score of 0 or 1 (Appendix 1).
  9. Life expectancy ≥ 3 months.
  10. . Adequate hematologic and end organ function, defined by the following laboratory results obtained within 14 days of the first study treatment:
  11. Absolute neutrophil count (ANC) ≥ 1.5 × 109/L, platelet count ≥ 100 × 109/L, and hemoglobin ≥ 9 g/dL (may have been transfused)
  12. Liver function tests meeting the following criteria: total bilirubin level ≤ 1.5× the upper limit of normal (ULN) range and AST and ALT levels ≤ 2.5 × ULN or AST and ALT levels ≤ 5 × ULN (for subjects with documented metastatic disease to the liver).
  13. INR and aPTT <1.5 × ULN (for patients on anticoagulation they must be receiving a stable dose for at least 1 week prior to randomization)
  14. Creatinine clearance >30 mL/min by Cockcroft-Gault formula (or local institutional standard method).

below.

  1. . No chemotherapy or radiotherapy within the past 28 days.
  2. . Any number of prior treatments is allowed. Must have failed at least one treatment regimen for metastatic disease and must have failed platinum-based chemotherapy(including as treatment for localized disease) or be deemed ineligible for platinum-based therapy by the treating medical oncologist.
  3. . Most recent prior regimen was a PD-1 inhibitor (nivolumab or pembrolizumab) with progression. Last dose must have been delivered within 90 days of enrollment.
  4. . Highly effective contraception for both male and female subjects if the risk of conception exists. (Note: The effects of the trial drug on the developing human fetus are unknown; thus, women of childbearing potential and men able to father a child must agree to use 2 highly effective contraception, defined as methods with a failure rate of less than 1% per year. Highly effective contraception is required at least 28 days prior, throughout and for at least 60 days after avelumab treatment.
  5. . Negative serum pregnancy test at screening for women of childbearing potential.
