About

This study proposes to evaluate the safety and efficacy of an anti-PD-L1 (durvalumab) agent as neoadjuvant therapy in patients diagnosed with localized NSCLC who are planned to undergo radical RT or CRT. The hypothesis to be tested for the primary objective is that the treatment of durvalumab followed by RT/CRT will be safe and well tolerated in subjects with NSCLC.

Full description

Targeting the PD1/PD-L1 pathway has demonstrated activity in patients with several advanced malignancies. Treatment with anti-PD1/PD-L1 blockade in advanced and, more recently, locally advanced NSCLC, is already standard of care. The positive outcomes of durvalumab following CRT emphasized the potential of immunotherapy integration in multimodality treatment strategies and in earlier phases of the disease, leading to the first immune checkpoint inhibitor approval in non-metastatic setting in NSCLC. Furthermore, growing evidence is pointing to the efficacy of neoadjuvant treatments in NSCLC. This study proposes to evaluate the safety and efficacy of an anti-PD-L1 (durvalumab) agent as neoadjuvant therapy in patients diagnosed with localized NSCLC who are planned to undergo radical RT or CRT.

The hypothesis to be tested for:

Primary objective: To evaluate the safety, as assessed by incidence of dose limiting toxicity (DLT), of durvalumab followed by RT/CRT in patients with early stage or locally advanced, unresectable NSCLC who are planned to undergo radical RT or CRT.
Secondary Objectives: To evaluate the safety, the efficacy and the feasibility of durvalumab followed by RT/CRT.
Exploratory Objectives: To assess the Quality of Life (QoL) using SF-36v2 and EQ-5D-5L and to assess blood and tumor tissue for potential biomarkers which predict and/or correlate with clinical outcomes.

1. Hemoglobin ≥ 9.0 g/dL.
2. White blood cell (WBC) counts > 2.5 x 109/L.
3. Absolut neutrophil count (ANC) ≥ 1.5 x 109/L (without granulocyte colony-stimulating factor support within 2 weeks prior to durvalumab treatment).

5. Platelet count ≥100 x 109/L.
6. AST, ALT, and alkaline phosphatase ≤ 2.5 x the institutional upper limit of normal (ULN).
7. Serum bilirubin ≤ 1.5 x ULN. Patients with known Gilbert disease who have serum bilirubin level ≤ 3 x ULN may be enrolled.
8. International Normalized Ratio (INR) and activated Partial Thromboplastin Time (aPTT) ≤ 1.5 x ULN -This applies only to patients who are not receiving therapeutic anticoagulation; patients receiving therapeutic anticoagulation should be on a stable dose.
9. Serum albumin ≥2.5 g/dL.
10. Calcemia ≤2.65 mmol/L or Ca ≤10 mg/dL.
11. Measured creatinine clearance (CL) >40 mL/min or Calculated creatinine CL>40 mL/min by the Cockcroft-Gault formula (Cockcroft and Gault 1976) or by 24-hour urine collection for determination of creatinine clearance.
Patient is willing and able to comply with the protocol for the duration of the study including undergoing treatment and scheduled visits and examinations including follow up.
Evidence of post-menopausal status or negative urinary or serum pregnancy test for female pre-menopausal patients. Women will be considered post-menopausal if they have been amenorrhoeic for 12 months without an alternative medical cause. The following age-specific requirements apply:
1. Women <50 years of age would be considered post-menopausal if they have been amenorrhoeic for 12 months or more following cessation of exogenous hormonal treatments and if they have luteinizing hormone and follicle-stimulating hormone levels in the post-menopausal range for the institution or underwent surgical sterilization (bilateral oophorectomy or hysterectomy).
2. Women ≥50 years of age would be considered post-menopausal if they have been amenorrhoeic for 12 months or more following cessation of all exogenous hormonal treatments, had radiation-induced menopause with last menses >1 year ago, had chemotherapy-induced menopause with last menses >1 year ago, or underwent surgical sterilization (bilateral oophorectomy, bilateral salpingectomy or hysterectomy).
Women of Childbearing Potential must be willing to use 1 highly effective method of contraception, or to abstain from sexual activity, from the time of screening throughout the total duration of the drug treatment and for 3 months after the last session of RT/CRT. Non-sterilized male partners of a female patient of childbearing potential must use male condom plus spermicide throughout this period.
Non-sterilized male patients who are not abstinent and intend to be sexually active with a female partner of childbearing potential must use a male condom plus spermicide from the time of screening throughout the total duration of the drug treatment and for 3 months after the last session of RT/CRT. Male patients should refrain from sperm donation throughout this period. Female partners (of childbearing potential) of male patients must also use a highly effective method of contraception throughout this period.

Exclusion Criteria

2. Patients with irreversible toxicity not reasonably expected to be exacerbated by treatment with durvalumab may be included only after consultation with the Study Physician.
