This is an open-label, non-randomized phase II trial of durvalumab in combination with
platinum-based doublet chemotherapy. Patients with stage IV NSCLC with HIV (cohort 1) or
HBV/HCV (cohort 2) infection will be eligible. Patients will receive standard chemotherapy
plus durvalumab (1500 mg Q3W) every three weeks for 4 cycles, followed by maintenance
treatment with durvalumab (1500 mg Q4W; with or without pemetrexed for non-squamous NSCLC per
the discretion of the investigator).
Patient will be enrolled into the trial using an optimal two-stage phase II trial design. If
0 of the 7 achieved a response, no further patients will be enrolled in that cohort. If 1 or
more of the first 7 patients has a response, accrual would continue until a total of 18
patients have been enrolled in that cohort. Objective response will be evaluated using the
Response Evaluation Criteria in Solid Tumors (RECIST) 1.1. Safety and tolerability will be
evaluated by assessing the incidence of treatment-related grade 3 or higher AEs.
Treatment-related grade 3 or higher AEs will be defined as any grade 3 or higher AEs that
occur during the first 42 days of treatment and are related to the study treatment. AEs will
be evaluated using the Common Terminology Criteria for Adverse Events (CTCAE) version 5.0.
Subjects will receive 4 cycles of combination treatment: durvalumab (1500 mg every 3 weeks)
in combination with platinum-based doublet chemotherapy. The platinum-based doublet
chemotherapies (carboplatin plus paclitaxel/nab-paclitaxel vs. pemetrexed plus
carboplatin/cisplatin) are dependent on the tumor histology of the subject (squamous vs.
non-squamous). Only subjects who achieve stable disease or better radiological response after
4 cycles of induction treatment will be eligible to continue study treatment in maintenance.
The choice to treat non-squamous subjects with pemetrexed maintenance after the 4 induction
cycles will be determined by the investigator.

- 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:
Males: Creatinine CL (mL/min) = [Weight (kg) x (140 - Age)] / [72 x serum creatinine
(mg/dL)] Females: Creatinine CL (mL/min) = [Weight (kg) x (140 - Age) x 0.85] / [72 x
serum creatinine (mg/dL)]
7. 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 amenorrheic for 12 months without an alternative medical cause. The following
age-specific requirements apply:
- Women <50 years of age would be considered post-menopausal if they have been
amenorrheic 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).
- Women ≥50 years of age would be considered post-menopausal if they have been
amenorrheic 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
