metastatic disease.

- Patients who are receiving up to two cycles of cisplatin plus gemcitabine as the
first line systemic therapy while waiting for results of molecule profiling
including IDH1/IDH2 mutational status, are eligible, provided that a radiographic
assessment during screening demonstrates the absence of interval disease
progression since initiation of chemotherapy treatment, and all other eligibility
criteria are met.

21. Measurable disease as determined by RECIST 1.1.

as long as a minimum of 4 weeks has elapsed between achieving sustained viral response
(SVR12 or SVR24) and starting study drug.

12. Known human immunodeficiency virus (HIV); excluded due to potential drug-drug
interactions between anti-retroviral medications and LY3410738.

dose of durvalumab, with the exception of intranasal and inhaled corticosteroids or
systemic corticosteroids which should not exceed 10 mg/day of prednisone or equivalent
corticosteroid.
