she will have to

live in this country, and pay her doctor visits, lab tests, all radiology scans and travel expenses if any. The study medications/injections will be free. You can still try applying for financial assistance at the hospital.
She will be randomized into one of the many arms, are you sure she is ready to receive cisplatin/carboplatin if she ends up in arms A/B/C? You may want to check another study that I just post here, under stonypoint's video link, in which everyone gets nivolumab injection only and available at many more location nation wide.
