3. see protocol
4. Known to be human immunodeficiency virus (HIV) positive. Note: The sponsor has evaluated whether to include subject with HIV. Given that this is the first combination study of E7386 with lenvatinib and that the main mechanism of action of E7386 is immunomodulation of the tumor microenvironment along with the fact that several anti-retroviral therapies have drug-drug interaction with cytochrome P450 3A (CYP3A) substrates, the sponsor has decided not to include these subjects at the current time. However, further considerations will be made moving forward based on new emerging data. Note: HIV testing is required at screening only when mandated by local health authority.
