This testing can be from archival or fresh tissue sample and/or blood specimen; any sample, any test positive subjects are eligible.

  5. Treatment experience

    a. Cohort 1: Anti-tumor treatment naïve subject upon refusal to receive 1st line standard of care, or not tolerated to 1st line standard of care, or progressed after standard of care with no greater than 2 prior treatment regimens (neoadjuvant, adjuvant, and maintenance therapies do not qualify as separate treatment regimens).

  6. At least one measurable lesion per response evaluation criteria in solid tumors (RECIST) 1.1, with the exception of bone-only disease (i.e., non-measurable disease per RECIST 1.1) with at least 1 radiological non-target lesion.

    4. Use of an intrauterine contraceptive device. Note: Abstinence, the rhythm method, and/or contraception by the partner are not acceptable methods of birth control
  8. Resolution of prior-therapy-related AEs (including immune-related AEs but excluding alopecia) to ≤ Grade 1 per CTCAE v 5.0, and no treatment for these AEs for at least 2 weeks prior to the time of enrollment.
