Has been treated with one or more lines of non-CPI targeted therapy that is locally approved for the subject’s applicable genomic alteration at the time of screening; OR one or more of the agents specified in the table below; i. Those who received a targeted agent as adjuvant therapy for early stage disease must have relapsed or progressed while on the treatment or within 6 months of the last dose OR received at least one additional course of targeted therapy for the same genomic alterations (which may or may not be same agent used in the adjuvant setting) for relapsed/progressive disease. ii. Subjects who have been treated with a prior TKI must receive additional targeted therapy, if clinically appropriate, for the applicable genomic alterations, or the subject will not be allowed in the study.
• Must undergo a mandatory pre-treatment tumor biopsy procedure. OR If available, a tumor biopsy that was recently collected (within 3 months of screening) after completion of the most recent anticancer treatment regimen and that has a minimum of 10 × 4 micron sections or a tissue block equivalent of 10 × 4 micron sections may be substituted for the mandatory biopsy collected during screening. Note: Results from this biopsy will not be used to determine eligibility for the study.

• If the subject is a female of childbearing potential, she must have a negative serum pregnancy test at screening and must be willing to use highly effective birth control upon enrollment, during the Treatment Period, and for 7 months following the last dose of study drug. Females of non-childbearing potential are defined as pre-menopausal females with a documented tubal ligation or hysterectomy, or postmenopausal (defined as 12 months of spontaneous amenorrhea [in questionable cases, a blood sample with simultaneous follicle stimulating hormone (FSH) > 40 mIU/mL and estradiol < 40 pg/mL/147 pmol/L is confirmatory]). Females on hormone replacement therapy (HRT) and whose menopausal status is in doubt will be required to use 1 of the contraception methods outlined for women of child-bearing potential if they wish to continue their HRT during the study. Otherwise, they must discontinue HRT to allow confirmation of post-menopausal status prior to study enrollment. For most forms of HRT, at least 2 to 4 weeks will elapse between the cessation of therapy and the blood draw; this interval depends on the type and dosage of HRT. Following confirmation of their post-menopausal status, they can resume use of HRT during the study without use of a contraceptive method.
• If male, the subject must be surgically sterile or must use a condom in addition to highly effective birth control if their partners are of reproductive potential upon enrollment, during the Treatment Period, and for 4 months after the final dose of study drug administration.
• Male subjects must not freeze or donate sperm starting at Screening and throughout the study period, and at least 4 months after the final study drug administration. Preservation of sperm should be considered before enrollment in the study.
• Female subjects must not donate, or retrieve for their own use, ova from the time of screening and throughout the study treatment period, and for at least 7 months after the final study drug administration. Preservation of ova should be considered prior to enrollment in the study.
• Be willing and able to comply with scheduled visits, drug administration plan, laboratory tests, other study procedures, and study restrictions.
• Has a life expectancy ≥ 3 months based on investigator’s opinion.

Exclusion Criteria:

• Has spinal cord compression or clinically active central nervous system metastases, defined as untreated and symptomatic, or requiring therapy with corticosteroids or anticonvulsants to control associated symptoms. Subjects with clinically inactive brain metastases may be included in the study. Subjects with treated brain metastases that are no longer symptomatic and who require no treatment with corticosteroids or anticonvulsants may be included in the study if they have recovered from the acute toxic effect of radiotherapy. A minimum of 2 weeks must have elapsed between the end of whole brain radiotherapy and study enrollment. Note: A CT or magnetic resonance imaging (MRI) scan of the brain at baseline is required for all subjects. For those subjects in whom central nervous system (CNS) metastases are first discovered at the time of screening, the treating investigator should consider delay of study treatment to document stability of CNS metastases with repeat imaging at least 4 weeks later (in which case, repeat of all screening activity may be required).
