Resolution of all toxicities of prior therapy or surgical procedures.
Any prior radiation must have been completed at least 7 days prior to the start of study drugs, and patients must have recovered from any acute adverse effects prior to the start of study treatment.

Exclusion Criteria:

Chemotherapy or small molecule antineoplastic agent given within 21 days or <5 half-lives, whichever is shorter, prior to first dose of study drug.
History or current condition, therapy, or laboratory abnormality that might confound the study results or interfere with the patient's participation for the full duration of the study treatment.
Patients who are pregnant or breastfeeding.
Life-threatening illness, medical condition, active uncontrolled infection, or organ system dysfunction or other reasons which, in the investigator's opinion, could compromise the participating patient's safety.
Major surgery within 4 weeks prior to first dose of RP-6306.
Uncontrolled, symptomatic brain metastases.
Uncontrolled hypertension.
Certain prior anti-cancer therapy
Psychological, familial, sociological, or geographical conditions that do not permit compliance with the protocol and/or follow-up procedures outlined in the protocol.
