CRITERIOS DE INCLUSIÓN
Written informed consent provided prior to any study-related procedure.
Must have recovered from the toxic effects of previous treatments to at least Grade 1, except for neurotoxicity (which should return at least to Grade 2 or baseline) and alopecia.
Clinical laboratory parameters as follows: - Peripheral WBC count, no upper limit at Screening, but must be <25 x10^9/L on Day 1 prior to first dose of study drug (see acceptable methods of cytoreduction above) - Platelet (PLT) count >10^9/L at the time of first study drug administration (PLT count < 10^9/L, participant must receive a transfusion within a maximum 24 hours before study drug administration) - Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) 3X the upper limit of normal (ULN) - Creatinine clearance 40 mL/min (Cockcroft and Gault formula; Section 10.7). - Total bilirubin 1.5X ULN Note: Participants with Gilberts syndrome may be enrolled provided that direct bilirubin is within the acceptable range as specified in this protocol, and there is no evidence of clinically significant hepatic dysfunction.
Adequate cardiac function confirmed by left ventricular ejection fraction 40% as per echocardiography.
For women of childbearing potential (WOCBP), a negative pregnancy test must be confirmed during Screening and within 3 days prior to first dose of study drug. WOCBP must commit to using a highly effective method of contraception during study participation and until 28 weeks (approximately 6.5 months) after the last dose of RVU120 (Section 10.4) OR For males, an effective barrier method of contraception must be used during study participation and until 28 weeks (approximately 6.5 months) after the last dose of RVU120, if the participant is sexually active with a WOCBP (Section 10.4).
Agree not to donate blood, eggs (ova) or sperm, during study participation and until 28 weeks (approximately 6.5 months) after the last dose of RVU120 (Section 10.4).
Investigator considers the participant to be suitable for participation in the clinical study by assessing that they: - understand the requirements of the clinical study and can give informed consent - can comply with study medication dosing requirements and all study-related procedures and evaluations - are not considered to be potentially unreliable and/or not cooperative.
Has received vaccinations in accordance with institutional standards and local regulatory requirements, if applicable.
