---|---|
Experimental: S64315 and venetoclax administered in combination |
Combination Product: S 64315 (also referred as MIK665) and venetoclax
The treatment combination period can only begin after the planned dose of venetoclax is reached. Depending on the administration dosing schedule, the combination treatment at the planned doses may be preceded by a 2-week Lead-In Dose period of S64315 (fixed dose) during which the patient continues to receive venetoclax daily. Once the planned dose of both drugs is reached the schedule will be a 21-day cycle with a weekly regimen for S64315 and a daily regimen for venetoclax. S64315 should be administered 2 to 4 hours after venetoclax intake, via IV infusion. The dose escalation will start at 50 mg once a week and doses up to 250 mg once a week might be explored. Venetoclax will be administered orally once a day. The dose escalation will start at 100 mg daily and doses up to 600 mg daily might be explored. Venetoclax must be taken with a meal (ideally during breakfast) in order to avoid reduced efficacy. |

- Eastern Cooperative Oncology Group (ECOG) performance status ≤ 2
- Able to comply with study procedures
-
Adequate renal function within 7 days before the inclusion of the patient defined as:
• Serum creatinine ≤ 1.5 x ULN (upper normal limit) or calculated creatinine clearance (determined by MDRD) > 50 mL/min/1.73m2
-
Adequate hepatic function within 7 days before the inclusion of the patient defined as:

- Uncontrolled hepatitis B or C infection
- Known active acute or chronic pancreatitis
- History of myocardial infarction (MI), unstable angina pectoris, coronary artery bypass graft (CABG) within 6 months prior to starting study treatment
- Any factors that could increase the risk of QTc prolongation or risk of arrhythmic events.
