Phase 1/Phase 2 |
Detailed Description
A phase I/II study of the efficacy of CPX-351 treatment in patients with higher risk myelodysplastic syndromes : as first line treatment or after hypomethylating agents failure.
CPX-351 is an advanced liposomal formulation of daunorubicin and cytarabine encapsulated at a 1:5 ratio.
Patients will receive induction treatment with CPX-351. Patients in response (complete response (CR), complete response with incomplete hematologic improvement (CRi), partial response (PR)) after induction will receive monthly courses of consolidation therapy with CPX-351.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Cohort A - First line treatment Untreated patients |
Drug: CPX-351 in cohort A
Treatment by CPX-351 via intravenous infusion over 90 minutes.
Induction treatment with CPX-351 100 Units/m²/D on days 1, 3 and 5.
If response after this induction treatment, 4 courses of consolidation therapy with CPX-351 100 Units/m²/D on day 1.
If no response after this induction treatment, a second induction course of CPX-351 100 Units/m²/D on days 1 and 3. If response is achieved after this salvage course, 3 courses of consolidation therapy with CPX-351 100 Units/m²/D on day1.
|
| Experimental: Cohort B - Hypomethylating failure Patients in absence of response after hypomethylating agents treatment |
Drug: CPX-351 in cohort B
Treatment by CPX-351 via intravenous infusion over 90 minutes.
This will be a dose-finding study : CPX-351 100 Units/m²/D on days 1, 3 and 5 or CPX-351 100 Units/m²/D on days 1 and 3 or CPX-351 60 Units/m²/D on days 1 and 3.
In response after induction treatment, 4 monthly courses of consolidation therapy with CPX-351 at the same dose on day 1.

Eligibility Criteria
Criteria
Inclusion Criteria:
-
Myelodysplastic syndrome (WHO 2016 classified) including CMML (even if white blood cell count (WBC) > 13000/mm3).
-
For COHORT A: untreated patients except by erythropoiesis stimulating agents,
Lenalidomide or non-chemotherapy during a phase of lower risk MDS; For COHORT B:
absence of response (CR, CRi, PR or HI according to international working group (IWG) 2006 for MDS) after a minimum of 6 cycles of single hypomethylating agent or relapse after a response.
-
For COHORT A: less than 20% of marrow blasts. For COHORT B: less than doubling of marrow blasts compared with onset of hypomethylating agent.
-
Classical international prognostic scoring system (IPSS) int-2 or high risk score.
-

-
For COHORT A: Performance status (ECOG grading) ≤ 1; For COHORT B: Performance status ≤ 2.
-
Eligible for standard intensive chemotherapy.
-
Absence of concomitant severe cardiovascular disease which would make intensive chemotherapy impossible, i.e. arrhythmias requiring chronic treatment, congestive heart failure or symptomatic ischemic heart disease, reduced left ventricular function assessed by multigated acquisition (MUGA) scan or echocardiogram.
-
Patient must have adequate organ function as indicated by the following laboratory values: Renal: Serum creatinine < 2 mg/dl or calculated creatinine clearance ≥ 60 mL/min by MDRD (modification of the diet in renal disease) or CKD-EPI (chronic kidney disease epidemiology collaboration) equation for patients with creatinine levels > 1.5xULN ; Hepatic: Serum total bilirubin ≤ 2.5xULN OR direct bilirubin ≤ ULN for patients with total bilirubin levels ≥ 2 mg/dL, aspartate aminotransferase (ALT) and alanine aminotransferase (ALT) ≤ 2.5xULN, Alkaline Phosphatase ≤ 5xULN (if > 2.5xULN, then liver fraction should be ≤ 2.5xULN).
-
Patients not known to be refractory to platelet transfusions.
-
Female subjects of child-bearing potential must agree to undergo medically supervised pregnancy test prior to starting study drug. The first pregnancy test will be performed at screening (within 7 days prior to first study drug administration), and on the day of the first study drug administration and confirmed negative prior to dosing and Day 1 before dosing all subsequent cycles. Female patient is not actively breastfeeding at the time of study entry.
-
Female patients are either post-menopausal, free from menses for > 2 years, surgically sterilized or willing to use 2 adequate barrier methods of contraception to prevent pregnancy or agree to abstain from becoming pregnant throughout the study, starting with Visit 1. Females of reproductive potential as well as fertile men and their partners who are female of reproductive potential must agree to abstain from sexual intercourse or to use two highly effective forms of contraception from the time of giving informed consent, during the study and for 6 months (females and males) following the last dose of CPX-351.
-
Male patients agree to use an adequate method of contraception for the duration of the study. Men should be advised not to father a child while receiving CPX-351 and for 6 months post study.
-
