Summary

To compare the event-free survival at 2 years of CPX-351 vs. conventional care regimens before allogeneic blood cell transplantation as first line treatment in patients with higher risk MDS and oligoblastic AML.

Description

Allogeneic stem cell transplantation (alloHCT) is considered the only potentially curative treatment option for MDS patients and is therefore often considered the standard treatment for mainly higher-risk MDS patients up to the age of 75 years. One common approach to "bridge" higher-risk MDS from the time of diagnosis to transplantation is a treatment with hypomethylating agents such as azacitidine due to its anticipated low toxicity profile. Alternative strategies are intensive 7+3 chemotherapy with anthracycline and cytarabine or direct and immediate transplantation. By this strategy the time interval for donor search can be significantly prolonged leading to a higher proportion of success.Nevertheless, not every patient initially eligible for transplantation undergoes this procedure subsequently. A direct prospective comparison of different therapeutic approaches as outlined above versus CPX-351 prior to alloHCT has not been performed so far and is subject of the PALOMA trial. We hypothesize that CPX-351 will lead to higher and more durable response rates including a more favourable safety profile and long-term outcome compared to currently used conventional care regimens approaches prior to alloHCT.

Eligibility

Yes No Not Sure

Inclusion Criteria

Male and female adult patients, 18-75 years of age
Diagnosis of high risk MDS including oligoblastic non-proliferative (WBC <13 Gpt/l) AML up to 29% of bone marrow blasts
Availability of BM blast count from central morphology
Bone marrow blasts 5%
IPSS score intermediate or high
alloHCT intended within the next 6 months
ECOG performance status of 0 or 1
Signed informed consent
Laboratory values fulfilling the following
Serum creatinine < 2.0 mg/dL
Serum total bilirubin < 2.0 mg/dL
Serum alanine aminotransferase or aspartate aminotransferase < 3 times the ULN
Cardiac ejection fraction (LVEF) 50% by echocardiography
Contraception
Female subjects of childbearing potential must agree to use a medically acceptable method of contraception for at least 2 months prior to the first dose of CPX-351 and consent of female patients to use a medically acceptable method of contraception throughout the entire study period and for 6 months following the last dose of CPX-351. Medically acceptable methods of contraception that may be used by the patient include abstinence, diaphragm and spermicide, intrauterine device (IUD), condom and vaginal spermicide, hormonal contraceptives (patients must be stable on hormonal contraceptives for at least the prior 3 months), surgical sterilization, or post-menopausal (2 years of amenorrhea). Medically acceptable methods of contraception that may be used by the male partner of a female patient are condom and spermicide or vasectomy (>6 months prior to Day-1) and are to be used throughout the entire study period and for 6 months following the last dose of CPX-351
Male patients must be willing to refrain from sperm donation for 6 months following the last dose of CPX-351 and must use adequate contraception throughout the entire study period and for 6 months following the last dose of CPX-351
Combined oral contraceptive pills are not recommended. It is recommended that during the study two medically accepted methods of contraception (e.g. as hormonal contraceptive methods along with a condom) apply

Exclusion Criteria

Patients with history of myeloproliferative neoplasms (MPN) (defined as a history of essential thrombocytosis or
polycythemia vera, or idiopathic myelofibrosis prior to the diagnosis of AML) or combined MDS/MPN are not eligible
WHO-2016 defined AML entities: AML with t(15;17), PML-RARA; AML with t(8;21), RUNX1-RUNX1T1, AML with inv(16)/t(16;16), CBF-MYH11; AML with biallelic CEBPA mutation; AML with mutated FLT3 or NPM1
Clinical evidence of active CNS leukemia
Patients with a "currently active" second malignancy other than non-melanoma skin cancers. Patients are not considered to have a "currently active" malignancy if they have completed therapy and are considered by their physician to be at less than 30% risk of relapse within one year
Any major surgery or radiation therapy within four weeks prior screening
Patients with prior treatment of either CPX-351, hypomethylating agents, cytarabine or intensive chemotherapy for high-risk MDS or AML
Patients with prior cumulative anthracycline exposure of greater than 368 mg/m2 daunorubicin (or equivalent)
Any serious medical condition, laboratory abnormality or psychiatric illness that would prevent obtaining informed consent
Patients with myocardial impairment of any cause (e.g. cardiomyopathy, ischemic heart disease, significant valvular dysfunction, hypertensive heart disease, and congestive heart failure) resulting in heart failure by New York Heart Association Criteria (NYHA Class III or IV staging)
Active or uncontrolled infection. Patients with an infection receiving treatment (antibiotic, antifungal or antiviral treatment) may be entered into the study but must be afebrile and hemodynamically stable for 72 hrs
Current evidence of invasive fungal infection (blood or tissue culture); patients with recent fungal infection must have a subsequent negative cultures to be eligible; known HIV (new testing not required) or evidence of active hepatitis B or C infection (with rising transaminase values)
Hypersensitivity to cytarabine, daunorubicin or liposomal products
History of Wilson's disease or other copper-metabolism disorder
Female patients who are pregnant or lactating
