A Study to Investigate Treatment of HU and VPA, or 6-MP and VPA in Unfit AML/HR-MDS Patients

Recruiting now · Phase 1/Phase 2

Conditions studied: Acute Myeloid Leukemia, Adult, Myelodysplastic Syndromes, Adult

In brief

The purpose of this study is to investigate the safety, tolerability, and preliminary efficacy of the combination treatment of hydroxyurea capsules and valproic acid capsules, or the combination treatment of 6-mercaptopurine tablets and valproic acid capsules in male and female patients aged 18 years or older with acute myeloid leukemia or high- risk myelodysplastic syndrome. The population to be studied is newly diagnosed AML patients who are considered unfit for standard induction chemotherapy, HR-MDS unfit/ineligible for standard treatment, and relapsed/refractory AML/HR-MDS patients who are considered unfit for standard therapy ,or are, for some reason, ineligible for another type of therapy. Clinically, hydroxyurea, valproic acid and 6-mercaptopurine are historically very well-known therapeutic agents with low toxicity profiles. The rationale for this study is that the combination of these drugs with low toxicity will be well tolerated in elderly AML patients with comorbidities, or lower performance status. This combination could have a beneficial therapeutic effect on overall survival and contribute to a better quality of life.

You may not qualify if…

• Participants are excluded from the study if any of the following criteria apply:
• Patients on treatment for AML (any anti-leukemic therapy including investigational agents) or treated less than 2 weeks before inclusion.
• Concurrent history of active malignancy in the past six months prior to diagnosis except for
• basal and squamous cell carcinoma of the skin
• in situ carcinoma of the cervix
• Concurrent severe and/or uncontrolled medical condition (e.g. uncontrolled diabetes, infection, hypertension, pulmonary disease et cetera) at the investigators discretion.
• Breastfeeding women

• unstable cardiac arrhythmias
• SARS-CoV-2 infection < 7 days or Covid-19-vaccine < 7 days from study onset
• Patients with a history of non-compliance to medical regimens or who are considered unreliable with respect to compliance.
• Patients with any serious concomitant medical condition that could, in the opinion of the investigator, compromise participation in the study.
• Patients with senile dementia, mental impairment or any other psychiatric disorder that prohibits the patient from understanding and giving informed consent.
• Current concomitant chemotherapy, radiation therapy, or immunotherapy other than as specified in the protocol.
• Known hypersensitivity to study medications or its excipients.
• Any psychological, familial, sociological, and geographical condition potentially hampering compliance with the study protocol and follow-up schedule.
