Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
The sponsor is the organization or person who oversees the clinical study and is responsible for analyzing the study data.

EVI-3 is a phase 2 international, multicentre, randomized, parallel-group, placebo-controlled, double-blind study of the efficacy and safety of oral vitamin C supplement in combination with azacitidine (AZA) in patients with higher-risk myeloid malignancies with or without mutations in genes recurrently affected in myeloid malignancies. Treatment allocation is in 1:1 ratio (vitamin C vs.#46; placebo) by block randomization stratified by clinical site. Study entry is staggered. Patients are randomized to either oral vitamin C 1000 mg daily or placebo from start of AZA treatment until end of study (EOS) or until AZA treatment is discontinued at the discretion of the treating physician, whichever occurs earlier. The accrual time is estimated to 48 months and 6 months follow-up, thus, maximum treatment duration will be approximately 54 months. A total of 196 patients is planned for enrollment. Study visits are scheduled at baseline, after 1st AZA treatment cycle, after 6 AZA treatment cycles, and, if AZA treatment is continued, at EOS or end of AZA treatment. Evaluations at study visits include bone marrow investigation, peripheral blood tests, patient-reported outcome measures, adverse events and compliance. Bone marrow aspirate and peripheral blood will be collected for biobank at each study visit. All patients will undergo follow-up once yearly from EOS. Follow-up will include information on duration of AZA therapy, survival and disease progression from myelodysplastic syndrome (MDS) or chronic myelomonocytic leukemia (CMML) to acute myeloid leukemia (AML), if diagnosed following a clinical indication for a bone marrow test.
Experimental: Vitamin C
Oral vitamin C (ascorbic acid) will be given in a dose of 1000 mg daily (two capsules of 500 mg once daily) starting day 1 in the 1st azacitidine (AZA) cycle (D1/C1) and continuing until discontinuation of AZA or end of study, whichever occurs earlier.
Placebo Comparator: Placebo
Placebo will be administered orally as two capsules once daily that look and taste identical to the capsules containing vitamin C. Treatment will start day 1 in the 1st azacitidine (AZA) cycle (D1/C1) and continuing until discontinuation of AZA or end of study, whichever occurs earlier. The content of the placebo capsules is glucose monohydrate, potato starch, gelatin, magnesium stearate and talc.
Dietary Supplement: - Vitamin C
Oral vitamin C (ascorbic acid) 1000 mg daily will be administered from day 1 in the 1st AZA cycle (D1/C1) and continued until discontinuation of AZA or EOS as combination treatment.
Dietary Supplement: - Placebo
Placebo capsules (two capsules once daily) will be administered from day 1 in the 1st AZA cycle (D1/C1) and continued until discontinuation of AZA or EOS.
