The objective of this study is to determine the safety, dose tolerance, pharmacokinetics and pharmacodynamics of pyrimethamine in intermediate / high-risk / relapsed or azanucleoside-refractory MDS within the confines of a phase I study. Pyrimethamine self-administered by participants orally once per day in morning with food. Phase 1 study will start at dose of 50 mg once per day. (NOTE: For participants at dose level of 50mg, the dose reduction, if needed is 25 mg.) Intra-patient dose escalation is permitted (not beyond the highest dose allowed) if Complete Remission/Response (CR) is not reached in week 1 of Cycle 3 and there is no significant toxicity. (NOTE: In this study, the term "intra-patient" indicates within each participant and not between different participants; i.e., dose escalation will be done within each individual participant.) The decision to escalate intra-patient doses will be based on safety and dose tolerance assessments made at the end of one treatment cycle (28 days of continuous drug administration) for all 6 participants. Dose-limiting toxicity (DLT) is defined as the occurrence of two consecutive grade 2 or 3 serious adverse events (SAEs) not recovered within 24 hours at a given dose. MTD will be defined as the dose where no DLT is observed among three consecutive participants, or no more than one DLT among six participants. Participants will be treated initially for one 28-day cycle followed by a toxicity evaluation - Toxicity and adverse effect assessments will be made on Day 1 and Day 28 of every cycle of therapy.
