Brief summary: This is a randomised, double-blind, placebo-controlled multiple ascending single study. It is hypothesised that at least dose of DS-1093a will be safe and tolerable over a 2-week treatment period and will result in increases in reticulocyte count and haemoglobin concentrations in healthy male volunteers


Eligibility criteria: Inclusion Criteria:

* Healthy male subjects, aged 18-45 years.
* A body mass index (BMI, or Quetelet index) in the range 18.0-30.0
* Willing to use a reliable method of contraception during the trial, and for 4 months afterwards
* Sufficient intelligence to understand the nature of the trial and any hazards of participating in it. Ability to communicate satisfactorily with the Investigator and to participate in, and comply with the requirements of, the entire trial.
* Willingness to give written consent to participate after reading the information and consent form (ICF), and after having the opportunity to discuss the trial with the Investigator or his delegate.
* Willingness to give written consent to have data entered into The Overvolunteering Prevention System.

Exclusion Criteria:

* Clinically relevant abnormal medical history, physical findings, electrocardiogram (ECG), or laboratory values at the pre-trial screening assessment that could interfere with the objectives of the trial or the safety of the volunteer.
* Presence of acute or chronic illness or history of chronic illness (particularly hypertension, seizures, kidney disease or liver disease, including known or newly discovered Gilbert's syndrome) sufficient to invalidate the volunteer's participation in the trial or make it unnecessarily hazardous.
* Impaired endocrine, thyroid, hepatic, respiratory or renal function, diabetes mellitus, coronary heart disease, or history of psychotic mental illness.
* Presence or history of malignant disease, other than basal cell carcinoma that was successfully treated at least 5 years ago.
* Any medical history that, in the opinion of the Investigator, is suggestive of a significant bleeding or coagulation risk.
* History of venous or arterial thrombosis or embolic disease.
* History of gastric or duodenal ulcer.
* History of treatment with, or use of, an erythropoiesis stimulating agent (e.g. EPO).
* Blood pressure (BP) and heart rate in supine position at the screening examination outside the ranges 90-140 mm Hg systolic, 40-90 mm Hg diastolic; heart rate 40-100 beats/min.
* Haemoglobin concentration of \< 129 g/L, platelets outside the normal reference ranges at the screening examination, or evidence of iron deficiency based on serum iron and ferritin levels.
* Surgery (e.g. stomach bypass) or medical condition that might affect absorption of medicines.
* Presence or history of significant hypersensitive or allergic reaction to any drug, except penicillin.
* Use of a prescription medicine or a strong inducer or inhibitor of cytochrome P450 enzymes, during the 30 days before the first dose of trial medication; use of any other over-the-counter medicine, with the exception of acetaminophen (paracetamol), during the 7 days before the first dose of trial medication.
* Participation in another clinical trial of a new chemical entity or a prescription medicine within the previous 3 months, or unwilling to abstain from participating in other clinical trials during the study and for 3 months after receipt of the final dose of trial medication.
* Positive test for hepatitis B, hepatitis C, HIV 1 \& HIV 2.
* Abuse of drugs or alcohol during the 2 years before the first dose of trial medication.
* Evidence of drug or alcohol abuse at screening, or intake of more than 21 units of alcohol weekly.
* Use of tobacco or nicotine-containing products during the 3 months before the first dose of trial medication.
* Loss of more than 400 mL blood, or donation of blood, plasma, platelets, or any other blood components, during the 3 months before the trial, or unwilling to abstain from donating during the study and for 3 months after receipt of the final dose of trial medication.
* Possibility that the volunteer will not cooperate with the requirements of the protocol.
* Objection by General Practitioner (GP) to volunteer entering trial.
