ExclusionCriteria 
Details  1. Other causes of anemia such as iron deficiency. Subjects must have documented marrow iron stores or serum ferritin >50 ng/ml. If marrow iron store is not available, the transferrin saturation must be > 20% or a serum ferritin > 50 ng/ mL.
2. Clinically significant anemia resulting from B12 or folate deficiencies, autoimmune or hereditary hemolysis, or gastrointestinal bleeding.
3. Women must not be pregnant or breastfeeding. Females of childbearing potential should have a negative pregnancy test (sensitivity of at least 50 mIU/mL) within 28 days of first dosing and negative urine pregnancy test on day 1 of cycle 1.
4. Presence of concomitant intercurrent illness, or any condition which in the opinion of the Investigator, would compromise safe participation in the study, e.g. active
severe infection, uncontrolled hypertension, uncontrolled seizure, unstable angina pectoris, new onset of exacerbation of a cardiac arrhythmia
5. Secondary MDS, defined as MDS that is known to have arisen as a result of chemical injury or treatment with chemotherapy and/or radiation for other diseases.
6. Treatment with cytotoxic chemotherapeutic agents or experimental agents for the treatment of MDS within 4 weeks of study treatment.
7. Chronic use of systemic corticosteroids for comorbid or study disease condition with in last 4 weeks of study treatment
8. Prior history of malignancy other than MDS (except non-melanoma skin cancer or carcinoma in situ of the cervix or breast) unless the subject has been free of disease for > 3 years.
9. Subject has undergone a stem cell, bone marrow or solid organ transplant
10. Subjects with positive serology for Hepatitis B Virus (HBV), Hepatitis C Virus (HCV), or Human Immunodeficiency Virus (HIV) and subjects with presence of viral load suggestive of active disease.
11. Prior treatment with disease modifying agents such as hypomethylating agents, or immunosuppressive therapy or experimental agents other than growth factor for MDS.
12. Participation in any clinical study within 90 days before the first dose of Investigational Product.
13. Loss of greater than or equal to 350 ml of blood within 90 days before the first dose of Investigational Product.

Brief Summary
Modification(s)  

This study is an open-label, Phase 2a clinical trial evaluating the efficacy and safety of HT-6184 in subjects with very low, low or intermediate risk MDS who are refractory, intolerant of or ineligible for treatment with an ESA.

 

HT-6184 2 mg capsule will be self-administered orally once a day (QD)  for 5 days , approximately at the same time each day followed by a 2 days drug holiday.

 

Each treatment cycle consists of 28 days. Subjects will be evaluated for safety if they receive at least one dose of study drug, utilizing an intention-to-treat approach for study analysis.

 

 

 

Subjects will be monitored at each cycle for drug tolerance, safety and hematological response. Final response assessment will occur after 16 weeks of study treatment using IWG 2018 criteria (refer Appendix B).

 

 

 

Responding subjects may continue treatment thereafter until evidence for loss of response, intolerance or subject’s decision to withdrawal from the study.

 

 

 

Non-responders who experience a reduction in clone size (VAF reduced >30% of baseline) at Week 16 and for whom the investigator feels clinical or emerging hematologic benefit may continue monotherapy for up to 16 additional weeks (Week 32) before hematologic response assessment. Subjects not responding to HT-6184 monotherapy at Week 16 (i.e., those subjects with clonal suppression) will be offered to continue HT-6184 combined with their prior ESA. Dosing with epoetin alfa will be 60,000 units subcutaneously (SC) weekly or darbepoetin alpha 300μg SC at every 2 weeks.

 

Response to and tolerance of the combined regimen will be assessed at study week 32 (i.e., Week 16 combined therapy).

 

 

 

A quality of life (QOL) assessment will be collected at protocol-specified time points from all subjects, using the health-related Quality of Life (QOL-E®) questionnaire.
