A Phase 2 Open-Label Study to Evaluate Etavopivat for the Treatment of Anemia in Patients With Myelodysplastic Syndromes (MDS) ETAVOPIVAT

What's the purpose of this trial?

The purpose of this study is to evaluate the safety and efficacy of etavopivat (FT-4202) for the treatment of anemia in adult patients with very low risk, low risk, or intermediate risk MDS.

This trial is currently open and accepting patients.

What will happen during the trial?

You may be able to join this trial if you:

The following criteria is a partial list of reasons why patients may be eligible to participate in this clinical trial. Further evaluation with a medical professional is required.

2. Age ≥ 18 years at time of first dose.
3. Patients, if female and of childbearing potential, must agree to use acceptable methods of contraception and agree not to donate ova from study start to 90 days after the last dose of study drug, and who if male are willing to use acceptable methods of contraception and agree not to donate sperm, from study start to 90 days after the last dose of study drug.
4. Documented diagnosis of idiopathic/de novo MDS according to World Health Organization (WHO) classification that meets the IPSS-R classification of very low, low, or intermediate risk disease, and:

* \< 5% blasts in bone marrow based on local pathology review
* \< Intermediate risk cytogenetic abnormalities per IPSS-R
5. Anemia defined as:

* Non-transfusion dependent (NTD): Subjects with mean Hb concentration \< 10.0 g/dL of 2 measurements (1 performed within 3 days prior to Day 1 and the other performed 7 to 28 days prior to Day 1, not influenced by RBC transfusion within 7 days of measurement) and \< 3 RBC transfusions for anemia in the prior 16 weeks before Day 1 of etavopivat dosing

* Transfusion dependent (TD): Subjects having received ≥ 3 units of RBCs for the treatment of anemia within 16 weeks prior to Day 1
6. Serum erythropoietin level \> 200 U/L, OR, if ≤ 200 U/L, subject is non-responsive, refractory, or intolerant to erythropoiesis-stimulating agents, or erythropoiesis-stimulating agents are contraindicated or unavailable.
7. ECOG performance status of ≤ 2
8. Subject is non-responsive, refractory, or intolerant to luspatercept, or luspatercept is contraindicated or not indicated.
9. No alternative treatment options are available and/or appropriate for the subject, at the discretion of the investigator.
10. Patient is willing and able to adhere to the study visit schedule and other protocol requirements


\[MDS History\]

1. MDS associated with del 5q cytogenetic abnormality and known TP53 abnormality
2. Therapy-associated MDS (eg. t-MDS) that is known to have arisen as the result of chemical injury or treatment with chemotherapy and/or radiation for other diseases
3. Known history of acute myeloid leukemia (AML)

\[Medical Conditions\]
4. Female who is breast feeding or pregnant
5. Known clinically significant anemia due to iron, vitamin B12, or folate deficiencies, or autoimmune or hereditary hemolytic anemia, or gastrointestinal bleeding
6. Absolute neutrophil count \< 500/µL (0.5 x 10\^9/L)
7. Platelet count \< 50,000/µL (50 x 10\^9/L) without transfusion support within 2 weeks
8. Hepatic dysfunction characterized by:

* Alanine aminotransferase (ALT) \> 5.0 × upper limit of normal (ULN)
* Total bilirubin \> 3.0 × ULN
* History of cirrhosis
9. Severe renal dysfunction (estimated glomerular filtration rate at the Screening visit; calculated by the local laboratory \< 30 mL/min/1.73 m\^2 ) or on chronic dialysis.
10. Patients with clinically significant and active bacterial, fungal, parasitic, or viral infection.

* Patients with acute bacterial, fungal, parasitic, or viral infection requiring systemic therapy should delay Screening/ enrollment until active therapy has been completed.
* Patients with acute viral infections without available therapies (eg, coronavirus disease 2019 \[COVID-19\]) should delay Screening/ enrollment until the acute infection has resolved.

Note: Infection prophylaxis is allowed.
11. Known human immunodeficiency virus (HIV) positivity
12. Active infection with hepatitis B virus (hepatitis B surface antigen \[HepBsAg\] and hepatitis B core antibody \[HepBcAb\] positive)
13. Active hepatitis C infection
14. History of malignancy, other than MDS, within the past 2 years prior to treatment Day 1 requiring systemic chemotherapy and/or radiation.

* Patients with malignancy considered surgically cured are eligible (eg, non-melanoma skin cancer, carcinoma in situ of the cervix, or carcinoma in situ of the breast)
* Patients with incidental histologic findings of prostate cancer (T1a or T1b) are eligible
15. History of unstable or deteriorating cardiac or pulmonary disease within 6 months prior to consent including but not limited to the following:

* Unstable angina pectoris or myocardial infarction or elective coronary intervention
* Heart disease, heart failure as classified by the New York Heart Association classification 3 or higher, or significant arrhythmia requiring treatment,
* Pulmonary fibrosis or pulmonary hypertension which are clinically significant ie, ≥ Grade 3 National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 (or higher)
16. Uncontrolled hypertension, defined as repeated elevation of diastolic blood pressure ≥ 100 mmHg despite adequate treatment
17. Any condition affecting drug absorption, such as major surgery involving the stomach or small intestine (prior cholecystectomy is acceptable).

\[Prior/Concomitant Therapy\]
18. Prior treatment with azacitidine (injectable or oral) or decitabine
19. Use of erythropoietin, other hematopoietic growth factor treatment or lenalidomide within 30 days of starting study treatment or anticipated need for such agents during the study.
20. Prior use of luspatercept:

* NTD patients must not have received luspatercept within 30 days prior to Day 1 treatment
* TD patients must not have received luspatercept within 16 weeks prior to Day 1 treatment
21. Receiving or use of concomitant medications that are strong inducers of cytochrome P450 (CYP)3A4/5 (see Appendix F) within 2 weeks of starting study treatment or anticipated need for such agents during the study.
22. Prior allogeneic or autologous stem cell transplant
23. Initiation of a new chelation therapy within 3 months before the first dose of study treatment.

\[Prior/Concurrent Clinical Study Experience\]
24. Participated in another clinical trial of an investigational agent (or medical device) within 30 days or 5 half-lives of date of informed consent, whichever is longer, or is currently participating in another trial of an investigational agent (or medical device).

\[Other Exclusions\]
