Brief Summary

This phase II trial studies the effects of luspatercept with or without hydroxyurea in treating patients with myelodysplastic/myeloproliferative neoplasms with ring sideroblasts and thrombocytosis or unclassifiable with ring sideroblasts. Biological therapies, such as luspatercept, use substances made from living organisms that may stimulate or suppress the immune system in different ways and stop cancer cells from growing. Hydroxyurea may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving luspatercept with or without hydroxyurea may help doctors determine what doses of the combination is safe for patients to take and how the disease responds to the treatment.

Detailed Description

PRIMARY OBJECTIVE:

I. To document the erythroid response rate assessed as per the 2015 International Working Group (IWG) myelodysplastic (MDS)/myeloproliferative neoplasms (MPN) response criteria.

SECONDARY OBJECTIVES:

I. To document response duration, time to acute myeloid leukemia (AML) transformation, AML-free survival (LFS) and overall survival (OS) in patients with MDS/MPN-with ring sideroblasts (RS) and thrombocytosis (T) and MDS/MPN-unclassifiable (U)U with RS.

II. To document safety of luspatercept (luspatercept-aamt) in patients with MDS/MPN-RS-T and MDS/MPN-U with RS.

EXPLORATORY OBJECTIVE:

I. To assess overall health-related quality of life as measured by Hematological Malignancy Specific Patient-Reported Outcome Measure (HM-PRO).

CORRELATIVE RESEARCH OBJECTIVE:

I: To find an effective biomarker of response to luspatercept-aamt.

OUTLINE: Patients are assigned to 1 of 2 cohorts.

COHORT A: Patients receive luspatercept subcutaneously (SC) on day 1. Cycles repeat every 21 days for 6 months in the absence of disease progression or unacceptable toxicity. Patients undergo blood sample collection, bone marrow biopsy and aspirate at baseline and on study.

COHORT B: Patients receive luspatercept SC on day 1 and hydroxyurea orally (PO) on days 1-21. Cycles repeat every 21 days for 6 months in the absence of disease progression or unacceptable toxicity. Patients undergo blood sample collection, bone marrow biopsy and aspirate at baseline and on study.

After completion of study treatment, patients are followed up every 3 months.

Eligibility Criteria

Inclusion Criteria

• Age >= 18 years
• Patients with a World Health Organization(WHO)-defined diagnosis of MDS/MPN-RS-T or MDS/MPN-U with >= 15% RS
• Prior treatment with lenalidomide, hypomethylating agents, immunosuppressive therapy, erythropoietin stimulating agents (ESA) or investigational agent is allowed as long as patients have not received luspatercept-aamt or sotatercept. If there is prior history of investigational agent, there should be an interval equivalent to at least four elimination half-lives of the agent prior to enrollment. Note: For patients who have received prior lenalidomide, hypomethylating agents, or immunosuppressive therapy, there must be >= 6 weeks since the last dose before luspatercept-aamt treatment is started
• Eastern Cooperative Oncology Group (ECOG) performance score of 0, 1 or 2
• Requirement of red blood cell transfusions (>= 2 unit =< 8-weeks prior to registration) OR symptomatic anemia with hemoglobin < 9.5 g/dL OR hematocrit < 30% (as long as there is documentation of adequate iron stores (ferritin > 50 mg/L) =< 5 weeks prior to registration). Symptomatic anemia is defined as fatigue with or without exertion, shortness of breath with or without exertion, or decrease in exercise tolerance
