About this study

The primary objective of this study is to determine the safety and tolerability of combined abaloparatide and bevacizumab in patients with Myelodysplastic Syndromes (MDS). A secondary objective is to determine the response to treatment (based on bone marrow and peripheral blood findings). A tertiary objective is to determine the impact of therapy on health-related quality of life (HRQOL) and patient-reported outcomes (PRO). A quaternary (scientific) objective is to determine the impact of treatment on both hematopoietic and stromal cell populations within the bone marrow of MDS patients.

Read the detailed description

The main objective of this study is to determine the safety and tolerability of combined abaloparatide + bevacizumab in MDS patients. This will be a single center, single arm, phase 1 trial in MDS patients. In cycle 1, patients will be treated with single-agent, subcutaneous (SQ) abaloparatide at a dose of 80 mcg/day for 28 days. This will enable the investigator to monitor for any potential toxicities of single-agent abaloparatide in the MDS patient population. Following cycle 1, patients will have a bone marrow aspirate to determine the impact of abaloparatide treatment on bone marrow stromal cell and hematopoietic cell populations. In cycles 2-4 (each cycle is 28 days), patients will be treated with SQ abaloparatide at a dose of 80 mcg/day and intravenous (IV) bevacizumab 5 mg/kg on days 1 and 15. At the end of study, patients will have a bone marrow aspirate and biopsy to assess disease response and to determine the impact of combined abaloparatide + bevacizumab on bone marrow stromal cell and hematopoietic cell populations. After completion of trial therapy, another bone marrow aspirate and biopsy will be done 3 months later to assess the delayed impact of treatment. The investigator has chosen a phase 1 trial design because this combination has not been previously evaluated for toxicity. Since safe and effective doses of both abaloparatide and bevacizumab have already been identified and both drugs are Food and Drug Administration (FDA)-approved, the investigator does not feel there is a need to dose-escalate. The investigator will carefully monitor for therapy-limiting toxicities (TLTs) throughout the course of the study and impose an early stopping rule for toxicity. To monitor for TLTs, patients will have laboratory tests weekly and clinic visits every other week throughout the course of the trial. TLT is defined in the protocol with grading of adverse events defined by the NCI Common Toxicity Criteria for Adverse Events (CTCAE) version 5.0. Response will be defined according to 2006 IWG working criteria for MDS. Patients who have achieved complete remission (CR), partial remission (PR), marrow CR, and/or hematologic improvement at any time during the 7 month trial period will be considered responders. Eligible subjects will have a diagnosis of MDS or non-proliferative chronic myelomonocytic leukemia (CMML) based on 2016 world health organization (WHO) criteria, and associated signs of bone marrow failure characterized by at least some degree of cytopenia involving at least one cell line such as anemia, thrombocytopenia or leukopenia. Patients will not be allowed to receive concurrent active chemotherapy or growth factors.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Proportion of patients who experience a therapy-limiting Toxicity (TLT)

    Safety of this therapy will be based on subjects who complete at least two cycles, experiencing both study drugs for at least one cycle. TLT is defined as any serious AEs considered at least possibly due to abaloparatide and/or bevacizumab, occurring at any time from the initial dose of study treatment, with severity graded according to the NCI Common Terminology Criteria for Adverse Events (CTCAE), Version 5.

    Measured: 7 months

Secondary outcomes (1)
  1. Proportion of patients who responded to therapy

    In this study, patients who have achieved complete remission (CR), partial remission (PR), marrow CR, and/or hematologic improvement will be considered responders according to the International Working Group (IWG) Response Criteria and Modified IWG Response Criteria for Hematological Improvement. The overall rate of response will be estimated among all subjects who received at least one dose of any study drug.

    Measured: 7 months

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing abaloparatide and bevacizumab in people with Myelodysplastic Syndromes and Chronic Myelomonocytic Leukemia, run by University of Rochester at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 21 inclusion and 31 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 23 Jan 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Proportion of patients who experience a therapy-limiting Toxicity (TLT) (time frame: 7 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Jan 2023.
