What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.

Summary

This study tests a combination of two drugs—luspatercept and erythropoietin (EPO)—for people with a low-risk form of myelodysplastic syndrome (MDS) that does not involve ring sideroblasts. Participants must have already tried EPO alone without success or be unable to take it. The goal is to find the best dose and see if the combination works better than luspatercept alone at improving blood counts. About 150 adults will take part in this early-phase trial.

Inclusion Criteria: Patients must meet all of the following criteria to participate in the study: * Myelodysplastic syndrome according to current WHO classification * Age ≥ 18 years * Patients with lower risk MDS according to IPSS classification (LOW, INT-1) without RS who failed to achieved a response or who subsequently relapse after ESA (at least 60000 U EPO-a over at least 12weeks or equivalent), without disease progression (or ineligible to ESA defined by EPO \> 500 UI/l) * Hemoglobin \< 9 gr/dl or Transfusion dependant (at least 3 RBCs in 16 wk in at least 2 transfusion episodes) * Non del(5q) syndrome * Adequat renal function, defined by creatinine less than 1.5 times the upper limit of normal, creatinine clearance ≥ 40 mL/min (MDRD formula). * Adequat liver function, defined by total bilirubin and transaminases less than 1.5 times the upper limit of normal. * Patient is not known to be refractory to platelet transfusions. * Written informed consent. * Patient must understand and voluntarily sign consent form. * Patient must be able to adhere to the visit schedule as outlined in the study and follow protocol requirements. * ECOG performance status 0-2 at the time of screening. * A FCBP (female of childbearing potential) for this study was defined as a sexually mature woman who: (1) had not undergone a hysterectomy or bilateral oophorectomy; or (2) had not been naturally postmenopausal (amenorrhea following cancer therapy did not rule out childbearing potential) for at least 24 consecutive months (ie, has had menses at any time in the preceding 24 consecutive months). A FCBP participating in the study must: * Have had 2 negative pregnancy tests as verified by the investigator prior to starting IP (unless the screening pregnancy test was done within 72 hours of Cycle 1 Day 1). She must have had agreed to ongoing a monthly pregnancy testing during the course of the study and after EOT * If sexually active, agreed to have used, and been able to comply with, highly effective contraception\*\* without interruption, 5 weeks prior to starting IP, during treatment with IP (including dose interruptions), and for 12 weeks after discontinuation of IP. * \*\* Highly effective contraception was defined in this protocol as the following (information also appeared in the ICF): Hormonal contraception (eg, birth control pills, injection, implant, transdermal patch, vaginal ring), intrauterine device, tubal ligation (tying your tubes), or a partner with a vasectomy * Male subjects must: Have agreed to use a condom, defined as a male latex condom or nonlatex condom NOT made out of natural (animal) membrane (eg, polyurethane), during sexual contact with a pregnant female or a FCBP while participating in the study, during dose interruptions, and for at least 12 weeks following IP discontinuation, even if he had undergone a successful vasectomy Exclusion Criteria: A patient meeting any of the following criteria is not eligible to participate in the study: * Severe infection or any other uncontrolled severe condition. * Uncontrolled hypertension * Significant cardiac disease - NYHA Class III or IV or having suffered a myocardial infarction in the last 6 months. * del(5q) syndrome * Use of investigational agents within 30 days or any anticancer therapy (including IMiD) within 2 weeks before the study entry with the exception of hydroxyurea. The patient must have recovered at least a grade 1 from all acute toxicity from any previous therapy. * Use of EPO within 4 weeks before the study entry * Active cancer, or cancer during the year prior to trial entry other than basal cell carcinoma, or carcinoma in situ of the cervix or breast. * Patient already enrolled in another therapeutic trial of an investigational drug. * Known HIV infection or active hepatitis B or C. * Women who are or could become pregnant or who are currently breastfeeding. * Any medical or psychiatric contraindication that would prevent the patient from understanding and signing the informed consent form. * Patient eligible for allogeneic stem cell transplantation. * Known allergies to luspatercept or EPO or any of its excipients. * No affiliation to a health insurance system.
