Trial Summary

Will I have to stop taking my current medications?

The trial requires participants to stop taking hydroxyurea for 30 days before the first dose of the study drug. For other medications, the protocol does not specify, so it's best to discuss with the trial team.

Is the drug Motixafortide a promising treatment for Sickle Cell Disease?

The provided research articles do not contain information about Motixafortide or its effectiveness in treating Sickle Cell Disease, so we cannot determine if it is a promising treatment based on this data.12345

What is the purpose of this trial?

This study is being done to see if the study drug, motixafortide, is safe in participants with sickle cell disease (SCD). Investigators also want to see if the drug will help the body increase the number of stem cells that can be collected for possible future transplant use.PRIMARY OBJECTIVE* To characterize the safety and tolerability of motixafortide in participants with SCD as determined by the incidence of adverse events (AEs).SECONDARY OBJECTIVES* To characterize the efficacy of a single dose (Part A) or two doses (Part B) of motixafortide for hematopoietic stem cell (HSC) mobilization and apheresis collection in participants with SCD as determined by the yield of CD34+ cells (CD34+ cells/kg).* To measure the mobilization effects of single-day (Part A) or daily dosing (Part B) dosing with motixafortide in the peripheral blood in participants with SCD as determined by peak peripheral blood CD34+ counts* To recommend a phase 2 dosing strategy based on safety, efficacy, and mobilization effects

Eligibility Criteria

This trial is for individuals with sickle cell disease (SCD) or sickle cell anemia. It's designed to test if a drug called motixafortide can safely increase the number of stem cells in their blood, potentially helping future transplant treatments.

Inclusion Criteria

My liver tests are within the required range.
I have a confirmed diagnosis of sickle cell disease.
I either have a central line in place or can undergo apheresis without needing a new central line.

  • Motixafortide
Trial Overview The study examines the safety and effectiveness of motixafortide in increasing stem cells for collection. Participants will receive either one dose (Part A) or two doses (Part B), and researchers will track how many stem cells are mobilized.

Experimental Treatment
Group I: Treatment-Arm B-Two Daily DosesExperimental Treatment1 Intervention
Part B: Participants who enroll later in the study will be assigned to Part B. Part B participants will get two doses of the study drug and two stem cell collection processes over two days (one on each day).
Group II: Treatment-Arm A-Single DoseExperimental Treatment1 Intervention
Part A: Participants who enroll early will be assigned to Part A. Part A participants will get one dose of the study drug and one stem cell collection process.

Findings from Research

A post hoc analysis of patients with severe hemophilia B receiving rFIXFc prophylaxis showed significant reductions in pain, with fewer patients experiencing painful swellings (64% vs. 44%) and painful joints (44% vs. 28%) at the end of the study compared to baseline.
Patients reported improved physical activity, with a notable decrease in those avoiding sports due to hemophilia (47% vs. 27%) and an increase in participation in sports comparable to the general population (52% vs. 37%).

In a study involving 33 male patients with severe hemophilia A, Safacto® demonstrated a significant increase in plasma FVIII activity, reaching an average of 88.84 IU/dl, compared to 100.09 IU/dl for Xyntha®, indicating effective clotting factor replacement.
Both Safacto® and Xyntha® were found to be safe, with no allergic reactions or adverse effects reported, suggesting that Safacto® is a viable alternative to Xyntha® for managing hemophilia A.

MonoFIX-VF is a safe and effective treatment for patients with factor IX deficiency (hemophilia B), having replaced Prothrombinex-HT in Australia.
In a study involving four subjects treated for 10 bleeding episodes, including five surgical procedures, MonoFIX-VF demonstrated positive haemostatic effects when administered by continuous infusion.
