Trial ID Title Status Sponsor Phase Start Date Summary
NCT00843882 ↗ Lenalidomide With or Without Epoetin Alfa in Treating Patients With Myelodysplastic Syndrome and Anemia Active, not recruiting National Cancer Institute (NCI) Phase 3 2009-01-29 This randomized phase III trial studies lenalidomide to see how well it works with or without epoetin alfa in treating patients with myelodysplastic syndrome and anemia. Lenalidomide may stop the growth of myelodysplastic syndrome by blocking blood flow to the cells. Colony stimulating factors, such as epoetin alfa, may increase the number of immune cells found in bone marrow or peripheral blood. It is not yet known whether lenalidomide is more effective with or without epoetin alfa in treating patients with myelodysplastic syndrome and anemia.
NCT03598582 ↗ Biological Predictive Factors of Response to ESA in Low Risk MDS Patients Completed Association pour la recherche sur les Affections Malignes en Immunologie Sanguine Phase 4 2013-01-01 In this trial, the investigators would like to understand why a small percentage of patients will be refractory to ESA (independently of International prognostic scoring system (IPSS) and % of blasts). In a retrospective study of the "Groupe Francophone des Myélodysplasies (GFM)" , the investigators showed that about 43% of patients are refractory or will relapse after initial response to ESA and it has been shown that these patients have a poorer survival. The investigators plan to give a 12-week treatment of Epoetin alfa or zeta in low risk MDS patients and measure different biological factors to predict response to ESA: - evaluation by flow cytometry before and after treatment of the degree of dyserythropoiesis and dysgranulopoiesis which could explain the primary resistance or loss of response of a subset of patients, - screening by molecular biology of predictive factors of response to ESA, - Iron homeostasis will be measured via hepcidin, GDF-15 and ferritin levels.

RETACRIT: Clinical Trials, Market Analysis, and Projections

Introduction to RETACRIT

RETACRIT, also known as epoetin alfa-epbx, is a biosimilar of the reference product epoetin alfa (Epogen/Procrit), used to treat anemia associated with chronic kidney disease (CKD) and chemotherapy-induced anemia. Here, we will delve into the clinical trials, market analysis, and future projections for this drug.

Clinical Trials Overview

The clinical development program for RETACRIT included several key studies to establish its biosimilarity to the reference product.

Study EPOE-10-13

This study was a comparative efficacy and safety trial involving 320 adult subjects with CKD on hemodialysis. Participants were randomized to receive either RETACRIT or Epogen/Procrit subcutaneously for up to 16 weeks. The study found no clinically meaningful differences between the two treatments in terms of mean weekly hemoglobin (Hb) levels and the dose required to maintain target Hb levels[1][4].

Study EPOE-10-01

This study involved 612 adult subjects with CKD on hemodialysis and compared the intravenous administration of RETACRIT with Epogen/Procrit over 24 weeks. Similar to the previous study, it concluded that there were no significant differences in mean weekly Hb levels and the dosage required to maintain these levels between the two treatments[1][4].

Additional Studies

Other studies included patients receiving chemotherapy and those with anemia caused by kidney problems. These studies also demonstrated that RETACRIT was as effective as the reference product, Eprex/Erypo, in correcting and maintaining red blood cell counts[4].

Safety and Efficacy

The clinical trials for RETACRIT have consistently shown that it is safe and effective, with a comparable quality, safety, and efficacy profile to the reference product.

  • Haemoglobin Levels: Studies have shown that RETACRIT maintains haemoglobin levels similar to those of the reference product, with levels around 11.4-11.6 g/dl during the treatment period[1][4].
  • Dosage: The dose of epoetin required to maintain target Hb levels was similar between RETACRIT and the reference product[1][4].
  • Transfusion Incidence: There were no statistically significant differences in the incidence of transfusions between the treatment groups[1].

Market Analysis

Current Market Share

RETACRIT has been gaining traction in the market since its approval. As of recent reports, the volume market share of epoetin alfa products shows that RETACRIT, along with the reference products Epogen and Procrit, continues to be a significant player.

  • Volume Market Share: RETACRIT, along with Epogen and Procrit, maintains a combined share of approximately 70% in the epoetin alfa market[5].

Average Sales Price (ASP)

The ASP of RETACRIT has been competitive, contributing to its market share.

  • ASP Trends: The ASP of RETACRIT has been trending lower compared to the reference products, making it an attractive option for cost-conscious healthcare systems[5].

Regulatory Environment

The approval and marketing authorization of RETACRIT have been facilitated by regulatory bodies such as the European Medicines Agency (EMA) and the U.S. FDA.

  • EMA Approval: RETACRIT received marketing authorization from the EMA in 2007, validating its biosimilarity to the reference product Eprex/Erypo[4].

Market Projections
