- Therapeutic Equivalence of Generic Iron Complex Product General Information: Document Type: Sources Sought - FDA-SS-1116099 Release Date: April 19, 2013 Response Date: May 3, 2013 at 4:00pm EST via email to Natalie.Mitchell@fda.hhs.gov Contracting Office Address: Food and Drug Administration, 5630 Fisher Lane, Rockville, Maryland 20857; Attn: Natalie Mitchell, Contract Specialist Description of Services/Supplies: Therapeutic Equivalence of Generic Iron Complex Product CONTRACTING OFFICE U.S. Department of Health and Human Services (DHHS) Food and Drug Administration Agency (FDA) / Office of Acquisitions and Grants Services (OAGS) DESCRIPTION This is a SOURCES SOUGHT NOTICE to determine the availability and capability of small businesses (including certified 8(a), Small Disadvantaged, and HUBZone firms; veteran and service-disabled veteran-owned small businesses, and women-owned small businesses) to evaluate the therapeutic equivalence of generic sodium ferric gluconate iron complex Nulecit TM and its RLD Ferrlecit®. The Contractor's capability statement shall demonstrate the company's ability to meet the following requirements. Please provide a detailed description of your company's (including its teammates, if applicable) experience and demonstrated abilities to deliver the following: Background: Parenteral iron injection products are used to treat anemia, particularly in patients with chronic kidney disease (CKD). There are four types of parenteral iron complex products available in North America: iron sucrose, sodium ferric gluconate, iron dextran, and ferumoxytol. All parenteral iron products are colloids comprising a continuous aqueous medium and particles of carbohydrate protected iron oxyhydroxide. After intravenous administration, iron colloid particles are processed by phagocytes and iron ions are delivered to the lysosomes within the cell as part of the intracellular labile iron pool. The phagocyte uptake and biodistribution of iron complex particles depend upon their physicochemical properties. If iron is not needed immediately, it is stored in the form of ferritin or hemosiderin. When the iron is needed in the body, iron is released from the cell and transferrin binds iron ions and delivers them to their destination. If transferrin is oversaturated or if the iron complex product is so unstable that iron is spontaneously released at a rate that exceeds transferrin binding capacity, non-transferrin bound iron (NTBI) is formed in the plasma. NTBI can be toxic to cells as it acts as a catalyst in the formation of free radicals from reactive oxygen species. In 2011, FDA approved the first generic sodium ferric gluconate iron complex Nulecit TM, an alternative to Ferrlecit® for the treatment of iron deficiency in chronic kidney disease (CKD) patients. The approval standards for generic iron complex products have been controversial. FDA approved sodium ferric gluconate iron complex based on comprehensive physicochemical characterization and clinical plasma pharmacokinetics data whereas European Medicine Agency (EMA) required additional comparative data from non-clinical studies on the time-dependent iron content in the major target to support the sameness of generic and reference iron complex products. Furthermore, since NTBI is not required for measurement in bioequivalence study in US, concerns have been raised regarding generic iron formulations which may have different levels of labile iron, leading to the formation of different amount of NTBI in vivo from those of reference listed drug (RLD). These NTBIs will potentiate oxidative stress and inflammation, then resulting in direct cellular damage and possibly increasing the risk of atherosclerotic disease. The Agency believes that a battery of physicochemical characterization tests including in-vitro labile iron determination would ensure comparable tissue distribution and no more in vivo labile iron leakage from generic formulations than that from RLD. Well controlled, prospective studies that investigate iron tissue distribution in preclinical species and compare NTBI levels between brand and generic in hemodialysis patients may confirm the agency's approved criteria and help address the public concerns. Statement of Work (SOW) or Objectives: The objectives of this requirement is to evaluate the therapeutic equivalence of generic sodium ferric gluconate iron complex Nulecit TM and its RLD Ferrlecit®. Specific aims are: 1) compare reticuloendothelial system (RES) uptake of RLD and generic; 2) compare biodistribution of the RLD and generic in animal models; 3) conduct in-vivo study to compare plasma NTBI levels and oxidative stress after i.v. administration of RLD and generic in healthy subjects or patients. This study is part of post-market surveillance that can help address potential concerns regarding the quality of generic iron complex products and support the Agency's review standards. Below are the detailed descriptions: 1) Conduct in-vitro phagocytosis assays to compare RES uptake of RLD and generic. Since a battery of in vitro characterization tests have proved physicochemical equivalence between Nulecit TM and its RLD Ferrlecit®, the rate and extent of phagocyte uptake of generic and RLD should be similar. 2) Determine the time-dependent iron content in the major target organ (e.g., plasma, RES, target tissues) and compare biodistribution of RLD and generic in appropriate animal models. Time points for sampling of target tissues should be selected to cover the main time-concentration profiles. 3) Conduct a prospective, randomized, 2-way crossover study to compare plasma NTBI levels in hemodialysis patients treated with generic and RLD (healthy control can be used). Utilize in vitro and in vivo biomarkers such as malondialdehyde, heme-oxygenase-1 (HO-1) RNA or others to evaluate the oxidative stress and toxicity caused by generic and RLD. Statistical analyses will be conducted to determine whether there are any significant differences between generic and RLD in the above tests. This is a 3-year project. Due to the sequential nature of in vivo pharmacokinetic studies, this project is non-severable. Interested small business potential offerors are encouraged to respond to this notice. However, be advised that generic capability statements are not sufficient for effective evaluation of respondents' capacity and capability to deliver the specific equipment as required.
