Compliance Requirements for Stem Cell Trials

BayBiotech.NET

Stem Cell Therapy although holds promises for the treatment of many diseases, this is an area not much explored yet and many countries worldwide are drafting the guidelines for conducting safer clinical trials. Therefore, it is accepted widely that prior to conducting clinical trials with stem cells a stronger than usual proof of concept may be required for the safety and efficacy of the therapy.

One of the major concerns is the rapid cell division cycles of such cells that may lead to tumor generation. Thus, it is recommended that the dose of administered cells to humans must be well adjusted to below the minimum number of cells observed to form tumors in animal models.
Due to many unanswered questions regarding the safe use of stem cells a long-term follow-ups and Biovigilance must be planned carefully before starting a trial.

In October, 2009,Center for Biologics Evaluation and Research (CBER), FDA, has issued a draft guidance to potential sponsors (cord blood banks, or registries, and individual physicians serving as sponsor-investigators) to assist in the submission of an investigational new drug application (IND) for certain unlicensed (not in accordance with 21CFR 601) hematopoietic progenitor cells, cord (HPC-C), that are needed for treatment of a patient with a serious or life-threatening disease or condition and there is no satisfactory alternative treatment.

The draft guidance is available at the following link: http://www.fda.gov/downloads/BiologicsBloodVaccines/GuidanceComplianceRegulatoryInformation/Guidances/Blood/UCM187146.pdf

Sponsors are encouraged to send in IND and BLA (Biological License Applications) as soon as possible to allow sufficient time for review, comment, and resubmission as needed to complete all actions by the end of this 2 yr period.

Since the cell/ gene therapies are emerging prime areas, a worldwide effort is ongoing for prospective harmonization and convergence of regulatory approaches. Several countries within European Commission as well as other part of the world are working closely via exchange of guidelines to evolve successful strategies for acceptance and harmonization of such therapies.

A world wide map on stem cell guidelines is available at: http://www.mbbnet.umn.edu/scmap.html.

Amendments for High Risk Device Type Regulatory Pathway

BayBiotech.NET Government Accounting Office (“GAO”) has issued a long-awaited report evaluating the use of the 510(k) process by the Food and Drug Administration (“FDA” or the “Agency”) in the January of 2009. Report mainly focused on Preamendment class III devices. Although most high-risk class III medical devices are subject to the demanding premarket approval (“PMA”) process, preamendment class III devices may be cleared through the 510(k) pathway until FDA issues regulations requiring a PMA. Under the Safe Medical Devices Act of 1990, FDA was required either to reclassify preamendment class III devices into class I or II, or (2) issue regulations requiring PMA approval for the devices, GAO noted that 20 preamendment class III device types have not yet been addressed by the Agency. GAO has urged FDA to take required steps to address the remaining class III devices that continue to be eligible for 510(k) review. As a result of the report, FDA has committed to address al...

Harmonization by Doing (HBD): Japan & U.S. Collaboration

BayBiotech.NET HBD is an international cooperative effort by Japan and US for regulatory convergence for Medical Devices. The efforts are focused on to develop global clinical trials and address regulatory barriers for timely device approvals. To address the needs for additional evaluation, the HBD initiative is a pilot project launched jointly by FDA and MHLW-PMDA for the premarket review of device cardiovascular technology. Instead of taking a theoretical approach to harmonization, HBD is focused on Proof of concept by utilizing parallel development, application submissions and review of actual medical device projects. HBD Study intends to collect and analyze regulatory submission data from multiple applications in the U.S. and Japan. The purpose of the study is to further understand differences that may exist with format and content, to define best practices and to improve globally harmonized processes.

510(k) Summary or Statement

BayBiotech.NET A premarket notification from a manufacturer must include either a summary of the 510(k) safety and effectiveness information of the product upon which the substantial-equivalence determination is based or a statement that this information will be made available by the 510(k) applicant to any person within 30 days of a written request. As per FDA definition, these are the definition of Summary and Statements: Summaries are released by FDA regarding a 510(k) clearance when requested under the Freedom of Information (FOI) Act whereas Statements are used to arrange for this FOI request to be fulfilled by the 510(k) applicant. 510(k) Summaries: If a summary is included, it must be submitted with the 510(k) notification as per FDA guidelines. The summary must be complete and correct in order for FDA to complete its review of a 510(k) submission. FDA will accept summaries and amendments until it issues a determination of substantial equivalence. If a summary has be...
