Description
Points to Consider documents provide a flexible approach in which FDA provides and updates its guidance on regulatory issues in many areas of drug development. Such documents are particularly useful in the rapidly evolving field of biotechnology-derived drugs and other biologics. The Center for Biologics Evaluation and Research (CBER) set out to revise the "Points to Consider (PTC) in the Manufacture and Testing of Monoclonal Antibody Products for Human Use" with several objectives. An important goal was to facilitate initial development of monoclonal antibodies for serious or life threatening indications. Additionally, it was felt that some of the information in the 1994 document required updating and streamlining. Finally, it was necessary to review this document for consistency with current CBER policy and with International Conference on Harmonisation (ICH) documents dealing with this category of products. This updated document supersedes the 1994 version, and is designed to assist sponsors and investigators regarding monoclonal antibody (mAb) product development, including information to submit when filing Investigational New Drug Applications ("INDs") and License Applications. Although this document does not create or confer any rights for or on any person and does not operate to bind FDA or the public, it does represent the agency’s current thinking on monoclonal antibody products for human use.
Scope & Applicability
Product Classes
10Testing recommendations for antibodies with product contact
expected radiation dose to a target organ
structure of the antibody (e.g., whole mAb, Fab fragment)
Initial studies of radioimmunotherapeutic mAb should employ escalating single-doses
Such models can provide information on specific targeting of desired cells, especially with radiolabeled mAb.
tested to confirm contaminant removal
CHO cell lines express defective retrovirus particles.
Retrovirus testing is not required for murine hybridomas.
Specific issues to be addressed for Ab2 vaccines
Monoclonal antibodies conjugated with toxins, drugs, or radionuclides.; In the case of immunoconjugates of any type, intact conjugate should be distinguished from free mAb.
Stakeholders
4Responsible for declaring acceptable market names on labels.
Possible to conduct the FIH trial in healthy volunteers
Assist sponsors in the nonclinical evaluation
Entity responsible for submitting applications under section 524B
Regulatory Context
Attributes
10Dosimetry estimates for radiolabeled antibodies.
Calculations considering specific organs like liver, spleen, and kidney
patients should have a Karnofsky score greater than 70
Information recommended for inclusion in the notification
mathematical equations used to derive the estimates
mathematical equations used to derive the estimates
antigen mass is likely to alter the bioavailability of the mAb
Cmax may be more informative for safety
time to reach peak exposure
AUC or Cmin may correlate with efficacy
Identified Hazards
Hazards
7steps taken to prevent or control contamination by... transmissible spongiform encephalopaties (TSE) agents
Viruses such as Ectromelia, Hantaan virus, and LCM virus tested in Appendix II
potential toxicity should be described based on radiation exposure
Risks arising from unverified design changes late in the cycle
Cells from patients who are known to have developed Creutzfeld-Jakob disease (CJD) should not be used.
Retrovirus testing of cell lines: Retrovirus contamination of cells from different species varies.
Screening for adventitious viruses (other than retroviruses) should include routine in vivo and in vitro tests
