Warning Letter

NOV 22 2006

Dear Dr. Conti;

This letter describes the results of a Food and Drug Administration (FDA) inspection conducted between July 20 and July 24, 2006. FDA investigator Anthony Keller met with you to review your conduct of an experimental procedure to implant placental tissue to treat a variety of illnesses. FDA conducted this inspection under the agency's Bioresearch Monitoring Program, which includes inspections designed to review the conduct of clinical research involving investigational new drugs.

The investigator issued and discussed the Form FDA 483, Inspectional Observations, with you at the end of the inspection.

The inspection revealed that you obtained human [redacted] from a local hospital, carried them to your office, processed the tissue, and implanted it in at least 16 subjects. As a pediatrician you were not otherwise involved with the care of the recipients, who are adults diagnosed with illnesses such as [redacted].

Based on this information, we have determined that your actions have violated the Public Health Service Act (PHS Act) and the Federal Food, Drug, and Cosmetic Act (FD&C Act).

The placental tissue and cells are a biological product as defined in section 351(i) of the PHS Act [42 U.S.C. § 262(i)], in that they are a virus, therapeutic serum, toxin, antitoxin, vaccine, blood, blood component or derivative, allergenic product or analogous product, or arsphenamine or derivative of arsphenamine, applicable to the prevention, treatment, or cure of a disease or condition of human beings. The [redacted] tissue and cells are also a drug within the meaning of section 201(g) of the FD&C Act [21 U.S.C. § 321(g)], in that they are intended for use in the diagnosis, cure, mitigation, treatment, or prevention of disease in man.

In order to introduce or deliver for introduction a biological product into interstate commerce, a valid biologics license (BLA) must be in effect [21 U.S.C. § 355(a); 42 U.S.C. § 262(a)]. A BLA is issued only after a showing of safety, purity and potency for the product's intended use. Before approval, biological products may generally be distributed for clinical use in humans only if the sponsor has an investigational new drug (IND) application in effect [21 U.S.C. § 355(i); Title 21, Code of Federal Regulations (21 CFR) Part 312]. The placental tissue and cells are not the subject of an approved BLA, and you do not have an IND in effect.

The placental tissue and cells you implanted are human cells, tissues, or cellular and tissue-based products (HCT/Ps) as defined in 21 CFR § 1271.3(d). Under 21 CFR Part 1271, HCT/Ps are not subject to license or IND requirements if certain criteria are met. However, these criteria are not met here. An IND application is required for the placental tissue and cell implants because they are intended for non-homologous use (21 CFR § 1271.10(a)(2); 21 CFR 1271.3(c)).

As a result, you violated applicable regulations governing the proper conduct of clinical studies involving investigational new drugs. For example:

Moreover, as explained in 21 CFR § 1271.20, your placentaltissue implants are subject to the requirements of 21 CFR Part 1271, subparts B (Procedures for Registration and Listing), C (Donor Eligibility), and D (Current Good Tissue Practice). Our inspection revealed multiple violations of these requirements. For example:

This letter is not intended to contain an all-inclusive list of deficiencies in your clinical study of this biological product. It is your responsibility to ensure adherence to applicable requirements of the FD&C Act, the PHS Act, and applicable FDA regulations and to protect the rights, safety,and welfare of subjects under your care.

You should notify this office, in writing, within fifteen (15) business days of receipt of this letter of the steps you have taken or will take to correct the noted violations and prevent their recurrence. Your response should include any documentation necessary to show that correction has been achieved. You may submit an IND application to the FDA pursuant to Title 21 CFR Part 312. Information assist you in submitting an IND application is available at Questions regarding submission of an IND application and assistance may be directed to the FDA's Center for Biologics Evaluation and Research Office of Communications, Training, and Manufacturers Assistance at (800) 835-4709. If an IND application is submitted, no clinical investigation is permitted to proceed until the IND application is in effect, as described in 21 CFR §§ 312.20 and 312.40. These regulations are available at

This Warning Letter is issued to you because of the serious nature of the observations noted at the time of the FDA inspection. Please be advised that failure to implement effective corrective actions and/or the commission of further violations may result in the initiation of enforcement action(s) without further notice. These actions could include injunction and initiation of clinical investigator disqualification proceedings, which may render you ineligible to receive investigational drugs.
