The year 2002 marked the 100th anniversary of the 1902 Biologics Control Act which gave the Food and Drug Administration's Center for Biologics Evaluation and Research (CBER) the authority to regulate biological products and ensure the safety of the American public. |
Noncompliance With FDA |
A Notice of Intent to Revoke letter was issued
on April 17, 2002, to Allergy Laboratories of Ohio,
Inc., Columbus, Ohio. The firm manufactures standardized
and non-standardized glycerinated and aqueous allergenic
extracts for the diagnosis, prevention, or treatment
of allergies. Allergy Laboratories of Ohio, Inc.,
continued to operate in significant noncompliance
with the applicable standards and regulations,
and management did not implement adequate corrective
actions for items noted in the 2000 and 2001 inspections.
The firm’s license was revoked effective
June 6, 2002.
On March 21, 2002, Bayer Corporation announced the discovery of apparent product tampering for Gamimune® N, Immune Globulin Intravenous (Human), 10%, Solvent/Detergent Treated (IGIV). IGIV is approved by FDA for use in the treatment of Primary Immune Deficiency, Kawasaki’s disease, Chronic Lymphocytic Leukemia, bone marrow transplantation, Pediatric AIDS, and Immune thrombocytopenic Purpura. Bayer received customer reports describing the presence of a white precipitate in the solution in vials of IGIV. Bayer initiated a voluntary recall of two lots of IGIV relating to these vials - lot 648X078, recalled February 1, 2002, and lot 648X062, recalled March 14, 2002. Bayer received no reports of adverse reactions. Bayer also advised health care professionals, distributors, pharmacists, or patients in possession of vials from these lots not to use them and to report them to Bayer Clinical Communications.
In Fiscal Year (FY) 2002, regulatory scientists
in CBER’s Bioresearch Monitoring Branch,
part of the Division of Inspections and Surveillance/Office
of Compliance and Biologics Quality, prepared and
issued 16 Warning Letters (as compared to 11 in
FY 2001) for deviations from regulations (21 CFR
Parts 50, 56, and 312) designed to protect the
safety, rights and welfare of human subjects participating
in research and to assure the validity of data
submitted to CBER in support of licensing applications
or supplements. All of these Warning Letters may
be found in redacted form (i.e., trade secret,
confidential commercial or privacy related information
which can not legally be disclosed is removed)
on the FDA website at http://www.fda.gov/cber/efoi/warning.htm.
On rare occasions, careful evaluation of the evidence concerning the conduct of a clinical trial shows that the clinical investigator appears to have repeatedly or deliberately violated regulations governing the conduct of clinical studies involving investigational biologicals. In such situations, CBER sends the clinical investigator a written notice detailing the alleged violations of good clinical practice regulations (primarily 21 CFR Parts 50 and 312) and initiates an administrative proceeding to determine if the clinical investigator should be disqualified from receiving, in the future, any investigational products regulated by FDA. After the clinical investigator has an opportunity to respond to the allegations, CBER evaluates all of the available evidence and may prepare a Notice of Opportunity for Hearing (NOOH) letter to be issued to the clinical investigator.
The NOOH letter informs the clinical investigator of his/her right to a regulatory hearing under 21 CFR 16.22 and 312.70(a), the next step in the process of determining whether or not he/she should be disqualified. No final FDA decision has been made at the time of issuance of the NOOH letter regarding eligibility to continue to receive investigational products. The following persons conducted clinical investigations regulated by CBER and received NOOH letters in FY 2002:
These NOOH letters are available in redacted form on the FDA website at http://www.fda.gov/foi/nooh.
The action was in response to an inspection of the firm by the Florida District Office that found numerous significant deficiencies from the applicable regulations and standards. Deficiencies included the failure to collect blood by aseptic methods and inadequate donor suitability determinations.
In addition, deviations were noted in the firm's
records, and training. In addition, Quality Assurance
oversight was also found to be insufficient. The
firm's initial response to the action was not acceptable,
and the firm continued to operate within the State
of Florida. As a result of FDA's inspectional findings,
on July 23, 2002, the Florida State Department
of Health negotiated
a cease and desist agreement with the firm that
required the firm to bring operations into compliance
with FDA requirements before intrastate blood product
distribution could resume. The firm subsequently
provided an acceptable corrective action plan to
FDA, and Florida District Office performed an inspection
of the facility and verified that the corrective
actions had been implemented. Therefore, on September
16, 2002, CBER notified the firm that its U.S.
license had been reinstated.
Deviations from CGMPs for Blood and Blood Components Results in Warning Letter |
On February 21, 2002, the FDA’s San Juan
District Office issued a Warning Letter to Las
Americas Laboratory and Blood Bank, Inc., Hato
Rey, Puerto Rico. The firm is a private licensed
hospital blood bank. An FDA inspection conducted
from December 4 - 12, 2001, revealed deviations
from the Current Good Manufacturing Practices (CGMPs)
for Blood and Blood Components, and Additional
Standards for Human Blood and Blood Products. The
deficiencies cited in the letter included the following:
failure to store and handle platelets under appropriate
temperature conditions; failure to promptly notify
the Center for Biologics Evaluation and Research
of errors; failure to have a system to record,
document and investigate discrepancies related
to the quality of blood products; failure to follow
appropriate donor screening procedures; and failure
to maintain adequate records of the processing
and distribution of blood.
FDA Inspections Find ARC in Significant Non-Compliance with 1993 Consent Decree |
On December 13, 2001, FDA asked a Federal Court to hold the American National Red Cross (ARC) in contempt of a 1993 consent decree covering ARC's blood program. FDA also asked the court for authority to levy prospective fines against ARC for future violations. ARC supplies approximately 45 percent of the Nation’s blood supply. FDA’s actions followed inspections of ARC facilities over the last 16 years that have shown continuing ARC violations.
These inspections include one from February through April 2000, of ARC's national headquarters, which provides quality assurance oversight for all of ARC’s regional and laboratory facilities, and an inspection of ARC's Salt Lake City facility from March through May, 2001. Despite ARC’s agreement to make substantial improvements, as promised in a consent decree signed in May 1993, these inspections revealed persistent and serious violations of blood safety rules.
“FDA is acting today to ensure that the American Red Cross takes much more seriously its role as guardian of the safety of the Nation’s blood supply, which is essential to the public health,” said Bernard A. Schwetz, D.V.M., Ph.D., FDA's Acting Principal Deputy Commissioner. “Unfortunately to date ARC has exhibited a corporate culture that has been willing to tolerate an unacceptably low level of quality assurance and a lack of concern for the public it is supposed to serve. In our view, these prospective penalties are necessary to ensure that ARC is held financially accountable for each unit of blood it fails to manage properly.”
FDA laws and regulations establish overlapping safeguards designed to protect the blood supply. Because there is always some degree of risk, however small, in receiving blood products, each individual safeguard is considered critical to minimizing that risk.
Although the failure of an individual safeguard, such as improper record keeping, does not automatically translate into the release of unsafe products, it may increase the potential risk. ARC’s violations of the consent decree and blood safety regulations have decreased the margin of safety.
The need for strengthening ARC's motivation for compliance was particularly evident from the findings of FDA's sixth and most recent inspection of ARC's national headquarters in February-April 2000. This inspection revealed violative conduct, including the following:
An FDA inspection during March - May 2001, of the Salt Lake City facility further demonstrated that ARC had not corrected these violations. Numerous violations were observed relating to quality assurance and ARC's continuing failure to monitor and exercise effective control over its regions. For example, possibly unsuitable donors were not deferred appropriately and quality assurance personnel did not investigate these deviations or attempt to correct them.
Dr. Schwetz emphasized that, as FDA works to improve blood safety, patients requiring blood transfusions should not hesitate to receive blood. “The risk of not receiving a needed transfusion far outweighs the risk of receiving blood,” he said. “I also want to encourage Americans to continue to donate blood. Giving blood is a safe and unselfish act. The health of millions depends on it,” he added.
FDA's legal action consisted of a motion asking a federal court to issue an order requiring ARC to show cause why it should not be held in contempt of a 1993 consent decree and to impose on ARC prospective fines to encourage future compliance. The motion and supporting documents were filed in the United States District Court for the District of Columbia.

Test Kit for Syphilis Could Provide False Negative Results |
On July 22, 2002, Trinity Biotech, IDA Business Park, Bray, Co., Wicklow Ireland, recalled the CAPTIA Syphilis G Elisa Test Kit, Lot numbers K00841, K00842, K00838, and K00839. The product is a diagnostic test used to detect syphilis in the blood and to screen blood and/or plasma donors by blood banks to rule out a history of syphilis. The reason for the recall was as follows: blood and/or plasma samples tested with the affected lots could provide a false negative result. In other words, blood and/or plasma samples with a history of syphilis could return a result of no history for syphilis.
The potentially false negatives were due to a shift in the performance of the Low Titre Positive Control in the lots mentioned above. This shift in performance can cause blood/plasma samples to result in low positive readings equivalent to negatives. The product was distributed in California, Florida, Minnesota, New Jersey, and Pennsylvania between May 16, 2002, and May 31, 2002. FDA considers there to be a high risk of adverse health consequences from continued use of the above name lots. Blood and/or samples tested on these lots should be retested.
Regulation of Human TissueThe Center for Biologics Evaluation and Research (CBER) currently regulates,
under 21 CFR Part 1270 and 1271, human tissue intended for transplantation
that is recovered, processed, stored, or distributed by methods that do not
change tissue function or characteristics and that are not currently regulated
as a human drug, biological product, or medical device. Examples of such tissues
are bone, skin, corneas, ligaments and tendons. Part 1270 requires tissue establishments
to screen and test donors, to prepare and follow written procedures for the
prevention of the spread of communicable disease, and to maintain records.
21 CFR Part 1271 requires the phased-in registration of tissue establishments. |
On June 17, 2002, FDA’s Atlanta District Office issued a Warning Letter to the president and CEO of CryoLife, Inc., Kennesaw, Georgia. The Atlanta District Office conducted an inspection of the firm from March 25 - April 12, 2002. The investigation determined that the firm manufactures and distributes cryopreserved heart valves. FDA investigators documented significant deviations from the Quality System Regulations, 21 CFR Part 820.
The Warning Letter detailed the following deviations: failure to fully validate and approve a process whose results cannot be fully verified by subsequent inspection and test; failure to use sampling plans, which are based on a documented valid statistical rationale; failure to revalidate a process conducted in response to changes or process deviations; failure to adequately inspect or test incoming product to verify conformance of incoming product to specifications; failure to fully document process validation activities and results; and failure to fully monitor and control the component and device characteristics during production.
Contaminated Human Tissue Results in Recall |
On August 14, 2002, FDA issued a Press Release announcing that the agency had ordered Cryolife, Inc., of Kennesaw, Georgia, a human tissue-processing firm, to recall distributed human tissue processed between October 3, 2001, and August 14, 2002. Under the order, the firm must also withhold from the market or destroy tissue processed after that date. FDA took this action because the agency determined that Cryolife could not ensure that the human tissue it processed for transplantation was free from fungal and bacterial contaminants.
Donor tissue that had been processed by Cryolife on or after October 3, 2001, was associated with the November 2001 death of a patient who received a soft tissue implant during reconstructive knee surgery.
“This order not only protects patients from the unacceptable level of risk associated with tissue processed by Cryolife, it sends a clear signal that FDA stands ready to take whatever action is necessary to ensure the safety of human tissue,” said Dr. Lester M. Crawford, FDA Deputy Commissioner.
During an inspection of Cryolife from March 25 through April 12, 2002, FDA found numerous significant violations of FDA regulations. FDA issued a Warning Letter to Cryolife on June 17, 2002, after determining, among other things, that the firm had neither adequately investigated its validation of processing and testing methods, nor implemented recommendations from the Centers for Disease Control and Prevention (CDC), or any other procedures to ensure that tissue processed by the firm was not contaminated.
Current federal regulations for human tissue require firms to prepare, validate, and follow written procedures to prevent infectious disease contamination or cross-contamination during tissue processing. Contamination may be caused by a variety of infectious disease agents, including viruses, bacteria, fungi, and transmissible spongiform encephalopathy (TSE)-associated prions.
After determining that Cryolife had failed to take adequate corrective measures to address possible infectious disease contamination of tissue in inventory and distribution, and after reviewing information provided by the firm in response to FDA’s warnings, FDA issued the present order.
FDA’s concerns described in the order related specifically to bacterial and fungal contamination of soft tissues such as cartilage and tendons. FDA’s investigation revealed, among other things, that, of those standard operating procedures implemented by Cryolife to prevent infectious disease contamination or cross-contamination, many were not followed. In addition, Cryolife improperly distributed tissue from a donor after the firm confirmed the presence of harmful microorganisms in tissue samples from the same donor.
The FDA Press Release stated that, “If a bacterial or fungal infection were to occur following a tissue transplant, the signs and symptoms would usually appear within days to weeks after transplantation. Therefore, it is unlikely that patients who have not recently received a transplant are likely to be at future risk. However, concerned patients are encouraged to contact their physicians.”
On August 21, 2002, FDA issued a Public Health Notification to Health Care Providers regarding Cryolife heart valves:
“Allograft heart valves processed and supplied
by Cryolife have not been included in the FDA recall
order. This is because these devices are essential
for the correction of congenital cardiac lesions
in neonate and pediatric patients and no satisfactory
alternative device exists. Under these circumstances,
the benefit of these devices outweighs the risk
associated with the current manufacturing deficiencies.” |
Vaccine Recalled Due to Subpotency |
In April 2002, Merck & Co., Inc, West Point, Pennsylvania, recalled Hepatitis A Vaccine, Inactivated (VAQTA) (packaged in single dose pre-filled syringes) Pediatric/adolescent formulation: 25 U / 0.5 mL single dose syringe - Adult formulation: 50 U /1 mL single dose syringe.
The reason for the recall was that some syringes
may have antigen levels below the minimum product
specification limit. As a result, a possibility
exists that persons vaccinated with the indicated
lots may have been insufficiently protected against
Hepatitis A. The lots were distributed in the international
market and have been recalled specific to the international
governing regulations and in accordance with local
regulatory authorities in these countries.
