When a testing laboratory is disqualified

What disqualification is for

The purpose section states two objectives, and they point in opposite directions in time.

The first is retrospective: to permit the exclusion from consideration of completed studies conducted by a testing facility that failed to comply with the good laboratory practice regulations, until it can be adequately demonstrated that the noncompliance did not occur during, or did not affect the validity or acceptability of data generated by, a particular study.

The second is prospective: to exclude from consideration all studies completed after the date of disqualification, until the facility can satisfy the Commissioner that it will conduct studies in compliance.

Neither is a licence revocation. A disqualified facility is not shut, barred from operating, or prohibited from running studies. What changes is whether the agency will look at what it produces. The purpose section adds the necessary corollary: a determination that a study may not be considered in support of an application does not relieve the applicant of any other obligation to submit the study's results to the agency. A study that cannot help an application may still have to be filed.

A quieter version of the same lever appears earlier in the part. Where a testing facility refuses to permit inspection, the agency will not consider a nonclinical laboratory study from that facility in support of an application for a research or marketing permit — with the same caveat that the submission obligation survives. Refusing the inspector has the same practical effect as being disqualified, without any proceeding at all.

Three findings, and the third is the one that is hardest to make

The grounds section requires all three of the following to be found before a facility may be disqualified.

First, that the testing facility failed to comply with one or more of the good laboratory practice regulations, or any other regulations regarding such facilities in the chapter.

Second, that the noncompliance adversely affected the validity of the nonclinical laboratory studies. A paperwork failure with no bearing on the data does not, on its own, reach this threshold.

Third, that other lesser regulatory actions — the rule gives warnings or rejection of individual studies as examples — have not been, or will probably not be, adequate to achieve compliance.

That third finding is what makes disqualification a last resort by design rather than by custom. The agency has to conclude not merely that something went wrong and that it mattered, but that the smaller tools available will not fix it. The alternatives section confirms the logic from the other side: the agency may refuse to consider any particular study in support of an application if it finds the study was not conducted in accordance with the regulations, without disqualifying the facility or taking any other action.

Disqualification is also not a substitute for anything else. It is independent of, and neither in lieu of nor a precondition to, other proceedings authorised by the statute. The agency may at any time institute appropriate judicial proceedings, civil or criminal, and any other appropriate regulatory action against a testing facility, against the sponsor of a study submitted to the agency, or both — before, simultaneously with, or after a disqualification. It may also refer the matter to another federal, state or local law enforcement or regulatory agency.

Notice, hearing, and a final order either way

The procedure begins with a written notice. Where the Commissioner has information indicating that grounds exist which in his opinion justify disqualification, he may issue to the testing facility a written notice proposing that the facility be disqualified.

A hearing on the disqualification is conducted in accordance with the requirements for a regulatory hearing set out elsewhere in the chapter. It is a formal proceeding with its own rules, not an informal meeting.

The final order section is symmetrical, and the symmetry is the point. After the hearing, or after the time for requesting one expires without a request, the Commissioner evaluates the administrative record. If he makes the three findings the grounds section requires, he issues a final order disqualifying the facility, including a statement of the basis for that determination, and notifies the facility with a copy of the order.

If he does not make those findings, he issues a final order terminating the disqualification proceeding — also including a statement of the basis for the determination, also with notice and a copy to the facility. A proceeding that fails ends in a written order saying so, rather than simply lapsing.

Both the determination that a facility has been disqualified and the administrative record regarding that determination are disclosable to the public under the agency's public information regulations.

What happens to studies that are already in the file

This is the part that reaches beyond the laboratory, and it is why disqualification matters to anyone reading evidence rather than running a facility.

Once a facility has been disqualified, each application for a research or marketing permit — whether approved or not — containing or relying upon any nonclinical laboratory study conducted by that facility may be examined to determine whether the study was or would be essential to a decision. Where it was essential, the agency also determines whether the study is acceptable notwithstanding the disqualification.

The default in that examination runs against the study. Any study done by a testing facility before or after disqualification may be presumed to be unacceptable, and the person relying on the study may be required to establish that the study was not affected by the circumstances that led to the disqualification — the rule gives submitting validating information as the example.

If the study is then determined to be unacceptable, the data are eliminated from consideration in support of the application. The rule states the further consequence directly: such elimination may serve as new information justifying the termination or withdrawal of approval of the application.

The forward-looking rule is simpler and absolute. No study begun by a facility after the date of its disqualification will be considered in support of any application for a research or marketing permit, unless the facility has been reinstated.

One provision covers the case where a sponsor moves first. Termination of a testing facility by a sponsor is independent of the disqualification machinery. But if a sponsor terminates or suspends a facility from further participation in a study being conducted as part of any application submitted to any centre of the agency, whether approved or not, it must notify that centre in writing within 15 working days, and the notice must include a statement of the reasons.

Who gets told, and how a facility comes back

Publicity is discretionary rather than automatic. On issuing a final order of disqualification, the Commissioner may notify all or any interested persons, at his discretion, whenever he believes disclosure would further the public interest or promote compliance.

The content of such a notice is prescribed. It must include a copy of the final order and must state that the disqualification constitutes a determination that studies performed by the facility will not be considered in support of any application for a research or marketing permit.

Two further clauses govern who receives it and what it means to them. If the notice goes to another federal agency, the agency will recommend that the other agency also consider whether it should accept studies from the facility. If it goes to any other person, it must state that it is given because of the relationship between the testing facility and the person notified, and that the agency is not advising or recommending that the person take any action. A notice is information, not an instruction.

Reinstatement is available and is conditioned on a forward-looking judgment plus a backward-looking one. A disqualified facility may be reinstated if the Commissioner determines, on evaluating the facility's submission, that it can adequately assure it will conduct future studies in compliance, and — where studies are currently being conducted — that the quality and integrity of those studies have not been seriously compromised.

The facility has to make the case in writing, presenting the reasons it believes it should be reinstated together with a detailed description of the corrective actions it has taken or intends to take to assure that the acts or omissions which led to disqualification will not recur. The Commissioner may condition reinstatement on the facility being found in compliance upon an inspection.

When a facility is reinstated, the Commissioner notifies the facility and everyone who was notified of the disqualification. A determination that a facility has been reinstated is itself disclosable to the public.

For a reader assessing preclinical evidence, the useful part of this machinery is what it reveals about how safety data are treated. A regulator that has reason to doubt a laboratory does not argue with individual numbers. It removes the data from consideration and puts the burden on whoever wants to rely on them. That is a stronger response than any published critique of a paper can produce, and it is available only for studies inside the regulatory pipeline in the first place.
