Spotlight on Compliance: False advertising laws apply in clinical arena
Advertising, incentives must follow rules
By J. Mark Waxman,

One of the challenges in clinical trial operations is to recruit patients to participate. The Food and Drug Administration (FDA) notes that recruitment "methods and material" also should be reviewed as a part of the IRB oversight function.1
Implementing this guidance will require IRBs to review advertising materials, as well as the payment of recruitment fees whether to the investigator, the patient’s primary care physician, or directly to patients.
The FDA points out that direct-to-participant advertising, such as newspaper, radio, and flyers, is not an objectionable practice. Instead, these efforts are perceived as part of the informed consent process, as well as subject selection. In that context, these advertisements would be subject to IRB review, which, in addition to ensuring factual accuracy and consistency with an approved protocol, would consider whether there is a perception created leading to undue influence. The key elements of concern would be any express or implied representation of a favorable outcome from the trial or the ability to receive some other benefit inconsistent with or beyond what is specifically set forth in an approved protocol. [Where only protocol comparison is necessary, expedited review can be appropriate. See 21 CFR§56.110 (b)(2).] An advertising review also would focus on ensuring that:
What can you say?
The FDA suggest the following factually accurate information would be acceptable:
Advertising for subjects is not the same as communications to third parties about trials. For example, an investigators’ brochure is not required to receive IRB approval, although its contents may be useful information for IRB members and staff. Objective and basic information listings of clinical trials being conducted by an institution also would not require IRB approval.
The FDA further has acknowledged that communications not require review. This category includes not only doctor-to-doctor communications, including those soliciting for trial subjects, but also publicity intended for third parties such as investors, which might appear in the trade press or even as advertisements in the financial pages of newspapers.
What can you give?
Payments for participation are recruitment incentives. They may be particularly desirable where benefits are nonexistent (e.g., many trial participants will receive a placebo). The IRB must be informed of such benefits and approve them to ensure they are neither "coercive" or present "undue influence." (21 CFR §50.20.) This means that all information regarding payment should be approved as a part of the approval of the informed consent document. The belief is that material payments may coerce or influence those without means to be to participate in a particular clinical trial. It is generally understood, however, that a payment designed to compensate at a reasonable level for the time commitments required — i.e., as compensation for tests or other participatory activities — can be appropriate. An incentive or bonus for completing the study may also be approved, although the FDA has indicated its view that the entire payment should not be contingent upon completion. This might itself be coercive of an inappropriate continuation in a trial of a participant.
As previously noted, however, where Medicare or Medicaid patients are involved, special concerns exist with respect to participation incentives.
Although the Office of the Inspector General (OIG) has the use of incentives to further clinical trial participation under review, Section 1128A (a)(5) of the Social Security Act ("1128A") pro-hibits the offer or transfer of "remuneration" to a Medicare or Medicaid beneficiary that the person "knows or should know" is likely to influence selection of a provider or supplier of Medicare or Medicaid payable items. A strict interpretation of this provision would mean a cash or noncash gift (in excess of $50 annually per patient) or free goods in connection with a clinical trial where the beneficiary will also receive routine Medicare services may run afoul of the prohibition. And, as the OIG has noted, there is no statutory exception for valuable gifts (e.g., free medications) based upon a beneficiary’s medical condition or its severity.
Recruitment fees to practitioners
Other methods to enhance patient recruitment would be to create financial incentives for the investigators themselves. While varying approaches exist, these incentives could take the form of a per-patient payment or a fixed fee when a minimum or desired enrollment level is met. Either example can create a potential or perceived conflict of interest. As noted by the America Medical Association (AMA), it is unethical to have a conflict of interest arising from payments a researcher might receive which exceed remuneration commensurate with the efforts for the researcher on behalf of the sponsor.3 Therefore, compensation should be at fair-market value and not vary according to the volume of subjects enrolled by the physician receiving the payments. The AMA goes on to note that the nature and source of funding and financial incentives to investigators "must be disclosed . . . as part of the informed consent process."4
The foregoing suggests that an appropriate approach to payments to investigators would be similar to that applied to other areas in which payments are made to physicians for other than direct patient services, most notably the so-called Stark Law and its exceptions. Such approaches focus on documenting both the efforts made and its value. This would include the costs to be incurred for indirect overhead expenses as well as pure time and effort. It also is recommended the amounts involved by established in advance, and records be kept of progress along a budgeted path along the way.
A second variant on payments to obtain trial participants would be a payment to a physician for referring a patient to the trial or the investigator. Payments to another provider to refer study participants are both unethical,5 and likely to violate state (and federal where appropriate) laws prohibiting payments in return for referrals.
