396study an adequate number of patients to yield meaningful dataregarding the safety and efficacy of methadone.We have requested 6-month status reports from these programsinstead of the customary annual reports, in order to obtain adequatedata as soon as we possibly can.We expect our recently published regulations to serve as a valuabletool in insuring compliance with existing requirements. In this regard,we have recentl}^ undertaken a program for the inspection of allmethadone maintenance studies. By mid-July, we will have completedinspection of an initial 40 to 50 programs throughout the country,selected on the basis of various criteria.In addition to achieving correction of any deficiencies, we hope tostimulate improved practices and better data collecting procedures.In these inspections, whenever possible, medical officers from ourBureau of Drugs of the Food and Drug Administration will accompau}^district field inspectors. All of this will be done in closecooperation with the Bureau of Narcotics and Dangerous Drugs,which, in addition, has its own program for surveillance of themethadone studies.Preliminary results of these inspections have demonstrated that atleast some programs must be terminated. Action to do so has alreadybeen initiated in some instances.When necessary, a sponsor will be given a time limit to correctdeficiencies or face loss of his investigational status. However, beforea program is terminated, we will contact local health departments,medical societies, and other approved methadone maintenance programsin an effort to insure that continuing treatment for the addictsis available. A letter has also been sent to all State and local drugprogram officials notifying them of our inspection program; I amsubmitting a copy of this letter to you for the record.In addition to review by our own personnel, we have appomted acommittee of outside experts to assist in evaluating data as it accumulates,as well as other aspects of the ongoing programs. The committeewill also be called on to assist in reviewing any new drug applicationsfor methadone maintenance.The members of our advisory committee, some of whom have alreadyappeared before your committee, are Dr. Henry Brill, Dr.Robert Milliman, Dr. William Bloom, Jr., Dr. Max Fink, and Dr.Sidne}^ Cohen. In addition, we have contracted with Daniel X.Freedman, M.D., Dr. E. Leong Way, Ph. D., and Dr. MauriceSeevers to serve as consultants to this particular committee.The concept of narcotic blockade has stimulated a search for otherdrugs, drugs with no addicting potential, with greater safet}^ and oflonger duration than methadone. Acetyl-methadol promises some hopein that its duration of action is 72 hours in contrast to the 24 hoursin which methadone remains effective. Thus, an addict could take hismedication even under supervision, on a twice-weekly basis. However, the possible toxicity of acetyl-methadol needs further stud}'.Cyclazocine is another narcotic antagonist that has been studiedfor the treatment of heroin addiction. Its use has been limited, however,because it has some narcotic actions of its own, it can producerespiratory depression and it may be addicting.

397Naloxone, recently approved for marketing as a narcotic antagonist,has some similarity to cyclazocine but lacks its narcotic actions, andin particular, does not produce repiratory depression. Naloxone hasno reiDorted addictive potential but its short duration of action, 4 to6 hours, limits its usefulness. It has also, like cyclazocine, been testedon a pilot study basis for the treatment of heroin addiction. It ishoped that similar agents having the properties of naloxone, but alonger duration of action, can be synthesized.To reduce the availability of addictive drugs, a variety of agentsare being synthesized and tested to obtain a potent analgesic withno abuse potential. Four such analgesic agents are currently underinvestigation. In addition, the search continues for a safe and effectiveblocking agent in the treatment of heroin and other forms ofaddiction. Only a limited number of drugs have reached the stage ofanimal testing, and a very few have become available for clinicaltests in humans. I can assure you that we at the Food and DrugAdministration are extremely eager to expedite the investigation ofany of these potentially good drugs and are working \\dth variousgroups in order that this can be accomplished.Mr. Chairman, we would be delighted to attempt to answer anyquestions that you or any members of the committee might have.Mr. Perito. Dr. Edwards, you have submitted for the record aletter dated May 14, 1971, subject, "Investigation of MethadoneMamtenance Program"; is that correct?Dr. Edwards. That is correct,Mr. Perito. Mr. Chairman, at this point I would respectfully offerfor the record this two-page memorandum, mth enclosure, submittedby Dr. Edwards.Chairman Pepper. Without objection, it will be received.(SeeExliibit No. 17(b).)Chairman Pepper. You may inquire, Mr. Perito.Mr. Perito. Thank you, Mr. Chairman.Dr. Edwards, to the best of your knowledge, how many addictsare presentl}^ being treated in the United States on methadone?Dr. Edwards. May I ask Dr. Gardner to address liimself to that?He is in charge of our total program.Dr. Gardner. I would estimate that about 20,000 to 30,000 arebeing treated. At the moment v/e have no really accurate figure, butthis is our estimate based on what we know about some of the NIMHprograms and other programs which have submitted progress reportsto us. Our 6-month annual reports which have started to come in -willbe coming in over the next month or so, and should give us a betterfigure. The inspectional programs should also provide a better estimateof the number of addicts under treatment.Mr. Perito. I take it. Dr. Gardner, when you mention the figureof 30,000 addicts you are referring to 30,000 persons presently beingtreated in methadone maintenance programs; is that a correctassumption?Dr. Gardner. That is right.Mr. Perito. Do you have any idea how manj^ addicts are beingtreated throughout the United States on a detoxification basis inaddition to the maintenance basis?60-296—71 —pt. 2-
