Washington, D.C. 20036 NOTE: THIS DOCUMENT DID NOT COME FROM PPG FILES. Dear Tony: Attached is a copy of my letter to Dr. Schneiderman with regard to the preliminary measures that are necessary before the human trials of the retinoids. Although we cure both quite urgent with regard to the use of prophylactic chemicals in this bad situation, I think we are equally convinced that, to the extent possible, necessary safety measures be sought at the outset. I hope that the National Cancer Institute will provide the necessary resources for this. If not, then I think they ought to abandon research for prophylactic drugs, since similar measures would be necessary for almost anyone of them. Sincerely your, Irving jTVselikoff, M.D. Professor * | BB 0024415 1 Juno 20, 1973 Msrvin nehneidorman, Pli.D.

ConnSdorod against tho reluctance or inability of tun Dof fnu>ii~l,ni'ochc pooplo to mount such studios, tho question immediately arises whether thoy will bo .thought of, otimulntod, supported by others. Tho question is ovou more important at tho outset. If initial studies show promise, tho boudwngon will hardly bo big enough. This, then, suggests -- almost before you stnrt your proto* col -* that nn NCI commitment of nt least modest extent should be known almost at one. Otherwise, j think it would bo wrong for us to consider embarking orv human trials. Among tho things wo discunsod, tho following seemed ira* portnnt from this perspective: 1, Mutagenicity (and carcinogenicity!) of current and future compounds. 2, Body burden and retention in fat and solid orgnn tissurn, Perhaps Uoffman-LaHoch could undertake some of this. 3. Interaction with other drugs. There are a surfeit of capable toxicologists who would be interested in this. 4. rffeet of tho drugs on body enryme systems, using come of tho moro sophisticated tccJmtques now available, 0* Kstahlisluaent of nnirial models for the testing of the drugs in asbestos cancer, Thera are fiovorui lo|>s that could mount such investigation*right off. iJ?B -426-T
