The FDA implemented its Drug Efficacy Study Implementation (DESI) program to study and regulate drugs, including stanozolol, that had been introduced prior to the amendment. The DESI program was intended to classify all pre-1962 drugs that were already on the market as effective, ineffective, or needing further study. The FDA enlisted the National Research Council of the National Academy of Sciences to evaluate publications on relevant drugs under the DESI program.
In June 1970 the FDA announced its conclusions on the effectiveness of certain AAS, including stanozolol, based on the NAS/NRC reports made under DESI. The drugs were classified as probably effective as adjunctive therapy in the treatment of senile and postmenopausal osteoporosis but only as an adjunct, and in pituitary dwarfism (with a specific caveat for dwarfism, “until growth hormone is more available”), and as lacking substantial evidence of effectiveness for several other indications. Specifically, the FDA found a lack of efficacy for stanozolol as “an adjunct to promote body tissue-building processes and to reverse tissue-depleting processes in such conditions as malignant diseases and chronic nonmalignant diseases; debility in elderly patients, and other emaciating diseases; gastrointestinal disorders resulting in alterations of normal metabolism; use during pre-operative and postoperative periods in undernourished patients and poor-risk surgical cases due to traumatism; use in infants, children, and adolescents who do not reach an adequate weight; supportive treatment to help restore or maintain a favorable metabolic balance, as in postsurgical, postinfectious, and convalescent patients; of value in pre- operative patients who have lost tissue from a disease process or who have associated symptoms, such as anorexia; retention and utilization of calcium; surgical applications; gastrointestinal disease, malnourished adults, and chronic illness; pediatric nutritional problems; prostatic carcinoma; and endocrine deficiencies.” The FDA gave Sterling six months to stop marketing stanozolol for the indications for which there was no evidence for efficacy, and one year to submit further data for the two indications for which it found probable efficacy.
In August and September 1970, Sterling submitted more data; the data was not sufficient but the FDA allowed the drug to be continued to be marketed, since there was an unmet need for drugs for osteoporosis and pituitary dwarfism, but Sterling was required to submit more data.
