Hydrazine sulfate and cachexia.
Hydrazine sulfate trials involving cancer patients were performed in Russia (then the Soviet Union) and by researchers at Harbor-UCLA Medical Center during the 1970s and 1980s. A 1979 Soviet study with 225 patients reported a 65% anti-cachexia response (improved appetite, less/no weakness, less/no pain, and movement toward normal laboratory findings) and 44% antitumor response (either reduction of tumor volume or three to six months of tumor stabilization). Harbor-UCLA researchers performed a trial, involving 38 patients with advanced cancer and weight loss, in 1984. They found that "the rate of total glucose production was significantly decreased after 30 days of hydrazine sulfate compared to placebo treatment (2.46 mg/kg/min versus 3.07 mg/kg/min, respectively; p<0.05)."
Another double-blind, placebo-controlled study performed by Harbor-UCLA researchers involved people with advanced, unresectable non small cell lung cancer (NSCLC) who had had no prior chemotherapy. All 65 patients received the same chemotherapy and dietary counseling, but some got 60 mg of oral hydrazine sulfate, three times/day, and the rest took a placebo. The HS group showed "significantly greater caloric intake and albumin maintenance (p<0.05)." The HS group also had a longer median, but not statistically significant, survival time (292 v 187 days). Instead of gaining the interest of conventional oncology, this Harbor-UCLA study, published in the journal of Clinical Oncology in 1990, was denigrated by an accompanying editorial. Dr. Steven Piantadosi, a member of FDA's Oncology Drug Advisory Committee at the time and physician at Johns Hopkins Oncology Center, criticized the study for being "too small." The same journal issue contained eight trials with fewer patients than the Harbor-UCLA study. Only the hydrazine sulfate study was criticized.
Three multicentric phase III studies, conducted by the National Cancer Institute (NCI) and published in 1994, virtually buried HS as a treatment for cachexia. The NCI studies said that hydrazine sulfate had no benefit. However, investigation by the US General Accounting Office forced the NCI to admit that 94% of all patients involved in the studies were taking tranquilizers, barbiturates, or alcohol, which are incompatible with hydrazine sulfate. HS is a monoamine oxidase (MAO) inhibitor. "The use of tranquilizers, barbiturates, and/or alcoholic beverages with hydrazine sulfate destroys the efficacy of this drug," says Dr. Gold, "and represents a clear clinical hazard [e.g., severe hypertension]." The NCI studies, given so much clout in the US, were designed to fail.
Even though NCI and the FDA have refused to accept hydrazine sulfate as an anti-cachexia therapy, Russia and other countries--particularly in Europe--permit its use. It is also legal in Canada. Hydrazine sulfate is sold as Sehydrin[R] by the Russian manufacturer Pharmsynthez.
