Clinical evaluation of a new hypolipidemic drug, CIBA 13,437-Su

The first clinical trials with a new aryloxy-type of hypolipidemic compound, the tetralin-derivative CIBA 13,437-Su, are reported. Various hyperlipidemic syndromes were treated in a total of 88 patients for periods up to 22 months.

With daily doses of 4–10 mg/kg, i.e. 300-600 mg per day, serum triglycerides and cholesterol were markedly lowered. The most pronounced effect was observed in hyperlipidemias of Types III, IV, and V of the Fredrickson-Lees classification. The pre-β-fraction appeared to be more readily lowered than the β-fraction, although the rather resistant hypercholesterolemia of Type II responded in all cases, yet to a lesser degree, and these patients received the higher doses. Slight transient increases in serum transaminases were observed in 7 out of 88 patients. The compound was very well tolerated subjectively. The results demonstrate that 13,437-Su is a very potent hypolipidemic agent.
