Ten acromegalic patients, four previously untreated, were studied before and at regular intervals during treatment with the long-acting somatostatin analog SMS 201-995 (200-300 micrograms daily for 2 or 3 sc injections for 16-108 weeks). All patients had rapid clinical improvement, with disappearance of excessive perspiration, paresthesias, and headache within the first 6 weeks of therapy. The mean 24-h serum GH concentrations fell from 44.0 +/- 7.8 (+/-SE) micrograms/L before to 5.9 +/- 1.0 microgram/L at the end of therapy. The GH levels from 2-6 h after the acute administration of 50 micrograms SMS 201-995 before the start of therapy correlated significantly with the mean 24-h GH concentrations after 16-108 weeks of treatment (P less than 0.05). The initially increased serum somatomedin-C (Sm-C) levels normalized in 5 of these 10 patients; the mean values were 7.3 +/- 0.9 U/mL before and 2.9 +/- 0.7 U/mL at the end of therapy. The Sm-C and mean GH levels continuously decreased during long term therapy; the concentrations after 1.5-2 yr of therapy were significantly lower than those after 6-12 months of therapy (P less than 0.01 and P less than 0.01, respectively). A slight decrease in the size of the pituitary tumor was noted by computed tomography in three of six patients. Transient clinically detectable steatorrhea occurred in two patients. Postprandial hyperglycemia occurred during therapy in eight patients, while in two patients with type 2 diabetes mellitus carbohydrate tolerance improved in one and deteriorated in the other. SMS 201-995 is a highly effective medical treatment for acromegaly. Clinically improvement occurs rapidly, and the inhibition of serum GH and Sm-C levels persisted even after more than 1 yr of therapy. No important subjective side-effects were noted. SMS 201-995 is an excellent drug in patients in whom acromegaly persists after surgery and for interim treatment to shorten the period of clinical activity after irradiation.

SMS 201-995 was administered to 40 acromegalic patients, in a multicentric study. Some of the results have been analyzed from 37 patients who remained under a long term treatment. Clinical improvement was noted in most patients, especially as concerns soft tissue swelling, sweating, headache. Digestive adverse effects were noted, leading to the drop-out from the protocol (in 4 patients) or in most patients to a slight discomfort related to increasing doses. There was an effect for all the doses used (300, 600, 900, 1500 micrograms in 3 subcutaneous injections per day), compared with pretreatment values, if we consider the mean GH value of each cycle obtained under the different dosages. The highest dose was most effective than the lowest in some cases. However in most patients the 300 micrograms dose was efficient. We could not obtain normalization of GH secretion. However 22/37 patients could reach a good score as concerns the number of GH values less than 5 micrograms/l, during circadian evaluations. In 5/37 patients, the antisecretory effect was insufficient (mean GH above 50% of the pretreatment level). Reduction in tumor volume was highly significant (more than 50%) in 2/11 patients. In conclusion, this study shows the efficacy of SMS 201-995 in improving clinical signs and symptoms of acromegaly, and GH hypersecretion in approximately 80% of the patients. General and metabolic tolerance are rather good. Some points concerning tolerance remain to be investigated.

Long-acting somatostatin analogue (SMS 201-995) inhibits serotonin, bradykinin, prostaglandins, substance P, and vasoactive intestinal peptide, which may be involved in migraine. We therefore decided to test the efficacy of SMS 201-995 in relieving the pain of acute migraine attacks. Headache relief was defined as a reduction in severity from grade 3 or 2 (severe or moderate) to 1 or 0 (mild or none). Patients experiencing migraine attacks were evaluated clinically. A double-blind parallel group trial was performed in which patients randomly received either a subcutaneous injection of placebo (saline) or SMS 201-995 (100 micrograms). SMS 201-995 was significantly more effective than placebo in reducing headache grade at 2 h (1.5 +/- 0.6 vs 2.2 +/- 0.7; p < 0.01), 4 h (1.5 +/- 0.6 vs 2.1 +/- 0.8; p < 0.05) and 6 h (0.8 +/- 0.9 vs 2.1 +/- 0.8; p < 0.001) after the initiation of treatment. By 6 h, apparent headache relief (reduction in severity from grade 3 or 2 to 1 or 0) was experienced in 76.5% of SMS 201-995 treated patients and 25% of the placebo-treated group. Headache relief was significantly better in patients taking SMS 201-995 (p < 0.02). Furthermore, none of the patients became pain-free (headache grade 0) on placebo, while significantly more patients (47%) were pain-free on SMS 201-995 at 6 h (p < 0.01). Headache improvement started significantly earlier in those patients treated with SMS 201-995 than with placebo. SMS 201-995 significantly improves the pain of migraine attacks, 2 h after the beginning of treatment. Additionally, we observed no side effects of SMS 201-995. We therefore conclude that a single dose of 100 micrograms given subcutaneously is an effective and well-tolerated agent for the treatment of migraine attacks.
