10 amenorrhea-patients and 5 galactorrhea-amenorrhea-patients were treated wi2-Br-alpha-ergocryptine (CB 154) as a specific prolactin inhibitor. Side-effects, such as headaches, dizziness, and nausea could be reduced to a minimum by delivering the drug with the meal at night. Before and under the treatment hormone levels were determined in plasma and 24-hour-urine. In the beginning all 15 patients showed a hyperprolactinaemia with a nearly always simultaneously existing hypogonadotropinaemia and the absence of LH-peaks. Also the estrogen- and progesterone-concentrations were on the lower normal level or extremely suppressed. In all patients CB 154 therapy led to a quick decrease of the prolactin levels, to a regaining of typical LH- and FSH-episodes, as well as to a regeneration of ovarian function. 5 women reacted with an ovulation, 3 became pregnant. The galactorrhea diminished significantly and stopped finally after a treatment of one week to 6 months. Discontinuation of CB 154-therapy, however, often provoked the galactorrhea-amenorrhea-syndrome again. For women with normoprolactinaemic amenorrhea a gestagen- and estrogen-test were carried out in order to classify the amenorrhea-type and it was tried to induce an ovulation with Dyneric. For patients with a strong desire for children and without any organic cause for their sterility, in cases of ovarian insufficiency grade I and II a HMG-HCG-treatment was often indicated. In spite of a precise control in order to avoid an overstimulation of the ovaries about 1% of the Dyneric-treated and even 30% of the HMG-HCG-treated patients developed ovarian cysts. In spite of high doses of gonadotropins only 32,5% of our sterility-patients (group I and II) became pregnant, whereas about 60% of the hyperprolactinaemic amenorrhea-patients (group VI) conceived under CB 154 treatment.

The performance of a new low-dose oral contraceptive (Mercilon) containing only 20 micrograms ethinyloestradiol combined with 150 micrograms desogestrel is reviewed. Eight multicentre clinical trials have been completed and provide information on 10,672 women studied over 73,477 cycles. The high efficacy of Mercilon was indicated by the finding that only 10 pregnancies were reported; nine of these occurred in women who omitted to take Mercilon on a number of days and only one in a woman who took all the tablets according to instructions. Cycle control was good; as with all oral contraceptives, the incidence of breakthrough bleeding and spotting was highest in the first treatment cycle and by the sixth treatment cycle the values were usually < 5% and < 7%. More than 80% of women had regular cycles. Side effects were few, the most common being headache, nausea and breast tenderness with incidences in the sixth treatment cycle of less than 2%, 6% and 6%, respectively. There were no significant changes in body weight or blood pressure. Pharmacodynamic investigations showed no adverse effects. Only 1 of 5 studies found an increased response to a glucose tolerance test compared to the pretreatment test. In 8 of 10 studies, serum HDL-C concentrations increased on treatment and this was associated with increases in apoproteins A1 and A2. Serum triglyceride levels also increased but no change occurred in serum cholesterol or LDL-C levels. Haematological factors were assessed in 8 studies and only minor changes were observed. Serum binding protein (SHBG, CBG, caeruloplasmin) concentrations increased and serum androgen levels decreased. Measurements of blood FSH, LH, oestradiol and progesterone indicated adequate inhibition of ovulation. Mercilon is the only oral contraceptive containing 20 micrograms ethinyloestradiol to have high efficacy, to have no adverse pharmacodynamic effects and, importantly, to produce an acceptable bleeding pattern not significantly different from that of oral contraceptives with a higher content of ethinyloestradiol.

The purpose of this study was to compare the biochemical and clinical effects of transdermal estrogen replacement therapy (tERT) in younger and older postmenopausal women. We treated 15 younger (less than 60 y) and 13 older (greater than or equal to 60 y) healthy postmenopausal women (45-72 y) with four successive 8-week regimens of tERT at doses of 0 to 150 micrograms/day, combined with cyclic oral medroxyprogesterone acetate (MPA). In both age groups, there were similar (p = .0001) dose-responsive increases in plasma estrogen levels and decreases in LH and FSH levels, although LH values were lower in older women both before and after tERT (p less than .02). The addition of MPA further suppressed LH and, to a lesser extent, FSH in both younger and older women. The ratio of estrogenized to nonestrogenized vaginal cells increased with tERT (p less than .007) in both age groups, but significant symptomatic improvement of vaginal irritation was noted only at the highest tERT dose. Adverse effects unrelated to age included short-term nausea in 4/28 women, and skin irritation at the patch sites in 20/28 women. Vaginal bleeding was of shorter duration, but breast tenderness was more common in older women. Further studies of long-term tERT effects in elderly women are indicated.

In view of the considerable debate concerning the possible failure of contraception in women taking broad spectrum antibiotics, the authors examined a group of 12 women ages 22-32 in a controlled study. Each had been on longterm therapy with oral contraceptives (OCs) containing ethinyl estradiol (EE) and levonorgestrel (Ng) for at least 6 months and all were in good general health. Blood samples were taken about 11.0 hours after dosing with OCs on days 5, 6, 7, and 8 of their contraceptive cycle, for measurement of EE2, Ng, FSH, and LH by radioimmunoassay. In addition, blood samples were taken on days 19, 20, and 21 of their contraceptive cycle for assay of progesterone concentrations in plasma. The study was repeated in the next cycle of OC use during which the patients took temafloxacin, a broad spectrum quinoline antibiotic in a dose of 600 mg twice daily for 7 days, beginning on day 1 of the cycle. All women completed the study satisfactorily as judged by diary cards, tablet counts, and plasma temafloxacin concentrations. In the early part of the study, some nausea and headaches were experienced; this was due to the taking of the drug on an empty stomach. When the antibiotic was administered with food, this problem was no longer a concern. There was no evidence of any interaction between temafloxacin and OCs. The plasma concentration of EE2 was 61.4 +or- 21.2 pg/ml in the control cycle and 68.5 +or- 26.6 pg/ml in the temafloxacin cycle. The plasma progesterone concentration was 0.53 +or- 0.1 ng/ml in the control cycle and 0.6 +or- 0.24 ng/ml in the temafloxacin cycle (p0.01). No woman demonstrated any significant rise in plasma FSH or LH concentrations during temafloxacin therapy. The authors conclude that there is no evidence for a systematic interaction between temafloxacin and OCs and that there is no need for use of alternative contraceptive methods in women taking OCs who are also being treated with temafloxacin.

Toremifene was given within the dose range of 3-680 mg as a single dose or on five consecutive days to 72 postmenopausal volunteers. Blood samples for clinical chemistry were taken hourly up to 7 h and 1, 2, 3, 7, 10 and 15 days after the last dose of toremifene. The concentrations of serum bilirubin, creatinine, amylase, free thyroxine, cortisol, prolactin, electrolytes and blood glucose remained unchanged at all dose levels. A statistically significant decrease was observed in liver enzymes (ASAT, ALAT, ALP) at the dose levels of 220-680 mg, whereas gamma-GT remained unchanged. A decrease in the concentration of LH and FSH was observed at the dose levels of 46 mg or higher and 220 mg or higher, respectively. These hormonal changes including the increase of SHBG at the dose levels of 220-680 mg and the decrease of antithrombin III (220-680 mg) may be attributed to a weak estrogen-like effect of toremifene. Side effects were minimal: pulse rate, blood pressure and ECG remained unchanged during the test period. Only two patients on 680 mg dose suffered from nausea and vertigo, and one of them discontinued the medication.

Toremifene is a triphenylethylene derivative structurally and pharmacologically similar to tamoxifen. This Phase I trial assessed the safety, pharmacokinetics, anti-estrogenic, and estrogenic effects of toremifene at six dose levels (10, 20, 40, 60, 200, and 400 mg/day). The most common side-effects associated with therapy included gastrointestinal (nausea/vomiting 43%), anti-estrogenic (hot flashes 29%), and CNS (dizziness/vertigo 12%). Three patients with bone metastases from breast cancer developed hypercalcemia. At doses greater than or equal to 40 mg/day a decline in LH and FSH occurred which was not statistically significant. At all doses tested SHBG rose during therapy. A dose dependent estrogenic blockade was seen on the vaginal epithelium following challenge with transdermal estradiol. Steady-state concentrations of toremifene were reached within 4 weeks, and at doses greater than or equal to 60 mg/day ranged from 879-3445 ng/ml. The half-life was found to be 5 days, and at three weeks following discontinuation of treatment concentrations greater than 24 ng/ml were detected. The N-desmethyl and 4-hydroxy metabolites achieved steady state levels within 4 weeks and had half-lives of 6 and 5 days respectively. Partial responses were seen in 4 patients, 3 with breast cancer treated at 200 mg/day and 1 with endometrial cancer treated at 400 mg/day.

The effects of ketoconazole, a synthetic imidazole derivate, were evaluated in 42 women affected by acne (17 cases) and/or hirsutism (36 cases) treated with 400 mg/day for 3-6 months. Androstenedione, total and free testosterone, 5 alpha dihydrotestosterone and dehydroepiandrosterone levels progressively dropped during treatment while 17 alpha hydroxyprogesterone, estradiol, ACTH, cortisol, LH and FSH levels increased. Dehydroepiandrosterone sulfate decreased only towards the end of treatment, while estrone, sex hormone binding globulin, and PRL remained unchanged. Daily mean +/- SD rate of hair growth, measured by a special image analysis processor, decreased within 3 months of therapy from 0.258 +/- 0.058 to 0.184 +/- 0.039 mm/day (P less than 0.02) and mean +/- SD hair diameter from 0.123 +/- 0.015 to 0.110 +/- 0.013 mm (P less than 0.05) together with decreasing hormone levels. The therapeutic effects of ketoconazole on hirsutism was evident at 6 months in only 14 subjects, while no significant change in hirsutism score was recorded in 22 women who failed to complete the therapy. Acne improved in all cases. Several side effects and complications arose during treatment, such as headache, nausea, loss of scalp hair, hepatitis, and biochemical changes. Even though ketoconazole improves hyperandrogenism, only selected patients are eligible for treatment as scrupulous monitoring is required.

We performed phase I study of FK 435, a new antiestrogen, in 30 patients with advanced breast cancer. Slight to moderate adverse reactions were noted as follows. Single-dose study: anorexia, nausea, lassitude in one patient (80 mg), decreased serum calcium in one (160 mg), redness, tenderness in one, facial flushing, hot flushes, headache in one (320 mg). Repeated-dose study: anorexia, nausea in one patient (40 mg/day), anorexia, diarrhea, increased FSH in one, increased PRL in one (80 mg/day). FK 435 was well tolerated. Tmax was 3-5 hours, T1/2 about 25 hours. Most of FK 435 was excreted into urine as glucuronide.

In this pilot clinical trial conducted in 10 postmenopausal women with advanced breast cancer, we evaluated the endocrine effects and toxicity of combined somatostatin analog and dopaminergic therapy in the attempt to suppress both growth hormone (GH) and prolactin (PRL) secretion. The patients' mean age was 63 years (range: 54-77) and the average number of previous treatments was 4.8 +/- 2 (SD). All patients were treated with the somatostatin analog SMS 201-995 (100-200 micrograms s.c. in a.m. and h.s.) and bromocriptine (2.5 mg orally twice a day). During treatment, GH levels following provocative testing (either L-DOPA or insulin-induced hypoglycemia) were suppressed in 7/9 patients. Basal somatomedin-S (Sm-C) levels declined in 6/9 women. Both GH and Sm-C levels decreased in 4 patients, while in the remaining 5 only one of the two parameters was lowered on treatment. PRL secretion (during provocative TRH testing) was almost totally abolished in 8/9 patients. The treatment did not affect circulating levels of FSH, LH, E1, E2, E1-S, T4, T3RU, or cortisol. Seven patients experienced no side effects. Nausea occurred in 3, but was severe enough in only one to require discontinuation of therapy. One patient experienced disease stabilization consisting of less than 50% regression of skin nodules and pleural effusion, a decline in CEA titer, and an improved performance status lasting 7 months. We conclude that combined SMS 201-995 and bromocriptine therapy is safe and frequently suppresses GH and PRL secretion. Its role in the treatment of metastatic breast cancer should be tested in patients with less advanced disease.

A phase II study with cyproterone acetate (CPA) was done as the primary treatment in female breast cancer patients. Twenty-three patients, mean age 64 years, range 52-75 years, were entered and treated with CPA 400 mg daily. Twenty patients were evaluable and responses were sparse. There was one partial and one complete remission, 17 patients were stable and one patient progressed within 3 months. Side-effects were frequent: five patients complained of nausea, three had severe weight loss, one suffered from depression and seven showed disturbed liver function tests. Six patients had to stop treatment for side-effects, while two other patients were taken off treatment because they developed an acute necrotizing hepatitis. The hepatitis recovered after drug withdrawal in both patients. The serum levels of CPA, cortisol, androstenedione, DHAS, LH, FSH and prolactin were measured during CPA treatment. The levels of cortisol and androstenedione did not change, while LH, FSH and DHAS were suppressed. The DHAS showed an inverse relation to serum CPA concentrations. The prolactin levels rose uniformly. The therapeutic effect of CPA in postmenopausal patients with advanced breast cancer is disappointing, and inferior to that of other progestins. Side-effects are frequent, possibly as a result of the high dosage used in this study. The hormonal changes are different from those of other progestins, which may explain the different efficacies.
