A phase I study of NK 622 (toremifene citrate), a novel antiestrogen, was conducted in female patients with cancer. Patients received a single oral dosing or daily once oral dosing for five consecutive days. Any adverse effects were not experienced in the single dosing of 40 or 60 mg of NK 622. In the daily administration of 10, 20, 40, 60, 120, 240 and 480 mg/day, one of three patients who received 20 mg/day experienced grade 1 anorexia, three of four patients received 240 mg/day experienced adverse effects: Grade 1 leukopenia in one patient, Grade 1 general hot flush in one patient, and Grade 1 nausea, hot flush in the face and vertigo, Grade 2 anorexia, fatigue, dull headache and general hot flush in another one patient. These symptoms recovered to normal levels after treatment. Serum hormone levels were examined in postmenopausal patients, and a significant increase of the sex hormone binding globulin level was observed in the patients received 120 and 240 mg/day doses. Serum levels of NK 622 determined as free base (TOR) reached the peak levels in 2 to 4 hours after administration on the 1st and 5th day in daily treatment, while a metabolite N-demethyltoremifene (TOR-1) reached the peak level in 4 to 170 hours. Maximum serum levels and area under the concentration versus time curves of TOR and TOR-1 increased dose-dependently. These values also increased by repetition of the treatment. Half-lives of TOR and TOR-1 in serum ranged in 74.5 to 148.9 hours and 154.1 to 653.1 hours, respectively. From these results, it was concluded that safety and efficacy of NK 622 should be assessed by using 240 mg or less doses in clinical phase II studies where breast cancer patients received long term treatment with NK 622.

A comparison of the triphasic Triphasil and the combined oral contraceptive Diane 50 for treatment of acne for 6 cycles showed significant improvement in both groups. Triphasil (Wyeth-Ayerst) contains 50 mcg levonorgestrel and 30 mcg ethinyl estradiol, 75 mcg levonorgestrel and 40 mcg ethinyl estradiol for 5 days and 125 mcg levonorgestrel and 30 mcg ethinyl estradiol for 10 days. Diane 50 (Schering Ag) contains 2 mg cyproterone acetate and 50 mcg ethinyl estradiol for 21 days per cycle. 10 women in each group had physical, pelvic, ophthalmologic and neurologic exams, hematologic and biochemical screens, assays of free testosterone, sex hormone binding globulin (SHBG), androstenedione, dehydroepiandrosterone SO4 (DHEAS), progesterone, and computations of acne and hirsutism scores. Subjects had used tetracyclines, isotretinoin, erythromycin, topical clindamycin and benzoyl peroxide previously, but were withdrawn from medication in the cycle before the intervention. The mean acne scores, derived from grading and counting lesions and comedones, fell from 63.3 to 6 in the Diane 50 and from 64.2 to 4.5 in the Triphasil group. Subjective results were excellent for 6, good for 2 and unsatisfactory for 2 in the Diane 50 group, and excellent for 8 and good for 2 in the Triphasil group. In both groups mean free testosterone, androgen index, androstenedione and DHEAS, and an increase in SHBG were documented. 5 Triphasil and 5 Diane 50 subjects had increased cholesterol levels during the trial, the only abnormality detected. Side effects reported were recurrence of varicose veins and hemorrhoids in 1 women who withdrew, and complaints of mastalgia, nausea, dysmenorrhea, migraine, headache, backache and vaginal discharge.

The aromatase inhibitor, 'pyridoglutethimide' (PyG), has been shown previously to suppress serum oestrogen levels in postmenopausal breast cancer patients and to achieve clinical responses at a dose of 500 mg twice daily (b.d.). This report gives the results of a detailed pharmacokinetic and endocrine study of PyG in ten patients. Four doses were tested at intervals of 2 weeks in the following order: 200 mg b.d., 400 mg b.d., 800 mg b.d., 1200 mg b.d. Concentration-time profiles of serum levels of PyG were curvilinear in all patients probably reflecting a saturation of metabolic enzymes. During repeat-dosing metabolism was enhanced approximately 2-fold. Plasma levels of oestradiol were significantly suppressed by the lowest dose of PyG. Although higher doses appeared to achieve greater suppression this was not statistically significant in this small group of patients. There were no significant effects at any dose on the serum levels of cortisol, aldosterone, luteinising hormone, follicle stimulating hormone, prolactin, sex hormone binding globulin or thyroid stimulating hormone. There was a dose-related increase in 17 alpha-hydroxyprogesterone levels and a dose-related decrease in levels of dehydroepiandrosterone sulphate (DHAS). The androgens DHA, testosterone and androstenedione also were significantly suppressed with at least one of the doses of PyG. Synacthen tests did not support these changes being a result of inhibition of 17,20 lyase. It is possible that they are due to enhanced clearance of DHAS. Two patients experienced no toxicity throughout the study, whilst a total of four patients were withdrawn because of side-effects: one at 400 mg b.d., two at 800 mg b.d., and one at 1200 mg b.d. The most frequent side-effects were nausea and lethargy. One patient showed an objective response to treatment.

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 report a phase I/II study of the indole derivative, zindoxifene, an anti-oestrogen with intrinsic oestrogenic activity. We have treated 28 women with advanced breast cancer of whom 26 had received prior endocrine therapy. Oral zindoxifene doses ranged from 10 to 100 mg daily; doses were escalated in some patients. Twenty-five patients were assessed for response; the remaining three patients completed less than 3 weeks of treatment. There were no objective responses; disease stabilised in seven patients for up to 5 months and progressed in the remaining 18. Five patients (including three treated with tamoxifen) responded to subsequent endocrine therapy. Nausea, which was dose-limiting, affected half of the patients treated with 80 mg daily. Metabolites of zindoxifene were detectable in serum at all doses used, and sex hormone binding globulin (SHBG) levels showed a strong tendency to rise at the higher doses, indicating that zindoxifene is absorbed and has biological activity. We conclude that zindoxifene in the doses used in this study has only marginal therapeutic activity in the treatment of advanced breast cancer.

28 patients with polycystic ovary syndrome were treated for 12 months with the new preparation SH B 209 AE, consisting of 0.035 mg of ethinyl estradiol and 2 mg of cyproterone acetate. This was the first clinical trial of estroprogestational therapy on a homogeneous sample of women with polycystic ovary syndrome. Endocrine findings indicated a significant decrease in all hormonal parameters, the invariableness of prolactinemia, a considerable increase in sex hormone binding globulin (SHBG) at the 6th treatment cycle examination, a continuous significant decrease in 17 beta E2 and androstenedione from the 6th to the 12th treatment cycles. In terms of clinical findings, there was a significant decline in the severity of acne, seborrhea, and hirsutism during drug administration. The menstrual cycle in the 28 study subjects remained under control during treatment, and there were no pregnancies. Side effects such as weight gain, nausea, headache, and changes in libido were not reported. Overall, the findings of this study suggest that administration of the new monophasic contraceptive association SH B 209 AE can normalize endocrine patterns in polycystic ovary syndrome and improve its androgenic symptomatology. The low content of estrogen, the changes in clinical and hormonal parameters, the low incidence of side effects, and the good control of the menstrual cycle provided by this treatment make SH B 209 AE deserving of more widespread application.

A trial of a triphasic oral contraceptive in 13 women with polycystic- ovary syndrome is presented, backed up with data on levels of sex hormone binding globulin (SHBG), testosterone, androstenedione, 17-OH-progesterone and other hormones. This illness is really a hyperandrogenic response of the ovary secondary to high gonadotropin levels and unopposed estrogens with low SHBG. Only mediocre results have been reported with low-dose oral contraceptive treatment, compared to earlier high-dose pills. The pills used here contained 50 mcg levonorgestrel (LNG) with 30 mcg ethinyl estradiol (EE) for 6 days, 75 mcg LNG and 40 mcg EE for 5 days, and 125 mcg LNG with 30 mcg EE for 10 days. After 3 months of treatment LH levels fell from 29.7 to 3.6 mIU/m1; FSH fell from 12.3 to 2.6 mIU/m1, and the LH/FSH ratio decreased from 2.34 to 1.38. All androgens declined significantly (p0.01), into the normal range. Serum cortisol rose significantly from 16.9-36.7 mcg/100 ml. SHBG rose from 1.67-3.0 mcg/100 ml, the high limit of normal. Hirsutism and acne improved in all but 1 patient. 1 woman dropped out because of weight gain, and another because of nausea and headache. These results suggest that triphasic oral contraceptives may be safe and effective for chronic anovulatory syndrome.

A core design contraceptive vaginal ring (CVR) releasing 650 mcg of norethindrone acetate (NA) and 10, 20, 30 or 65 mcg of ethinyl estradiol (EE) daily was developed and tested in 99 women. The CVR inhibited ovulation well with 30 or 65 mcg EE. Vaginal bleeding was better controlled than in 23 control women using NA/EE oral contraceptives. Side effects were comparable to controls for the 20 and 30 mcg EE CVR. The 65 mcg EE CVR resulted in an unacceptably high level of nausea. The 20 and 30 mcg EE CVR caused an increase in serum HDL cholesterol and triglycerides. Total cholesterol was unchanged. Angiotensinogen and sex hormone binding globulin-binding capacity were increased in a subgroup of the 20 and 30 mcg EE CVR subjects, similar to that of 20 controls using EE/gestodene oral contraceptives. This new CVR offers an excellent contraceptive alternative with the best performance provided by the 30 mcg EE dose.

A core design contraceptive vaginal ring (CVR) with average daily release of 650 mcg of norethindrone acetate (NA) and 30 mcg of ethinyl estradiol (EE) inhibited ovulation and controlled vaginal bleeding well, but caused some nausea. This study was designed to minimally alter the dose of steroid to see if nausea could be reduced without loss of contraceptive efficacy. This 30/650 CVR was compared to a CVR releasing 20 mcg of EE and 1000 mcg of NA (20/1000) and another releasing 25 mcg of EE and 650 mcg of NA (25/650) in 69 subjects. Twenty-three subjects using an oral contraceptive containing NA/EE served as controls. Ovulation inhibition was excellent and comparable to the OC for all formulations. The CVR provided better control of vaginal bleeding than did the OC. Side effects were equivalent to the OC with the exception of a slight increase in nausea in CVR users. Lipid changes and globulin increases were comparable to oral contraceptive users. The 20/1000 CVR increased sex hormone binding globulin-binding capacity less than the other two CVRs. The performance of the three CVRs was not significantly different, but the 25/650 showed a trend of reduced performance relative to the other two formulations.

Oral contraceptives have been available for a little over 40 years and, during that time, many different formulations have been introduced. There have been dramatic dosage reductions of both the estrogen and progestogen components and various progestogens have been introduced over time. The properties of most progestogens used in oral contraceptives are very similar, differing mainly in potency. Oral contraceptives with progestogens having new and unique properties are needed. World-wide, around 20-30% of women of childbearing age use oral contraceptives and their use declines after the age of 35 years, with an accompanying increase in the rates of unintended pregnancy and elective termination. Incorrect use likewise gives rise to high unintended pregnancy rates. Use in Europe is higher than in other regions. Discontinuation because of unwanted effects and misperceptions is very common. Common misperceptions that prevent women from initiating oral contraceptive use are weight gain, cancer risks and that bleeding indicates a significant problem. Unwanted effects that commonly give rise to discontinuation are bleeding, nausea, weight gain, mood changes, breast tenderness and headaches. Discontinuation rates are high, particularly in the first year, and adolescents have the highest rates of discontinuation. Correct consistent use must be encouraged by taking pills at a regular time each day and by reinforcing that bleeding and other unwanted effects are not medically serious. Reinforcement of the non-contraceptive health benefits is very important and it needs to be emphasized that long-term use enhances these non-contraceptive benefits. Most non-contraceptive benefits are due to the progestogen component and its inhibition of ovulation. The new drospirenone-containing oral contraceptive (Yasmin, Schering AG, Berlin, Germany) offers the traditional non-contraceptive benefits; however, due to its unique antimineralocorticoid and antiandrogenic properties, new and unique benefits have been observed. Acne is well controlled, as would be expected from its inhibition of ovulation, antiandrogenic activity and lack of attenuation of the estrogen-mediated increase in sex hormone binding globulin. Its antimineralocorticoid activity gives rise to a reduction in fluid-related symptoms. The oral contraceptive containing 3 mg drospirenone with 30 microg ethinylestradiol DRSP/EE) has excellent efficacy since drospirenone is a potent progestogen, the corrected Pearl index being 0.09. This index is lower than those of many other oral contraceptives. Cycle control is excellent and comparable to that experienced with other oral contraceptives. A significant and consistent weight loss was seen with DRSP/EE compared to a reference preparation containing desogestrel. Day-to-day compliance and the duration of intake of an oral contraceptive are dependent on the woman's satisfaction with the pill she is taking. DRSP/EE meets these expectations and, with its new and unique non-contraceptive benefits, offers a real new choice to women.
