A phase I study of N4-behenoyl-1-beta-D-arabinofuranosylcytosine (BHAC) was conducted in 66 patients, 41 with solid tumors and 25 with hematological malignancies. The patients received either a 2-h single intravenous (i.v.) drip infusion (Schedule 1) or consecutive daily 2-h i.v. infusions (Schedule 2). In Schedule 1 the daily dose was initiated with 1.5 mg kg-1 which was escalated up to 7 mg kg-1. Side-effects were mild, and included nausea, vomiting, epilation, and hot flushes. Because of the presence of the solvent vehicle, HCO-60 and in consideration of the mechanism of action of BHAC, the dose escalation was stopped at 7 mg kg-1. In Schedule 2, the daily dose was started with 1.5 mg kg-1 which was escalated up to 8 mg kg-1 and given for 2-16 days. Myelosuppression was found to be dose-limiting toxicity. The maximum tolerated dose (MTD) in patients with non-hematological solid tumors was assumed to be 5 mg kg-1 daily X 5 days. The plasma disappearance curve of BHAC looked biphasic, and when 4 mg kg-1 of BHAC were administered the half-lives of the initial phase (t1/2 alpha) and the second phase (t1/2 beta) were calculated as 0.798 and 5.76 h respectively. In Schedule 2 complete remission was observed in 5 out of 21 patients with acute leukemia, one partial remission in Hodgkin's disease, and one 1-B response (Karnofsky) in thyroid papillary adenocarcinoma.

Since 1980 we have been carrying out a prospective randomized trial comparing tamoxifen with the combination of tamoxifen plus nandrolone decanoate in advanced breast cancer. The tamoxifen dose is 30 mg daily and the nandrolone decanoate dose 100 mg i.m. once a week for four weeks and thereafter every other week. 98 post-menopausal patients have been evaluated for the response. The number of patients is 49 in both groups. The overall response rates (CR + PR) to tamoxifen and tamoxifen plus nandrolone decanoate were not significantly different; in the tamoxifen group the response rate was 49% and in the combination group 45%. The mean time to progression in tamoxifen group is over 13 months and in tamoxifen plus nandrolone decanoate group over 12 months. Our results do not suggest a synergistic effect from combining tamoxifen and nandrolone decanoate treatments. The response rates to tamoxifen at different sites of metastases were as follows: bones 47%, soft tissues 56%, and viscera 48%. The respective figures with the combination therapy were 36%, 64%, and 40%. Both treatments were well tolerated and in no patient was withdrawal of the therapy necessary. Mild virilization and hoarseness were experienced by all patients treated with nandrolone decanoate. Side-effects associated with tamoxifen were rare, although five patients experienced nausea and two had hot flushes.

The possibility that the sudden discharge of thyrotropin-releasing hormone (TRH) in the brain triggers the climacteric hot flash was tested (double-blind) by an intra-venous, bolus injection of 500 microgram of TRH into 7 post-menopausal women and 1 menstruating control. Temperatures and sweating were recorded continuously on the recumbent subject during the 2-h test. None of the women reacted either subjectively or objectively to the placebo. TRH induced gastric pain in 1 post-menopausal subject. In another subject TRH elicited no response during the first test, but a week later in a second test it evoked transient nausea and a series of hot flashes with bursts of sweating. Published results of animal studies suggest that a higher dose of TRH would probably stimulate hot flash-like responses in more women.

Panic disorder is a chronic illness that affects at least 3 percent of the population. Panic disorder is associated with significant morbidity and an increased risk of suicide. Patients generally present with multiple somatic and psychologic complaints, including heart palpitations, chest pain, tremor, shortness of breath, choking, nausea or abdominal distress, dizziness, derealization, fear of losing control or going crazy, fear of dying, paresthesias, chills or hot flushes, headache, diarrhea, insomnia, chronic fatigue, anxiety and depression. To make the correct diagnosis, these symptoms must be evaluated carefully since they also occur with serious cardiovascular, pulmonary, endocrinologic and neurologic disorders. Many effective treatments are available, including tricyclic antidepressants, selective serotonin reuptake inhibitors, monoamine oxidase inhibitors, benzodiazepines such as alprazolam and clonazepam, and psychotherapy.

Ovulation-induction agents are commonly used in the treatment of infertility in patients with or without ovulatory disturbances. These agents include clomifene, bromocriptine, gonadotrophin preparations and gonadotrophin-releasing hormone (GnRH) and its analogues. Each agent is associated with its own specific adverse effects. Although many of these adverse effects are benign and self-limited, some, in particular those effects associated with gonadotrophins, may be life-threatening. Commonly noted adverse effects encountered with the use of pharmacological agents to treat infertility include the following. Clomifene has been associated with hot flushes, multiple gestation, visual disturbances, cervical mucus abnormalities and luteal phase deficiency. Similarly, most of the adverse symptoms associated with bromocriptine are short-lived, such as nausea and postural hypotension. On the other hand, gonadotrophin therapy, even when used appropriately, may lead to the ovarian hyperstimulation syndrome (which is occasionally life-threatening) and a high incidence of multiple gestation. Pulsatile GnRH therapy maybe accompanied by similar adverse effects to those of gonadotrophins, but with a far lower incidence. With regards to the long term safety of these medications, the relationship between fertility drugs and epithelial ovarian cancer is controversial, and causality has yet to be proven. Indeed, a working knowledge of the many adverse effects associated with these medications is essential to any physician prescribing ovulation induction agents, in order to ensure maximum patient safety, compliance and understanding.

In an open, non-randomized prospective phase-III-study the clinical and endocrine efficacy as well as the safety of leuprorelin acetate depot (Enantone-Gyn Monats-Depot) were investigated. The therapeutic results of 198 patients, gathered from 5 university institutions and two city hospitals, are reported. Endometriosis was classified by the revised American Fertility Society score (r-AFS) before and at the end of treatment. Serum levels of LH, FSH, prolactin, estradiol, progesterone, androstenedione, testosterone and leuprorelin acetate were determined by radioimmunoassay. The mean total r-AFS score changed as follows: before surgical intervention during first-look laparoscopy 21 +/- 24 at the end of first-look laparoscopy 15 +/- 19 at the end of the GnRH-treatment 8 +/- 14 During leuprorelin acetate treatment the r-AFS stages changed as follows: [table; see text] Using the scoring system 85.2% of the patients improved. Relief of dysmenorrhoea could be achieved in 95.4%, relief of dyspareunia in 64% and of pelvic pain in 69.4% of patients. Baseline hormone levels dropped sharply during treatment. [table; see text] Androstenedione, testosterone, blood pressure, body weight, haematological parameters, liver enzymes, creatinine, electrolytes and HDL-/LDL-cholesterin remained more or less unchanged. Side effects being hot flushes, sweating, sleeplessness, headache, nausea, depression and vaginal dryness were due to estradiol deprivation. In 135 patients resumption of menstruation occurred in 95.6% within the first three months post-treatment. 23 patients of whom 21 were judged as infertile, became pregnant immediately after treatment was finished. The study results confirm the efficacy of leuprorelin acetate depot in the treatment of even advanced stages of endometriosis.

In order to determine the usual dose in the first line therapy and a high dose in the second or third line therapy, a dose finding study of a novel antiestrogen NK 622 (toremifene citrate) was performed in patients (pts) with advanced or recurrent breast cancer. NK 622 was orally administered daily once for more than 8 weeks. In pts without previous drug therapy or in pts with cancer relapse after adjuvant therapy, the response rates [(CR + PR)/total] were 24.1% (7/29), 13.8% (4/29), 20.0% (1/5) and 40.0% (2/5) at doses of 40, 60, 120 and 240 mg/day, respectively. A 40 mg/day dose showed an objective response only in postmenopausal pts with estrogen receptor (ER) positive or unknown cancer. At a dose of 60 mg/day, some of the responding cases were premenopausal pts or pts with ER(-) cancer. In pts with cancer relapse during adjuvant therapy or in those with previous therapy and/or radiation, response rates were 25.0% (2/8), 0% (0/4), 13.5% (5/37) and 10.3% (4/39) at doses of 40, 60, 120 and 240 mg/day, respectively. Response was more frequent in pts with ER (+) cancer than with ER (-) cancer. The response rates in pts with previous therapy including tamoxifen (TAM) except medroxyprogesterone (MPA) were 14.3% (4/28) at a 120 mg/day dose and 6.1% (2/33) at a 240 mg/day dose. In pts with previous therapy including TAM, MPA and other antitumor agents, the rate was 18.2% (2/11) at a 120 mg/day dose. Side effects such as elevation of GOT, GPT and serum Ca level, decrease of hemoglobin, anorexia, nausea/vomiting, fatigue, dizziness and hot flush were observed. These side effects were moderate in grade and reversible. Dose dependency of side effects was not clearly observed in grade and incidence. From these results, NK 622 is expected to be a safe drug with efficacy in first line therapy at a dose of 40 mg/day and in second or third line therapy at a dose of 120 mg/day.

Efficacy and safety of NK 622 (toremifene citrate) were compared with tamoxifen (TAM) by a double blind test in patients with advanced or recurrent breast cancer. NK 622 and TAM were given orally for 12 weeks or more at daily doses of 40 and 20 mg/body, respectively. Eligible cases in NK622 and TAM groups were both 57 patients. No significant difference was observed in patient characteristics between either group. Response rates were 26.3% (8 CR and 7 PR, 15/57) in the NK 622 group and 28.1% (3 CR and 13 PR, 16/57) in the TAM group. Median values of duration to onset of CR were 91 days in the NK 622 group and 169 days in the TAM group. The duration was significantly shorter with the NK 622 group. Median duration of efficacy in CR and PR cases was 155 days in the NK 622 group and 154.5 days in the TAM group. Adverse effects were encountered in 7 patients (12.3%) of each of the 2 groups. The side effects were fatigue, hot flush, WBC decrease, abnormal values in liver function tests, etc. in the NK 622 group and anorexia, nausea, eruption, feeling of warmth, sweating, dry mouth, dizziness, abnormal values in liver function tests, etc. in the TAM group. Administration was discontinued in one patient with eruption and another patient with abnormal values of liver function tests in the TAM group, while there was no such case in the NK 622 group. Including the discontinued cases, the side effects were moderate and reversible in both groups. The patients in whom a drug was determined as useful or more numbered 24/57 (42.1%) in the NK 622 group and 23/57 (40.4%) in the TAM group. There was not significant difference between the 2 groups in the above results except the duration to onset of CR. From these results, NK 622 is expected to show comparable efficacy, safety, and usefulness in patients undergoing TAM treatment for advanced or recurrent breast cancer.

Tamoxifen is a nonsteroidal anti-estrogen frequently used in breast cancer therapy. Side effects to tamoxifen are uncommon (2%) but should be recognized and detected early by careful follow-up. Tamoxifen adjuvant therapy is absolutely indicated in postmenopausal breast cancer with estrogen-receptor--positive nodes. Recently, this indication has been extended to negative-node postmenopausal breast cancer. Mild acute side effects are the most frequent: hot flushes, menstrual irregularity, nausea, headache, vertigo, minimal modifications in blood cell counts. However, more serious accidents can occur. Increased risk of thromboembolism is linked to a fall in the level of antithrombin III. Ocular toxicity can occur. If such ocular lesions are diagnosed early enough, they can be cured by promptly withdrawing treatment. For patients given tamoxifen, there appears to be a small increase in risk of endometrial carcinoma, especially if the daily dose is > 30 mg. This over-risk requires adequate detection based on sufficient knowledge of the usual tamoxifen-related modifications in the endometrium. Physicians should also be aware of two favorable effects. Tamoxifen therapy leads to decreased cardiovascular morbidity and mortality in postmenopausal women and is associated with a significant increase in lumbar bone density. Risk of interaction with oral anticoagulants has been reported. We discuss here practical steps in the follow-up of women treated with tamoxifen.

Alniditan is a new 5HT1D receptor agonist, belonging to a different chemical class from sumatriptan and other indole derivatives used or being developed for the treatment of acute migraine. In a multinational double-blind randomized parallel-groups dose-finding trial, alniditan was given subcutaneously in hospital to patients with migraine headache of moderate or severe intensity at doses of 0.8 mg (n = 44), 1.0 mg (n = 42), 1.2 mg (n = 46) and 1.4 mg (n = 39). Efficacy, tolerability and safety of each dose were compared with those of placebo (n = 41). At 2 h after injection, headache was absent or mild in 83% and 82% of patients receiving alniditan 1.2 and 1.4 mg respectively compared with 39% for placebo (p < or = 0.002). Complete relief from headache was achieved in 72% (1.4 mg). Time to onset of relief decreased with increasing alniditan dose, and there was a dose-dependent reduction in headache recurrence rate: 25% of patients receiving 1.4 mg had responded by 15 min and headache recurred within 24 h in only 16% of the patients who initially responded to alniditan 1.4 mg, significantly less than for placebo (p = 0.018). Alniditan was superior to placebo in reducing the associated symptoms of nausea, phonophobia and photophobia, and in increasing patients' functional ability. The use of rescue medication was reduced when compared with placebo, and up to 87% of patients said that they would use the drug again if available. No clinically relevant cardiovascular effects were seen, nor consistent changes in clinical laboratory findings. Adverse effects, mainly head pressure, paraesthesia, and hot flushes, were reported by 34% of placebo-treated patients and up to 70% of patients receiving alniditan, but all doses were very well tolerated and no clear relationship with dose was established. Comparison with published findings suggests that alniditan 1.4 mg sc may have advantages over sumatriptan 6 mg sc in providing complete relief from acute migraine headache, and may be associated with fewer headache recurrences within 24 h. Both of these suggestions warrant further and larger trials of alniditan in acute migraine.
