A clinical trial of a new semi-synthetic podophyllotoxin, VP-16, was undertaken in patients with primary lung cancer; 56 of the 81 evaluable patients had small cell carcinoma, 9 adenocarcinoma, 8 epidermoid carcinoma, 7 large cell carcinoma, and 1 adenosquamous carcinoma. A dose of 200 mg/body/day orally for 5 consecutive days was administered every 3 to 4 weeks. Partial response (PR) was attained in 19 out of 81 (23%) and PR + MR was 35 out of 81 (43%). PR and minor response (MR) were seen as follows; small cell carcinoma, 17 PR (30%), 13 MR; epidermoid carcinoma, 2 PR (25%), 1 MR; adenocarcinoma, 1 MR; adenosquamous carcinoma, 1 MR. The dose-limiting factor was leukopenia, while thrombocytopenia was experienced in 2 cases. Clinical toxicities noted were anorexia, nausea, vomiting, stomatitis, diarrhea and alopecia, but these were well tolerated in all cases. The result indicated that VP-16 has considerable efficacy in small cell carcinoma and epidermoid carcinoma of the lung and hence its usefulness in combination chemotherapy was suggested.

To exploit possible dose-response and combination drug synergism, 20 previously untreated patients with extensive-stage small-cell lung cancer (SCLC) received one or two courses of high-dose induction chemotherapy consisting of cyclophosphamide (100 mg/kg), etoposide (1,200 mg/m2), and cisplatin (120 mg/m2) (HDCEP). HDCEP was followed by four cycles of standard-dose cyclophosphamide (1,000 mg/m2), doxorubicin (40 mg/m2), and vincristine (1.4 mg/m2) (CAV). Response was determined after HDCEP and following CAV. Reevaluation included repeat bronchoscopy and chest computerized tomography (CT), as well as repetition of all initially abnormal studies. All patients were evaluable for response and toxicity. Overall response to HDCEP was 90%, with a complete response (CR) rate of 65% (95% confidence limits, 44% to 86%) and a partial response (PR) rate of 25% (95% confidence limits, 6% to 44%). All patients either maintained or improved their initial response while receiving CAV. Median duration of response was 6 months (range, 2 to 12 months) and median survival was 9.5 + months (range, 2 to 21 + months). All 37 courses of HDCEP were associated with leukopenia (less than 1,000/microL), 92% with thrombocytopenia (less than 20,000/microL), and 84% with fever of greater than 38.5 degrees C. Additional toxicities included bacteremia (24%), nausea and emesis (59%), mucositis (57%), diarrhea (38%), and hemorrhagic cystitis (5%). There were two treatment-related deaths due to infection. A third patient died 4 months after completing HDCEP with pulmonary fibrosis. Although response duration and median survival were not improved, HDCEP produced a high CR rate in ambulatory patients with extensive-stage SCLC.

Based on the overall results of a UFT phase II study made in 104 institutions in Japan from April of 1979 to September of 1980, there was a response rate of 27.7% with 3 CR cases and 49 PR cases out of 188 stomach cancer cases considered as evaluable according to solid cancer chemotherapy direct efficacy criteria. Other response rates were spleen cancer 25%, gallbladder cancer 25%, liver cancer 19.2%, colorectal cancer 25%, breast cancer 32% and lung cancer 7%. Side effects out of 551 cases were, loss of appetite 24.3%, nausea/vomiting 12.5%, diarrhea 11.1% and other digestive system symptoms mainly. The hematologic side effects were mild, being 6.9%. According to the UFT phase II study, in 438 evaluable cases followed for 5 years after testing, the results were analyzed in terms of therapeutic efficacy and survival time. In 185 stomach cancer cases, 50% survival time was 185 days, with CR + PR cases 336 days, MR + NC cases 183 days, and PD cases 97 days. Colorectal cancer showed a 50% survival time of 227 days in 54 cases, while that for 49 breast cancer cases was 505 days. Total Ftorafur (FT) results using the same criteria from the UFT phase II study revealed, from a comparison of dosage and disease type, that UFT did not enhance FT side effects; rather, it markedly increases effectiveness. Therefore, on the basis of its response rate and the survival time for the cases of digestive system cancer, UFT is considered an effective anticancer agent.

Diarrhea commonly occurs following the administration of cisplatin. BW942C, a pentapeptide, is a synthetic enkephalin shown to control castor oil-induced and traveler's diarrhea. To assess the safety and efficacy of BW942C in controlling diarrhea caused by cisplatin, 30 adults with lung cancer who had already experienced diarrhea (three or more loose bowel movements) during the 24-hour period following a prior cisplatin administration were randomized to receive either BW942C or placebo during the next cisplatin course. All patients received a concomitant antiemetic regimen including metoclopramide, dexamethasone, and lorazepam during all courses. Patients administered BW942C experienced less diarrhea (27% v 67%, P = .02). Twenty-seven percent of patients given the pentapeptide had loose bowel movements as opposed to 93% who received placebo (P = .0002). There were no significant differences in the incidence and degree of vomiting and other treatment-related side effects observed between the placebo and treatment groups. We conclude that oral BW942C is more effective than placebo in controlling diarrhea following cisplatin chemotherapy.

Clinical evaluation and kinetics in serum of cefoperazone (CPZ) in patients with lower respiratory tract infections have been conducted as a multicenter trial participated by 20 institutions in Kyushu area during a period of 8 months from October 1984 to May 1985. Mean serum CPZ levels up to 4 hours following the end of intravenous infusion of either 1 or 2 g CPZ remained higher than the MIC80 of CPZ against major causative organisms of lower respiratory tract infections such as H. influenzae, P. aeruginosa, K. pneumoniae, and S. pneumoniae. Serum half-lives of CPZ following intravenous infusion were prolonged in the elderly and in patients who showed moderate liver or kidney dysfunction, but did not exceed twofold of normal value. Clinical efficacy rates of CPZ were 82.9% (34/41) against pneumonia, 80% (4/5) against lung abscess, 88.9% (32/36) against acute exacerbation of chronic bronchitis, 66.7% (2/3) against panbronchiolitis, 100% (1/1) against acute bronchitis, and 85.7% (12/14), 64.3% (9/14) and 70.0% (7/10) against infections concurrent to chronic respiratory diseases, pulmonary emphysema and bronchiectasis, respectively. The overall efficacy rate was 81.5% (101/124). Bacteriological eradication rates against P. aeruginosa, H. influenzae and S. pneumoniae were 60% (6/10), 88.9% (8/9) and 100% (3/3), respectively. The overall eradication rate including polymicrobial infection was 67.5% (27/40). The clinical efficacy rate of CPZ in patients with underlying diseases such as lung cancer, pulmonary tuberculosis, and pneumoconiosis, etc. was not significantly different from the efficacy rate in patients without these underlying diseases. Of 20 patients who failed to respond to previous antibiotic treatments, 13 were effectively treated by CPZ. Adverse reactions occurred in 6.7% (11/164) of the patients, and consisted primarily of rash, fever, diarrhea and loose stool. Laboratory abnormalities were seen in 5 patients during the study. These included elevations of S-GOT and S-GPT, eosinophilia and neutropenia. CPZ is a very useful drug in the treatment of lower respiratory tract infections because of its excellent clinical efficacy and rare incidence of abnormal accumulations in sera following the recommended 2-4 g/day administration even in the elderly.

The clinical development of the second generation platinum complex iproplatin (CHIP) is reviewed. The compound was virtually non-nephrotoxic in preclinical toxicology studies and had myelosuppression as its dose-limiting toxicity in rats and dogs. A phase I study of 20-350 mg/m2 given every 3-4 weeks showed the compound to have myelosuppression as its dose-limiting toxicity in humans, with thrombocytopenia being the most prominent feature. Nausea and vomiting were almost universal, but were less severe than with cisplatin. Diarrhoea and skin rash were also noted but nephrotoxicity, neurotoxicity and ototoxicity were not seen. The maximum tolerated dose was 350 mg/m2, with or without pretreatment hydration. In pharmacokinetic studies three platinum-containing species were measured: total Pt, non-protein bound Pt and unchanged iproplatin. Plasma decay of total Pt was biphasic with a beta-phase half-life of 69.3 h. Plasma decay of unchanged iproplatin was monophasic with a half-life of about 1.17 h. Plasma decay of filterable Pt followed a monophasic pattern at low doses and a biphasic pattern at high doses. Urinary excretion of Pt was widely variable and incomplete. Early data from phase II studies indicate a high degree of activity in small-cell lung cancer; high activity in ovarian carcinoma has been reported by others.

An antiemetic combination of metoclopramide and methylprednisolone was administered to 16 lung cancer patients receiving cisplatin (80 cmg/m2) alone or in combination with other drugs. Metoclopramide was administered four times intravenously at a dose of 1.5 mg/kg. Methylprednisolone was administered three times intravenously at a dose of 125 mg. Sixteen patients received a total of 34 chemotherapy courses. No vomiting occurred in 70% of 34 chemotherapy courses and mild emesis (one or two vomiting episodes) occurred in 18% of chemotherapy courses. Side effects were minimal and included mild sleepiness (nine patients), diarrhea (three patients), and hiccups (three patients). It is concluded that a combination of metoclopramide and methylprednisolone is very effective in preventing cisplatin-induced vomiting.

Clinical efficacy of new fluorouridine derivative, FF-705, was studied in 108 patients with advanced malignant tumors. Partial responses were observed in 8 of 61 evaluable cases (13.1%): 4 of 9 patients with breast cancer, 1 of 19 patients with gastric cancer, 1 of 15 patients with lung cancer, 1 of 3 patients with kidney cancer and 1 of 1 patient with pancreas cancer. In the analysis of adverse effects of FF-705, gastrointestinal toxicity was major toxicity. Especially, diarrhea was observed in 41 of 108 patients (38.0%) within a total dose of 10 g shortly after drug administration.

Fifty-two patients with metastatic or recurrent non-small-cell lung cancer (NSCLC) were treated, during a phase II trial, with methylglyoxal-bis-(guanylhydrazone) (MGBG). Of the 44 patients who had adequate trials, 4 had partial responses (PR), for an overall 9% PR rate. Response durations ranged from 3 to 5+ months. Prior treatment with chemotherapy may have adversely affected response rate; 15% of previously untreated patients responded, compared to only 4% of previously treated patients. A syndrome of weakness and fatigue was the most serious side effect. Anorexia and weight loss, stomatitis, nausea and vomiting, diarrhea, and peripheral neuropathy were the other toxic effects. We conclude that MGBG has activity in NSCLC, especially in previously untreated patients, and further studies are indicated in that population.

A phase II study of KW 2083 [7-N-(p-Hydroxyphenyl)-Mitomycin C] was carried out in 14 cases of stomach cancer, 5 of lung cancer, 5 of colon cancer and 5 other types of cancer. KW 2083 was intravenously injected at a dose of 40 mg/body weekly in 26 cases. Among 23 evaluable cases, partial response was obtained in 6 cases (26%). The PR cases were 4 of stomach cancer and 2 of lung cancer, the former being all undifferentiated adenocarcinoma. Regarding hematologic toxicities, thrombocytopenia was the most principal toxicity and an important weak point of KW 2083. Thrombocytopenia (less than 75,000/mm3) was observed in 13 cases (50%). Recovery took about 4 weeks, but by that time 3 cases had still not recovered to 75,000/mm3. leukocytopenia (less than 3,000/mm3) was observed in 17 cases (65%). Concerning gastrointestinal symptoms, anorexia occurred in 11 cases (42%), nausea and vomiting in 11 cases (42%), diarrhea in 1 case and stomatitis in 1 case. T1/2 (beta-phase) of KW 2083 was half that of Mitomycin C.
