menogaril and Nausea

An early Phase II study with TUT-7 (menogaril), a new anthracycline antitumor antibiotic, was conducted in patients with various malignant tumors at 81 departments of 65 institutions nationwide. One course of TUT-7 treatment consisted of seven (7) or fourteen (14) consecutive days of administration at 75 or 100 mg/body/day with two-week drug withdrawal; at least two courses of treatment were given in principle. Among the 165 patients registered, 145 patients were eligible and 128 patients were evaluable for antitumor efficacy. In 11 patients with malignant lymphoma, one (1) had CR and five (5) had PR (54.5%); in three (3) patients with prostate cancer, one (1) had PR (33.3%); and in 12 patients with uterine cervical cancer, two (2) had PR (16.7%). Adverse drug reactions frequently observed were digestive organ disorders (anorexia and nausea/vomiting) and malaise. The abnormality in laboratory tests observed frequently was myelosuppression (leukopenia and neutropenia).

A late Phase II multicenter study with menogaril was conducted nationwide in patients with malignant lymphoma [non-Hodgkin's lymphoma (NHL), Hodgkin's disease (HD)], and ATLL, menogaril was orally administered at 100 mg daily after breakfast, for seven consecutive days with two- or three-week drug withdrawal, then menogaril administration was repeated. For malignant lymphoma, in 81 patients with NHL and 5 patients with HD registered, 70 and 5 patients were evaluable for efficacy, respectively. The efficacy rates were 32.9% (6 CRs + 17 PRs/70) for NHL and 20.0% (1 PR/5) for HD, respectively; that for the NHL patients with prior anthracycline antibiotic chemotherapy was 30.5% (5 CRs and 13 PRs/59). For ATLL, among the 16 patients registered, 15 were evaluable for efficacy, and the efficacy rate was 40.0% (2 CRs and 4 PRs/15). Adverse drug reactions frequently observed in the patients with malignant lymphoma and ATLL included bone-marrow suppression and gastrointestinal symptoms such as anorexia, and nausea/vomiting. With these results, menogaril was considered to be effective for the treatment of non-Hodgkin's lymphoma and ATLL.

Menogaril (7-con-O-methylnogarol) is a semisynthetic anthracycline analogue of nogalamycin that has shown good activity against a variety of experimental tumor systems as well as decreased cardiac toxicity when compared with doxorubicin in preclinical studies. Forty-one patients with refractory solid tumors received menogaril during a phase I trial at The Johns Hopkins Oncology Center (Baltimore). Menogaril was administered as an intravenous (IV) infusion on days 1 and 8 of a 28-day cycle in doses of 8 to 140 mg/m2. Eastern Cooperative Oncology Group (ECOG) grade 3 and 4 leukopenia was the principle dose-limiting toxicity and was occasionally accompanied by thrombocytopenia. Both WBC and platelet nadirs occurred between days 15 and 22. Anemia requiring transfusion was occasionally seen. Nonhematologic toxicities observed included frequent anorexia and malaise that was not dose related and postinfusion phlebitis that was dose related and occasionally dose limiting. Gastrointestinal toxicity and alopecia were infrequent and mild in severity. Three patients with cumulative doses of menogaril greater than 1,400 mg/m2 had no significant changes in ejection fractions as determined by serial gated blood pool scans. Two patients had greater than 10% decrements in ejection fractions without clinical changes at total doses of 128 and 288 mg/m2. One patient with prior anthracycline therapy and chest irradiation decreased her left ventricular ejection fraction from 52% to 30% and developed respiratory failure after two cycles of therapy in the setting of disease progression. No responses to menogaril therapy were observed. The recommended phase II dose for menogaril on this day 1 and 8 schedule is 140 mg/m2. A starting dose of 90 mg/m2 should be considered for heavily pretreated patients. In comparing results of this phase I schedule with those of other schedules, evidence for schedule-dependent toxicity differences should be sought.
