4'-(9-Acridinylamino)methanesulfon-m-anisidide (m-AMSA, NSC 249992), an acridine derivative, was given to 28 patients with solid tumors and one patient with Hodgkin's disease in a Phase I clinical trial. The dose schedule used was a single dose given every 14 days for three doses. The amount given ranged from 10 to 120 mg/sq m/dose. Dose-limiting toxicity was moderate to severe leukopenia which occurred at and above 70 mg/sq m. Thrombocytopenia was infrequent and did not require transfusion. Nonhematological side effects were mild and included nausea, vomiting, local irritation, and fever. Antineoplastic activity was noted in liposarcoma, adenocarcinoma of unknown primary origin, and squamous carcinoma of unknown primary origin (one patient each). Pharmacokinetics studies were done in 19 patients. Total m-AMSA and free m-AMSA concentrations showed a biphasic distribution with an initial rapid phase of t1/2 = 10 to 15 min for both, and a second slow phase of t1/2 = 8 to 9 hr for total m-AMSA and 3 hr for free m-AMSA. Phase II studies with m-AMSA, in hematological cancers are warranted, since its most consistent effect is on leukocytes. The recommended dosages for solid-tumor Phase II studies are 70 mg/sq m for good-risk patients and 50 mg/sq m for poor-risk patients, given as a single dose every other week, or 120 mg/sq m for poor-risk patients for the single-dose every-3-week schedule.

Twenty-six patients with relapsed or drug-resistant cancer were treated with a combination of oral etoposide (300 mg day-1 for 3 days) and high-dose oral tamoxifen as a potential modulator of drug resistance (480 or 720 mg day-1 for 6 days beginning 3 days before etoposide). One patient with relapsed high-grade lymphoma and one with adenocarcinoma of unknown primary site has a partial response. Toxicity consisting of nausea, vomiting and subjective dizziness, unsteadiness of gait and malaise occurred during tamoxifen treatment. Serum levels of tamoxifen averaged 3-3.5 microM on day 4 of all courses of treatment at both 480 and 720 mg day-1. N-desmethyltamoxifen levels were lower than tamoxifen during the first course (2 microM) but increased to equal tamoxifen levels during the second course. Didesmethyltamoxifen levels remained below 1 microM. In vitro, both tamoxifen and the standard modulator of multidrug resistance, verapamil, produced minor enhancement of etoposide cytotoxicity in the MCF-7 wt cell line but produced no enhancement with any other cell line. High, intermittent doses of tamoxifen can be given with acceptable toxicity and produce serum levels that have been shown to modulate drug resistance in vitro. In vitro, however, such levels have no significant effect on etoposide cytotoxicity towards a range of wild-type and MDR cell lines.

A phase I clinical study of tegafur (ftorafur) was conducted in 29 patients with various advanced solid tumors. To evaluate its efficacy and toxicity, the initial dose of 0.5 g/m2/day x 21 days at 3-week intervals was progressively increased to a maximum dose of 1.5 g/m2/day. Tegafur was administered orally in two or three divided doses. Diarrhea was the dose-limiting toxic effect and occurred more often in patients with abnormal pretreatment liver function. Nausea occurred in about one-half of the patients, but vomiting was infrequent. Skin rash and mucositis occurred in 10% and 7% of the patients, respectively. Neurologic toxic effects of tegafur were infrequent and mild. The hematologic toxicity of tegafur was minimal. Antitumor activity could be evaluated in 21 patients with measurable disease. One complete and three partial responses were observed in four of 17 patients who had adenocarcinoma of unknown primary origin. All responses occurred at doses greater tan or equal to 1.0 g/m2/day. The recommended dose of tegafur for this schedule of administration is 1.0 g/m2/day.

The aim was to perform a broad phase II and pharmacokinetic study of methoxymorpholino-doxorubicin (MMRDX), a drug active against multidrug-resistant tumour cells in vitro when given by i.v. bolus at 1.5 mg m(-2) every 4 weeks, in metastatic or unresectable solid tumour patients with known intrinsic drug resistance. Patients received a maximum of six cycles. Plasma, urine and leucocyte MMRDX and its 13-dihydro metabolite pharmacokinetic analysis was performed in patients without liver metastases. Patients (n = 48, 21 NSCLC, 19 renal cell, three head and neck tumour, three cervical cancer and two adenocarcinoma of unknown primary) received 132 cycles of MMRDX. Common toxicity criteria (CTC) grade III/IV thrombocytopenia (12% of cycles) and neutropenia (27% of cycles) occurred with median nadir on day 22. Transient transaminases elevation > grade III/IV was observed in 7% of cycles, late and prolonged nausea > or = grade II in 34% and vomiting > or = grade II in 39%. In two patients, the left ventricular ejection fraction was reduced > or = 15%. Of 37 evaluable patients, one out of 17 NSCLC had a partial response. Mean (+/- s.d.) MMRDX AUC0-infinity calculated up to 24 h after dosing was 20.4 +/- 6.2 microg h l(-1) (n = 11) and t(1/2, gamma) was 44.2 h. Mean plasma clearance (+/- s.d.) was 37.2 +/- 7.3 l h(-1) m(-2) and volume of distribution 1982 +/- 64 l m(-2). MMRDX leucocyte levels 2 and 24 h after infusion were 450 to 600-fold higher than corresponding MMRDX plasma levels. In urine, 2% of the MMRDX dose was excreted unchanged, and 2% as metabolite. The main side-effects of 1.5 mg m(-2) every 4 weeks of MMRDX are delayed nausea and vomiting and haematological toxicity. MMRDX is characterized by extensive clearance and rapid and extensive distribution into tissues. A low response rate was observed in patients with tumours with intrinsic chemotherapy resistance.
