One of a novel series of compounds (AMAPS or arylmethylaminopropanediols), 773U82-HCl has shown significant antitumor activity in in vitro and in in vivo tumor systems, but has less animal CNS toxicity than the lead compound in the same series (crisnatol). This study was designed to evaluate the pharmacokinetics, qualitative and quantitative toxicities of 773U82-HCl and to determine the recommended phase II dose (MTD) of 773U82-HCl given as a short infusion daily for 3 days every 3 weeks. Twenty-nine patients with refractory malignancies received 79 courses over 9 dose levels during this study. Doses ranged from 50 to 1060 mg/m2/d x 3 days. Due to the possibility of local hemolysis with concentrations > 1.5 mg/ml, drug was administered in solutions containing < or = 1.5 mg/ml. Because large volumes were needed at the higher dose levels, the infusion duration was increased from 2 hours to 4 hours. Mild to moderate nausea, vomiting, fatigue, dizziness and headaches were observed. Myelosuppression was the dose limiting toxicity. The recommended phase II dose and schedule was determined to be 800 mg/m2/d x 3d every 3 weeks. 773U82-HCl plasma concentration-time data were analyzed using a two-compartment pharmacokinetic model. The t1/2 beta averaged 6 hours and the total body clearance was 75.9 L/hr/m2. The volume of distribution (Vdss) was large, averaging 470 L/m2.

The aim of this phase I study was to exploit the potential efficacy of an alpha-2a-interferon (alpha-2a-IFN)-subcutaneous interleukin-2 (IL-2) combination, bypassing the toxicity usually associated with bolus or continuous infusion of IL-2. Therefore, nineteen patients with metastatic malignancies (7 melanomas, 6 renal cell carcinomas and 6 soft tissue sarcomas) were treated according to a dose escalating schedule of subcutaneous IL-2 combined with intramuscular alpha-2a-IFN for 5 days/week for 3 consecutive weeks. Cycles were repeated every 2-4 weeks unless disease progressed. Alpha-2a-IFN (3 MU/die) was given continuously, including during the rest weeks. IL-2 doses were started at 2 MIU/day/sqm and the MTD of 6 MIU/day/sqm was progressively reached. The dose of IL-2 was given twice daily every 12 hours. Both of the cytokines were administered in an outpatient setting. The main side effects were fever, chills, fatigue, hypotension, nausea and vomiting. Toxicity was correlated with IL-2 dose level. It was found to be mild at 2 and 4 MIU/day/sqm, while, in contrast, grade III toxicity was observed only at the highest dose of 6 MIU/day/sqm. However, this grade III toxicity was manageable and did not prevent continuation of the treatment as long as the dose was not increased above 6 MIU/day/sqm. Three patients, one with melanoma and two with renal cell carcinomas, obtained clinical partial responses. In eight patients, stable disease, and in the remaining eight, progression, were observed. The data suggest that the combined use of the two BRMs has manageable side effects and would seem to be efficacious. A phase II study at the recommended dose of 6 MIU/day is now necessary.

A phase I study of VP was undertaken using the methods of a single (40 cases; range of dose levels 30-540 mg/m2) and 5-day (41 cases; range of dose levels 40-140 mg/m2/day) intravenous administration. The dose-limiting toxicity of VP was moderate to severe leukopenia. MTD was estimated to be 540 mg/m2 for a single and 140 mg/m2/day for 5-day administration. The median days to WBC nadir from the start of therapy and to recovery from reaching the nadir were 10 and 10.5 for single, and 15 and 7 for 5-day administration, respectively. Thrombocytopenia was less frequent and less pronounced than leukopenia. Mild gastrointestinal disturbances and alopecia were frequently observed. Transient hepatic dysfunction, fever, headache, fatigue, dyspnea, hypotension, and pain along the vein were also encountered in a small number of patients. There were no cases with renal, neurologic or cardiac toxicity. Objective tumor regression was seen in one case each of IBL(CR), bladder cancer, non-Hodgkin's lymphoma and ATL (PR). The post-infusion plasma decay of VP in 4 cases given 80-120 mg/m2 by a single administration was biphasic with t1/2 alpha ranging from 0.13 to 0.39 h and t1/2 beta ranging from 3.33 to 4.85 h. No accumulation of VP was found in plasma after five repeated daily doses. Doses of 360-480 mg/m2 by single and 80-100 mg/m2/day by 5-day administration repeated every 3 to 4 weeks can therefore be recommended for phase II studies in good-risk patients.

LY188011 (Gemcitabine hydrochloride) is a new derivative of deoxycytidine. Phase I study was carried out by a cooperative study group. LY188011 was administered weekly for 3 consecutive weeks starting with an initial dose of 60 mg/m2 (1n) and then increasing the dosage to 1,000 mg/m2 (16.7n). Dose limiting factor was found to be myelosuppression (decreases of WBC, neutrophils and platelet), and MTD was considered to be 1,000 mg/m2. The nadir of WBC and platelet were observed after about 1-3 weeks. It took 1-2 weeks for their recovery. Other adverse reactions included fever, fatigue, anorexia, nausea/vomiting, anemia and transient elevations of GOT and GPT. However, those adverse reactions were mild. T1/2 rho of plasma concentration was about 19 min and the C5min was dependent on the dose. Anti-cancer effects were observed in one gastric cancer and two colon cancer patients. It is recommended that the dosing schedule for an early phase II study is 800 mg/m2 weekly for 3 weeks with 1 week of rest as one cycle, in multiple cycles.

The synthetic polynucleotide polyadenylic-polyuridylic acid (polyA:polyU) has shown antitumor activity in murine studies and human breast cancer. PolyA:polyU was evaluated in 25 cancer patients receiving weekly intravenous doses between 3 and 600 mg/m2. PolyA:polyU was well tolerated up to 600 mg/m2, with no doselimiting toxicity (all < grade 3). Side effects included mild elevation in temperature, fatigue, and mild hyperglycemia. No changes outside of the normal range in hematocrit, WBC count, platelet count, total bilirubin, or alkaline phosphatase were observed. Of 25 patients, 18 completed at least one cycle of 6 weeks, and 5 completed two cycles (median 6 weeks). Four patients had stable disease over 11-13 weeks of treatment, and no clinical responses were observed. At 24 h after the first treatment, there were no significant increases in biologic response (beta 2-microglobulin and neopterin in serum, or 2',5'-oligoadenylate synthetase in peripheral blood mononuclear cells). A small increase in beta 2-microglobulin was observed 24 h after the week 3 treatment (1.1-fold, p < 0.01). By the third week of treatment, 2-5A synthetase levels decreased slightly (to 80% of baseline, p < 0.01). No changes in cytokines IL-6, IL-12, tumor necrosis factor (TNF), or IL-2 receptor in serum were detected after 24 h of treatment. Thus, at these doses, polyA:polyU had no marked modulation on biologic responses in vivo, although this preparation significantly induced 2-5A synthetase in peripheral blood mononuclear cells in vitro. PolyA:polyU was well tolerated. An MTD was not reached but was greater than 600 mg/m2 on this weekly schedule.

Simultaneous exposure to retinoids and interferons can result in enhanced antiproliferative and differentiating effects on malignant lesions. We studied the toxicity and the potential efficacy of an association of high dose etretinate and Interferon-alpha (IFN-alpha) in squamous cell carcinomas of the lung, head and neck, the esophagus, cervix and the penis, as well as in transitional carcinomas of the bladder. The treatment consisted of etretinate (Tigason) 4 mg/kg/d on 2, 3, 4 and finally 5 consecutive days every other week and IFN-alpha (Roferon) 6 Mio IU sc. q.d. for 5 days every week. Of 24 patients enrolled, 23 were assessable for toxicity and 20 for response. With two occurrences of grade 3 cutaneous toxicity, the administration of etretinate (Tigason) 4 mg/kg/d on 5 consecutive days every other week and IFN-alpha (Roferon) 6 Mio IU sc. q.d. for 5 days every week was considered to be the MTD. Toxicity was mild otherwise, mostly at grades 1 and 2 level, causing fatigue, skin peeling and erythema, mucositis and cheilitis; 3 PR (partial response) and 8 SD (stable disease) were recorded. Of the responders, one patient had become resistant to cisplatin-based chemotherapy and the other two had at no time ever received systemic therapy. We conclude that the association of high doses of etretinate and IFN-alpha has moderate activity in squamous cell carcinomas, is well tolerated, and that IFN-alpha plays a role in the improved tolerance of the retinoid.

The novel folate analogue AG2034, which was designed as an inhibitor of GARFT (glycinamide ribonucleotide formyltransferase), was evaluated in this phase I study under the auspices of The Cancer Research Campaign, UK. AG2034 blocks de novo purine synthesis through inhibition of GARFT. A total of 28 patients with histologically proven intractable cancers were enrolled. AG2034 was administered as a short intravenous infusion once every 3 weeks. 8 dose levels ranging from 1-11 mg/m(2)were evaluated with patients receiving up to 6 cycles. Dose-limiting toxicities in the form of mucositis, diarrhoea and vomiting were observed at doses of 6 mg/m(2)and above. Significant levels of thrombocytopenia, neutropenia and anaemia were also recorded. Other sporadic toxicities included fatigue and myalgia. The MTD with this schedule of AG2034 was 5 mg/m(2). Most side effects occurred more frequently with cumulative dosing. In keeping with this, pharmacokinetic analysis revealed evidence of drug accumulation. The AG2034 AUC(0-24)increased by a median of 184% (range 20-389%) from cycle 1 to 3 in all 10 patients examined. No objective antitumour responses were observed in the study.

Depsipeptide (FR901228) is a bicyclic peptide isolated from Chromobacterium violaceum that has demonstrated potent in vitro cytotoxic activity against human tumor cell lines and in vivo efficacy against human tumor xenografts. The primary mechanism of action is through inhibition of histone deacetylase. Initial development was halted due to significant cardiac toxicity. Subsequent studies performed at the National Cancer Institute demonstrated administration without cardiotoxicity was possible by varying the schedule of administration. A phase I trial was designed to determine the maximum tolerated dose and toxicity profile when administered as a 4-hour infusion weekly x 3 with one week rest. 33 Patients with advanced, incurable cancers were enrolled into this trial and treated with doses of Depsipeptide ranging from 1 mg/m2 to 17.7 mg/m2. At doses above 5 mg/m2, we observed common symptoms of nausea, vomiting, fatigue, and anorexia. Subtle changes in ECGs were seen in several patients. However, no cardiac enzyme abnormalities or reduction in ejection fraction were observed. The MTD was defined as 13.3 mg/m2 with dose limiting toxicities being grade 3 thrombocytopenia and fatigue. Depsipeptide can be safely administered when given as a 4-hour infusion and further clinical trials are warranted.

A phase I study of gemcitabine (GEM) and docetaxel (TXT) combination chemotherapy was performed for unresectable non-small-cell lung cancer. Chemotherapy consisted of a fixed dose of GEM (1,000 mg/m2) on day 1, 8 and an escalated dose of TXT (50, 60, 70 mg/m2) on day 8 every 21 days, > or = 2 courses. Nine patients were entered (each dose level: 3 patients). Leukopenia, neutropenia, GOT increase, GPT increase, anorexia, fatigue, fever, and alopecia occurred, but no dose-limiting toxicity was found at any dose level and no MTD was reached. The recommended dose for the phase II study is GEM 1,000 mg/m2 and TXT 70 mg/m2 with consideration of application to outpatients and continuing courses.

We conducted a phase I study to evaluate the activity and tolerability of concurrent docetaxel and cisplatinum radiosensitization with hyperfractionated irradiation, in patients with advanced non-small cell lung cancer (NSCLC) and squamous cell carcinoma of the head and neck (SCCHN). Nine patients (5 stage III(A) and 4 III(B)) with NSCLC, and 15 with SCCHN (10 stage III and 5 IV) were treated with a b.i.d. hyperfractionated (HF) radiotherapy schedule. The normalized total dose for alpha/beta ratio = 10 Gy was 69.6 Gy for NSCLC and 80.5 Gy for SCCHN patients. The standard dose of cisplatin (10 mg/m(2)) was given combined to docetaxel on a weekly basis. The docetaxel starting dose level was 10 mg/m(2)/week and was escalated by 3 mg/m(2) increments in cohorts of 8 patients (5 SCCHN and 3 NSCLC). DLT (grade 3 malaise) was observed in 4 out of 8 patients treated at the 16 mg/m(2)/week docetaxel dose level. The 13 mg/m(2)/week docetaxel dose level was defined as the MTD causing grade 3 mucositis in 4 out of 8 patients. In total 4 (17%) patients developed grade 3 neutropenia. G-CSF support was given in 1/8, 4/8, and 5/8 patients treated at the 10, 13 and 16 mg/m(2) docetaxel dose levels respectively. Fatigue was the most common adverse event (5/24: 21%) and was responsible for more than 1 week treatment delay in 4 out of 8 patients treated at the 16 mg/m(2)/week docetaxel dose level. Nine (3 NSCLC and 6 SCCHN patients: 37.5%) had treatment delay of 1 week, while 7 (3 NSCLC and 4 SCCHN: 29%) had delays of 2 weeks for combined chemoradiation sequelae. Acute hypersensitivity reactions occurred in 3 (12.5%) patients, and grade 3 mucositis in 2/8, 5/8 and 6/8 patients, treated at 10, 13 and 16 mg/m(2)/week docetaxel dose levels respectively. The overall response rate was 79% (CI = 63-96%) with 33% and 53% CRs for NSCLC and SCCHN patients respectively. There were 3 deaths among 9 NSCLC and 4 among 15 SCCHN patients. Local and/or distant disease recurrences were shown in 4 NSCLC and in 6 SCCHN patients; 5 NSCLC and 9 SCCHN patients are alive with no evidence of tumor progression at 8.5 months mean follow-up time. Radiosensitization with docetaxel and cisplatin given concurrently with HF (b.i.d.) radiotherapy on a weekly basis is a promising approach and the recommended dose for further phase II studies is 10 mg/m(2)/week for both drugs. The antitumor activity shown was significant in both types of tumors. The incorporation of docetaxel in chemoradiotherapy regimens for future treatment of squamous cell carcinoma of the lung and head and neck, merits evaluation in phase II and III trials.
