Because of its unusual mechanism of action, docetaxel was selected for study in advanced soft tissue sarcomas of adults as part of a search for new active antisarcoma agents. Patients at least 18 years old with measurable histologically proven advanced nonosseous sarcomas were enrolled if they had ECOG performance status of < or = 2 and satisfactory leukocyte and platelet counts, and hepatic and renal function. Patients with Kaposi's sarcoma, mesothelioma, meningioma, embryonal rhabdomyosarcoma, and extraosseous Ewing's sarcoma were excluded, as were patients with brain or leptomeningeal metastases. Other specific contraindications to participation included other active cancer, previous or concurrent cancer chemotherapy or immunotherapy, and known allergy to the drug vehicle, polysorbate 80. Women of childbearing potential were required to have a negative pregnancy test. Following premedication with dexamethasone and diphenhydramine hydrochloride, docetaxel 100 mg/m2 as a concentrated solution containing 40 mg/ml in polysorbate 80 was infused over 1 h in 250 ml of either dextrose 5% in water or 0.9% saline. Treatment was repeated at 3-week intervals using standard definitions for objective responses. Up to two separate 25% toxicity directed dose reductions were permitted. Between May and December 1993, nine men and nine women registered (median age, 44 years). They received a total of 51 cycles of docetaxel (median, 2.5 cycles). Toxicity included moderate leukopenia (median first cycle nadir, 1.5 x 10(9)/L) but no significant thrombocytopenia. Alopecia, diarrhea, nausea, vomiting, and anorexia were common side effects. Fever, minor skin rashes, stomatitis, and edema were also observed. One drug-related death occurred in a neutropenic patient. One partial regression was observed (5.9%, 95% C.I. 0.15-28.7%) among the 17 eligible patients in a patient with metastatic uterine leiomyosarcoma.

CI-980 is a synthetic mitotic inhibitor that binds to the colchicine binding site of tubulin. It demonstrates broad activity against human and murine tumor models and shows no cross resistance with tumor models whose mechanism of resistance is mediated by P-glycoprotein (MDR-1). A phase I study was completed in 25 patients with solid tumors using a 24-hour infusion schedule, with courses repeated every 3 weeks. Eight dose levels were tested between 1.2 and 15.6 mg/m2. The maximum tolerated dose was 14.4 mg/m2. Neutropenia was dose-related but not dose-limiting; thrombocytopenia was infrequent. CNS toxicities were dose-limiting and consisted of dizziness, headache, loss of coordination, loss of consciousness, nervousness, and other symptoms. These events occurred near the end of the infusion and were reversible, usually within 24 hours. One patient who was to be treated at dose level 8 (intended dose was 19.2 mg/m2; actual dose was 15.6 mg/m2) became encephalopathic prior to completion of the infusion. Other adverse events included gastrointestinal toxicities (nausea, vomiting, anorexia, constipation, stomatitis, dyspepsia, bleeding, cheilitis), IV site erythema, fever, and fatigue. A partial response was observed in one patient with colon cancer and reductions in CA-125 levels were observed in 2 patients with ovarian cancer. Pharmacokinetics were linear and dose-proportional. Results indicate high systemic clearance and wide tissue distribution. Mean pharmacokinetic parameter values: T1/2 = 5.52 hours, plasma clearance 1163 mL/min/m2, and Vdss 376 L/m2.

We have conducted Phase I study of a novel oral antitumor agent of fluorinated pyrimidines, S-1, in which tegafur (FT) is combined with two classes of modulator, 5-chloro-2,4-dihydroxypyridine (CDHP) and potassium oxonate (Oxo) at a molar ratio of FT:CDHP:Oxo = 1:0.4:1 as a multi-center study with 16 institutions nationwide. Two administration methods, once and twice daily administrations, were evaluated. As a result, MAD was determined as 150 mg/body/day approximately 200 mg/body/day and 75 mg/body x2/day approximately 100 mg/body x2/day, respectively. DLF was myelosuppression, mainly consisting of leukopenia in the two administrations. Most adverse reactions observed, including myelosuppression, disappeared by discontinuation of administration, and recovery was in about 2 weeks. Adverse reactions other than myelosuppression which induced the discontinuation were rash and vomiting. Other adverse reactions observed were anorexia, malaise, diarrhea and stomatitis. Diarrhea and stomatitis were mild (Grade 1), except those observed at a dose of 200 mg/body/day, and did not induce discontinuation of administration. Based on these findings and pharmacokinetic evaluation, the recommended dose and administration for Early Phase II studies were determined as twice daily administration of 75 mg/body for 28 consecutive days with 14 days rest (1 course).

Three specific pathogen-free cats experimentally infected with feline immunodeficiency virus (FIV) strains Petaluma, TM1 and TM2, respectively were observed for over 8 years. Without showing any significant clinical signs of immunodeficiency syndrome (AIDS) for 8 years and 4 months of asymptomatic phase, the Petaluma-infected cat exhibited severe stomatitis/gingivitis, anorexia, emaciation, hematological and immunological disorders such as severe anemia, lymphopenia, thrombocytopenia, and decrease of CD4/CD8 ratio to 0.075, and finally died with hemoperitoneum at 8 years and 8 months post-infection. Histopathological studies revealed that the cat had systemic lymphoid atrophy and bone marrow disorders indicating acute myelocytic leukemia (aleukemic type). Plasma viral titer of the cat at AIDS phase was considerably high and anti-FIV antibody titer was slightly low as compared with the other FIV-infected cats. In addition, immunoblotting analysis using serially collected serum/plasma samples of these cats revealed that antibodies against FIV proteins were induced in all the infected cats, however in the Petaluma-infected cat anti-Gag antibodies disappeared during the asymptomatic period. These results suggested that plasma viral load and anti-FIV Gag antibody response correlated with disease progression, and supported FIV-infected cats as a suitable animal model of human AIDS.

In developing new anticancer agents, the most important thing is the balancing of antitumor activity and toxicity. To achieve high activity and low toxicity, S-1 was designed, in which tegafur, prodrug of 5-FU, was combined with two classes of modulators. CDHP, inhibitor of 5-FU degradation in liver and Oxo, inhibitor of 5-FU phosphoribosylation in digestive tract, respectively. This cooperative study with 15 nation-wide institutes was conducted to evaluate the antitumor activity and toxicity of S-1 in patients with advanced head and neck cancer from Jan. 1994 to March 1996 in Japan. Out of 26 patients, CR was achieved in 1 and PR in 11 with a response rate of 46.2%, while adverse events of grade 3 were as follows: hemoglobinemia (7.7%), leukocytopenia, neutropenia, stomatitis and anorexia (3.8%), each. Neither grade 4 adverse event nor treatment-related deaths were observed. Based on these findings, it was concluded that S-1 is a useful anticancer agent with the low grade toxicities for treatment of the patients with advanced head and neck cancer, and the effects of CDHP and Oxo found in preclinical studies might be also reflected in these results.

Treatment for metastatic melanoma is limited by low response rates to single- or combination-agent chemotherapy. Recent studies have examined the role of biologic modifiers and differentiating agents. This phase II study examined the efficacy and toxicity of combining alpha-2b-interferon (IFN alpha) and 13 cis retinoic acid (cRA) in the treatment of metastatic malignant melanoma. Thirteen patients were treated with IFN alpha (5 x 10(6) units/m2 three times weekly) and cRA (1 mg/kg per day). One patient with lung and adrenal metastases had a partial response 6 months in duration and two patients had stabilization of lung metastases for 2 months. All other patients had progressive disease. Toxicity was substantial with all patients experiencing Eastern Cooperative Oncology Group grade 1-2 fatigue, myalgias, anorexia, stomatitis, and cheilitis. In addition, serum cholesterol and triglycerides were elevated in all patients. Seven patients required 50% dose reductions because of hypertriglyceridemia, fatigue associated with a significant decline in performance status, and severe stomatitis with anorexia and weight loss. One patient discontinued therapy because of a decline in performance status. This study suggests this combination of cRA and IFN alpha is inactive in the treatment of metastatic melanoma and is associated with substantial toxicity.

The efficacy and toxicity of chronic administration of oral etoposide was evaluated in 61 patients with inoperable non-small-cell lung cancer (NSCLC). Ten patients received previous chemotherapy, 15 received radiotherapy, and one received both treatments. Twenty-four patients had concurrent cardiac and/or pulmonary impairment, which precluded more intensive treatment. Etoposide was given orally, 100 mg daily for 7 consecutive days and consequently 100 mg every other day for 14 more days in a 28-day schedule. Partial response was observed in 17 patients (28%; 95% confidence interval, 17-39%) and stable disease in 21 (34%). The median duration of response was 6 months (range, 2-34 months). The median survival for responders was 22 months and that of nonresponders was 7 months (p < 0.001). The median survival for all patients was 9 months (range, 1-35 months; 95% confidence interval, 5.69-12.31%). Toxicity was acceptable. Other than alopecia, which was observed in all patients, myelotoxicity was the most common toxicity--particularly leukopenia, which was severe in nine patients. Other less common toxicities included nausea and vomiting, stomatitis, anorexia, and neurotoxicity and were mild. No treatment-related deaths were observed. In conclusion, the regimen was effective and well tolerated with significant survival benefit for the responders. It represents an interesting therapeutic approach, especially in the elderly.

We treated 20 women with locally advanced breast cancer between January 1991 and September 1996. The treatment regimen included 4 cycles of intensive doxorubicin (30 mg/m2/d on 3 consecutive days every 2 weeks with G-CSF support), followed by appropriate surgery, followed by high dose therapy with cyclophosphamide, carboplatin and thiotepa (STAMP V, CTCb). Of the 20 patients, seven presented with inflammatory breast cancer, three with Stage IIIB, seven with stage IIIA, one with multifocal Stage IIB and two with Stage IV M1 (ipsilateral supraclavicular lymph node involvement) (including one who had an inflammatory primary) disease. Six patients had not undergone mastectomy at the time of entering the protocol. These six received the doxorubicin in a neoadjuvant fashion and were thus evaluable for tumor response. The remaining 14 received doxorubicin as adjuvant therapy prior to intensification and transplantation. All patients underwent local-regional radiation therapy and were placed on oral tamoxifen. Doxorubicin was well tolerated in this schedule with all but three patients receiving all their cycles on schedule. Both BM and PBPC were easily collected after this regimen and, when reinfused, resulted in the prompt recovery of granulocytes (median 11 days to 500 absolute granulocyte count) and platelets (median 13 days to 20,000 platelets). The six patients who received doxorubicin prior to mastectomy all had major clinical responses, but were found to have microscopic focii of breast cancer in the mastectomy specimens. The overall treatment was well tolerated with the exception of one treatment-related death (5%). The overall and relapse free survival are 70% and 58% respectively with a median follow-up of 40 months (range 12-74 months). When the Stage IV patients are censored, the relapse-free survival rate is 69%. In the bone marrow transplant phase of treatment, the major non-hematologic toxicities were stomatitis (70%) and anorexia requiring parental nutrition (75%).

The purpose of this study was to determine the maximum tolerated dose and dose-limiting toxicities of 5-fluorouracil (5-FU) when administered concurrently with recombinant IFN-alpha using four continuous infusion (CI) dosing schedules of 5-FU. Forty-five patients with advanced or refractory cancers were treated with 5-FU by CI, plus IFN during the infusion only, by one of four schedules: schedule A: 24-h 5-FU infusion repeated weekly, 9 x 10(6) units IFN x 2 doses weekly; schedule B: 48-h 5-FU infusion repeated weekly, 9 x 10(6) units IFN x 4 doses weekly; schedule C: 5-day 5-FU infusion repeated every 3 weeks, 9 x 10(6) units IFN three times weekly; and schedule D: 21-day 5-FU infusion, repeated after 7 days off therapy, 9 x 10(6) units IFN three times weekly. At least three patients were treated at all dose levels. Doses of 5-FU were escalated to the next level if less than one half of the patients at a given level developed grades 2-4 toxicity. The maximum tolerated dose for 5-FU was 2150 mg/m2/week for schedule A (24-h CI), 2350 mg/m2/week for schedule B (48-h CI), 750 mg/m2/day for schedule C (5-day CI), and 175 mg/m2/day for schedule D (21-day CI). Median delivered dose intensities at these levels were 1788 mg/m2/week for schedule A, 2192 mg/m2/week for schedule B, 1250 mg/m2/week for schedule C, and 593 mg/m2/week for schedule D. The dose-limiting toxicities were hematological and gastrointestinal (stomatitis, diarrhea, nausea, anorexia) for schedules A and B and gastrointestinal (mostly stomatitis) for schedules C and D. Severe fatigue due to IFN was rare. Responses correlated with toxicity >/= grade 2, but not with increased dose intensity. Responses were noted in several tumor types on schedules A, B, and D. 5-FU can be combined with IFN using 24- and 48-h high-dose and long-term low-dose CI schedules, with large differences in dose intensity at maximum tolerated dose. Shorter infusions produce less mucosal and more hematological toxicity. Tumor responses were seen on both short- and long-term CI schedules. Future studies can establish the efficacies of these new schedules of 5-FU/IFN administration in specific tumor types.

We conducted multi-site early phase II trial or oral etoposide administered for 21 consecutive days in patients with cervical or ovarian cancer in cooperation with 19 institutes. Fifty mg/body of oral etoposide was administered daily for 21 consecutive days. Cycles were repeated every 28 days. In cervical cancer, 24 patients were enrolled and 17 of them were evaluated. The overall response rate including CR and PR was 23.5% (4/17). In ovarian cancer, 18 patients out of 21 enrolled were evaluated. The overall response rate was 16.7% (3/18). The primary toxicity observed was myelosuppression such as leukopenia, neutropenia, hemoglobin decrease and thrombocytopenia. Other adverse effects were anorexia, nausea, vomitting, fatigue, alopecia and stomatitis. From these results we concluded that oral etoposide administered for 21 consecutive days was effective against cervical cancer.
