A clinical trial of the oral form of VP 16-213 (NSC-141540), a semisynthetic podophyllotoxin, was undertaken. In 20 patients, treatment was started at 200 mg/day p.o. for 5 days; courses were repeated after a rest period of 16 days. Five patients were treated at the same dose, repeated with only 9-day rest periods. Subsequently, 65 patients were given 300-400 mg/day for 5 days, with rest periods of 9 days between courses. The side effects encountered included anorexia, nausea and vomiting, stomatitis, diarrhea, leukopenia, thrombocytopenia, alopecia, and pruritus. Substernal discomfort with or without palpitations was reported by 18 patients; no explanation for this symptom could be found. No complete remissions (CR) were observed. Parital remissions (PR) and improvement (IMP) were seen as follows: small cell carcinoma, lung (10 patients)--2 PR, 3 IMP; adenocarcinoma, lung (4 patients)--1 PR; alveolar cell carcinoma, lung (1 patient)--1 IMP; mesothelioma (4 patients)--1 IMP; ovarian cancer (12 patients)--3 PR, 3 IMP; breast cancer (20 patients)--4 IMP; colon cancer (8 patients)--2 IMP; bladder cancer (4 patients)--2 IMP; histiocytic lymphoma (7 patients)--2 PR, 3 IMP; chronic myeloid leukemia (1 patient)--1 IMP.

Yoshi 864 was given i.v. push daily times 5 with 6 weeks' followup. Dose escalation was from 0.25 mg/kg to 2.7 mg/kg. Toxicity and effectiveness were first seen at 1.5 mg/kg. Twenty-five courses were given to 16 patients at or above this level. In 16 of 22 courses, exclusive of CML, thrombopenia and/or leukopenia occurred. Mean platelet and WBC nadirs occurred on day 24 and 29 with recovery taking 1-2 weeks and 2-3 weeks respectively. Hb fell in 11 courses. At 2.7 mg/kg, nausea and vomiting lasting 6-12 days occurred in 3 of 7 courses; during 5 coures patients slept 20 hours a day, and 1 was comatose for 2 days. Two patients with squamous cell carcinoma and 1 with an unknown primary responded. Both patients with CML had clinical remissions. It is recommended that a cooperative Phase II Study in a broad spectrum of human solid tumors including lymphomas and chronic myelocytic leukemia be undertaken at a dose level of 2 mg/kg.

Two hundred and eight acceptable patients were treated with Yoshi 864 (2 mg/kg/day by iv push X 5 days repeated once every 6 weeks). Toxicity was minimal. There was an overall response rate of 11%. Cross resistance with other alkylating agents may not be present. Because of its lack of toxicity, Yoshi 864 should be further evaluated in chronic myelocytic leukemia, lymphomas, and carcinomas of the ovary and bladder where significant responses were seen. It should also be evaluated in combinations as a replacement for other alkylating agents which cause more nausea and vomiting.

Thirteen leukemic patients with disease refractory to conventional chemotherapy were treated with 1.0 to 7.5 g/m2 of Cytosine Arabinoside (Ara-C) over 29 drug cycles. Drug infusions were spaced at 12-hour intervals; a maximum of four doses was administered over 36 hours. After single dose tolerance had been established, three or four dose cycles were given at 2- to 30-day intervals. There were three partial remissions (PR) and one complete remission (CR) in a treatment group of four patients with AML, five with ALL, two with lymphoma converted to leukemic phase, one CML in blast crisis, and one promyelocytic leukemia. Five of the patients were septic and considered terminally ill at the time of treatment. All other patients had evidence of drug responsiveness. The nadir of the white count occurred from 3 to 12 days after treatment, with subsequent recovery of the peripheral granulocyte count between days 12 and 28. Toxicity included nausea and vomiting (GI symptoms) in twelve patients, central nervous system (CNS) disturbances in eight patients, one episode of inappropriate antidiuretic hormone syndromes (SIADH), one of hyperuricemia, and fever in eleven patients. There was no evidence of hepatic or renal dysfunction. These high doses of Ara-C appear useful for treatment of patients with refractory leukemia. Hospitalization is brief and toxicity acceptable.

The effect of hydroxyurea in 35 patients with chronic granulocytic leukemia (CGL), who either had entered an accelerated phase of the disease or had experienced excessive myelosuppression following alkylating agents, was studied. By either intravenous or oral administration, the drug was successful in reducing peripheral leukocyte and blast counts in all cases and in reducing splenomegaly in 13 of 17 patients. The median duration of disease control was 75 days in myeloproliferative acceleration and 27 days in frank blastic transformation. Mild nausea and vomiting were experienced by most patients, but reversible bone marrow suppression occured in only three patients. The drug proved useful in 19 patients who demonstrated myeloproliferative acceleration, especially in controlling excessive leukocytosis and/or thrombocytosis. Rapid reduction of an elevated blast cell count was achieved in nine patients who presented in blastic crisis, in an attempt to eliminate the associated risk of cerebral vascular leukostasis. Five patients who required treatment for their disease following splenectomy in the chronic phase were also well controlled. Hydroxyurea appears to have a definite role in the management of these hematologic complications of CGL.

Homoharringtonine (HHT) is a cephalotaxine alkaloid with reported efficacy in acute myelogenous leukemia (AML). In a phase II trial, we evaluated HHT 5 mg/m2 by continuous infusion daily for 9 days in patients with relapsed or refractory acute leukemia and blastic phase of chronic myelogenous leukemia (BLCML). Sixty-six patients were entered. There were 40 males and 26 females with a median age of 41 years (range 15-81). Of 43 patients with relapsed AML, seven achieved a complete remission (16%, 95% confidence interval 5%-27%). Although 11 patients with AML primarily resistant to an anthracycline/cytarabine combination did not respond, two of three patients primarily resistant to low-dose cytarabine achieved complete remission. No patients with acute lymphoblastic leukemia, biphenotypic leukemia, or BLCML responded. Hypotension during the administration of HHT was the most difficult toxicity encountered, requiring multiple interruptions of therapy in several patients and the administration of intravenous saline. Fluid retention and weight gain occurred in 29% of patients. Transient asymptomatic hyperglycemia was observed in 63% of patients. Other toxicity was mild and included nausea and vomiting, diarrhea, mucositis, hepatic dysfunction, and cardiac arrhythmias. As expected, severe myelosuppression occurred in all patients. HHT is well tolerated, but with unique problems associated with administration. It has demonstrable efficacy in pre-treated patients with AML, but its role in the treatment of this disease remains to be defined.

We used intermediate doses of Ara-C (IDAra-C) in the treatment of 15 patients with chronic myelogenous leukemia (CML) in blast crisis and, combined with hydroxyurea, in 20 CML patients in accelerated phase. Patients with blastic CML received intensive 5-day courses of IDAra-C 600 mg/m2 every 12 h as a 2-h infusion. Of 15 patients, three achieved complete response (CR) and three partial response (PR), for an overall response rate of 40 per cent. All patients developed severe leukopenia and thrombocytopenia, and two died in hypoplasia. Except nausea and vomiting requiring medication, other nonhematologic toxicities were uncommon. Median response duration was 4 months (range 1 to 7 months). Survival was 5 months for responders and 1.5 months for nonresponders. Patients with CML in accelerated phase were treated with two-day courses of IDAra-C 600 mg/m2 every 12 h by 2-h infusion, every two-three weeks. Daily hydroxyurea 1-1.5 g/day was administered between courses. Of 20 patients, 15 (75 per cent) achieved a good PR with rapid improvement of the symptoms of disease acceleration. The median duration of response was 11 months (range 3 to 38 months); duration was over 24 months in five patients. The median survival from the start of IDAra-C was 13 months for responders and 3.5 months for nonresponders. We conclude that IDAra-C is an effective approach for CML in terminal phase. Its use in 5-day induction courses for blast crisis CML has a response rate comparable to that achieved with high-dose Ara-C. In patients in accelerated phase, the combination of short courses of IDAra-C with hydroxyurea is a well-tolerated treatment able to improve substantially the clinical and hematologic symptoms of disease progression.

Carboplatin (CBDCA) is a second-generation platinum drug that has been shown to be useful when used as a continuous infusion in treatment of refractory adult leukemia. We report on the effectiveness of continuous infusion CBDCA, 300 mg/m2/d x 5 days, as evaluated in nine patients with secondary acute nonlymphocytic leukemia (ANLL) (seven previous myelodysplastic syndrome and two treatment-associated ANLL), three ANLL patients in first relapse, six refractory ANLL, and nine patients with blastic phase of chronic myelogenous leukemia (BP-CML). All patients were considered assessable. The response rate was 44% (eight complete remissions [CRs], four partial remissions [PRs]). Median duration of postchemotherapy neutropenia was 36 days (range, 18 to 45). Therapy was well tolerated, and toxicity was mainly hematologic and nondose-limiting. Despite prolonged neutropenia, severe infections were rarely seen, and most patients were managed as outpatients. Twelve patients had nausea and vomiting, two had symptomatic hypomagnesemia, and one patient showed reversible ototoxicity. Because of substantial antileukemic activity and unusual extrahematologic toxicity, CBDCA appears to be an effective second-line agent in the treatment of ANLL and should be considered for upgrading to first-line treatment regimens.

Seventeen patients with myeloproliferative disorders and one patient with chronic myelomonocytic leukemia (CMMoL) were treated with ranimustine++ (MCNU), and the efficacy was evaluated. MCNU was given intravenously by drip infusion at an usual dose of 100 approximately 150 mg with intervals arranged according to the counts of peripheral blood cells. A complete remission was achieved in all 10 patients with chronic myelogenous leukemia (CML) in chronic phase. In three of patients with polycythemia vera (PV) the excellent effects were obtained, and the other 2 cases showed moderate effect. An excellent effect was obtained in both 2 patients with essential thrombocythemia (ET). A patient with CMMoL revealed partial remission. The overall efficacy rate was 100%. The cases with CML needed more long term and much more dose of the drug in order to get remission compared with PV and ET. After remission in both PV and ET, well controlled states were maintained for a relatively long period with no additional administration. In CMMoL, MCNU combined with 6-mercaptopurine also showed remarkable anti-tumor effects. It suggests that MCNU may be one of the useful drugs for the treatment of CMMoL. The side effects observed with MCNU were a slight degree of nausea and vomiting (28%), however they showed no trouble on carrying out the therapy.

Pentostatin, a novel inhibitor of adenosine deaminase, has shown activity in various lymphoid malignancies of both the T and B cell lineage. This agent has unique side effects and in general myelosuppression has been mild. Interferon has both antiviral and antineoplastic properties. This agent has shown activity in hairy cell leukemia, chronic granulocytic leukemia, low grade lymphoma, and myeloma. Side effects from interferon are in general dissimilar to those that have been seen with pentostatin and in particular myelosuppression has not been a major toxicity with low doses of interferon. This current trial explored the combination of pentostatin and interferon in hematologic malignancies. Fifteen patients were enrolled in this phase I trial at a fixed dose of pentostatin of 4 mg/m2 biweekly and interferon at doses of 0.5, 1, 2, or 4 million units/m2 of interferon. At the first three dose levels of interferon nausea and vomiting were the predominant toxicity and appeared to worsen with time on study. Fatigue also was seen at the lowest level of interferon and was severe enough to cause two individuals to discontinue the study medications. At higher dose levels of interferon, myelosuppression, nausea and vomiting, and fatigue were the predominant toxicities. One patient with hairy cell leukemia had a complete response and a second patient with T cell cutaneous lymphoma had a partial response which lasted for 6 to 7 weeks. The maximum tolerated dose of interferon with pentostatin in this patient population was four million units/m2.
