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.

A 26-year-old male with chronic myelogenous leukemia in lymphoid blast crisis received a bone marrow transplant (BMT) from a phenotypically identical, mixed lymphocyte reaction (MLR)-weakly positive unrelated male volunteer donor. The volunteer was obtained from the Tokai Marrow Donor Bank (TMDB), which was established in Japan in 1989. This donor was selected from volunteer donors who were identical with our patient at the HLA-A,B loci, followed by matching at HLA-DQ, DR loci. On MLR testing, the donor's cells showed no response, but the patient's cells showed a low response to the donor's cells (relative response index 0.29). The patient showed rapid hemopoietic engraftment. He developed acute graft-versus-host disease (GVHD) with vesicle formation on palms and soles and mild liver damage, which were successfully treated with intravenous prednisolone 1 mg/kg per day. Although he also suffered from interstitial pneumonitis on day 64 and localized varicella-zoster infection on day 87, and has suffered from moderate stomatitis and dry skin characteristic of chronic GVHD, he is currently 22 months post-transplant with hematological remission and has a normal daily social life.

The regimen-related toxicity (RRT) of a busulfan (16 mg/kg) and cyclophosphamide (120 mg/kg) conditioning regimen (BuCy) was evaluated in 70 consecutive patients undergoing allogeneic bone marrow transplantation for hematologic malignancies. Patients were given toxicity gradings retrospectively in each of eight organ systems (cardiac, bladder, renal, pulmonary, hepatic, CNS, stomatic, and gastrointestinal) according to a recently developed RRT scale. A set of patient, disease, and treatment parameters (age, sex, diagnosis, Eastern Cooperative Oncology Group [ECOG] score, preconditioning liver function tests [LFT], prior chemotherapy exposure, disease status, graft-versus-host disease [GVHD] prophylaxis, antimicrobial agent use, hematologic recovery, and severity of acute GVHD) was statistically analyzed to determine significant predictors of RRT. The most common significant organ toxicities were stomatic (87% of patients; 63% grades II to IV) and hepatic (83% of patients; 44% grades II to IV). Renal and gastrointestinal toxicities were not uncommon (35% and 27%, respectively) but were rarely serious (9% and 1% grades II to IV, respectively). Twelve patients developed grade III toxicities of the following systems: hepatic (seven), pulmonary (two), bladder (two), and CNS (one). Females had more frequent stomatitis (P = .04) and hepatic RRT (P = .004). Patients receiving methotrexate in their GVHD prophylactic regimen experienced more grade II to IV stomatitis (P = .04) and hepatic RRT (P = .04). The use of amphotericin B (P = .01) or prolonged antibiotic courses (P = .04) was associated with more grades II to IV hepatic RRT. In a multivariate analysis, only amphotericin B administration predicted grades II to IV hepatic RRT (P = .01). The incidence of acute GVHD was 49%, with 31% having grades II to IV GVHD. The estimated 2-year event-free survival (EFS) for the entire study group was 44%. The estimated 2-year EFS was 63% for standard-risk patients (acute leukemia in first remission and chronic myelogenous leukemia [CML] in first stable phase) and 24% for all others (high-risk patients). High-risk patients were at increased risk of disease recurrence and RRT. BuCy is an efficacious bone marrow transplant conditioning regimen for standard-risk patients with leukemia but has significant associated hepatic RRT.

Diaziquone (AZQ) and etoposide (VP-16) were administered as simultaneous 5-day continuous infusions to 27 patients with acute leukemia (22 with acute myeloid leukemia (AML), three with chronic myeloid leukemia in blast crisis (CML-B), and two with acute lymphocytic leukemia) at four different doses in a phase I trial. Gastrointestinal toxicity, primarily stomatitis, was dose limiting, occurring in six of 10 patients at the highest dose level. Diarrhea was the only other grade 3 toxicity noted (three of 10 at the highest dose level). The duration of bone marrow aplasia was excessive at the highest dose (median 48 days to granulocytes greater than 500/mm3, range 33-67) but acceptable (31 days) at the maximum tolerated dose: AZQ 28 mg/m2/day x 5 days, VP-16 150 mg/m2/day x 5 days. Complete remissions were seen in seven patients (six AML, one CML-B) and a partial remission in one patient with AML. The median duration of unmaintained complete remission was 3 months (range 1.5-26+).

The Southeastern Cancer Study Group conducted a phase I-II trial of sequentially administered 5-azacitidine and amsacrine in patients with refractory adult acute leukemia from September 1980 to March 1983. The 5-azacitidine was administered by continuous iv infusion on Days 1-4 at doses ranging from 112 to 200 mg/m2/day, while amsacrine was given at doses ranging from 75 to 150 mg/m2/day on Days 5-8. The doses of 5-azacitidine and amsacrine were alternately escalated through six dose levels during the phase I portion of the trial. Of 128 patients entered, 102 (80%) were evaluable for response. Remission was achieved in 13 of 80 evaluable patients with acute myeloid leukemia, in one of 12 evaluable patients with acute lymphoid leukemia, and in none of 11 patients with blastic transformation of chronic granulocytic leukemia. Three remissions occurred in patients with acute myeloid leukemia who were refractory to initial induction chemotherapy with cytarabine and anthracycline combination chemotherapy. Remissions were relatively durable, lasting a median of 28 weeks in the 13 patients with refractory acute myeloid leukemia (range, 14-54 weeks). Toxic effects included universal severe myelosuppression, hyperbilirubinemia at a frequency and severity similar to those seen with amsacrine used as a single agent, moderately severe stomatitis and diarrhea, three incidents of amsacrine-related cardiac dysrhythmia, and a single case of probable drug-related cardiomyopathy. This combination has activity in the treatment of myeloid leukemia, which is primarily resistant to cytarabine and anthracyclines, and could have a role in primary management.

A new doxorubicin analogue, epirubicin (EPI), has been evaluated in 11 institutions throughout Japan in a phase II study in patients with acute leukemia. A total of 41 patients were entered into this study between January 1983 and July 1985, and 34 were considered evaluable. Two patients were added for evaluation of toxicity. There were 25 males and 9 females with a median age of 43 years. Of the 34 evaluable patients, 24 had previously been treated with intensive combination chemotherapy, 21 with anthracyclines. The remaining ten were previously untreated patients. Underlying diseases were acute lymphocytic leukemia (ALL) in 15, acute non-lymphocytic leukemia (ANLL) in 17 and blastic crisis of chronic myelogenous leukemia (CML/BC) in 2. EPI was administered intravenously in two schedules, a high-dose regimen consisting of 24 to 60 mg/m2/day for 3 to 5 days and a low-dose regimen involving 11-17 mg/m2/day for 5 to 8 days. Responses were obtained in 5 (33.3%) of 15 patients with ALL, 3 of these attaining complete remission, 2 (11.8%) of 17 patients with ANLL and one (50.0%) of 2 patients with CML/BC. Out of the 21 patients who had received previous anthracyclines, 4 (19.1%) attained responses. Also, responses were obtained in 23.5% with the higher doses as well as 24% with the lower doses. The remission duration of responders was 1, 1, 3, 3, 3, 16+, 17 and 26 weeks, respectively. The major non-hematologic toxicity was stomatitis which occurred in 15 patients, in 11 of whom the symptoms were severe (Grade 3 or 4). This stomatitis was thought to be the dose limiting factor. On the basis of the above observations, we concluded that EPI was active against acute leukemia, especially ALL. Stomatitis was considered to be the dose-limiting factor, especially in the high-dose regimen. Toxicity was tolerable in the low-dose regimen.

VP-16 was used to treat newly diagnosed elderly (greater than or equal to 65 yr) patients with acute nonlymphocytic leukemia (ANLL) and patients with blast crisis of chronic granulocytic leukemia (BI-CGL). Our pilot study indicated that VP-16 160 mg/m2 intravenously daily for 5 days was well tolerated and suggested a direct dose-response correlation. Thirty additional ANLL patients and 11 CGL patients were studied. Among 26 evaluable ANLL patients, we observed ten responses (38%) (seven complete remission and three partial remission), but none of 11 patients with CGL in blast crisis had meaningful responses. In patients who responded to treatment, myelosuppression was always reversed by day 25. Stomatitis was the major nonhematologic toxicity and appeared more severe with advancing age. We conclude that VP-16 is active against ANLL and is well tolerated at doses higher than have been previously described. It remains to be shown that the present schedule is superior to the intermittent high-dose or continuous low-dose infusion schedules, which have been recently described.

Amsacrine and high-dose cytarabine (HiDAc), when administered as single agents, are effective treatment of acute leukemia. When used in combination, a high remission rate is also possible. We treated 47 patients with acute myelogenous leukemia (AML), acute lymphoblastic leukemia (ALL), and blastic phase of chronic myelogenous leukemia (CML) with a combination of amsacrine and HiDAc. The patients received amsacrine 200 mg/m2 daily for three days and, concurrently, HiDAc 3 g/m2 over three hours once daily for five days. Of 20 evaluable patients with AML in relapse, there were 12 remissions; of seven additional patients with primary refractory AML, there were two remissions, and of 12 patients with ALL in relapse, there were eight remissions. The three patients with blastic phase CML and the three patients with biphenotypic leukemia did not respond. Nausea, vomiting, stomatitis, hepatic dysfunction, and diarrhea were common, but cutaneous, conjunctival, and significant cerebellar and cerebral side effects were absent. We conclude that this regimen is highly effective therapy for AML and ALL and is also safe, eliminating the major toxicities encountered with HiDAc.

Mitoxantrone was evaluated in a multi-institution trial to define the effective dose for treating acute leukemia, to evaluate its toxicity, and to assess the induction rates for the different types of acute leukemia. Fifty-seven patients have been treated. Of the 24 patients receiving mitoxantrone (10 mg/m2/day X 5), one of nine with acute nonlymphoblastic leukemia (ANLL) in relapse, one of five with acute lymphoblastic leukemia in relapse, and one of seven with blastic chronic myelogenous leukemia achieved remission. At a dose of 12 mg/m2/day X 5, seven of 16 patients with ANLL in relapse, none of six with acute lymphoblastic leukemia in relapse, and one of five with blastic chronic myelogenous leukemia achieved remission. At both dose levels, there was no response in patients who had failed to achieve a prior remission. Toxic effects included nausea/vomiting, stomatitis, and hepatic dysfunction. Nine of the 57 patients treated experienced cardiac events but cardiac toxicity seemed clinically significant in only three. We conclude that mitoxantrone, at a dose of 12 mg/m2/day X 5, is effective therapy for ANLL. Trials combining mitoxantrone with other agents are needed.

The toxic effects of high-dose busulfan (16 mg/kg) and cyclophosphamide (200 mg/kg) with autologous or syngeneic bone marrow rescue were evaluated in 19 patients (11 with acute myelocytic leukemia, one with acute lymphocytic leukemia, one with acute myelofibrosis, two with chronic myelocytic leukemia, one with Hodgkin's disease, and three with non-Hodgkin's lymphoma). Their mean age was 26 years (range, 6-50); nine patients had syngeneic and ten had autologous bone marrow rescue (six of whom had in vitro bone marrow incubation with 4-hydroperoxycyclophosphamide). Severe myelosuppression was expected and was seen in all patients; leukocyte and platelet count recovery occurred at a median of 19 days (range, 11-59) and 30 days (range, 20-89), respectively. Nausea, vomiting, and diarrhea were frequent but readily managed with vigorous medical therapy. Stomatitis was severe in 14 patients. Skin, renal, cardiac, pulmonary, and CNS complications directly attributable to drug-related toxic effects were transient and non-life-threatening. Hepatic function abnormalities were common but tended to be transient. Most patients tolerated high-dose busulfan and cyclophosphamide with manageable side effects. Hepatic veno-occlusive disease was fatal in two patients, while diffuse interstitial pneumonitis with disseminated herpes virus infection was fatal in three patients with lymphoma. All patients treated in relapse or without previous therapy had a complete tumor response. Further studies with this regimen should be pursued.
