Abstract Relapse after autologous bone marrow transplantation for chronic myelogenous leukemia (CML) can be due either to the persistence of leukemia cells in systemic tissues following preparative therapy, or due to the persistence of leukemia cells in the autologous marrow used to restore marrow function after intensive therapy. To help distinguish between these two possible causes of relapse, we used safety-modified retroviruses, which contain the bacterial resistance gene NEO, to mark autologous marrow cells that had been collected from patients early in the phase of hematopoietic recovery after in vivo chemotherapy. The cells were then subjected to ex vivo CD34 selection following collection and 30% of the bone marrow were exposed to a safety-modified virus. This marrow was infused after delivery of systemic therapy, which consisted of total body irradiation (1,020 cGy), cyclophosphamide (120 mg/kg), and VP-16 (750 mg/m2). RT PCR assays specific for the bacterial NEO mRNA, which was coded for by the virus, and the bcr-abl mRNA showed that in two evaluable CML patients transplanted with marked cells, sufficient numbers of leukemia cells remained in the infused marrow to contribute to systemic relapse. In addition, both normal and leukemic cells positive for the retroviral transgenome persisted in the systemic circulation of the patients for at least 280 days posttransplant showing that the infused marrow was responsible for the return of hematopoiesis following the preparative therapy. This observation shows that it is possible to use a replication-incompetent safety-modified retrovirus in order to introduce DNA sequences into the hematopoietic cells of patients undergoing autologous bone marrow transplantation. Moreover, this data suggested that additional fractionation procedures will be necessary to reduce the probability of relapse after bone marrow transplantation in at least the advanced stages of the disease in CML patients undergoing autologous bone marrow transplantation procedures.

BCR-ABL antisense oligodeoxynucleotides (ODN) have provided evidence of antileukemia effect when tested in vitro against Philadelphia-positive (Ph-pos) cells and in vivo when injected into leukemic mice. On the basis of the results obtained in vitro at diagnosis, eight patients with chronic myelogenous leukemia (CML) were selected and submitted to autologous bone marrow transplantation (ABMT) with bone marrow (BM) cells purged in vitro with junction-specific (J-sp) BCR-ABL antisense ODN at the time of transformation in accelerated phase or during second chronic phase. Mononuclear BM cells were treated in vitro for 24 or 72 hours with 150 μg/mL of antisense ODN yielding a median recovery of 47.6% mononuclear cells, 48.8% CD34+ cells, and 20.3% clonogenic cells. After a conditioning regimen including busulphan and etoposide, the reinfused treated cells allowed engraftment and hematologic reconstitution in all patients. Evaluation of the antileukemic effect by standard cytogenetic analysis and fluorescence in situ hybridization showed a complete karyotypic response in two cases and a minimal or no response in the other six. The patient autografted in second chronic phase died in blast crisis 7 months after ABMT; of the seven patients autografted in transformation, three developed blast crisis 21 to 39 months after reinfusion, one died from unrelated BMT complications 30 months after ABMT, and three are in persistent second chronic phase 14 to 26 months after autograft. The low toxicity of the protocol and the hemopoietic reconstitution observed in all patients make this approach feasible; the marked karyotypic response observed in some patients and the duration of the second chronic phase show that ODN-mediated BM purging and autograft is a promising treatment for this high-risk group of CML.

Sixteen patients with poor-prognosis acute myelogenous leukemia (AML), acute lymphoblastic leukemia (ALL), and non-Hodgkin's lymphoma (NHL) underwent conditioning with busulfan (16 mg/kg) and cyclophosphamide (120 mg/kg) (BUCY-2) plus melphalan (90 or 135 mg/m2) and autologous bone marrow transplantation (AuBMT) in a phase I study. At the melphalan dose of 90 mg/m2, grade greater than or equal to 3 regimen-related toxicity (RRT) was observed in five patients (31%; 95% confidence interval [CI], 11% to 59%), with hepatic (venoocclusive disease [VOD]) and urinary (hemorrhagic cystitis) RRT being the most frequent complications. Further escalation of the melphalan dose to 135 mg/m2 was deemed excessively toxic, as three of five patients had grade greater than or equal to 3 RRT. Following this experience, 21 patients with multiple myeloma (MM) and chronic myelogenous leukemia (CML) were treated with BUCY-2 plus melphalan 90 mg/m2 and AuBMT in separate studies. Three of these patients--all with extensively pretreated MM--had grade greater than or equal to 3 RRT (14%; 95% CI, 3% to 36%); no others had grade greater than or equal to 3 RRT. Therefore, a total of eight of the 37 patients (22%; 95% CI, 10% to 38%) who received BUCY-2 plus melphalan 90 mg/m2 conditioning developed grade greater than or equal to 3 RRT; three of these patients (8%; 95% CI, 3% to 25%) died of RRT. Although limited by the relatively small number of patients, our analysis of the patients receiving this regimen showed that the presence of parameters denoting the lymphoid diagnostic group (ie, ALL, NHL, and MM), more extensive pretreatment, and/or more advanced disease status were associated with a higher incidence of grade greater than or equal to 3 RRT. Response data on the AML, ALL, and NHL patients who received BUCY-2 plus melphalan 90 mg/m2 were analyzed: three patients (all with AML in first or second remission) are leukemia-free at 3.0, 2.8, and 1.4 years after AuBMT. The actuarial 2-year event-free survival in this group is 17% (95% CI, 5% to 54%). Response data on the MM and CML patients will be reported subsequently. BUCY-2 plus melphalan at a dose of 90 mg/m2 before AuBMT produces acceptable toxicity in patients who are not heavily pretreated. A full evaluation of the antineoplastic effects of this regimen requires further study.

Eleven patients with Philadelphia chromosome (Ph1)-positive chronic myelogenous leukemia (CML) in blast crisis (ten patients) or accelerated disease (one patient) were treated with piperazinedione (PIP) and fractionated total body irradiation (TBI) followed by autologous bone marrow transplantation (ABMT). Three patients were transplanted with marrow from which the Ph1 clone had been eradicated by prior intensive chemotherapy. All patients responded with disappearance of blasts in bone marrow and peripheral blood. Six patients achieved a second chronic phase lasting 3 to 14 months (median, 6 months). Two patients had incomplete recovery, and three patients failed to engraft and died from infection. Transplantation with Ph1-negative bone marrow did not improve response duration or survival. Recurrence of blast crisis and incomplete engraftment continue to be the two major problems in this patient group, and more active regimens need to be investigated.
