Abstract Background: Patients aged 15 to 39 years old constitute the Adolescent Young Adult (AYA) population. In the US, leukemias represent ~6% of all cancers in this population with the incidence of Acute Lymphoblastic Leukemia (ALL) gradually decreasing with age as the incidence of acute and chronic myeloid leukemias (AML, CML, respectively) increase; ALL occurs at approximately twice the rate of AML in 15- to 19-year olds. Further studies are needed to define the unique features of leukemia in AYA patients, and to better assess and optimize treatment regimens. Marqibo®, vincristine sulfate liposome injection, uses a novel sphingomyelin and cholesterol nanoparticle that facilitates vincristine dose intensification without exacerbation of its toxicity, i.e., it has a wider therapeutic index than standard formulation vincristine. This formulation has also been shown to enhance the penetration and concentration of vincristine into tumors, and prolong plasma circulation time in non-clinical experiments. Marqibo is approved in the US for the treatment of adult patients with Philadelphia chromosome negative (Ph-) ALL in second or greater relapse, whose disease has progressed following two or more previous lines of therapy. We performed a retrospective analysis of data from the Phase 2 RALLY clinical trial (n=65) to examine the effects of Marqibo in the subgroup of the AYA population. The Phase 2 study results of the entire study demonstrated that treatment with single-agent Marqibo resulted in an Overall Response Rate (ORR) of 35%, with 20% of patients achieving a Complete Response (CR) or CR with Incomplete Blood Count Recovery (CRi) (O'Brien, S., 2012 J Clin Oncol). Methods: Data from the RALLY Phase 2 study of Marqibo were analyzed retrospectively to examine only the relapsed or refractory Ph- ALL patients 39 years of age and younger (n=44). In this study, Marqibo (2.25mg/m2) was administered via IV over 60 minutes without dose capping, once per week until response, progression, toxicity or hematopoietic transplant. Results: The median age of the 44 patients was 27 (range: 19-39), 57% were male, 82% had B-cell ALL and 18% had T-cell ALL. 84% had ECOG performance status of 0 or 1. The number of previous treatments ranged from 2-6. 41% had 2 prior lines of treatment, 41% had 3 prior lines of treatment, 16% had 4 prior lines of treatment and 2% had 6 prior lines of treatment. In addition, 59% of patients had previously received a hematopoietic cell transplant. The ORR in the AYA population was 39%, with 25% of patients achieving a CR or CRi. Overall, the safety profile of Marqibo was similar to that in the older adult population, with 35 (79.5%) patients having a treatment-related adverse event, of any grade, on study. The most common treatment-related adverse events, of any grade, in the AYA population were constipation (34%) and peripheral neuropathy (32%). Conclusions: Marqibo (vincristine sulfate liposome injection) was shown to have clinical benefit in AYA patients with relapsed or refractory Ph- ALL with similar safety and efficacy profiles compared to the entire adult population (range: 19-83).

Pivotal Phase

Purpose Relapsed adult acute lymphoblastic leukemia (ALL) is associated with high reinduction mortality, chemotherapy resistance, and rapid progression leading to death. Vincristine sulfate liposome injection (VSLI), sphingomyelin and cholesterol nanoparticle vincristine (VCR), facilitates VCR dose-intensification and densification plus enhances target tissue delivery. We evaluated high-dose VSLI monotherapy in adults with Philadelphia chromosome (Ph) –negative ALL that was multiply relapsed, relapsed and refractory to reinduction, and/or relapsed after hematopoietic cell transplantation (HCT). Patients and Methods Sixty-five adults with Ph-negative ALL in second or greater relapse or whose disease had progressed following two or more leukemia therapies were treated in this pivotal phase II, multinational trial. Intravenous VSLI 2.25 mg/m2, without dose capping, was administered once per week until response, progression, toxicity, or pursuit of HCT. The primary end point was achievement of complete response (CR) or CR with incomplete hematologic recovery (CRi). Results The CR/CRi rate was 20% and overall response rate was 35%. VSLI monotherapy was effective as third-, fourth-, and fifth-line therapy and in patients refractory to other single- and multiagent reinduction therapies. Median CR/CRi duration was 23 weeks (range, 5 to 66 weeks); 12 patients bridged to a post-VSLI HCT, and five patients were long-term survivors. VSLI was generally well tolerated and associated with a low 30-day mortality rate (12%). Conclusion High-dose VSLI monotherapy resulted in meaningful clinical outcomes including durable responses and bridging to HCT in advanced ALL settings. The toxicity profile of VSLI was predictable, manageable, and comparable to standard VCR despite the delivery of large, normally unachievable, individual and cumulative doses of VCR.

The NCCN Guidelines for Acute Lymphoblastic Leukemia (ALL) focus on the classification of ALL subtypes based on immunophenotype and cytogenetic/molecular markers; risk assessment and stratification for risk-adapted therapy; treatment strategies for Philadelphia chromosome (Ph)-positive and Ph-negative ALL for both adolescent and young adult and adult patients; and supportive care considerations. Given the complexity of ALL treatment regimens and the required supportive care measures, the NCCN ALL Panel recommends that patients be treated at a specialized cancer center with expertise in the management of ALL This portion of the Guidelines focuses on the management of Ph-positive and Ph-negative ALL in adolescents and young adults, and management in relapsed settings.

Measurable Residual Disease

Abstract The presence of measurable residual disease (MRD) in acute lymphoblastic leukemia (ALL) confers a poor prognosis. CD19-targeted immunotherapy is effective against MRD but is logistically challenging, potentially toxic, and not applicable to T-cell ALL. We thus hypothesized that inhibition of PD-1 with pembrolizumab could also be effective for MRD, but without lineage restriction. The primary objective of this phase 2 study was to evaluate the efficacy of pembrolizumab in patients with ALL and MRD. Key eligibility criteria included adults with B- or T-cell ALL and MRD detectable by multiparameter flow cytometry or quantitative polymerase chain reaction from bone marrow aspirate (BMA) despite chemotherapy (plus ABL kinase inhibitor if Philadelphia chromosome positive). Pembrolizumab 200 mg IV was given every 3 weeks. Response was assessed by BMA using methods that previously detected MRD. The primary end point was complete MRD response rate. We stopped enrollment early; only 1 of 12 (8%) experienced a complete MRD response, which lasted 3 weeks. Interestingly, this patient had previously received hematopoietic cell transplantation and CD19-targeted chimeric antigen receptor–modified T-cell therapy and was the only patient to experience an immune-related adverse event from pembrolizumab (grade 3 Stevens-Johnson syndrome). Median overall survival from enrollment was 12.7 months. In summary, pembrolizumab had minimal activity against MRD but was generally well tolerated. These data can be compared with ongoing anti-PD-1 combination studies in ALL, and they further establish the role of trials specifically for patients with MRD. This trial was registered at www.clinicaltrials.gov as #NCT02767934.
