Directions

Summary

Our research is focused on Acute lymphoblastic Leukemia (ALL) disease, including B-cell precursor and T-precursor ALL. We want to resolve questions that require a full range of research from from basic to clinical. We aim to provide the physician with new tools, by using basic research data that will have an impact on healthcare, in order to improve survival rates in patients with this type of leukaemia.

Research

Acute Lymphoblastic Leukemia is still a non-curable neoplasia mainly in adult patients. The survival rates for ALL are much lower in adults than in children. The reasons for this survival difference lie largely in the higher frequency of poor prognosis subtypes of ALL in adults and a poorer tolerance of the treatment as age increases. Except for selected subgroups (i.e., Ph+ ALL), the current therapeutic protocols for ALL do not take into account the differences in the molecular background of the disease, and few new alternative therapies are only available in refractory or resistant ALL. Therefore, if we want to improve the survival of patients with ALL we first need to obtain detailed and relevant molecular information to enable doctors to accurately define the risk and decide on the treatment. Secondly, we need to have specific therapeutic alternatives available to apply to these new oncogenetic ALL subgroups.

Main Research Lines:

The current research of the group at the IJC Institute can be divided in two main areas:

1: Clinical research: Design and analysis of the results of the Spanish treatment protocols on adult ALL in the setting of the Spanish PETHEMA group (Programa Español de Tratamientos en Hematología).

2. Biologic and translational research

The ALL Group is currently evaluating the frequency and prognostic significance of new genetic markers in B- and T- lineage ALL. The results of this study, which are in line with the results found by other ALL working groups, will be applied in the new therapeutic protocols in ALL of the PETHEMA group.

In addition, we want to assess the anti-leukemic effect of the available drugs that specifically target candidate genes in an in vivo model. We also want to check if copy number alterations (CNAs) identified in other blood neoplasias such as; Acute Myeloblastic Leukaemia (AML), Non-Hodgkin Lymphoma (NHL) and Chronic Myeloid Leukaemia (CLL), or in solid cancers such as Melanoma and Breast Cancer, could also have an impact on ALL. We expect that the results obtained, will be used to re-classify ALL patients into different oncogenetic subgroups according to the predicted treatment response and the specific target therapy to be applied.

The identification of clonal heterogeneity in ALL at the time of diagnosis has introduced a high order of complexity to the disease. It is this clonal heterogeneity that is responsible for patient’s relapses, in which treatment has failed. Future projects in the group will be focused on the characterization of leukemic cells resistant to treatment using a genetic and functional approach.

Deletion 6q Drives T-cell Leukemia Progression by Ribosome Modulation.

Deletion of chromosome 6q is a well-recognized abnormality found in poor-prognosis T-cell acute lymphoblastic leukemia (T-ALL). Using integrated genomic approaches, we identified two candidate haploinsufficient genes contiguous at 6q14,

Frequency and clinical impact of CDKN2A/ARF/CDKN2B gene deletions as assessed by in-depth genetic analyses in adult T cell acute lymphoblastic leukemia.

J Hematol Oncol 24 Jul 2018, 11 (1) 96. Epub 24 Jul 2018
Recurrent deletions of the CDKN2A/ARF/CDKN2B genes encoded at chromosome 9p21 have been described in both pediatric and adult acute lymphoblastic leukemia (ALL), but their prognostic value remains controversial, with limited data on adult T-ALL. Here, we investigated the presence of homozygous and heterozygous deletions of the CDKN2A/ARF and CDKN2B genes in 64 adult T-ALL patients enrolled in two consecutive trials from the Spanish PETHEMA group. Alterations in CDKN2A/ARF/CDKN2B were detected in 35/64 patients (55%). Most of them consisted of 9p21 losses involving homozygous deletions of the CDKNA/ARF gene (26/64), as confirmed by single nucleotide polymorphism (SNP) arrays and interphase fluorescence in situ hybridization (iFISH). Deletions involving the CDKN2A/ARF/CDKN2B locus correlated with a higher frequency of cortical T cell phenotype and a better clearance of minimal residual disease (MRD) after induction therapy. Moreover, the combination of an altered copy-number-value (CNV) involving the CDKN2A/ARF/CDKN2B gene locus and undetectable MRD (≤ 0.01%) values allowed the identification of a subset of T-ALL with better overall survival in the absence of hematopoietic stem cell transplantation.

Preclinical Development of a Bispecific Antibody that Safely and Effectively Targets CD19 and CD47 for the Treatment of B-Cell Lymphoma and Leukemia.

Mol. Cancer Ther. Ago 2018, 17 (8) 1739-1751. Epub 9 Mai 2018
CD47, an ubiquitously expressed innate immune checkpoint receptor that serves as a universal "don't eat me" signal of phagocytosis, is often upregulated by hematologic and solid cancers to evade immune surveillance. Development of CD47-targeted modalities is hindered by the ubiquitous expression of the target, often leading to rapid drug elimination and hemotoxicity including anemia. To overcome such liabilities, we have developed a fully human bispecific antibody, NI-1701, designed to coengage CD47 and CD19 selectively on B cells. NI-1701 demonstrates favorable elimination kinetics with no deleterious effects seen on hematologic parameters following single or multiple administrations to nonhuman primates. Potent
