On January 8, 2020 A study at The University of Texas MD Anderson Cancer Center reported a potential new approach to treating two of the most common subtypes of lymphoma through manipulation of molecular programs controlled by the cAMP-response element binding protein (CREBBP) (Press release, MD Anderson, JAN 8, 2020, View Source [SID1234553265]). Mutations of CREBBP are frequently found in follicular lymphoma and diffuse large B-cell lymphomas (DLBCL), and allow malignant cells to hide from the immune system.

Study results were published in the Jan. 8 online issue of Cancer Discovery. Co-lead investigators, Michael Green, Ph.D., assistant professor of Lymphoma & Myeloma at MD Anderson and Ari Melnick, M.D., of Weill Cornell Medical School, reported on how inhibition of a protein called histone deacetylase 3 (HDAC3) restores immune programs lost as a result of CREBBP mutations, paving the way for potential immunotherapy approaches for common forms of non-Hodgkin lymphoma.

CREBBP is the second most frequently mutated chromatin-modifying gene in both follicular lymphoma and DLBCL. It encodes a protein that alters the activity of genes by modifying the histone proteins around which DNA is wrapped.

"CREBBP mutations are highly recurrent in B-cell lymphomas and either inactivate its histone acetyltransferase (HAT) domain or truncate the protein," said Green." We showed that these two classes of mutations yield different degrees of disruption of the epigenome, with HAT mutations being more severe and associated with inferior clinical outcome."

Through CRISPR/Cas9 gene editing of cell lines and using mouse models, the research team also showed that HDAC3 selective inhibitors reverse aberrant epigenetic programming caused by CREBBP resulting in growth inhibition of lymphoma cells and restoration of immune surveillance.

"Our study characterized the molecular consequences of CREBBP mutations and identified key cellular pathways silenced as a result of unopposed HDAC3 activity," said Green. "We demonstrated how inhibition of HDAC3 restores these pathways, suppressing growth and most critically enabling T cells to recognize and kill lymphoma cells."

HDAC3 inhibitors appear to affect expression of major histocompatibility molecular class II (MHC class II), molecules, which are antigen presentation proteins crucial for initiating adaptive immune responses.

"The frequency of MHC class II loss in DLBCL exceeds the frequency of CREBBP mutations in this disease through unknown mechanisms," said Green. "The ability of HDAC3 inhibition to induce MHC class II expression may have potentially broad implications for immunotherapy. We believe that inhibition of HDAC3 represents a novel mechanism-based immune-epigenetic therapy for CREBBP- mutant lymphomas."

On January 8, 2020 Adaptive Biotechnologies Corporation (Nasdaq: ADPT), a commercial stage biotechnology company that aims to translate the genetics of the adaptive immune system into clinical products to diagnose and treat disease, reported that Palmetto GBA, a Medicare Administrative Contractor (MAC) that assesses diagnostic technologies through its MolDX program, has expanded coverage of the clonoSEQ Assay to include monitoring minimal residual disease (MRD) in Medicare patients with chronic lymphocytic leukemia (CLL) (Press release, Adaptive Biotechnologies, JAN 8, 2020, View Source [SID1234552838]). This adds to existing Medicare coverage in B-cell acute lymphoblastic leukemia (ALL) and multiple myeloma, which was established in January 2019. Medicare coverage for clonoSEQ is aligned with clinical practice guidelines in covered disease states which support assessing MRD at multiple time points throughout therapy to monitor treatment response and help predict patient outcomes. This expanded coverage policy is effective immediately and continues the positive momentum for clonoSEQ with over 175M lives covered to date.

"Patients with CLL who achieve undetectable MRD have better outcomes than those with detectable MRD," said Javier Pinilla-Ibarz, M.D., Ph.D., Senior Member and Head of the Lymphoma program in the Department of Malignant Hematology at Moffit Cancer Center. "As newer therapies emerge for CLL that can help patients achieve very deep remissions, assessment of MRD can help guide clinical care by determining a patient’s response to therapy and informing that patient’s prognosis."

MRD refers to the remaining number of cancer cells that may be present in a patient’s body during and after treatment and that may eventually lead to recurrence of the disease. MRD testing is performed as a series of tests throughout a patient’s cancer journey to monitor for remission, detect relapse, determine response to treatment and inform care. Controlled trials have shown that even the smallest amounts of residual disease significantly predict a patient’s long-term clinical outcomes.

"Data are mounting to support the clinical benefits of MRD measurement in lymphomas and leukemias, including CLL, to help assess a patient’s prognosis, measure response to therapy and inform treatment decisions," said Lance Baldo, chief medical officer, Adaptive Biotechnologies. "The Medicare coverage expansion validates this growing body of evidence and provides patients living with CLL greater access to highly sensitive, standardized MRD testing."

clonoSEQ is the only test authorized by the U.S. Food and Drug Administration (FDA) to detect and monitor minimal residual disease in any lymphoid cancer. At the 2019 American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting, an unprecedented amount of data was presented demonstrating the clinical significance of MRD in blood cancers and further validating it as one of the strongest predictors of patient outcomes.

About the clonoSEQ Assay

The clonoSEQ Assay was granted de novo designation and marketing authorization by FDA for the detection and monitoring of minimal residual disease (MRD) in patients with multiple myeloma (MM) and B-cell acute lymphoblastic leukemia (ALL) using DNA from bone marrow samples. clonoSEQ is the first and only FDA-authorized in vitro diagnostic assay for MRD testing. It is also the first clinical diagnostic powered by immunosequencing to receive FDA clearance. clonoSEQ leverages Adaptive’s proprietary immunosequencing platform to identify and quantify specific DNA sequences found in malignant cells, allowing clinicians to assess and monitor MRD during and after treatment. The assay provides standardized, accurate and sensitive measurement of MRD that allows physicians to predict patient outcomes, assess response to therapy over time, monitor patients during remission and detect potential relapse. Clinical practice guidelines in hematological malignancies recognize that MRD status is a reliable indicator of clinical outcomes and response to therapy, and clinical outcomes are strongly associated with MRD levels measured by the clonoSEQ Assay in patients diagnosed with ALL and MM. More than 175 million people in the US now have access to clonoSEQ through Medicare and private payor coverage.

clonoSEQ is a single-site assay performed at Adaptive Biotechnologies. It is also available as a CLIA-regulated laboratory developed test (LDT) service for use in other lymphoid cancers.

On January 8, 2020 SELLAS Life Sciences Group, Inc. (Nasdaq: SLS) ("SELLAS" or the "Company"), a late-stage clinical biopharmaceutical company focused on the development of novel cancer immunotherapies for a broad range of cancer indications, reported that it has started patient screening for its pivotal Phase 3 REGAL clinical trial of its lead clinical candidate, galinpepimut-S (GPS), in patients with acute myeloid leukemia (AML) who have achieved complete remission after second-line anti-leukemic therapy (CR2) (Press release, Sellas Life Sciences, JAN 8, 2020, View Source [SID1234552855]). The study is expected to enroll approximately 116 patients across approximately 50 clinical sites in the U.S. and Europe. GPS was previously granted Fast Track designation and orphan drug designation in AML by the U.S. Food and Drug Administration (FDA) and orphan drug designation by the European Medicines Agency (EMA).

"The commencement of our Phase 3 clinical trial marks an important milestone for SELLAS, and reflects our continued commitment to developing GPS as a potential first-in-class WT1-targeting cancer vaccine for patients with AML. We are indeed excited that patient screening is underway for our REGAL study," said Angelos Stergiou, MD, ScD h.c., President and Chief Executive Officer of SELLAS. "In previous Phase 2 studies in patients with AML, GPS has demonstrated a clinically meaningful and statistically significant prolonging of survival by delaying or preventing recurrence in patients in complete remission, who often are at very high risk of relapse. Of particular note, our Phase 2 AML CR2 study, which is the indication for our Phase 3 study, showed a 10.9 months survival benefit with a p-value of 0.0175. We remain focused on expeditiously enrolling our Phase 3 study. The results from the REGAL study, if positive, will be used as the basis for a Biologics License Application (BLA) submission to the FDA."

The REGAL study is a 1:1 randomized, open-label study comparing GPS monotherapy in the maintenance setting to investigators’ choice best available treatment in AML patients who have achieved hematologic complete remission, with or without thrombocytopenia (CR2/CR2p), after second-line antileukemic therapy and who are deemed ineligible for or unable to undergo allogeneic stem-cell transplantation. The primary endpoint is the overall survival (OS) from the time of study entry. Secondary endpoints include leukemia-free survival, antigen-specific T-cell immune response dynamics, measurable residual disease by multigene array, and assessments of AML clonal evolution and inflammasome molecular signatures in the tumor microenvironment in bone marrow biopsy samples. The Company anticipates interim analysis for safety and futility in the fourth quarter of 2021.

In a previous Phase 2a study in AML patients in the CR2 setting, GPS demonstrated a clinically meaningful and statistically significant median OS of 16.3 months in AML CR2 patients vs. 5.4 months in contemporaneously assessed unvaccinated patients (p = 0.0175). Treatment-related adverse events were primarily comprised of Grade 1 or 2 local injection site reactions and one Grade 3 (transient leukopenia) adverse event. A second previous Phase 2 study of GPS in AML patients who achieved first complete remission (CR1) also met its primary endpoint with an OS rate at 3 years from first vaccination of 47%.
