NEWTON, Mass., May 18, 2017 (GLOBE NEWSWIRE) -- Karyopharm Therapeutics Inc. (Nasdaq:KPTI), a clinical-stage pharmaceutical company, today announced that interim clinical data from the ongoing Phase 2b SADAL study evaluating lead product candidate, selinexor (KPT-330), an oral Selective Inhibitor of Nuclear Export / SINE™ compound, in patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL) will be featured in an oral presentation at the 22nd Congress of the European Hematology Association (EHA) taking place June 22-25, 2017 in Madrid, Spain. “DLBCL is the most common type of non-Hodgkin lymphoma among adults and there remains a high unmet medical need, particularly in the relapsed and refractory setting for patients who are not eligible for stem cell transplant or who relapse afterward,” said Sharon Shacham, PhD, MBA, President and Chief Scientific Officer of Karyopharm.  “Previously reported data from the ongoing Phase 2b SADAL study showed that treatment with single-agent oral selinexor resulted in robust response rates with prolonged durability in patients with heavily pretreated DLBCL, including against both GCB and non-GCB (ABC) subtypes.  We look forward to sharing some further detail from the SADAL study with the medical community at EHA and ICML this year.” In addition, Karyopharm’s Phase 2b SADAL data were also selected for a poster presentation at the 14th International Conference on Malignant Lymphoma (ICML) being held June 14-17, 2017 in Lugano, Switzerland. Details for the Oral Presentation at EHA 2017: Title: Single Agent Oral Selinexor Exhibits Durable Responses in Relapsed/Refractory Diffuse Large B-Cell Lymphoma (DLBCL) of Both GCB and Non-GCB Subtypes: The Phase 2b SADAL Study Presenter: Marie Maerevoet, Institute Jules Bordet, Brussels, Belgium Abstract code: S469 Topic: Aggressive Non-Hodgkin lymphoma – Clinical Session: Aggressive Non-Hodgkin lymphoma – Relapsed/refractory Location: Hall C Date and Time: Saturday, June 24, 2017 from 14:45 - 17:00 CET Details for the Poster Presentation at ICML 2017: Title: A Phase 2b Randomized Study of Single Agent Selinexor in Patients with Relapsed/Refractory Diffuse Large B-Cell Lymphoma (DLBCL) Presenter: Rene-Olivier Casanovas, Hematologie Clinique, CHU Dijon, France Poster #: 193 Location: Marquee Parco Ciani Date and Time: From Wednesday, June 14, 2017 at 12:00 CET through Friday, June 16, 2017 at 18:30 CET Selinexor (KPT-330) is a first-in-class, oral Selective Inhibitor of Nuclear Export / SINE™ compound. Selinexor functions by binding with and inhibiting the nuclear export protein XPO1 (also called CRM1), leading to the accumulation of tumor suppressor proteins in the cell nucleus. This reinitiates and amplifies their tumor suppressor function and is believed to lead to the selective induction of apoptosis in cancer cells, while largely sparing normal cells. To date, over 2,000 patients have been treated with selinexor and it is currently being evaluated in several mid- and later-phase clinical trials across multiple cancer indications, including in multiple myeloma in combination with low-dose dexamethasone (STORM) and backbone therapies (STOMP), and in diffuse large B-cell lymphoma (SADAL), and liposarcoma (SEAL), among others. Karyopharm plans to initiate a pivotal randomized Phase 3 study of selinexor in combination with bortezomib (Velcade®) and low-dose dexamethasone (BOSTON) in patients with multiple myeloma in May 2017. Additional Phase 1, Phase 2 and Phase 3 studies are ongoing or currently planned, including multiple studies in combination with one or more approved therapies in a variety of tumor types to further inform the Company's clinical development priorities for selinexor. Additional clinical trial information for selinexor is available at www.clinicaltrials.gov. Karyopharm Therapeutics Inc. (Nasdaq:KPTI) is a clinical-stage pharmaceutical company focused on the discovery and development of novel first-in-class drugs directed against nuclear transport and related targets for the treatment of cancer and other major diseases. Karyopharm's SINE™ compounds function by binding with and inhibiting the nuclear export protein XPO1 (or CRM1).

Monoclonal gammopathy of renal significance (MGRS) regroups all renal disorders caused by a monoclonal immunoglobulin (MIg) secreted by a nonmalignant B-cell clone. By definition, patients with MGRS do not meet the criteria for overt multiple myeloma/B-cell proliferation, and the hematologic disorder is generally consistent with monoclonal gammopathy of undetermined significance (MGUS). However, MGRS is associated with high morbidity due to the severity of renal and sometimes systemic lesions induced by the MIg. Early recognition is crucial, as suppression of MIg secretion by chemotherapy often improves outcomes. The spectrum of renal diseases in MGRS is wide, including old entities such as AL amyloidosis and newly described lesions, particularly proliferative glomerulonephritis with monoclonal Ig deposits and C3 glomerulopathy with monoclonal gammopathy. Kidney biopsy is indicated in most cases to determine the exact lesion associated with MGRS and evaluate its severity. Diagnosis requires integration of morphologic alterations by light microscopy, immunofluorescence (IF), electron microscopy, and in some cases by IF staining for Ig isotypes, immunoelectron microscopy, and proteomic analysis. Complete hematologic workup with serum and urine protein electrophoresis, immunofixation, and serum-free light-chain assay is required. This review addresses the pathologic and clinical features of MGRS lesions, indications of renal biopsy, and a proposed algorithm for the hematologic workup. © 2015 International Society of Nephrology.

The prognostic value of interim positron emission tomography (PET) interpreted according to visual criteria is a matter of debate in diffuse large B-cell lymphoma (DLBCL). Maximal standardized uptake value reduction (ΔSUVmax) may better predict outcome. To compare the prognostic value of both methods, we analyzed PET done at baseline (PET0) and after 2 (PET2) and 4 (PET4) cycles in 85 patients with high-risk DLBCL enrolled on a prospective multicenter trial. All images were centrally reviewed and interpreted visually according to the International Harmonization Project criteria and by computing ΔSUVmax between PET0 and PET2 (ΔSUVmaxPET0-2) or PET4 (ΔSUVmaxPET0-4). Optimal cutoff to predict progression or death was 66% for ΔSUVmaxPET0-2 and 70% for ΔSUVmaxPET0-4. Outcomes did not differ significantly whether PET2 and PET4 were visually positive or negative. Inversely, ΔSUVmaxPET0-2 analysis (> 66% vs ≤ 66%) identified patients with significantly different 2-year progression-free survival (77% vs 57%; P = .0282) and overall survival (93% vs 60%; P < .0001). ΔSUVmaxPET0-4 analysis (> 70% vs ≤ 70%) seemed even more predictive for 2-year progression-free survival (83 vs 40%; P < .0001) and overall survival (94% vs 50%; P < .0001). ΔSUVmax analysis of sequential interim PET is feasible for highrisk DLBCL and better predicts outcome than visual analysis. The trial was registered at http://clinicaltrials.gov as NCT00498043. © 2011 by The American Society of Hematology.

Purpose: The presence of a bulky tumour at staging in Hodgkin lymphoma (HL) is a predictor of a poor outcome. The total metabolic tumour volume at baseline (TMTV0) computed on PET may improve the evaluation of tumour burden. To explore the clinical usefulness of TMTV0, we compared the prognostic value of TMTV0, tumour bulk and interim PET response in a retrospective single-centre study. Methods: From 2007 to 2010, 59 consecutive patients with a first diagnosis of HL were treated in our institution. PET was done at baseline (PET0) and after two cycles of chemotherapy (PET2), and treatment was not modified according to the PET2 result. TMTV0 was measured with a semiautomatic method using a 41 % SUVmax threshold. SUVmax reduction between PET0 and PET2 (ΔSUVmaxPET0-2) was also computed. Based on ROC analysis, patients with a ΔSUVmaxPET0-2 >71 % were considered good responders and a TMTV0 >225 ml was considered to represent hypermetabolic bulky disease. Results: Median TMTV0 was 117 ml and 17 patients (29 %) had a TMTV0 >225 ml. TMTV0 (>225 ml vs. ≤225 ml) and tumour bulk (<10 cm vs. ≥10 cm) were predictive of 4-year PFS: 42 % vs. 85 % (p=0.001) and 44 % vs. 79 % (p < 0.03), respectively. In multivariate analysis, using ΔSUVmaxPET0-2, TMTV0 and bulky tumour as covariates, only ΔSUVmaxPET0-2 (p=0.0005, RR 6.3) and TMTV0 (p < 0.006, RR 4.4) remained independent predictors of PFS. Three prognosis groups were thus identified: ΔSUVmaxPET0-2 >71 % and TMTV0 ≤225 ml (n=37, 63 %), ΔSUVmaxPET0-2=<71 % or TMTV0 >225 ml (n=17, 29 %), and ΔSUVmaxPET0-2=<71 % and TMTV0 >225 ml (n=5, 8 %). In these three groups the 4-year PFS rates were 92 %, 49 %, and 20 % (p < 0.0001), respectively. Conclusion: TMTV0 is more relevant than tumour bulk for predicting the outcome in patients with HL, and adds a significant prognostic insight to interim PET response assessment. The combination of TMTV0 and ΔSUVmaxPET0-2 made it possible to identify three subsets of HL patients with different outcomes. This may guide clinicians in their choice of therapeutic strategy. © 2014 Springer-Verlag.

Mutations in the Bcr-Abl kinase domain may cause, or contribute to, resistance to tyrosine kinase inhibitors (TKIs) in chronic myeloid leukemia patients. Recommendations aimed to rationalize the use of BCR-ABL mutation testing in chronic myeloid leukemia have been compiled by a panel of experts appointed by the European LeukemiaNet (ELN) and European Treatment and Outcome Study and are here reported. Based on a critical review of the literature and, whenever necessary, on panelists' experience, key issues were identified and discussed concerning: (1) when to perform mutation analysis, (2) how to perform it, and (3) how to translate results into clinical practice. In chronic phase patients receiving imatinib first-line, mutation analysis is recommended only in case of failure or suboptimal response according to the ELN criteria. In imatinib-resistant patients receiving an alternative TKI, mutation analysis is recommended in case of hematologic or cytogenetic failure as provisionally defined by the ELN. The recommended methodology is direct sequencing, although it may be preceded by screening with other techniques, such as denaturing-high performance liquid chromatography. In all the cases outlined within this abstract, a positive result is an indication for therapeutic change. Some specific mutations weigh on TKI selection. © 2011 by The American Society of Hematology.

Transformed acute myeloid leukemia in myelofibrosis results in a median survival of less than 5months. We identified 46 of 1048 myelofibrosis patients in the European Group for Blood and Marrow Transplantation registry who received allogeneic stem cell transplantation for acute leukemia evolving from myelofibrosis. The cumulative incidence of treatment-related mortality at 1year was 28% (95% confidence interval, 14 to 42) and of relapse at 3years was 47% (95% confidence interval, 31 to 63). The 3-year progression-free (PFS) and overall survival (OS) rates were 26% and 33%, respectively. The only significant factor for survival was complete remission versus no complete remission before transplantation (69% versus 22%, P= 008); however, complete remission was achieved only in 8 patients. Allogeneic stem cell transplantation can cure myelofibrosis patients transformed to leukemia. © 2014 American Society for Blood and Marrow Transplantation.

BACKGROUND: Nilotinib is a selective, potent BCR-ABL inhibitor. Previous studies demonstrated the efficacy and safety of nilotinib in Philadelphia chromosome-positive chronic myeloid leukemia patients in chronic phase (CML-CP) or accelerated phase who failed prior imatinib. METHODS: This expanded access trial further characterized the safety of nilotinib 400 mg twice daily in patients with CML-CP (N = 1422). RESULTS: In this large, heavily pretreated population, nilotinib demonstrated significant efficacy, with complete hematologic response and complete cytogenetic response achieved in 43% and 34% of patients, respectively. Responses were rapid, mostly occurring within 6 months, and were higher in patients with suboptimal response to imatinib, with 75% and 50% achieving major cytogenetic response and complete cytogenetic response, respectively. At 18 months, the progression-free survival rate was 80%. Most patients achieved planned dosing of 400 mg twice daily and maintained the dose >12 months. Nonhematologic adverse events (AEs) were mostly mild to moderate and included rash (28%), headache (25%), and nausea (17%). Grade 3 or 4 thrombocytopenia (22%), neutropenia (14%), and anemia (3%) were low and managed by dose reduction or brief interruption. Grade 3 or 4 elevations in serum bilirubin and lipase occurred in 4% and 7% of patients, respectively. The incidence of newly occurring AEs decreased over time. Of patients who experienced a dose reduction because of AEs and attempted a re-escalation, 87% successfully achieved re-escalation to the full dose. CONCLUSIONS: This large study confirms that nilotinib was well tolerated and that grade 3 or 4 AEs occurred infrequently and were manageable through transient dose interruptions.

The prognosis value of interim positron emission tomography (PET) remains controversial in diffuse large Bcell lymphoma (DLBCL) patients because of the absence of consensus on criteria able to early identify good and bad responders to treatment. Visual interpretation using the International Harmonization Project (IHP) criteria, primarily established for end of treatment evaluation, was related to a low positive predictive value of treatment failure. The 5- point scale (5PS) that refers the residual uptake to the liver as background tissue was shown to slightly reduce falsepositive interim PET interpretations compared to IHP criteria. Semiquantification of fluorodeoxyglucose (FDG) uptake using standardized uptake value (SUV) and assessment of reduction of maximum SUV (SUVmax) between baseline and interim PET drastically improves both the interpretation accuracy and the interobserver reproducibility, and better predicts patient outcome than visual analysis. This latter approach is feasible in a multicenter setting and allows clinicians to design a risk-adapted therapeutic strategy based on early PET response assessment. © Springer Science+Business Media, LLC 2012.
