bluebird bio Announces New Interim Data from Phase 1 (HGB-206) Study of LentiGlobin™ Gene Therapy in Patients with Severe Sickle Cell Disease at Annual Congress of the European Hematology Association

Del

bluebird bio, Inc. (Nasdaq: BLUE) today announced new interim data from the ongoing HGB-206 Phase 1 multicenter clinical study of LentiGlobin investigational gene therapy in patients with severe sickle cell disease (SCD) will be presented in an oral presentation on Saturday, June 16 at the 23rd Congress of the European Hematology Association (EHA) by Julie Kanter, M.D., Medical University of South Carolina, Charleston, South Carolina.

“The consistent production of increased amounts of anti-sickling HbAT87Q in the Group C patients reflects the substantial positive impact of the changes introduced with the amended HGB-206 study protocol and refined manufacturing process. All four Group C patients with greater than or equal to three months follow-up are making over 30 percent anti-sickling HbAT87Q. The first patient treated, now with six months of follow-up, is producing over 60 percent anti-sickling HbAT87Q with a normal total hemoglobin level of 14.2 g/dL,” said David Davidson, M.D., chief medical officer, bluebird bio. “The upward trajectory in Group C at these early time points suggests the potential for these patients to exceed the initially proposed therapeutic target of 30 percent anti-sickling HbAT87Q. We continue to define the development plan with regulatory authorities, and with further follow-up, we hope to see even higher levels of HbAT87Q, as well as sustained clinical benefit for patients.”

SCD is a genetic disease that causes the protein in red blood cells, called hemoglobin, to be misshapen. As a result of this abnormal hemoglobin, many affected individuals live with severe anemia and vaso-occlusive events which include severe, recurrent pain crises that lead to organ damage and shortened life span.

“The early data from Group C patients are very exciting and provide increasing confidence that LentiGlobin has the potential to deliver transformative benefit to patients. The longer-term data from patients treated earlier in the study show that levels of anti-sickling HbAT87Q in patients with SCD treated with LentiGlobin remain stable for at least two years,” said Dr. Kanter, a lead investigator of the HGB-206 study. “Treatment options that can address the underlying cause of sickle cell disease are limited and LentiGlobin gene therapy has the potential to prevent or substantially reduce damaging symptoms associated with this debilitating disease.”

Recent Progress in Gene Therapy for Severe Sickle Cell Disease: Updated Interim Results from a Phase 1 Clinical Study of LentiGlobin Gene Therapy (Abstract S836)

Presenter: Julie Kanter, M.D., Medical University of South Carolina, Charleston, SC
Date & Time: Saturday, June 16, 2018, 12:30 – 12:45 p.m. CEST (6:30 a.m. EDT)
Location: Room A8

HGB-206 is an ongoing, open-label study designed to evaluate the safety and efficacy of LentiGlobin gene therapy for the treatment of adults with severe SCD. Patients in this study are divided into three cohorts: A, B and C. Patients in Group A were treated under the original study protocol. Patients in Group B were treated under an amended study protocol that included a refined Drug Product (DP) manufacturing process intended to increase DP vector copy number (VCN) as well as changes to improve engraftment of gene-modified stem cells. Patients in both Group A and B had DP made from stem cells collected using bone marrow harvest. Patients in Group C were also treated under the amended study protocol, but received LentiGlobin gene therapy made from stem cells collected from peripheral blood after mobilization with plerixafor rather than via bone marrow harvest. Results, as of May 15, 2018, include:

  • Group C: 6 patients treated under the amended study protocol and with DP manufactured using the refined process, median (range) follow-up 3 (1.2 – 6.0) months:
    • 4 of 6 patients had ≥ 3 months follow up, and were producing 3 – 6 g/dL of HbAT87Q by 3 months
    • 1 patient was producing 8.8 g/dL of HbAT87Q and a total hemoglobin level of 14.2 g/dL at 6 months
    • Median transduced CD34+ cells: 81%
    • Median DP cell dose: 7.1 x 106 CD34+ cells
    • Median DP VCN (copies per diploid genome): 4
    • Overall safety profile remains generally consistent with myeloablative conditioning
    • Continued feasibility of plerixafor mobilization and apheresis observed
  • Group B: 2 patients treated under the amended study protocol and with DP manufactured using stem cells from bone marrow harvest with ≥ 9 months follow up:
    • Patient 1312, who received LentiGlobin manufactured entirely using a refined manufacturing process, was producing 7.2 g/dL HbAT87Q and 12.8 g/dL of total hemoglobin (56% HbAT87Q) at 9 months of follow-up
    • Patient 1313, who received LentiGlobin manufactured using a combination of the original and the refined manufacturing processes, was producing 3.2 g/dL HbAT87Q and 11.0 g/dL of total hemoglobin (29% HbAT87Q) at 15 months of follow-up
  • Group A: Long-term data on 7 patients in the initial study cohort with ≥ 2 years follow-up:
    • Steady levels of LentiGlobin vector and HbAT87Q were maintained through 2 years (median follow-up: 24.2 months; range: 22.8 – 32.9)
    • Median transduced CD34+ cells: 25%
    • Media DP cell dose: 2.1 x 106 CD34+ cells
    • Median DP VCN: 0.6
    • Median (range) total hemoglobin at last study visit was 9.1 (7.1 – 11.4) g/dL

About SCD

Sickle cell disease (SCD) is a serious, progressively debilitating, and life-threatening genetic disease. SCD results from production of abnormal sickle hemoglobin (HbS), which leads to sickled red blood cells (RBCs) and hemolysis. As a result of this abnormal hemoglobin, many affected individuals live with severe anemia and vaso-occlusive events which include severe, recurrent pain crises that lead to organ damage and shortened life span.

Where adequate medical care is available, common treatments for patients with SCD largely revolve around prevention of infection, and management and prevention of acute sickling episodes. Chronic management includes a limited number of pharmaceutical treatment options and, in certain cases, chronic transfusions. Allogeneic hematopoietic stem cell transplant (HSCT) is currently the only available option with the potential to correct the genetic deficiency in SCD. However, its use is limited to certain pediatric patients with severe disease who have an unaffected matched sibling donor. Complications of allogeneic HSCT include a risk of treatment-related mortality, graft failure, graft-versus-host disease (GvHD) and opportunistic infections, particularly in patients who undergo non-sibling-matched allogeneic HSCT.

Henley & Partners Enlarges Executive Committee to Manage Expansion and Growth14.12.2018 14:00Pressemelding

Residence- and citizenship-by-investment programs have firmly established themselves over the past few years as the new frontier in terms of freedom, flexibility, and future-readiness, both for the countries issuing these programs and for the individual investors participating in them. The societal and economic value these programs generate is undisputed. The investment migration industry as a whole is currently grossing roughly USD 18 billion per year, with an expectation that it will hit the USD 20 billion mark very soon. Foreign direct investment (FDI) is now considered the lifeblood of economic growth for many developing and recovering smaller countries around the world. As such, the number of investment migration programs has been increasing rapidly, from just a handful of programs in the 1980s and 1990s to over 100 countries that now have investment migration provisions in their laws. There are more than 60 active programs today, with Moldova and Montenegro — both fast-growing Eu

Vargatef® plus docetaxel could be an option after failure of immunotherapy in lung cancer14.12.2018 09:07Pressemelding

Boehringer Ingelheim announced today the first interim results of VARGADO, an ongoing non-interventional study in routine clinical practice in Germany evaluating the efficacy and safety of Vargatef® (nintedanib) and docetaxel in patients with stage III/IV locally advanced or metastatic non-small cell lung cancer (NSCLC) of adenocarcinoma histology. The study consists of three cohorts, two of which allow for prior treatment with immune checkpoint inhibitors (ICIs) either in combination with chemotherapy in the first-line or as monotherapy in the second-line of treatment. The interim results from Cohort B (first-line chemotherapy, second-line immune checkpoint inhibitors, third-line Vargatef® plus docetaxel) were presented today at ESMO Immuno-Oncology Congress 2018 in Geneva.1 Despite a limited sample size, the VARGADO study adds to the body of evidence for nintedanib in lung adenocarcinoma following pre-treatment with chemotherapy and ICIs.1,3 The addition of nintedanib to docetaxel ha
