A single dose of MGTA-145 mobilized large numbers of hematopoietic stem cells in hours that engrafted robustly in primates MGTA-145-mobilized cells blocked graft-vs.-host disease (GvHD) in preclinical models MGTA-145 to enter the clinic in the first half of 2019
Für mich einer der Favoritenwerte schlechthin. Sie kommen jetzt mit MGTA-117 in die entscheidende klinische Phasen. Direkt dahinter 45. Sollte das mit der Umsetzung mit den ADC Wirkstoffen klappen, schlummert hier ein verborgener Schatz. Geld ist noch bis etwa Q2/3 22 da. Ein riesiges Potential mit enorm vielen Möglichkeiten. Für mich in den nächsten Jahren einer meiner Favoritenwerte neben HPHA . Mal sehen, wie sie die weitere Finanzierung im nächsten Jahr sichern können. Wahrscheinlich lizensieren sie in diesem Jahr den dritten Kandidaten von HPHA ein. Ich kann dir nur raten mal in den Jahresberichten und Patenten zu stöbern, um zu sehen was daraus werden könnte, wenn die Umsetzung gelingt. Die Risiken sind biotechüblich. Finanzierung und unvorhersehbare Ereignisse in der Entwicklung. Doch die vorklinischen Versuche deuten einen riesigen großen Erfolg an. Ich hab sie dieses Jahr in mein Jahresspieldepot gepackt. Magenta ist im Augenblick mit etwa 400 Mill. $ bewertet. Sollte es günstig auch mit den Corona Verzögerungen verlaufen sehe ich hier ein ähnliches Potential wie bei HPHA. Man braucht nur die Geduld und dicke Nerven. Liebe Grüße und viel Erfolg. BICYPAPA

CAMBRIDGE, Mass.--(BUSINESS WIRE)--Jan. 11, 2021-- Magenta Therapeutics (NASDAQ: MGTA), a clinical-stage biotechnology company developing novel medicines to bring the curative power of immune and blood systems reset via stem cell transplant to more patients, today highlighted progress across its stem cell mobilization and collection and targeted conditioning programs, and set expectations for 2021. These updates will be discussed during a webcast presentation at the 39th Annual J.P. Morgan Healthcare Conference on Thursday, January 14 at 7:50 a.m. PST / 10:50 a.m. EST.
?I?m exceptionally proud of the entire Magenta team who continued to adapt and execute across our portfolio, despite the disruptions that characterized 2020. This past year, we continued to drive our vision to bring immune and blood systems reset to more patients. We announced four pipeline-expanding partnerships, presented clinical and pre-clinical data across our pipeline and secured the capital that we expect can fund our operations into 2023. We continue to advance four ongoing and planned clinical trials that we believe can advance our portfolio in 2021 and, for MGTA-145 specifically, can provide proof-of-concept for stem cell mobilization across multiple diseases and the first clinical data for MGTA-117 targeted conditioning,? said Jason Gardner, D. Phil., President and Chief Executive Officer, Magenta. ?I am also delighted to welcome Alison Lawton?s return to Magenta?s Board of Directors. Alison brings extensive experience and leadership in both regulatory and business arenas, essential as the Magenta portfolio advances. We look forward to building on the momentum generated in 2020 as we relentlessly focus on execution.?
Stem Cell Mobilization and Collection
MGTA-145: Three Phase 2 Clinical Trials Ongoing or Planned
Autologous Stem Cell Transplant of Multiple Myeloma Patients. Previously announced ongoing enrollment continues for the Phase 2 investigator-initiated clinical trial of MGTA-145, used in combination with plerixafor, to mobilize and collect stem cells for autologous stem cell transplantation in multiple myeloma patients at Stanford University. Magenta expects that this trial will provide data on stem cell mobilization and collection, durability of engraftment in transplanted patients and disease outcomes, including progression-free survival. Initial data from the study are expected in mid-2021.
Allogeneic Donor Stem Cell Mobilization and Collection for Stem Cell Transplant in AML, ALL and MDS Patients. Through a collaboration with the National Marrow Donor Program®/Be The Match®, Magenta plans to initiate, within the next several weeks, a Phase 2 clinical trial using MGTA-145 to mobilize and collect stem cells from allogeneic donors for transplant in patients with AML, ALL and MDS. This clinical trial will evaluate stem cell mobilization, collection, cell quality, engraftment and disease outcomes, including Graft-versus-Host Disease (GvHD), which is of particular importance in the allogeneic transplant setting. Initial data from this clinical trial are expected in the second half of 2021.
Sickle Cell Disease ? Stem Cell Mobilization and Collection; Cell Characterization; Pre-Clinical Gene Modification Model. In collaboration with bluebird bio, Magenta plans to initiate a Phase 2 clinical trial in the second half of 2021 to evaluate MGTA-145, in combination with plerixafor, for the mobilization and collection of stem cells in adults and adolescents with sickle cell disease (SCD). Each party will characterize the cells and Magenta plans to gene-correct the cells and transplant them into established pre-clinical disease models to evaluate engraftment. Data from this clinical trial could provide proof-of-concept for MGTA-145, in combination with plerixafor, as the preferred mobilization regimen for patients with SCD and, more broadly, across all gene therapy applications where safe, reliable and rapid mobilization of quality stem cells for gene-modification and transplant are necessary components.
Magenta is developing MGTA-145 in combination with plerixafor to harness complementary mechanisms to mobilize hematopoietic stem cells (HSCs) for collection and transplantation. This combination has the potential to be the preferred mobilization regimen for safe, rapid and reliable mobilization and collection of HSCs and could improve outcomes in autologous and allogeneic stem cell transplantation.
MGTA-117: Plans to Initiate Phase 1 Clinical Trial in mid-2021; Initial Safety and Pharmacokinetics (PK) data to be assessed in the fourth quarter of 2021
AML and MDS. Magenta is completing its IND-enabling GLP toxicology studies and GMP manufacturing process for MGTA-117, the first antibody-drug conjugate (ADC) candidate from the company?s research platform for targeted conditioning of patients prior to receiving a stem cell transplant for blood cancers or gene therapy drug products. Later this month, Magenta expects to complete its initial discussions with the U.S. Food and Drug Administration regarding the design of the first-in-human clinical trial. Magenta expects to file an Investigational New Drug (IND) application and, upon approval, plans to initiate a Phase 1 clinical trial in mid-2021 to assess the safety and PK in the first cohort of patients in the fourth quarter of 2021.
MGTA-117, Magenta?s most advanced conditioning program, is a CD117-targeted antibody engineered for the transplant setting and conjugated to amanitin, a payload in-licensed from Heidelberg Pharma. MGTA-117 is designed to precisely deplete only hematopoietic stem and progenitor cells to clear space in the bone marrow prior to transplant, which supports long-term engraftment and disease outcomes in patients. MGTA-117 has shown high selectivity, potent efficacy, wide safety margins and broad tolerability in non-human primate models.
With focused allocation of resources on the Company?s clinical trials and advancement of its research platform, the Company now believes its cash position will fund its operations into the first quarter of 2023.
