Flamingo Therapeutics, Inc. | September 09, 2021
Flamingo Therapeutics, Inc., a biotechnology company pioneering RNA-targeting therapies in oncology, today announced that it has entered into an agreement with Ionis Pharmaceuticals to develop RNA-targeted therapies to treat various forms of cancer. This alliance is an expansion of an existing collaboration with Ionis on the FLAME™ discovery engine, following Flamingo's Series A financing in 2020.
The agreement and discovery alliance will leverage Flamingo's deep expertise in oncology and long non-coding RNAs (lncRNAs) in combination with Ionis' expertise in RNA-targeted drug discovery and development to advance candidates against targets considered undruggable with traditional approaches. Flamingo's pipeline will include three clinical-stage programs from Ionis, inhibitors of STAT-3, Androgen Receptor (AR) and IRF4, and one preclinical-stage program that targets MALAT1, a well-characterized lncRNA target. Flamingo will also advance its proprietary discovery engine, FLAME (Flamingo LncRNA Antisense Mining Engine), that addresses lncRNAs, a large and untapped class of disease-causing targets within the dark matter of the human genome.
"We're thrilled to strengthen our relationship with Ionis who has been at the forefront of RNA-targeted therapy for thirty years," said Michael Garrett, Chief Executive Officer of Flamingo. "We believe the combination of Ionis' leadership in RNA and our cutting-edge lncRNA discovery engine will expand the opportunities for applying RNA-targeted approaches to oncology."
"We are pleased that Flamingo is leveraging their core strengths in developing novel cancer medicines to advance innovative Ionis-discovered oncology therapies where there is an unmet need," said Brett P. Monia, Ph.D., Ionis' chief executive officer.
In connection with the alliance, Rob MacLeod, Ph.D., VP, Oncology Research & Development of Ionis, will serve as Chief Scientific Officer of Flamingo. Under the terms of the agreement, Ionis is eligible to receive milestone payments and royalties on future product sales of the STAT3, AR, IRF4 and MALAT1 programs. Flamingo retains full rights to its FLAME platform and all lncRNA programs outside of MALAT1.
Flamingo Therapeutics was founded by VIB, Ghent University, KU Leuven, the University of Michigan, Kurma Partners and PMV, based on pioneering work led by Professor Jean-Christophe Marine (VIB-KU Leuven), Professor Pieter Mestdagh (Ghent University) and Professor Arul Chinnaiyan (University of Michigan). These scientific teams broke new ground on non-coding RNA genes in cancer and were among the first to show a role for lncRNAs as disease drivers in oncology.

CELL AND GENE THERAPY
Imara | November 22, 2021
Imara Inc. a clinical-stage biopharmaceutical company dedicated to developing and commercializing novel therapeutics to treat patients suffering from rare inherited genetic disorders of hemoglobin and other serious diseases, today announced a change to the primary endpoint for the Ardent clinical trial, a Phase 2b study of tovinontrine (IMR-687) in patients with sickle cell disease (SCD), based on the recommendation of the U.S. Food and Drug Administration (FDA).
Imara requested feedback from the FDA on the draft statistical analysis plan (SAP) for the Ardent trial in which fetal hemoglobin (HbF) response was the primary endpoint and annualized rate of vaso-occlusive crises (VOCs) was the key secondary endpoint. In reviewing the Ardent draft SAP and prior to any database lock for analysis, the FDA recommended that Imara change the primary endpoint to be annualized rate of VOCs. HbF response will continue to be evaluated as a key secondary endpoint. The endpoint revisions do not affect the conduct of the trial or operational aspects of the study. As part of its recommendation, the FDA suggested further interactions regarding the revised SAP and engagement on the potential of the current program for regulatory decision-making.
“We welcome the FDA’s recommendations and are in the process of changing the primary endpoint of the Ardent trial to be annualized rate of VOCs and moving HbF response to be a key secondary endpoint. A reduction in VOC rate is an established approval endpoint, and we are engaging the FDA further on this and related topics, including possible streamlined paths to registration.”
Rahul Ballal, Ph.D., President and Chief Executive Officer of Imara
Dr. Ballal continued, “In light of this endpoint revision, the previously planned fourth quarter interim analysis will no longer occur. That interim analysis had been designed to have a focus on safety and pharmacodynamic biomarkers, including HbF, but did not include a review of VOCs. The first review of data from the Ardent trial, including annualized VOC rate, will be conducted when all subjects have completed assessment at Week 24 or terminated early, and is planned for the first quarter of 2022, subject to our upcoming discussions with the FDA. Final data analysis from the Ardent trial remains on track for the second half of 2022. In June 2021, we reported promising data from our Phase 2a and open label extension clinical trials in SCD that demonstrated reduced annualized rates of VOCs in patients treated with tovinontrine versus placebo. We expect to present updated 12-month VOC data from our ongoing Phase 2a open label extension clinical trial at the American Society of Hematology Annual Meeting in December 2021.”
About the Ardent Phase 2b Clinical Trial
The Ardent Phase 2b clinical trial is a fully-enrolled, global, randomized, double-blind, placebo-controlled, multicenter study with approximately 115 adult patients with sickle cell disease (SCD) enrolled. The planned primary efficacy objective will be to evaluate the annualized rate of vaso-occlusive crises (VOCs) in patients dosed with tovinontrine (IMR-687) as compared to placebo. A key secondary endpoint will be to evaluate the proportion of all patients with fetal hemoglobin (HbF) response, defined as an absolute increase from baseline of at least 3% in HbF, as compared to placebo. Additional endpoints include the evaluation of the effect of tovinontrine versus placebo on other VOC-related outcome measures, HbF-associated biomarkers, markers of red blood cell hemolysis, white blood cell adhesion markers and quality of life measures over the course of a one-year treatment period.
The FDA has granted Orphan Drug, Fast Track and Rare Pediatric Disease designations and the European Commission has granted Orphan Drug designation for tovinontrine for the treatment of SCD.
About Tovinontrine (IMR-687)
Tovinontrine is a highly selective and potent small molecule inhibitor of phosphodiesterase-9 (PDE9). PDE9 selectively degrades cyclic guanosine monophosphate (cGMP), an active signaling molecule that plays a role in vascular biology and hemoglobin production in red blood cells. Lower levels of cGMP are found in people with sickle cell disease (SCD) and beta-thalassemia and are associated with reduced blood flow, increased inflammation, greater cell adhesion and reduced nitric oxide mediated vasodilation. Blocking PDE9 acts to increase cGMP levels, which is associated with several benefits including the potential reactivation of fetal hemoglobin (HbF), a natural hemoglobin produced during fetal development. Increased levels of HbF in RBCs have been demonstrated to improve symptomology and substantially lower disease burden in both patients with SCD and patients with beta-thalassemia.
About Sickle Cell Disease
Sickle cell disease (SCD), a hemoglobinopathy, is a rare inherited red blood cell disorder. The disease causes structural abnormalities in hemoglobin that cause red blood cells to become inflexible and elongated, ultimately blocking blood flow to organs, which can lead to vaso-occlusive crises (VOCs). SCD is characterized by debilitating pain, progressive multi-organ damage and early death. The global prevalence of SCD is estimated to be approximately 4.4 million patients, including an estimated 100,000 patients in the United States and 134,000 patients in the European Union.
Imara Inc. is a clinical-stage biotechnology company dedicated to developing and commercializing novel therapeutics to treat patients suffering from rare inherited genetic disorders of hemoglobin and other serious diseases. Imara is advancing tovinontrine (IMR-687), a highly selective, potent small molecule inhibitor of PDE9 that is an oral, potentially disease-modifying treatment currently in clinical development for sickle cell disease and beta-thalassemia and preclinical development for heart failure with preserved ejection fraction, or HFpEF. Imara is also advancing IMR-261, an oral activator of nuclear factor erythroid 2–related factor 2, or Nrf2.
