Scientists discover new 'architecture' in corn

Phys.org | January 21, 2019

New research on the U.S.'s most economically important agricultural plant corn has revealed a different internal structure of the plant than previously thought, which can help optimize how corn is converted into ethanol. "Our economy relies on ethanol, so it's fascinating that we haven't had a full and more precise understanding of the molecular structure of corn until now," said LSU Department of Chemistry Assistant Professor Tuo Wang, who led this study that will be published on Jan. 21 in Nature Communications. "Currently, almost all gasoline contains about 10 percent ethanol. One-third of all corn production in the U.S., which is about 5 billion bushels annually, is used for ethanol production. Even if we can finally improve ethanol production efficiency by 1 or 2 percent, it could provide a significant benefit to society." Wang and colleagues are the first to investigate an intact corn plant stalk at the atomic level using high-resolution techniques. The LSU team includes Postdoctoral Researcher Xue Kang and two graduate students, Malitha Dickwella Widanage from Colombo, Sri Lanka, and Alex Kirui from Nakuru, Kenya.

Imara Announces Primary Endpoint Change in the Ardent Phase 2b Clinical Trial of Tovinontrine (IMR-687) in Sickle Cell Disease

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. About Imara 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.
