A new aromatic polyketide, alternaphenol B2 (1), and four known compounds (2-5) were isolated from the coral-derived fungus Parengyodontium album SCSIO SX7W11. Their structures were elucidated by high-resolution mass spectrometry, 1D and 2D NMR spectroscopy and comparison with reported literatures. Compounds 1 and 2 exhibited selective inhibitory activity against isocitrate dehydrogenase mutant R132H (IDH1m), with IC₅₀ values of 41.9 and 27.7 μM, respectively. Our findings thus provide a fresh incentive for investigation on IDH1m inhibitors as lead compounds for cancer treatment.

Clinical and radiological response of Maffucci related enchondromas to mutant IDH1 inhibitor Ivosidenib

Article

作者: Funck-Brentano, Thomas ; Cohen-Solal, Martine ; Ducray, François ; Mandonnet, Emmanuel

Ollier Disease (OD) and Maffucci syndrome (MS) is a rare bone disorder that affects the growth and development of the bones, with an estimated prevalence of 1 in 100,000 people. It is associated with somatic mosaicism of isocitrate dehydrogenase-1 (IDH1) or 2 (IDH2) pathogenic variants. Ivosidenib is indicated for the treatment of acute myeloid leukemia and locally advanced or metastatic cholangiocarcinoma and is currently investigated in low-grade glioma with a susceptible isocitrate dehydrogenase-1 (IDH1) pathogenic variant, but its effects in patients with OD or MS are unknown. We here report the first case of a patient with MS who was treated with Ivosidenib for recurrent IDH-1 mutated glioma. Besides the stabilization of the tumor size, the patient observed significant improvement in his enchondromas that became stiffer, with reduced pain, and significant modification of the mineralization of the enchondromas observed on X-rays. This first case report provides hope for the medical management of patients suffering because of OD or MS. Future clinical research is urgently needed to evaluate long-term benefit risk profile of IDH inhibitors in these rare diseases.

Olutasidenib: a novel mutant IDH1 inhibitor for the treatment of relapsed or refractory acute myeloid leukemia

Review

作者: Cortes, Jorge E.

INTRODUCTION:

Recurrent mutations in isocitrate dehydrogenase 1 (mIDH1) occur in about 7% to 14% of all cases of acute myeloid leukemia (AML). The discovery of targetable mutations in AML, including IDH mutations, expanded the therapeutic landscape of AML and led to the development of targeted agents. Despite significant advances in current treatment options, remission and overall survival rates remain suboptimal. The IDH1 inhibitor, olutasidenib, demonstrated encouraging safety and clinical benefits as monotherapy in patients with relapsed or refractory (R/R) mIDH1 AML.

AREAS COVERED:

This review outlines the olutasidenib drug profile and summarizes key safety and efficacy data, focusing on the 150 mg twice daily dose from the pivotal registrational cohort of the phase 2 trial that formed the basis for the US Food and Drug Administration approval of olutasidenib in patients with R/R AML with a susceptible IDH1 mutation.

EXPERT OPINION:

Olutasidenib offers patients with R/R mIDH1 AML a new treatment option, with improved complete remission and a longer duration of response than other targeted mIDH1 treatment options. Olutasidenib provided clinical benefit with a manageable safety profile. Additional analyses to further characterize the safety and efficacy of olutasidenib in frontline and R/R settings as monotherapy and as combination therapy are ongoing.

Servier snags FDA approval for Voranigo, the first targeted therapy for a common type of brain tumor

This marks the first FDA approval of a systemic therapy for patients with grade 2, IDH-mutant gliomas. Servier has expanded its IDH drug armamentarium with the FDA approval for an IDH1/2 dual inhibitor. The approval represents the first major treatment advance in low-grade brain cancer in more than two decades.The new FDA approval is for Servier’s Voranigo, or vorasidenib, for adult and children ages 12 and older with low-grade glioma with a susceptible IDH1 or IDH2 mutation. As the FDA noted in its press release, this marks the first approval of a systemic therapy for this type of grade 2 IDH-mutant brain cancer, which includes oligodendrogliomas and astrocytomas.Servier obtained Voranigo through its $2 billion acquisition of Agios Pharmaceuticals’ oncology business in 2021. Royalty Pharma, which earlier this year acquired a stake in Agios’ royalty payments for Voranigo, has projected the drug could reach more than $1 billion in annual peak sales in the U.S.Gliomas are the most common primary malignant brain tumors in adults, and IDH1 or IDH2 mutations are present in nearly all grade 2 diffuse gliomas in adults. By Royalty’s estimates, there are around 1,500 new diagnoses for these two IDH-mutant gliomas each year in the U.S.Current therapeutic interventions for these patients are more than 20 years old and are all used off label, Islam Hassan, M.D., senior medical director at Servier, noted in an interview with Fierce Pharma ahead of Tuesday’s FDA decision.Before Voranigo, Servier already has the IDH1 inhibitor Tibsovo and the IDH2 inhibitor Idhifa. Although doctors have been using the two meds off-label because of the lack of treatment options, neither was approved for brain cancer.Voranigo, for its part, was designed to penetrate the blood-brain barrier to be effective against brain tumors, Hassan explained. In a phase 3 trial coded INDIGO, Voranigo significantly reduced the risk of tumor progression or death by 61% compared with placebo among patients with residual or recurrent grade 2 IDH-mutant glioma. These patients had undergone no previous treatment other than surgery.In addition, Voranigo also showed a statistically significant benefit in delaying the need for the next treatment, slashing the risk for further treatment by 74% in the study.The trial is ongoing to gather overall survival data. Still, Hassan argued that the progression-free survival data are just as important, because these tumors will continue to grow and penetrate the brain and may develop into high-grade disease.Besides the Voranigo monotherapy regimen, Servier has been evaluating the IDH inhibitor alongside Merck’s immunotherapy Keytruda in recurrent or progressive IDH1-mutant gliomas. While anti-PD-1 antibody drugs like Keytruda have been largely unsuccessful in brain tumors, Hassan pointed to a previous study in which patients received Voranigo and Keytruda before surgery. In tissues collected from surgery, Servier noticed some changes in the immune microenvironment that Hassan said warrant further development of this combination.Servier is also testing Voranigo alongside the chemotherapy temozolomide in high-grade IDH-mutant glioma. As Hassan noted, these patients with grade 4 gliomas are typically excluded from other clinical trials.The FDA approval triggers a $200 million milestone payment from Servier to Agios, plus a $905 million payment from Royalty to Agios in exchange for a 15% royalty on U.S. net sales of up to $1 billion for the therapy.

HUTCHMED Initiates the RAPHAEL Registrational Phase III Trial of HMPL-306 for Patients with IDH1- and/or IDH2-Mutated Relapsed/Refractory Acute Myeloid Leukemia in China

HONG KONG and SHANGHAI, China and FLORHAM PARK, N.J., May 14, 2024 (GLOBE NEWSWIRE) -- HUTCHMED (China) Limited (“HUTCHMED”) (Nasdaq/AIM:HCM; HKEX:13) today announces that it has initiated a registrational Phase III clinical trial of HMPL-306 in patients with mutated isocitrate dehydrogenase (“IDH”) 1 or 2 relapsed / refractory acute myeloid leukemia (“AML”) in China. The first patient received their first dose on May 11, 2024. HMPL-306 is a novel dual-inhibitor of IDH1 and IDH2 enzymes. Mutations of IDH1 and IDH2 have been implicated as drivers of certain hematological malignancies, gliomas and solid tumors, particularly among AML patients. Although some IDH inhibitors have been approved in certain markets for AML, isoform switching between the cytoplasmic mutant IDH1 and mitochondrial mutant IDH2 often leads to acquired resistance to single inhibitors of IDH1 or IDH2. Targeting both IDH1 and IDH2 mutations may provide therapeutic benefits in cancer patients by overcoming this acquired resistance. RAPHAEL is a multicenter, randomized, open-label, registrational Phase III clinical trial designed to evaluate the safety and efficacy of HMPL-306 as a monotherapy in patients with relapsed or refractory AML harboring IDH1 and/or IDH2 mutations. The primary endpoint of overall survival (OS) and the secondary endpoints, including event-free survival (EFS) and complete remission (“CR”) rate, will be tested in comparison with current salvage chemotherapy regimens. The Company is looking to enroll approximately 320 patients for this registrational study, which is being led by principal investigator Prof Xiaojun Huang of Peking University People’s Hospital. Additional details may be found at clinicaltrials.gov, using identifier NCT06387069. The study follows positive data from a two-stage, open-label Phase I study evaluating the safety, pharmacokinetics, pharmacodynamics and efficacy of HMPL-306 in this indication (NCT04272957). The first-in-human dose-escalation stage data was presented at the European Hematology Association Congress (“EHA”) in June 2023.1 Results of the dose expansion stage of the study in over 50 patients demonstrated promising CR rates at the recommended Phase II dose are expected to be presented at the EHA Congress in June 2024. About IDH and Hematological Malignancies IDHs are critical metabolic enzymes that help to break down nutrients and generate energy for cells. When mutated, IDH creates a molecule that alters the cell’s genetic programming and prevents cells from maturing. IDH1 or IDH2 mutations are common genetic alterations in various types of blood and solid tumors, including AML with approximately 14-20% of patients having mutant IDH genes, myelodysplastic syndrome (MDS), myeloproliferative neoplasms (MPNs), low-grade glioma and intrahepatic cholangiocarcinoma. Mutant IDH isoform switching, either from cytoplasmic mutant IDH1 to mitochondrial mutant IDH2, or vice versa, is a mechanism of acquired resistance to IDH inhibition in AML and cholangiocarcinoma.2,3,4 According to the National Cancer Institute (NCI), there will be approximately 20,380 new cases of AML in the U.S. in 2023 and the five-year relative survival rate is 31.7%5. Currently, the U.S. Food and Drug Administration (FDA) has approved two drugs for IDH1 mutation and one drug for IDH2 mutation, but no dual inhibitor targeting both IDH1 and IDH2 mutants has been approved. There were an estimated 19,700 new cases of AML in China in 2018 and is estimated to reach 24,200 in China in 2030.6 In China one IDH1 inhibitor was approved in 2022. About HUTCHMED HUTCHMED (Nasdaq/AIM:HCM; HKEX:13) is an innovative, commercial-stage, biopharmaceutical company. It is committed to the discovery, global development and commercialization of targeted therapies and immunotherapies for the treatment of cancer and immunological diseases.
