COMMODORE is an open-label, randomized study of gilteritinib versus salvage chemotherapy in adult patients who have relapsed or refractory AML in China and other countries. Astellas has stopped enrollment in the trial and patients in the chemotherapy arm will be offered the opportunity to receive gilteritinib.

Earlier this year, the China National Medical Products Administration (NMPA) granted conditional approval to gilteritinib for the treatment of adult patients who have relapsed or refractory AML with a FLT3 mutation detected by a fully validated test. Approval was granted under an expedited pathway, following NMPA’s acceptance of gilteritinib for priority review in July 20201 and its inclusion in the third batch of overseas new drugs urgently needed in clinical settings in November 2020.2

Astellas plans to submit results of COMMODORE to the NMPA in support of full approval. Detailed results will also be submitted to a peer-reviewed journal and/or scientific congress.

"In COMMODORE, patients receiving gilteritinib lived longer than those receiving salvage chemotherapy, confirming the overall survival benefit seen in the Phase 3 ADMIRAL trial," said Andrew Krivoshik, M.D., Ph.D., Senior Vice President and Global Therapeutic Area Head, Oncology Development. "For these patients, who have limited treatment options, the new findings provide additional evidence supporting gilteritinib as a treatment option."

AML is a cancer that impacts the blood and bone marrow,3 and its incidence increases with age.4 It is one of the most common types of leukemia in adults.5 Every year, it is estimated that more than 85,000 people in China are diagnosed with leukemia.6

In previous clinical trials, the safety of gilteritinib was evaluated in 319 patients with relapsed or refractory AML who had received at least one dose of 120 mg gilteritinib daily.7 The most frequent all-grade adverse reactions (frequency ≥ 10%) with gilteritinib were alanine aminotransferase (ALT) increased (25.4%), aspartate aminotransferase (AST) increased (24.5%), anemia (20.1%), thrombocytopenia (13.5%), febrile neutropenia (12.5%), platelet count decreased (12.2%), diarrhea (12.2%), nausea (11.3%), blood alkaline phosphatase increased (11%), fatigue (10.3%), white blood cell count decreased (10%), and blood creatine phosphokinase increased (10%). One fatal adverse reaction of differentiation syndrome occurred in patients receiving gilteritinib. The most frequent (frequency ≥3%) serious adverse reactions were febrile neutropenia (7.5%), ALT increased (3.4%), and AST increased (3.1%). Other clinically significant serious adverse reactions included electrocardiogram QT prolonged (0.9%) and posterior reversible encephalopathy syndrome (0.3%).

Qihan Biotech Raises Additional USD 67 Million in Series A++ Financing. Funds to Advance Pipeline of Novel Cell and Organ Therapies

On March 29, 2021 Qihan Biotechology a leader in applying multiplexable genome editing technology to cell therapies and organ transplantation, reported that it has raised an additional $67million in Series A++ financing (Press release, Qihan Biotech, MAR 29, 2021, View Source [SID1234584524]). Proceeds from the financing will primarily be used to advance Qihan’s pipeline of novel cell therapies in IND-enabling studies and hypoimmunity projects, and expansion of the company’s GMP manufacturing facilities.

The financing was backed by new investors including leading biomedical venture capital firm, Lilly Asia Ventures and Matrix Partners China, as well as existing shareholders, Sequoia and CMB International. With these investments, Qihan’s total Series A financing raised to date has exceeded $100 million.

Cell therapy is rapidly becoming an important weapon against cancer and other serious diseases, but technological optimization in cell therapy remains a critical need. Autologous cell therapy can avoid immune rejection to a certain extent, but prohibitive costs put these therapies out of reach for many patients. The allogeneic cell therapy currently available requires patients to take immunosuppressive drugs, often for life, to avoid rejection of cells by the patient’s immune system. A cost-effective solution to these two issues would bring hope to millions of patients and families around the world.

Qihan is using its deep professional knowledge of transplantation immunology to develop that solution. The Company’s research team uses high-throughput multiplexable gene editing technology to develop "immune-privileged" human stem cells, that will not be attacked or rejected. Qihan is focused on developing off-the-shelf, or universal, cell therapy products, which compared to autologous cell therapy products, are more widely targeted and more affordable to patients.

Through its experience with xenotransplantation animal models, Qihan is able to identify and edit the genes in human cells that affect immune rejection to achieve low- to risk-free allogeneic cell therapy. The Company has advanced the editing process, directly editing stem cells, and inducing their proliferation and differentiation to produce high volumes of immune cells. This not only reduces production costs, but improves the efficiency and targeting of gene editing, greatly improving the clinical accessibility of cell therapy products.

The Company’s first cell therapy products for human clinical trials are now in development. Considering the long research period and difficulty of xenotransplantation products, Qihan may commercialize cell therapy products prior to xenotransplantation.

"We are delighted to expand our investor base with support from high caliber investors including Lilly Asia Ventures," said Dr. Luhan Yang, founder and CEO of Qihan Biotech. "The expanded Series A funds will allow us to advance both Qihan’s near-term focus of developing allogeneic cell therapies and our long-term mission of developing xenogeneic organs for clinical application.

"We will also be working toward growing our GMP manufacturing capacity to support rapid development and scale-up of our therapies. We look forward to continuing to expand our pipeline and working toward our vision of a world in which cell and organ therapies are universally available to patients."

HUTCHMED Initiates International Phase I Trials of IDH1/2 Dual Inhibitor in Patients with Advanced Solid Tumors or Hematological Malignancies

On March 29, 2021 Hutchison China MediTech Limited ("HUTCHMED") (Nasdaq/AIM: HCM) reported that it has initiated two international Phase I studies of HMPL-306, its novel selective small molecule dual inhibitor of isocitrate dehydrogenase ("IDH") 1 and 2 mutations (Press release, , MAR 29, 2021, View Source [SID1234583625]). One trial is in patients with advanced solid tumors and one trial is in patients with hematological malignancies. Both trials have sites in the US and Europe. The first international patient was dosed on March 25, 2021, following a Phase I trial that was initiated in China in the second half of 2020. This new program is a demonstration of HUTCHMED’s accelerating and expanding global clinical development presence.

These two trials are multi-center studies to evaluate the safety, tolerability pharmacokinetics, pharmacodynamics and preliminary efficacy of HMPL-306. The first trial is in solid tumors (including but not limited to gliomas, chondrosarcomas, or cholangiocarcinomas), while a second trial is in advanced relapsed, refractory or resistant hematological malignancies that harbor IDH1 or IDH2 mutations. The first stage of each study is a dose escalation phase where cohorts of patients will receive ascending oral doses of HMPL-306 to determine the maximum tolerated dose and/or the recommended Phase II dose ("RP2D"). The second stage is a dose expansion phase where patients will receive HMPL-306 to further evaluate the safety, tolerability, and clinical activity at the RP2D. Additional details may be found at clinicaltrials.gov, using identifiers NCT04762602 and NCT04764474, respectively.

The MD Anderson Cancer Center ("MDACC") is the lead institution on both studies. The lead investigator for the hematological malignancies study is Dr. Farhad Ravandi, the Janiece and Stephen A. Lasher Professor of Medicine and Chief of Section of Developmental Therapeutics in the Department of Leukemia at The University of Texas MDACC. The lead investigator for the solid tumor study is Dr. Filip Janku, Associate Professor, Department of Investigational Cancer Therapeutics at The University of Texas MDACC.

A Phase I study of HMPL-306 is underway in China, with the first patient dosed in July 2020. Additional details of that study may be found at clinicaltrials.gov, using identifier NCT04272957.

HMPL-306 is HUTCHMED’s ninth innovative oncology drug candidate that it has discovered that has entered clinical development and the sixth to enter global clinical development. Cytoplasmic mutant IDH1 and mitochondrial mutant IDH2 have been known to switch to the other form when targeted by an inhibitor of IDH1 mutant alone or IDH2 mutant alone. By targeting both IDH1 and IDH2 mutations, HMPL-306 could potentially provide therapeutic benefits in cancer patients harboring either IDH mutation, and may address acquired resistance to IDH inhibition through isoform switching.

About IDH and 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, 2-hydroxyglutarate ("2-HG"). Reduction in 2-HG levels can be used as a marker of target engagement by an IDH inhibitor. IDH1 or IDH2 mutations are common genetic alterations in various types of blood and solid tumors, including acute myeloid leukemia ("AML") with approximately 20% of patients having mutant IDH genes, myelodysplastic syndrome (MDS), myeloproliferative neoplasms (MPNs), low-grade glioma and intrahepatic cholangiocarcinoma ("IHCC"). 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.1,2,3 Currently, the U.S. Food and Drug Administration (FDA) has approved one drug for IDH1 mutation and one drug for IDH2 mutation, but no dual inhibitor targeting both IDH1 and IDH2 mutants has been approved.

In the US, it is estimated that there were approximately 20,000 new cases of AML in 2020 and the five-year relative survival rate is 28.7%.4

IDH mutations are present in a number of solid tumors, including malignant glioma and IHCC. In the US, the annual incidence of malignant glioma is estimated to be 20,000, 50-70% of which are glioblastoma.5,6 Approximately 60-80% of Grade 2 or 3 glioma and secondary glioblastoma harbor IDH mutations.7 IHCC accounts for 10-20% of primary liver cancer, which was estimated to be diagnosed in 42,810 US patients in 2020.8,9 Approximately 20-30% of IHCC harbors IDH mutations.10
