Kronos Bio Announces First Patient Dosed in AGILITY Phase 3 Clinical Trial of Entospletinib in Patients With Newly Diagnosed NPM1-mutated Acute Myeloid Leukemia

On December 6, 2021 Kronos Bio, Inc. (Nasdaq: KRON), a company dedicated to transforming the lives of those affected by cancer, reported that the first patient has been dosed in the registrational Phase 3 AGILITY clinical trial of entospletinib, a selective inhibitor targeting spleen tyrosine kinase (SYK), in combination with standard of care anthracycline and cytarabine (7+3) chemotherapy (Press release, Kronos Bio, DEC 6, 2021, View Source [SID1234596475]). This trial is the first in acute myeloid leukemia (AML) to use measurable residual disease (MRD) as the primary endpoint and has the potential to support accelerated approval of entospletinib by the U.S. Food and Drug Administration (FDA) as a treatment for patients newly diagnosed with NPM1-mutated AML who are fit for intensive induction.

"With the initiation of this trial, we are taking an important step forward for patients with AML, a form of blood cancer that has been difficult to treat historically," said Norbert Bischofberger, Ph.D., president and chief executive officer of Kronos Bio. "Even with current therapies, about half of people newly diagnosed with NPM1-mutated AML will die from the disease within five years. The use of the novel endpoint of MRD provides a pathway to potentially bring entospletinib to patients more quickly."

Entospletinib is Kronos Bio’s lead product candidate, and the company expects to share data from the trial in the second half of 2023. The randomized, double-blind, placebo-controlled trial is designed to assess the efficacy and safety of entospletinib in combination with intensive induction and consolidation chemotherapy in approximately 180 adults who have been newly diagnosed with NPM1-mutated AML. This trial will test the hypothesis, based on robust preclinical and Phase 2 clinical data, that NPM1 mutation leads to dependency on SYK signaling. The NPM1 mutation is present in about 30% of all adult patients with AML.

"We are pleased to be participating in this trial, with the goal of improving outcomes for patients with AML," said Karamjeet S. Sandhu, M.D., assistant professor in the Department of Hematology and Hematopoietic Cell Transplantation at City of Hope, a world-renowned research and treatment organization near Los Angeles that was the first to dose a patient in the trial. "Patients with NPM1-mutated AML are in need of better treatment options, and we are excited that we are the first center to begin treating a patient in this trial."

The primary endpoint of the trial is MRD negative complete response (CR), as measured by molecular detection of mutant NPM1 alleles in bone marrow, which affords a high degree of sensitivity to detect MRD. Numerous clinical studies have shown that patients with NPM1 mutations who achieve MRD negative CR after induction chemotherapy survive longer than patients who achieve CR but have detectable MRD. If successful, this would be the first time MRD is used as the basis for seeking accelerated approval in AML.

The decision to proceed with this trial design was made after an End-of-Phase 2 discussion with the FDA. In the trial, patients will be randomized 1:1 to receive either entospletinib or placebo in combination with standard induction and consolidation chemotherapy. Remission and MRD status will be assessed after the first two cycles of chemotherapy and patients may receive up to a total of five cycles. Event-free survival (EFS) is a key secondary endpoint, and mature EFS data will potentially be used to support full approval.

Kronos Bio acquired entospletinib and another SYK inhibitor, lanraplenib, from Gilead Sciences in July 2020. As previously announced, under the agreement with Gilead, the initiation of the Phase 3 trial triggers a $29 million milestone payment from Kronos Bio to Gilead. The payment will be recorded in the fourth quarter.

Lanraplenib is being developed for the treatment of patients with relapsed/refractory FLT3-mutated AML and patients newly diagnosed with NPM1-mutated and/or​ FLT3-mutated AML ​who are older than 75 years old or are not eligible for intensive induction chemotherapy.

About Acute Myeloid Leukemia
Acute myeloid leukemia (AML) primarily affects adults and is one of the most difficult-to-treat blood cancers. AML starts in the bone marrow, impairing its ability to produce mature red blood cells, white blood cells and platelets. Without treatment, patients die within weeks to months from progressive bone marrow failure leading to infections, bleeding and heart failure. Approximately 20,000 people are diagnosed with AML in the United States each year, with the NPM1 genetic mutation found in approximately 30% of cases. Relapse in AML is common, and despite available treatments, nearly 11,000 people die from the disease each year in the United States.

About Measurable Residual Disease
Measurable residual disease (MRD) is a term that describes small numbers of leukemic cells that are still detectable during or after treatment, even when a patient has achieved complete response by standard criteria. Remaining leukemic cells in the body can become active and start to multiply, resulting in a relapse of the disease, which is fatal for most patients. Achieving MRD negativity, which is associated with longer remissions and improved survival, means that a treatment has reduced the number of leukemic cells to below the limit of detection by the most sensitive analytical methods. MRD can be detected using fluorescently labeled antibodies that recognize specific proteins on the surface of the leukemic cells (multi-parameter flow cytometry (MFC)) or by molecular methods such as DNA sequencing or polymerase chain reaction (PCR). Molecular methods are viewed as more sensitive and reliable than MFC, but require a unique mutation or DNA sequence that is only found in the leukemic cells. NPM1 mutations provide that unique sequence in patients with NPM1-mutated AML.

About Entospletinib
Kronos Bio is developing entospletinib for the frontline treatment of NPM1-mutated acute myeloid leukemia (AML). Entospletinib is a selective inhibitor targeting spleen tyrosine kinase (SYK), a critical node in a dysregulated transcription regulatory network within AML defined by persistent high expression of the transcription factors HOXA9 and MEIS1 (HOX/MEIS). Multiple AML driver mutations, including NPM1 and MLL gene rearrangements, have been associated with elevation of HOX/MEIS. Entospletinib has been investigated in more than 700 patients with a variety of hematologic malignancies, including AML, with clinical results observed in patients with AML who have NPM1 mutations and MLL rearrangements that support further development of the therapy.

Karyopharm Announces Dosing of First Patient in a New Phase 2 Study Evaluating Single-Agent Selinexor Versus Physician’s Choice in Previously Treated Myelofibrosis

On December 6, 2021 Karyopharm Therapeutics Inc. (Nasdaq:KPTI), a commercial-stage pharmaceutical company pioneering novel cancer therapies, reported dosing of the first patient in a new Phase 2 study evaluating oral selinexor, the Company’s first-in-class, oral Selective Inhibitor of Nuclear Export (SINE) compound, as a monotherapy versus physician’s choice in patients with myelofibrosis (MF) previously treated with a JAK 1/2 inhibitor (XPORT-MF-035; NCT04562870) (Press release, Karyopharm, DEC 6, 2021, View Source [SID1234596468]).

This randomized, multi-center, open-label Phase 2 study is designed to evaluate the safety and efficacy of selinexor monotherapy and is expected to enroll up to 112 patients, who will be randomized 1:1 to receive either low dose, once-weekly oral selinexor or physician’s standard treatment choice (per clinical practice). The primary endpoint of the study is the percentage of patients with spleen volume reduction (SVR) of ≥35% from baseline as assessed by an Independent Review Committee. The first patient has been dosed at the Instituto Scientifico Romagnolo per lo Studio e la Cura dei Tumori (IRST) Meldola, Italy, by the Lead Principal Investigator, Dr. Alessandro Lucchesi, Sr. Consultant and Research Hematologist under the guide of Professor Giovanni Martinelli, the Chief Scientific Director.

Initiation of this Phase 2 study follows encouraging preliminary data from the Phase 2 ESSENTIAL trial, which will be highlighted in an oral presentation given by Srinivas Tantravahi, MBBS, MRCP, University of Utah Hospital, at the upcoming American Society of Hematology (ASH) (Free ASH Whitepaper) 2021 Annual and Exposition on Saturday, December 11, 2021 at 1:00 p.m. ET. In the investigator-sponsored ESSENTIAL study (NCT03627403), which is evaluating selinexor in patients with MF previously treated with a JAK inhibitor, preliminary data showed that 33% of patients that received at least 24 weeks of selinexor treatment achieved ≥35% SVR. The responses were durable, and the first patient remained on study for more than two years. Patients had a median duration of 22 months of prior JAK inhibitor therapy with 11 out of 12 patients having disease refractory to ruxolitinib.

"As part of our strategic imperatives and pipeline priorities, we remain focused on diseases with the highest unmet needs and greatest potential to make an impact in patient outcomes," said Sharon Shacham, PhD, MBA, Co-Founder and Chief Scientific Officer of Karyopharm. "Myelofibrosis is a serious and life–threatening blood cancer defined by stem cell–derived clonal myeloproliferation, bone marrow fibrosis, anemia, enlarged spleen, low blood counts and short survival. With JAK inhibitors being the only class of drugs approved for this disease, there remains limited therapeutic options for patients who either progress following treatment with a JAK inhibitor or are intolerant. We believe selinexor has the potential to hold an important place in the myelofibrosis treatment paradigm and with dosing of the first patient underway, we plan to provide updates as the study progresses."

About XPOVIO (selinexor)

XPOVIO is a first-in-class, oral Selective Inhibitor of Nuclear Export (SINE) compound. XPOVIO functions by selectively binding to and inhibiting the nuclear export protein exportin 1 (XPO1, also called CRM1). XPOVIO blocks the nuclear export of tumor suppressor, growth regulatory and anti-inflammatory proteins, leading to accumulation of these proteins in the nucleus and enhancing their anti-cancer activity in the cell. The forced nuclear retention of these proteins can counteract a multitude of the oncogenic pathways that, unchecked, allow cancer cells with severe DNA damage to continue to grow and divide in an unrestrained fashion. Karyopharm received accelerated U.S. Food and Drug Administration (FDA) approval of XPOVIO in July 2019 in combination with dexamethasone for the treatment of adult patients with relapsed refractory multiple myeloma (RRMM) who have received at least four prior therapies and whose disease is refractory to at least two proteasome inhibitors, at least two immunomodulatory agents, and an anti-CD38 monoclonal antibody. NEXPOVIO (selinexor) has also been granted conditional marketing authorization for adult patients with heavily pretreated multiple myeloma by the European Commission. Karyopharm’s supplemental New Drug Application (sNDA) requesting an expansion of its indication to include the treatment for patients with multiple myeloma after at least one prior therapy was approved by the FDA on December 18, 2020. In June 2020, Karyopharm received accelerated FDA approval of XPOVIO for its second indication in adult patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL), not otherwise specified, including DLBCL arising from follicular lymphoma, after at least two lines of systemic therapy. Selinexor is also being evaluated in several other mid-and later-phase clinical trials across multiple cancer indications, including as a potential backbone therapy in combination with approved myeloma therapies (STOMP) and in endometrial cancer (SIENDO), among others. Additional Phase 1, Phase 2 and Phase 3 studies are ongoing or currently planned, including multiple studies in combination with approved therapies in a variety of tumor types to further inform Karyopharm’s clinical development priorities for selinexor. Additional clinical trial information for selinexor is available at www.clinicaltrials.gov.

FRESCO-2 is a randomized, double-blind, placebo-controlled, multicenter trial being conducted in patients with metastatic CRC. The primary endpoint of the study is overall survival ("OS"). This large Phase III trial enrolled patients in over 150 sites in 14 countries. Additional details of the study may be found at clinicaltrials.gov, using identifier NCT04322539.

Dr. Marek Kania, EVP, Managing Director and Chief Medical Officer of HUTCHMED International Corporation, said, "HUTCHMED continues to execute on developing novel oncology medicines for patients worldwide despite the backdrop of the global pandemic. We would like to thank investigators, patients and their families for taking part in this study and we look forward to seeing the results of this study in patients with metastatic CRC, where there is a high unmet need for new treatment options."

Topline results from the FRESCO-2 trial are expected to be reported in the second half of 2022 when the event-driven primary endpoint, OS, is mature. If positive, HUTCHMED would initiate plans to apply for marketing authorization of fruquintinib by the U.S. Food and Drug Administration ("FDA"), the European Medicines Agency ("EMA") and the Japanese Pharmaceuticals and Medical Devices Agency ("PMDA"). The U.S. FDA granted Fast Track Designation for the development of fruquintinib for the treatment of patients with metastatic CRC in June 2020. Clinical data from the completed Phase III FRESCO study in Chinese patients, additional supporting studies in CRC and this FRESCO-2 global study, if positive, could support a future U.S. FDA New Drug Application ("NDA") for the treatment of patients with advanced metastatic CRC (third-line and later). The FRESCO-2 study design was also reviewed and endorsed by the EMA and PMDA.

HUTCHMED retains all commercial rights to fruquintinib outside of China. In China, where fruquintinib is marketed under the brand name ELUNATE, HUTCHMED is partnered with Eli Lilly and Company and is responsible for development and execution of all on-the-ground medical detailing, promotion and local and regional marketing. Fruquintinib is not approved for use outside of China.

About CRC
CRC is a cancer that starts in either the colon or rectum. CRC is the third most common cancer worldwide, estimated to have caused more than 915,000 deaths in 2020.[2] In the U.S., an estimated 150,000 people will have been diagnosed with CRC and 53,000 people will have died from CRC in 2021.[3] In Europe, CRC is the second most common cancer, with an estimated 507,000 new cases and 240,000 deaths in 2020.2 In Japan, CRC is the most common cancer, with an estimated 147,000 new cases and 59,000 deaths in 2020.2

About Fruquintinib
Fruquintinib is a highly selective and potent oral inhibitor of VEGFR-1, -2 and -3. VEGFR inhibitors play a pivotal role in blocking tumor angiogenesis. Fruquintinib was designed to improve kinase selectivity to minimize off-target toxicities, improve tolerability and provide more consistent target coverage. The generally good tolerability in patients to date, along with fruquintinib’s low potential for drug-drug interaction based on preclinical assessment, suggests that it may also be highly suitable for combinations with other anti-cancer therapies.

About Fruquintinib Approval in China
Metastatic colorectal cancer in China: Fruquintinib was approved for marketing by the China National Medical Products Administration (NMPA) in September 2018 and commercially launched in China in late November 2018 under the brand name ELUNATE. It was included in the China National Reimbursement Drug List (NRDL) in January 2020. ELUNATE is indicated for the treatment of patients with metastatic CRC who have been previously treated with fluoropyrimidine, oxaliplatin and irinotecan, including those who have previously received anti-VEGF therapy and/or anti-EGFR therapy (RAS wild type). Results of the FRESCO study1, a Phase III pivotal registration trial of fruquintinib in 416 patients with metastatic CRC in China, were published in The Journal of the American Medical Association, JAMA, in June 2018 (clinicaltrials.gov identifier: NCT02314819).

About Fruquintinib Development Beyond CRC Monotherapy
The safety and efficacy of fruquintinib for the following investigational uses have not been established and there is no guarantee that it will receive health authority approval or become commercially available in any country for the uses being investigated:

Gastric Cancer ("GC") in China: In October 2017, HUTCHMED initiated the FRUTIGA study, a randomized, double-blind, Phase III trial evaluating the efficacy and safety of fruquintinib combined with paclitaxel for second-line treatment of advanced gastric or esophagogastric junction ("GEJ") adenocarcinoma. The trial is designed to enroll patients who did not respond to first-line standard chemotherapy. Subjects receive either fruquintinib combined with paclitaxel or placebo combined with paclitaxel. Patients are randomized at a 1:1 ratio and stratified according to factors such as stomach vs. GEJ tumor type and performance status. The primary efficacy endpoint is OS. Secondary efficacy endpoints include progression-free survival (as defined by RECIST 1.1), objective response rate, disease control rate, duration of response, and quality-of-life score (EORTC QLQ-C30, version 3.0). Biomarkers related to the antitumor activity of fruquintinib will also be explored (clinicaltrials.gov identifier: NCT03223376). In June 2020, HUTCHMED completed a planned interim data review. Based on the preset criteria, the Independent Data Monitoring Committee (IDMC) recommended that the trial continue.

Immunotherapy combinations: HUTCHMED has entered into collaboration agreements to evaluate the safety, tolerability and efficacy of fruquintinib in combination with PD-1 monoclonal antibodies, including with tislelizumab (BGB-A317, developed by BeiGene, Ltd) and sintilimab (IBI308, developed by Innovent Biologics, Inc. and marketed as TYVYT in China).

Metastatic breast and endometrial cancers in the U.S.: HUTCHMED initiated this open-label, multi-center, non-randomized, Phase Ib/II study in the U.S. to assess the safety and efficacy of fruquintinib in combination with tislelizumab in patients with advanced, refractory triple negative breast cancer ("TNBC") and endometrial cancer ("EMC"). This study is being conducted to investigate if the addition of fruquintinib can potentially induce activity to immune checkpoint inhibitor therapy in TNBC and EMC.
