Agios Pharmaceuticals Announces Early Phase 1 Data Showing Clinical Activity of AG-120 as a Single Agent in Advanced Acute Myeloid Leukemia (AML)

On November 18, 2014 Agios Pharmaceuticals reported the first reported safety and clinical activity for AG-120 from the ongoing Phase 1 dose escalation study in patients with IDH1-mutant positive advanced hematologic malignancies, including acute myeloid leukemia (AML) (Press release Agios Pharmaceuticals, NOV 18, 2014, View Source;p=RssLanding&cat=news&id=1990940 [SID:1234500982]). Agios has exclusive U.S. development and commercial rights to AG-120, a first-in-class, oral, selective, potent inhibitor of the mutant IDH1 enzyme. Daniel Pollyea, M.D., clinical investigator at the University of Colorado School of Medicine, will present the data in a late-breaking oral presentation today at the 26th Annual EORTC-NCI-AACR (Free EORTC-NCI-AACR Whitepaper) Symposium on Molecular Targets and Cancer Therapeutics being held in Barcelona, Spain. The company will webcast an investor conference call from the symposium at 10:00 a.m. EST (4:00 p.m. CET) on Wednesday, November 19, 2014.

As of October 17, 2014, the ongoing Phase 1 trial for AG-120 had enrolled 17 patients with a documented IDH1 mutation whose cancer relapsed or failed to respond (refractory) to at least one prior treatment regimen. At the time of the data cut, 14 patients with relapsed and/or refractory AML were evaluable; three patients recently initiated therapy and were not evaluable.

The initial data showed investigator assessed objective responses in seven out of 14 evaluable patients, including four complete remissions, with responses observed across the four dose levels tested, and early evidence of durability. One additional patient remains stable on study. AG-120 was well tolerated, with the majority of adverse events reported as mild to moderate. The maximum tolerated dose has not yet been reached. One patient had a dose limiting toxicity of asymptomatic grade 3 QT prolongation at the highest dose tested to date, which improved to grade 1 after AG-120 dose reduction according to treatment protocol. This patient is in complete remission and remains on AG-120. AG-120 showed favorable drug exposure and pharmacokinetics at all doses tested and also substantially reduced plasma levels of the oncometabolite 2-hydroxyglutarate (2HG), which is produced by the mutant IDH1 protein, to the level observed in healthy volunteers. The mechanism of response is consistent with differentiation, as evidenced by the maturation of the leukemic cells into infection fighting white blood cells, or neutrophils. Based on these findings, the company plans to initiate multiple expansion cohorts in the first half of 2015.

"These data show very promising evidence of clinical activity for AG-120 in AML patients with an IDH1 mutation," said Chris Bowden, M.D., chief medical officer of Agios Pharmaceuticals. "Together with the data we reported from our ongoing Phase 1 study of AG-221 in advanced hematologic cancers, our lead investigational medicine and an IDH2-mutant inhibitor, we believe IDH inhibitors could potentially change the treatment paradigm for AML patients with these mutations. We look forward to moving rapidly into multiple expansion cohorts in the first half of 2015 to further characterize the potential of AG-120."

"We are highly encouraged to see the early favorable safety profile and clinical activity of AG-120, which includes four patients who achieved complete remission," said Dr. Pollyea. "For the first time in decades, we have the potential to offer certain AML patients an improved targeted treatment for this fatal disease that has historically had limited treatment options. I am hopeful that in the future we clinicians will be able to offer well tolerated and highly effective targeted therapies for our patients who have AML harboring an IDH mutation."

Patients in the ongoing Phase 1 trial have advanced AML whose cancer was refractory to available medical treatments or relapsed after treatment. The primary objectives of the Phase 1 trial are to determine the maximum tolerated dose (MTD) and the recommended dose for further study of AG-120. Secondary objectives include characterization of the safety profile, pharmacokinetics, pharmacodynamics and early anti-tumor activity. The trial uses an open-label, dose escalating design. Patients have been enrolled to date in four cohorts of AG-120 administered at 100 mg twice a day, 300 mg once a day, 500 mg once a day and 800 mg once a day. The median age of these patients is 73 (range 42-87).

Angiogenesis is correlated with disease progression and poor prognosis in many tumor types, such as colon, lung, breast and gastric cancers. VEGF and KDR (VEGFR2) are over-expressed in most malignant tumors, such as gastric, liver, NSCLC, ovarian, brain, colorectal, and breast cancers and their signaling is key regulator for tumor angiogenesis. Researchers from PharmAbcine have developed Tanibirumab, an anti-VEGFR2/KDR fully human monoclonal antibody to treat solid tumors. Tanibirumab binds KDR and blocks binding of VEGFR ligands, including VEGF-A, VEGF-C and VEGF-D. Consequently, Tanibirumab inhibits ligand-stimulated activation of KDR, therefore inhibits ligand-induced angiogenesis, proliferation, and migration of human endothelial cells.

Tanibirumab had demonstrated anti-angiogenic efficacy against several cancer types and shown cross-species cross reactivity in multiple preclinical animal models including breast cancer, glioblastoma (GBM), lung cancer, colon cancer, and hepatocellular carcinoma (HCC). In November 2011, an open-label, non-randomized, dose-escalating phase I trial began to assess the safety and pharmacokinetics of Tanibirumab, administered intravenously, in 26 patients in Korea with advanced or metastatic cancer. The trial was finished in November 2013, with good safety and efficacy results. A phase II study of Tanibirumab in GBM is being planned.

"We are pleased to collaborate with PharmAbcine and look forward to moving Tanibirumab into clinical trials in China," Dr. Jing Lou, President and CEO of 3SBio commented, "3SBio continues to seek opportunities to expand our biologics pipeline, especially novel mAb candidates for refractory or metastatic cancers and other unmet medical needs, particularly in 3SBio’s core therapeutic areas of oncology and nephrology."

"Tanibirumab is a drug candidate with great potential to treat malignant tumors," Dr. Jin-San Yoo, President and CEO of PharmAbcine commented, "3SBio is a well-established industry leader with long-term vision in the innovative biological field in China, which makes them an ideal partner for strategic collaborations. We are looking forward to working with 3SBio to maximize this opportunity and benefit tens of thousands of Chinese patients suffering for cancers and other severe diseases."

Each year, over 1 million patients are diagnosed with various types of cancer in China1.

Phase I Dose-Escalation Extension Study to Determine the Safety and Tolerability of Intratumoural Injection(s) of EBC-46

Cancer, head and neck; Cancer, melanoma; Cancer, skin
It is in a multi-centre, single-agent, open-label, Phase I dose-escalation extension study to evaluate the safety and tolerability of repeated administrations of EBC-46 in patients who have successfully completed the main protocol (QB46C-H01, ANZCTR Trial ID: ACTRN12614000685617) (Clinical trial, Trial ID:ACTRN12614001207606, ANZCTR, NOV 17, 2014, View Source [SID1234517424]).
Patients will undergo a screening visit up to 3 months after completing the QB46C-H01 study. Treatment will be a single dose administered via intratumoural injection with safety monitoring for 21 days. Patients will be required to return for follow up assessments on Day 2, Day 8 (plus or minus 1 day), Day 15 (plus or minus 1 day) and Day 22 (plus or minus 1 day). Treatments will continue no sooner than 1 week since the last injection and will conclude when disease progression or intolerance presents.
Patients will initially receive the same dose level as they received in QB46C-H01 (if tolerated) or lower (if not tolerated or there is less tumour mass requiring dosing). Lower doses will be considered for patients who experienced a dose limiting toxicity (DLT) or Grade > 3 adverse event (AE) in the QB46C-H01 study or if the tumour burden requires less EBC-46.
The dose may be escalated to a higher level if that higher dose level has been demonstrated to be well-tolerated in the QB46C-H01 study (based on the incidence and severity of AEs and DLTs in the QB46C-H01 study) as determined by the Safety Review Committee.
