Daiichi Sankyo Co. Ltd.’s quizartinib met the primary endpoint of overall survival in the pivotal phase III Quantum-First study, which tested the addition of quizartinib to chemotherapy vs. chemotherapy alone for adults with newly diagnosed FLT3-ITD-positive acute myeloid leukemia (AML).
The “showdown” at the American Society of Clinical Oncology (ASCO) meeting foreseen by one analyst between breast cancer drugs from Gilead Sciences Inc. and Astrazeneca plc with partner Daiichi Sankyo Co. Ltd. didn’t quite materialize.
The “showdown” at the American Society of Clinical Oncology (ASCO) meeting foreseen by one analyst between breast cancer drugs from Gilead Sciences Inc. and Astrazeneca plc with partner Daiichi Sankyo Co. Ltd. didn’t quite materialize. Or the showdown happened, but turned out more nuanced than a one-to-one, high-noon gunfight on Main Street. Gilead ended considerable suspense June 4 by offering at ASCO phase III data from the Tropics-02 study with Trodelvy (sacituzumab govitecan), expectations for which already had grown lukewarm. Astrazeneca and Daiichi dazzled the next-day meeting with phase III data from the Destiny-Breast04 (DB04) study with Enhertu (fam-trastuzumab deruxtecan).
When, late last year, Daiichi Sankyo Co. Ltd. won breakthrough status from the FDA for HER3-targeting lung cancer prospect patritumab deruxtecan, Wall Street began taking stock of other candidates in the space. “The winning strategy to therapeutically target HER3 remains to be seen,” noted a recent paper in Clinical Cancer Research, “but HER3 is a promising drug target, and the era of drugging the ‘undruggables’ has already started.”
Top-line results of Daiichi Sankyo Co. Ltd.’s phase III Quantum-First study, testing the addition of quizartinib to chemotherapy vs. chemotherapy alone for adults with newly diagnosed FLT3-ITD positive acute myeloid leukemia (AML), found the combination therapy provided a “statistically significant and clinically meaningful improvement” in overall survival vs. standard treatment alone, meeting the trial’s primary endpoint, Ken Takeshita, global head of R&D at Daiichi Sankyo, told BioWorld.
The race for a Japan-made COVID-19 vaccine is heating up as players make progress with their trials. Daiichi Sankyo Co. Ltd. recently shared the results from its phase I/II trial for DS-5670, its mRNA vaccine. The mRNA vaccine candidate initiated studies in March 2021. The findings showed that in terms of immunogenicity, both neutralizing activity and IgG titer increased after the vaccination.
Astrazeneca plc and Daiichi Sankyo Co. Ltd. are pushing forward with a challenge to Roche Holding AG with breast cancer drug Enhertu (trastuzumab deruxtecan) after it demonstrated superiority over the Swiss firm’s Kadcyla (trastuzumab emtansine) in a head-to-head trial.

Daiichi Sankyo Co. Ltd. has received conditional approval from Japan’s Ministry of Health, Labour and Welfare (MHLW) for its oncolytic virus Delytact (teserpaturev) to treat malignant glioma.
HONG KONG – Daiichi Sankyo Co. Ltd. has won regulatory approval for Enhertu (trastuzumab deruxtecan) in Japan based on a pivotal phase II trial alone. The HER2-directed antibody-drug conjugate has been approved for the treatment of patients with HER2-positive unresectable advanced or recurrent gastric cancer that has progressed after chemotherapy.
