Medigen Biotechnology Corp (基亞生技) said it would continue to seek European partners to develop its new liver cancer drug, PI-88, after failing to yield positive results in a phase III clinical trial.
On Tuesday, Medigen said that among the 519 people taking part in the study, the 258 who were administered PI-88 did not produce a statistically significant improvement in disease-free survival against a control group of 261 who were given a placebo.
The outcome is the same as an interim study conducted by the company in 2014.
Despite the setback, the company said that the drug had shown more favorable results among people with microvascular invasion, a prognosis factor for liver cancer.
The company said that people with microvascular invasion accounted for 41 percent of those who participated in the study, and that the sub-group of patients had shown more favorable results that were close to meeting what is deemed statistically significant.
The study also showed that the drug had an acceptable safety profile in terms of side effects and toxicity, the company said.
The company will conduct further studies on the drug as a treatment for the specific sub-group of liver cancer patients with microvascular invasion, Medigen chairman Stanley Chang (張世忠) said.
Medigen shares yesterday tumbled for a second consecutive day, dropping 5.39 percent to NT$64.90, following a 10 percent fall on Wednesday.
China has claimed a breakthrough in developing homegrown chipmaking equipment, an important step in overcoming US sanctions designed to thwart Beijing’s semiconductor goals. State-linked organizations are advised to use a new laser-based immersion lithography machine with a resolution of 65 nanometers or better, the Chinese Ministry of Industry and Information Technology (MIIT) said in an announcement this month. Although the note does not specify the supplier, the spec marks a significant step up from the previous most advanced indigenous equipment — developed by Shanghai Micro Electronics Equipment Group Co (SMEE, 上海微電子) — which stood at about 90 nanometers. MIIT’s claimed advances last
ISSUES: Gogoro has been struggling with ballooning losses and was recently embroiled in alleged subsidy fraud, using Chinese-made components instead of locally made parts Gogoro Inc (睿能創意), the nation’s biggest electric scooter maker, yesterday said that its chairman and CEO Horace Luke (陸學森) has resigned amid chronic losses and probes into the company’s alleged involvement in subsidy fraud. The board of directors nominated Reuntex Group (潤泰集團) general counsel Tamon Tseng (曾夢達) as the company’s new chairman, Gogoro said in a statement. Ruentex is Gogoro’s biggest stakeholder.

EUROPE ON HOLD: Among a flurry of announcements, Intel said it would postpone new factories in Germany and Poland, but remains committed to its US expansion Intel Corp chief executive officer Pat Gelsinger has landed Amazon.com Inc’s Amazon Web Services (AWS) as a customer for the company’s manufacturing business, potentially bringing work to new plants under construction in the US and boosting his efforts to turn around the embattled chipmaker. Intel and AWS are to coinvest in a custom semiconductor for artificial intelligence computing — what is known as a fabric chip — in a “multiyear, multibillion-dollar framework,” Intel said in a statement on Monday. The work would rely on Intel’s 18A process, an advanced chipmaking technology. Intel shares rose more than 8 percent in late trading after the
Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) has appointed Rose Castanares, executive vice president of TSMC Arizona, as president of the subsidiary, which is responsible for carrying out massive investments by the Taiwanese tech giant in the US state, the company said in a statement yesterday. Castanares will succeed Brian Harrison as president of the Arizona subsidiary on Oct. 1 after the incumbent president steps down from the position with a transfer to the Arizona CEO office to serve as an advisor to TSMC Arizona’s chairman, the statement said. According to TSMC, Harrison is scheduled to retire on Dec. 31. Castanares joined TSMC in
