BioNTech shares spiked after announcing a pivotal breast cancer trial success, but the rally proved short-lived as investors weighed approval risks and timelines.
A Surge That Couldn’t Hold
BioNTech SE (BNTX) briefly stole the spotlight on Friday as its stock jumped nearly 10% in pre-market trading, breaking through the $115 level for the first time in months. The excitement came after the company revealed encouraging late-stage trial results for an experimental breast cancer treatment developed in partnership with China’s Duality Biologics. However, the market got the idea that the establishment would postpone the release of the drug as much as possible.
So, despite the strong initial move, however, the rally soon unraveled. By Monday, shares had slipped back toward the $100 mark, erasing most of the earlier gains. A doji candlestick on Friday’s chart highlighted the sense of indecision in the market, suggesting that traders remain unconvinced about the near-term trajectory of the stock.

Breakthrough Trial Results
The source of the excitement was BioNTech’s antibody-drug conjugate (ADC), trastuzumab pamirtecan, which aims to deliver targeted cancer therapy with fewer side effects by binding directly to tumor cell proteins. In a pivotal late-stage trial involving patients with advanced breast cancer, the treatment achieved its primary endpoint of progression-free survival, outperforming Roche’s widely used ADC, trastuzumab emtansine. An independent data monitoring committee confirmed the strength of the results, lending credibility to the findings.
For BioNTech, this milestone is particularly significant. Chief Medical Officer Ozlem Tureci called the results a defining achievement, marking the first time one of the company’s late-stage oncology products has met its pivotal study objective. It represents a tangible step in BioNTech’s long-stated ambition to move beyond COVID-19 vaccines and build a sustainable oncology pipeline.
Path Toward Regulatory Approval
Following the successful trial, DualityBio plans to begin discussions with China’s National Medical Products Administration (NMPA) through the Center for Drug Evaluation (CDE) to explore filing an application for approval. Since the trial was conducted in China, the company is expected to seek Chinese regulatory clearance first before targeting broader global submissions. An approval in China would not only validate the therapy in one of the world’s largest healthcare markets but also strengthen BioNTech’s reputation as a serious contender in oncology.
Investor Sentiment and Outlook
Despite the clinical breakthrough, traders quickly tempered their optimism. The stock’s sharp retreat suggested that markets are already looking beyond the trial data toward the uncertainties of regulatory timelines and potential commercialization challenges. Approval is not guaranteed, and delays could weigh on sentiment in the months ahead. Still, the announcement underscores BioNTech’s ability to diversify its business model beyond its pandemic-era vaccine windfall, with oncology now at the forefront of its strategy.
The volatility also reflects broader questions facing biotech investors: while breakthrough therapies can dramatically alter a company’s prospects, regulatory hurdles and competition can just as easily temper enthusiasm. For BioNTech, the success of trastuzumab pamirtecan signals progress, but the journey from trial success to market reality remains complex.
