MetaVia shares surge 12.76% premarket after positive Phase 1b trial results for DA-1726 show strong glycemic response and hepatic effects.

think> Okay, let's start by understanding the user's query. They want me to act as a financial analyst explaining a stock's price movement based on relevant news. The input is in Chinese, so I need to parse that correctly. First, the stock mentioned is MetaVia (MTVA), which had a premarket increase of 12.75720165%. I need to round that to two decimal places, so 12.76%. The trading period is premarket. Now, looking at the recent news events. The user provided a lot of content, but most of it seems to be from Yahoo Finance and doesn't contain specific news. The first news item is titled "MetaVia Inc. (MTVA) Latest Stock News & Headlines" but the content is just an error message: "Oops, something went wrong". The rest of the news are from PR Newswire and Zacks Small Cap Research. Looking at the relevant news for MTVA, the latest one is about positive results from a Phase 1b trial of DA-1726 in metabolic disease. Other recent news include a $9.3 million public offering, compliance with Nasdaq bid price, and presentations at conferences. I need to check which of these are relevant. The Phase 1b trial results seem directly related to the company's drug development, which is a positive development. The public offering and compliance are also relevant. However, the premarket surge is 12.76%, which is a significant jump. The most recent news before the premarket would be the Phase 1b trial results. Wait, the user's input lists the news in reverse chronological order. The latest news is from 11 days ago about the Phase 1b trial. The user's stock performance is current (as of January 30, 2026), so the news from 11 days ago might not be the cause. But looking at the news, the most recent one is from 16 days ago about the public offering. Hmm, maybe the user made a mistake in the dates? The stock's premarket price is on January 30, so the news from 11 days ago would be around January 19. That might not be the immediate cause. Wait, the user's example shows the news being recent. In the example, the news is about a project announced, which is recent. But in the given case, the latest news are older. The most recent news in the input is from 11 days ago (assuming the dates are correct). However, the stock's movement is on January 30. So there's a gap. The user might have intended the latest news to be from January 30, but the input shows dates like "11d ago" which would be January 19 if the current date is January 30. Given that, there's a possibility that the user intended the latest news to be relevant, but the dates don't align. However, the user's input includes a news item titled "MTVA: Positive Results for 48 mg Cohort in Phase 1b Trial of DA-1726…" from Zacks Small Cap Research 11 days ago. If that's the case, then the positive trial results could be the reason for the premarket surge. But wait, the user's input also includes other news like the $9.3 million public offering (16 days ago), which is also a positive. However, the most recent and impactful news would be the trial results. Since the stock is up 12.76% in premarket, the trial results are likely the main driver. I need to check if any of the news events are from the same day as the premarket trading. The user's input doesn't mention any news from January 30. The latest news is from 11 days ago, which is January 19. That seems too old to affect the premarket on January 30. However, maybe the user made a mistake in the date format. If the dates are in the format "11d ago" meaning 11 days before January 30, that would be January 19. But if the dates are "11d ago" as in 11 days after the event, that's unclear. Given the ambiguity, the best approach is to look for the most relevant and recent news in the provided data. The Phase 1b trial results are a significant positive for a biotech stock like MetaVia. The other news, such as the public offering, is also positive but might not be as impactful as new clinical trial data. Therefore, the key news is the Phase 1b trial results showing positive glycemic response and favorable safety profile. This would likely drive investor confidence, leading to a significant premarket increase. I need to confirm.
