Immunic shares rise 10.70% intraday after European Patent Office grants key patent for vidofludimus calcium and Phase 3 trials for multiple sclerosis.

think> Okay, let's tackle this user query. They want me to transform a given text into a concise news headline following specific rules. First, I need to understand the input structure. The example provided shows that the output should include the company name, percentage change rounded to two decimals, time period, and a brief reason. Looking at the input text: "Immunic盘中 intraday大涨10.69767442%, 1、3月10日，欧洲专利局授予Immunic关键专利EP3713554，保护vidofludimus钙的标签相关剂量方案，保护期至2038年，并可能通过补充保护证书延长至2043年，增强核心资产知识产权保护。 2、2月26日，Immunic在年报中披露其作为生物技术公司，专注于开发用于神经和胃肠道疾病的新型口服疗法，主要产品vidofludimus钙IMU-838处于多发性硬化症的Phase 3临床试验阶段。 ，，）" First step: Identify the company name. It's "Immunic". The percentage is 10.69767442%, which rounds to 10.70%. The time period is intraday. Next, the reasons for the price movement are two points. The first is about the European Patent Office granting a key patent, protecting the drug's dosage regimen until 2038, possibly extended to 2043. The second point is about the company's focus on developing oral therapies for neurological and GI diseases, with the main product in Phase 3 trials for MS. The user's example combined both reasons into the brief explanation. So I need to mention the patent grant and the Phase 3 trial. Also, note that the patent is for vidofludimus calcium's label-related dosage, which is part of their core IP protection. The product is in Phase 3 for multiple sclerosis. I need to structure the headline to include all these elements concisely. The example used "surged" for the percentage change. Here, "doubled" might be too strong, but "surged" is appropriate for a 10.70% increase. Check the rounding: 10.69767442 rounds to 10.70, correct. The time period is intraday. Now, the brief reason should include the patent grant and the Phase 3 trial. The example combined both in one sentence, but maybe here it's better to split into two sentences for clarity. However, the user's example had two sentences, so maybe follow that structure. Also, the patent number EP3713554 should be included, but the example didn't include the patent number. Wait, in the example, they mentioned the project size (1.95MW) but not the patent number here. The user's instruction says to retain key information. The patent number is key, so maybe include it. But the example didn't include a patent number, so perhaps it's optional. Let me check the rules again. The rules say to provide a brief reason retaining key information. The patent number might be considered key, but the example omitted it. Hmm. In the example, the key info was the project in NYC. Here, the key info is the patent grant and the Phase 3 trial. The patent grant is important for IP protection, and the Phase 3 trial is about the drug's development stage. So, the headline should mention the patent grant by EPO and the Phase 3 trial. The patent's protection period is until 2038 with possible extension to 2043. The product is in Phase 3 for MS. Putting it all together: "Immunic surged 10.70% intraday as the European Patent Office granted a key patent (EP3713554) protecting the label-related dosage regimen of vidofludimus calcium until 2038 (extendable to 2043), bolstering core IP. The company, focused on developing oral therapies for neurological and gastrointestinal diseases, has its lead product, vidofludimus calcium (IMU-838), in Phase 3 trials for multiple sclerosis." Check the rules: company name is correct, percentage rounded to two decimals, time period is intraday, brief reason includes both the patent and the trial. The patent number is included, which is key. The product name and trial phase are mentioned. The company's focus is also included. The example had the company description at the end, so follow that structure. I think this meets all the requirements. Let me double-check the rounding again. 10.69767442 rounds to 10.70. Yes. Time period is intraday. The reasons.
