Cellectar shares rise 21.43% intraday as company presents 2026 strategic plans at Biotech Showcase and initiates Phase 1b trial for CLR 125 in triple-negative breast cancer.

think> Okay, so I need to transform this given text into a concise news headline following the provided rules. Let me start by reading through the input carefully. The company name is Cellectar, and the percentage change is 21.42857143%. I need to round that to two decimal places, which would be 21.43%. The time period mentioned is intraday. The reason for the price movement is related to the Biotech Showcase meeting in January 2026 where Cellectar will present their 2026 strategic plan, including a European conditional market license application in Q3 2026. Also, they're starting a Phase 1b study for CLR 125 in Q1 2026 for triple-negative breast cancer, with interim data expected mid-2026. First, I need to make sure the company name stays exactly as given. Then, the percentage rounded correctly. The time period is intraday, so that's straightforward. The reason should include both key points: the Biotech Showcase presentation and the Phase 1b study. I need to condense these into a brief reason without losing important details. Let me check the example to see how they structured it. In the example, they mentioned the subsidiary and the project details. Here, I should mention the conference and the two key initiatives. I should start with the company name, the percentage, the time period, then the reason. Let me try structuring it: "Cellectar surged 21.43% intraday, driven by its presentation at the 2026 Biotech Showcase, outlining a 2026 strategic plan including a Q3 2026 European conditional market license application and a planned Q1 2026 Phase 1b study for CLR 125 in triple-negative breast cancer, with interim data expected mid-2026." Wait, but the example has a line break after the first sentence. Maybe I need to split into two sentences for clarity. Let me check the example again. The example has the first sentence with the surge and reason, then a second sentence with more details. So maybe I should follow that structure. So the first sentence would be the surge with the reason, and the second sentence can elaborate on the company's focus. But in this case, the company's focus isn't mentioned in the input. The input only talks about the two initiatives. So perhaps the second part isn't needed here. Hmm, the example included a second sentence about the company's focus, but in this case, the input doesn't provide that information. The input only gives the two points about the Biotech Showcase and the Phase 1b study. So maybe I don't need to add anything else. Let me see the example again: The example's first sentence includes the surge and the reason, then a second sentence about the project details and a third about the company's focus. In this case, the input doesn't have a third part about the company's focus. So perhaps I can just have two sentences: the surge and the reasons. Wait, the user's example has three sentences. Let me check again. The example's output is: "Pineapple Energy Inc. surged 4.23% in premarket trading, with the company announcing that its SunAtion subsidiary has signed an agreement to construct a 1.95MW project in New York City. The company stated that the project will be installed on a large industrial building, with construction scheduled to begin in July and installation to be expedited./nThe company focuses on developing leading local and regional solar, storage, and energy services companies across the United States, primarily providing end-to-end products covering solar, battery storage, and grid services for homeowners and small businesses." So three sentences. The first is the surge and the announcement. The second gives more details on the project. The third is the company's focus. In the current input, there are two points: the Biotech Showcase and the Phase 1b study. So maybe I can structure it into two sentences, each covering one point. Let me try: "Cellectar surged 21.43% intraday, driven by its presentation at the 2026 Biotech Showcase, where the company will outline its 2026 strategic plan, including a Q3 2026 European conditional market license application. Additionally, Cellectar plans to initiate a Q1 2026 Phase 1b study for CLR 125 in triple-negative breast cancer, with interim data expected mid-2026." That seems to cover both reasons in two sentences. But maybe I can combine them into one sentence if possible. Let me see. The example combines the two reasons into the first sentence. Let me check the example's first sentence: it mentions the subsidiary signing an agreement. The second sentence gives more.
