Cautionary Note Regarding Forward Looking Statements

Statements contained under this Item 8.01 and in certain of the materials filed herewith regarding matters that are not historical facts are “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995, as amended. Because such statements are subject to risks and uncertainties, actual results may differ materially from those expressed or implied by such forward-looking statements. Such statements include, but are not limited to, statements about the initiation, timing, progress, results, and cost of the Company’s research and development programs and the Company’s current and future preclinical studies and clinical trials, including statements regarding the timing of initiation and completion of studies or trials and related preparatory work, the period during which the results of the trials will become available, and the Company’s research and development programs; statements regarding the Company’s expectations for an improved quality of life of patients after treatment with bel-sar and changes to the treatment paradigm for patients; the Company’s ability to efficiently develop existing product candidates and discover new product candidates; the Company’s ability to successfully manufacture its drug substances and product candidates for preclinical use, for clinical trials and on a larger scale for commercial use, if approved; the ability and willingness of the Company’s third-party strategic collaborators to continue research and development activities relating to the Company’s development candidates and product candidates; the Company’s ability to commercialize its products, if approved; the Company’s ability to obtain additional funding for its operations necessary to complete further development and commercialization of its product candidates; the Company’s ability to obtain and maintain regulatory approval of its product candidates; statements regarding the Company’s beliefs and expectations for the high unmet medical need for an effective local treatment in ocular and urologic oncology to preserve organ function; the size and growth potential of the markets for the Company’s product candidates, and the Company’s ability to serve those markets; the Company’s financial performance; the Company’s expected cash runway into the second half of 2028; and the implementation of the Company’s business model, including strategic plans for its business and product candidates.

Any forward-looking statements are neither promises nor guarantees, and investors should not place undue reliance on these forward-looking statements because they involve known and unknown risks, uncertainties, and other factors, many of which are beyond the Company’s control and which could cause actual results to differ materially from those expressed or implied by these forward-looking statements, including, without limitation, uncertainties inherent in clinical trials and in the availability and timing of data from ongoing clinical trials; the expected timing for submissions for regulatory approval or review by governmental authorities; the risk that the results of the Company’s preclinical and clinical trials may not be predictive of future results in connection with future clinical trials; the risk that early or interim data from ongoing clinical trials may not be predictive of final data from completed clinical trials; the risk that governmental authorities may disagree with the Company’s clinical trial designs, even where the Company has obtained agreement with governmental authorities on the design of such trials, such as the Phase 3 Special Protocol agreement with the U.S. Food and Drug Administration; whether the Company will receive regulatory approvals to conduct trials or to market products; whether the Company’s cash resources will be sufficient to fund its foreseeable and unforeseeable operating expenses and capital expenditure requirements; the Company’s ongoing and planned preclinical activities; and the Company’s ability to initiate, enroll, conduct or complete ongoing and planned clinical trials. These risks, uncertainties, and other factors include those risks and uncertainties described under the heading “Risk Factors” in the Company’s most recent Annual Report on Form 10-K and Quarterly Report on Form 10-Q filed with the U.S. Securities and Exchange Commission (“SEC”) and in subsequent filings made by the Company with the SEC, which are available on the SEC’s website at www.sec.gov. Except as required by law, the Company disclaims any intention or responsibility for updating or revising any forward-looking statements contained under this Item 8.01 or in the materials filed herewith in the event of new information, future developments or otherwise. These forward-looking statements are based on the Company’s current expectations and speak only as of the date hereof and no representations or warranties (express or implied) are made about the accuracy of any such forward-looking statements.
