eta advances in clinical trials may not achieve favorable results in later clinical trials, if any, or receive marketing approval. The research and development of drugs and biological products is extremely risky. Only a small percentage of product candidates that enter the development process ever receive marketing approval. Before obtaining marketing approval from regulatory authorities for the sale of Kineta’s product candidates, Kineta must conduct extensive clinical trials to demonstrate the safety and efficacy of the product candidates in humans. The outcome of clinical testing is uncertain. Kineta may face unforeseen challenges in its product candidate development strategy, and Kineta can provide no assurances that it will ultimately be successful in its current and future 107

clinical trials or that Kineta’s product candidates will be able to receive regulatory approval. The results of preclinical studies and early clinical trials of Kineta’s product candidates may not be predictive of the results of later-stage clinical trials. For example, it is not uncommon for product candidates to exhibit unforeseen safety or efficacy issues when tested in humans despite promising results in preclinical animal models. Future results of preclinical and clinical testing of Kineta’s product candidates are also less certain due to the novel and relatively untested nature of the approach of Kineta’s development platform. In general, clinical trial failure may result from a multitude of factors including flaws in study design, dose selection, patient enrollment criteria and failure to demonstrate favorable safety or efficacy traits. As such, failure in clinical trials can occur at any stage of testing. A number of companies in the biopharmaceutical industry, including immuno-oncology companies, have suffered setbacks in the advancement of clinical trials due to lack of efficacy or adverse safety profiles, notwithstanding promising results in earlier trials.

Interim, “topline,” and preliminary data from Kineta’s clinical trials that are announced or published from time to time may change as more patient data become available and are subject to audit and verification procedures that could result in material changes in the final data.

From time to time, Kineta may publicly disclose preliminary or topline data from its clinical trials, which are based on a preliminary analysis of then-available data, and the results and related findings and conclusions are subject to change following a more comprehensive review of the data related to the particular trial. Kineta also makes assumptions, estimations, calculations and conclusions as part of its analyses of data, and Kineta may not have received or had the opportunity to fully evaluate all data. As a result, the topline or preliminary results that Kineta reports may differ from future results of the same
