SEOUL, South Korea, April 30, 2025 ~ J INTS BIO, a leading company in the development of anticancer and orphan drugs, made significant announcements at the American Association for Cancer Research (AACR) 2025 conference in Chicago. The company presented its research findings on two promising treatments: 'JIN-A02', a next-generation EGFR-TKI therapeutic in clinical Phase 1/2 trials, and 'JIN-001', a potential treatment for ovarian cancer in preclinical stages.

The presentation by J INTS BIO attracted attention from both academia and the industry, showcasing the company's innovative drug development capabilities on a global stage. Professor Byoung Chul Cho from Yonsei Cancer Center presented a poster on the phase 1/2 clinical trial of 'JIN-A02', a next-generation oral EGFR-TKI.

'JIN-A02' has shown promising results in patients with non-small cell lung cancer (NSCLC), which accounts for 85% of all lung cancer cases worldwide. In particular, it has shown remarkable efficacy in patients who have developed resistance to existing third-generation EGFR-TKIs. This is significant as there are currently no approved targeted therapies for patients with EGFR C797S mutation. The drug also demonstrated excellent safety profile with no dose-limiting toxicities or serious adverse events observed up to the 300 mg dose.

In one patient from the 300 mg cohort, complete clearance of circulating tumor DNA (ctDNA) harboring either the C797S or Ex19del mutation was observed, and ctDNA carrying the T790M mutation was reduced by over 90%. Additionally, there was a partial response (PR) with tumor size reductions of up to 39.7%, including shrinkage of intracranial metastatic lesions. These results are particularly significant for NSCLC patients who often develop brain metastases.

Currently, 'JIN-A02' is undergoing multinational clinical trials in Korea, the United States, Thailand, and other countries. It is being closely monitored as a potential groundbreaking treatment option for EGFR-mutant NSCLC patients.

Another promising drug presented by J INTS BIO was 'JIN-001', a second-generation synthetic HSP90 inhibitor developed to overcome resistance to existing ovarian cancer treatments. Ovarian cancer is one of the deadliest gynecological malignancies, often diagnosed at an advanced stage with limited treatment options.

In preclinical studies, 'JIN-001' showed significant enhancement of tumor suppression when combined with the chemotherapeutic agent cisplatin compared to cisplatin alone. Even at low concentrations, it demonstrated enhanced antitumor activity against both cisplatin-sensitive and cisplatin-resistant ovarian cancer cells. The combination therapy also reduced the expression of key signaling proteins related to cisplatin resistance, leading to sustained antitumor effects.

Based on these promising results, J INTS BIO plans to conduct additional preclinical studies and move 'JIN-001' into clinical trials with the goal of establishing a new standard of care for refractory and multidrug-resistant ovarian cancer.

The company's presentation at AACR 2025 highlights its commitment to strengthening its position in the global oncology market and becoming a leader in next-generation anticancer drug development. J INTS BIO aims to continue delivering innovative therapies through ongoing research and development efforts, offering hope to cancer patients worldwide.
