J INTS BIO's Novel Oral 4th Generation EGFR-TKI 'JIN-A02' effective against both cis and trans isomers of C797S mutations - ESMO 2022

SEOUL, South Korea, Sept. 15, 2022 /PRNewswire/ -- J INTS BIO announced the poster presentation of its novel, orally administered 4th generation EGFR-TKI 'JIN-A02' at the ESMO 2022, that showed high potency of JIN-A02 against both cis and trans isomers of C797S mutation. This year's edition of the European Society for Medical Oncology Congress (ESMO 2022) was held in Paris, France from 9^th to 13^th September.

Even though EGFR-TKI have improved treatment outcomes of patients with EGFR mutant NSCLC, resistance inevitably emerges with disease progression and often with CNS metastasis. C797S mutation is one of the most common on-target resistance mutation after the use of 3rd generation TKIs such as Osimertinib. 'JIN-A02' is a novel 4th generation EGFR-TKI, which is highly selective and potent against C797S double and triple mutations, with high BBB penetrance and intracranial efficacy.

The allelic context in which this C797S mutation is acquired, cis or trans isomers, have significant implications for treatment outcomes. This is especially so when C797S positive tumor are in cis form together with T790M mutation. In such situations, there are no available treatments.

J INTS BIO believes that JIN-A02 will be pivotal in the treatment of patients with EGFR mutant NSCLC harboring C797S double or triple mutations, regardless of allelic context. And the company is expecting the Phase I/IIa clinical study for JIN-A02 to start recruitment before the end of this year.

About 'JIN-A02'

'JIN-A02' is a novel orally administered 4th Generation EGFR TKI targeting C797S mutations in NSCLC. Although 1st, 2nd, and 3rd Generation EGFR TKIs have been used with some success, recurrence occurs in most patients including 3rd Generation TKIs such as Osimertinib. Currently, there are no approved therapies for patients who developed EGFR C797S mutations due to the use of 3rd Generation EGFR TKIs and with the high propensity of these cancers to metastasize to the brain, there is an urgent need to develop an effective drug with high blood-brain barrier permeability. 'JIN-A02', a novel oral EGFR TKI, which is effective against C797S double and triple mutations and have a high brain penetrance, is therefore expected to become the most promising Best-in-Class 4th-generation EGFR TKI in NSCLC patients with limited or no viable treatment options.
