How I Protect My Peace While Living With Metastatic Breast Cancer
A month after my annual physical, I found a lump in my breast. I was initially diagnosed with stage 3 triple-negative breast cancer (a rare type that lacks receptors for estrogen, progesterone, and the HER2 protein, which makes certain treatments like hormone therapy ineffective). I was 29, so this diagnosis felt shocking—just totally out of left field. I was not worried it was cancer when I first found the lump; the thought didn’t even occur to me.

Alterations in the AKT pathway are common in cancer, with the AKT1 E17K mutation found in ~5% of HR+/HER2-negative breast cancers. Our drug, ALTA2618, is designed to selectively target AKT1 E17K, while sparing other AKT isoforms to enhance tolerability without compromising efficacy.
