KAT6 Inhibitors Overview
Lysine acetyltransferases (KATs) are epigenetic enzymes that regulate gene expression by modifying histone proteins, and have emerged as important targets in cancer therapy due to their frequent dysregulation through mutations, amplifications, or chromosomal translocations. Among them, KAT6A and KAT6B members of the MYST family play a pivotal role in acetylating histone H3 at lysine 23 (H3K23), facilitating chromatin remodeling and transcriptional activation. These enzymes operate as part of a tetrameric complex with chromatin-associated proteins like BRPF1, ING4/5, and EAF6, and are essential for biological processes such as embryonic development, cellular senescence, hematopoietic stem cell maintenance, and gene transcription. In cancer, KAT6A/B alterations can lead to widespread changes in histone acetylation and gene expression, including the activation of oncogenes or repression of tumor suppressor genes. Additionally, they act as coactivators for oncogenic transcription factors, further contributing to tumor progression. Given their central role in cancer biology, KAT6A and KAT6B are being actively explored as therapeutic targets, with several small-molecule inhibitors under development that specifically block their enzymatic or bromodomain functions.

KAT6 Inhibitors Emerging Drugs
PF-07248144: Pfizer
PF-07248144 is a selective catalytic inhibitor of KAT6, a histone lysine acetyltransferase. It is currently in Phase I of the development for the treatment of advanced or metastatic ER+ HER2- breast cancer, CRPC, and NSCLC.
In April 2025, at the American Society of Clinical Oncology (ASCO) Annual Meeting, Pfizer presented a rapid oral session featuring dose-optimization results from its ongoing Phase I trial of PF-07248144 in patients with ER+/HER2- metastatic breast cancer. These results supported the recommended dosing for PF-07248144 paving the way for a pivotal trial of KAT6i plus fulvestrant in second-line and later ER+/HER2- metastatic breast cancer, set to begin in the second half of 2025.
MEN2312: Stemline Therapeutics (Menarini Group)
MEN2312 is a potent and selective orally bioavailable KAT6A/B inhibitor. MEN2312 blocks the estrogen receptor at the transcriptional level, giving it the potential to overcome resistance to endocrine therapies due to mutation or ligand-independent constitutive activation of the estrogen receptor. MEN2312 is being investigated as a single agent and in combination with SoC in metastatic breast cancer ER+/HER- patients.
In January 2024, Stemline Therapeutics, a wholly-owned subsidiary of the Menarini Group, along with Insilico Medicine, announced that they have entered into an exclusive licensing agreement granted Stemline the global rights to develop and commercialize a novel, small molecule KAT6A inhibitor designed using Insilico's AI platform, as a potential treatment for hormone sensitive cancers and other oncology indications.

The market outlook for KAT6 inhibitors is gaining momentum, driven by growing interest in epigenetic targets and the recognition of KAT6A/B as key regulators in cancer progression. These enzymes are frequently dysregulated in various malignancies, making them attractive candidates for targeted therapy. KAT6 inhibitors are being explored primarily for their ability to modulate oncogenic gene expression, induce cellular senescence, and suppress tumor growth, especially in cancers with aberrant acetylation profiles. While still in the early stages of clinical development, the pipeline for KAT6 inhibitors is beginning to take shape. Some notable candidates in development include PF-07248144 (Pfizer), MEN2312 (Stemline Therapeutics), and OP-3136 (Olema Pharmaceuticals), all of which are progressing through early clinical stages. These agents reflect the industry's growing investment in targeting lysine acetyltransferases for precision oncology.
Despite the therapeutic promise, the current KAT6 pipeline remains relatively limited, with only a few compounds advancing to human trials. This underscores the need for continued research and innovation to expand and validate the potential of this drug class. Several biopharmaceutical companies are actively investing in this space, signaling a shift in focus toward epigenetic modulation as a viable and potentially transformative cancer treatment strategy. Overall, KAT6 inhibitors represent an emerging and exciting area of oncology drug development, with strong scientific rationale and early data supporting their use across multiple cancer types. With further clinical progress and strategic partnerships, this class has the potential to reshape the future of targeted cancer therapy.
This section focuses on the uptake rate of potential emerging KAT6 inhibitors expected to be launched in the market during 2025-2040.
