ALTA2618: Ushering in the precision era for AKT-targeted therapies

ALTA2618 is a clinical-stage, first-in-class, mutation-specific inhibitor of AKT1 E17K, a key driver mutation present in up to 90% of AKT-activated cancers. Engineered for selectivity, potency, and a broad therapeutic index, ALTA2618 is designed to overcome the safety and efficacy limitations of pan-AKT inhibitors. By targeting the mutant protein while sparing wild-type AKT isoforms, indication-agnostic ALTA2618 is intended to deliver more durable and tolerable responses across a range of solid tumors.

ALTA2618 targets the disease-driving AKT1 E17K mutation while sparing wild-type AKT

ALTA2618’s mechanism of action – targets the disease-driving AKT1 E17K mutation while sparing wild-type AKT
Covalent binding to AKT1 and mutant selectivity could potentially allow for lower efficacious doses and a more favorable tolerability profile.
ALTA2618 incorporates multiple layers of precision engineering to potentially overcome the safety and efficacy limitations of earlier AKT inhibitors:
  • AKT1 isoform specificity – Designed to eliminate AKT2-driven toxicities (e.g. hyperglycemia)
  • Allosteric inhibition – May reduce the need to compete with ATP at the kinase active site, potentially lowering the efficacious dose
  • AKT1 E17K mutation specificity intended to spare wild-type AKT1 – May mitigate on-target toxicity and improve tolerability; may also improve the therapeutic index and reduce systemic side effects based on preclinical models
  • Covalent capture of the mutant lysine (E17K) – Designed to lock AKT1 in a closed, inactive conformation to suppress oncogenic signaling
  • Enhanced target coverage – Shown preclinically to drive stronger, more durable responses, which may translate to higher overall response rates across solid tumor types

AKTive-001 clinical trial

This Phase 1/1b clinical trial, looking at the safety and tolerability of ALTA2618, is enrolling adults with advanced solid tumors with an AKT1 E17K mutation.

The promise of pan-KRAS and ALTA3263

ALTA3263 is our first- and best-in-class candidate designed for broad, durable, and tolerable inhibition of KRAS-driven cancers. Developed to address the limitations of mutation-specific and pan-RAS inhibitors, ALTA3263 combines deep target coverage with a superior therapeutic index.

ALTA3263 offers:
  • KRAS isoform selectivity – Targets KRAS while sparing HRAS and NRAS, aiming to reduce off-target toxicities and support more tolerable, combinable treatment regimens
  • Broad KRAS mutant and wild-type (WT) coverage – Demonstrated <1nM potency across >90% of KRAS mutations, including common drivers (e.g., G12D, G12V) and resistance-associated variants. Targets WT KRAS to shut down compensatory signaling and help prevent therapeutic escape
  • Dual ON/OFF-state inhibition – Engineered to bind KRAS in both active (ON) and inactive (OFF) states, enabling inhibition of mutations like G12D and G12V that favor the ON state and are historically difficult to drug
  • Drug-like properties and pharmacokinetics profile – Designed for excellent oral bioavailability and pharmacokinetics, with the potential to achieve full, sustained target coverage and support monotherapy or combination use
  • Tolerability and combinability – Intended to deliver meaningful clinical activity without compromising safety, offering a promising therapeutic backbone for use in combination with standard-of-care or emerging targeted therapies
ALTA3263 inhibits both ON and OFF states
ALTA3263’s mechanism of action – inhibits KRAS in both ON and OFF states
Most KRAS inhibitors do not potently bind the ON state (as seen in preclinical models), which limits their ability to inhibit mutations like G12D and G12V that stay in the ON state longer.

Phase 1 clinical trial

We are currently enrolling people with advanced solid tumors with KRAS mutations into a Phase 1 study evaluating the safety, tolerability, pharmacokinetics, and preliminary clinical activity of ALTA3263.
