The drugs still work.
The tumors stop responding.
We design peptides to restore the tumor’s response.

AecorBio is an IND-enabling peptide therapeutics company. Our orally active peptides normalize the dysregulated gene expressions that drive treatment resistance, restoring the effectiveness of standard-of-care medicines across oncology, immunology and neurology.

Lead Drug Candidate

A first-in-class oral peptide drug that targets the iron dysregulation behind treatment resistance in prostate cancer.

Our lead peptide normalizes the dysregulated prostate tumor labile iron pool — a validated but previously undruggable resistance mechanism — restoring the efficacy of the standard-of-care (SOC) androgen receptor pathway inhibitors (ARPI) for mCRPC patients.

Mode of Action

The Iron Gene Dysregulation Story

Androgen receptor pathway inhibitor (ARPI)-resistant prostate tumors accumulate toxic free iron, driven by dysregulation of the iron master regulatory gene — IREB2 (Iron Responsive Element Binding Protein 2).
Our lead drug product normalizes IREB2 expression to reduce free iron and successfully restore ARPI-mediated tumor control.

Our drug product normalizes IREB2
Normalizing the master gene addresses all three downstream genes (TFRC, FTH1, FPN) together, and the labile iron pool returns to normal.
Overcoming resistance safely
This targeted approach clears the excess free iron the tumor depends on to escape ARPI treatment—doing so without toxicity or disruption to systemic iron homeostasis.
Novel formulation
Novel Formulation

Peptide drugs are usually injected because gastric acid and digestive enzymes destroy them.
Our drug product is a novel oral formulation designed to survive gastric digestion.

The lead peptide is dispersed in polymerized alpha-lipoic acid (pALA) which is chemically stable in the stomach.
This biocompatible matrix completely depolymerizes only in the small intestine, releasing the peptide for systemic absorption.
ORAL CAPSULE STOMACH Matrix stays intact SMALL INTESTINE Payload released where peptide uptake is greatest ABSORPTION Systemic exposure achieved No cold chain needed No reconstitution; No injection; Lower cost of goods Separately patented Filed independently of the composition-of-matter estate

A sequential indication strategy — no approved therapy reverses ARPI resistance in any of these markets.

Our ARPI-combination mechanism opens three addressable markets in sequence, each mapped to the clinical plan: a first indication in metastatic disease, an earlier-line label expansion, and a pipeline indication that shares the same mechanism.
PHASE 1b · FIRST INDICATION
mCRPC

Metastatic castration-resistant prostate cancer on or after an ARPI — the initial clinical indication and fastest path to a signal.

~$8.3B
Non-metastatic (M0) CRPC, where ARPIs are already standard of care — an earlier line with longer treatment duration.

PIPELINE · ADJACENT INDICATION
Platinum-resistant ovarian

The same labile iron pool / IREB2 mechanism in a separate indication — roughly 60,000 cases per year across the 7MM.

Combined addressable market — Prostate CRPC (mCRPC + nmCRPC) grows from $13.0B to $21.4B by 2030 at 8.7% CAGR (Grand View Research), plus a ~$1.5B adjacent ovarian opportunity.
A bottom-up build (addressable patients × ARPI-combination share × annual net price) lands at ~$11B US and ~$21B global serviceable market.

Oncology franchise
The Oncology Franchise

One IND-enabling dossier unlocks a multi-cancer franchise.

In every cancer where iron dysregulation is a documented driver of resistance to standard of care, the IND-enabling dossier carries over unchanged: no new molecule, no new toxicology, no new manufacturing. Preclinical efficacy is the only new requirement, and once Phase 1b establishes human safety in mCRPC patients, each added indication is designed to move rapidly into Phase 2 on that same safety foundation.
One IND-enabling dossier supports the oncology franchise.

The platform
Novel Discovery Platform
AecorBio first validates a clinically viable pharmacodynamic biomarker by confirming gene expression dysregulation in accessible patient tissue. Peptide motifs active on that target are then discovered from large natural libraries generated by targeted proteome hydrolysis. Our mCRPC co-treatment program is the first to complete this discovery-to-clinical pipeline.

Beyond oncology
Beyond Oncology

Treatment resistance driven by dysregulated gene expression is not limited to cancer.

For eosinophilic asthma and restless legs syndrome, current standards of care lose efficacy as the expression of a critical target gene becomes dysregulated. Our discovery-stage platform identifies novel peptides designed to directly target and correct this underlying gene dysregulation.
