Alvara Therapeutics

Developing small-molecule medicines for chronic kidney disease

Kidney DiseaseDrug DiscoveryTherapeutics

Chronic kidney disease gradually reduces the kidneys’ ability to filter blood and maintain the body’s balance. Oxidative stress and inflammation can contribute to tissue scarring and loss of function. Existing care can slow progression, but patients still face kidney failure and cardiovascular complications.

Alvara Therapeutics is developing small molecules for chronic kidney disease. Its compounds target the interaction, aiming to activate the body’s antioxidant and anti-inflammatory responses and protect kidney tissue from ongoing damage.

Key Investor Signals

Secured a place in BII’s €560,000 loan cohort

Alvara joined ’s September 2026 cohort, whose participants are each allocated a €560,000 convertible loan plus venture-development support.

Translated 11 years of Keap1 research into a venture

Co-founder Anders Bach’s Copenhagen group developed the Keap1 program over 11 years before spinning it into Alvara with medicinal chemist Marie Cadot.

Developed several cell-active Keap1 inhibitor series

The SPARK Denmark project describes multiple novel inhibitor series with high affinity, selectivity, cellular activity and drug-like properties for further kidney-disease work.

Other Positive Signals

  • Built the research program with academic collaborators and contributions from AstraZeneca in Sweden.

Team

Marie Cadot

CEO and Co-founder

  • Completed a Copenhagen PhD on structure-guided, fragment-derived Keap1 inhibitors, directly matching the company’s target.
  • Trained as a pharmacist and medicinal chemist, with postdoctoral drug-design research at the University of Copenhagen.
  • Completed a 2020 R&D internship at Novo Nordisk Pharmatech, developing synthesis and characterization methods.

Anders Bach

CSO and Co-founder

  • Professor and group leader in at the University of Copenhagen, focused on disease-related protein interactions.
  • Built an 11-year Keap1 research program, developing compound series that underpin the Alvara spinout.
  • Developed fragment-based approaches and comparative assays to distinguish active Keap1 inhibitors from false-positive compounds.

Product

Alvara uses to build small-molecule inhibitors of Keap1–Nrf2. Small chemical fragments are screened for binding, examined structurally and developed into more potent compounds, with oral treatment as the intended product format.

Finding small chemical starting points

The discovery workflow screens libraries of low-complexity molecular fragments against the target. Sensitive biophysical methods identify weak binding that can provide a starting point for medicinal chemistry.

Using structure to improve compounds

Structural biology shows how each fragment sits in a protein pocket. The team uses that information to decide where to grow or link fragments, improving binding and other properties needed in a medicine.

Releasing a protective cellular response

The compounds are intended to disrupt Keap1’s interaction with Nrf2 without forming a permanent chemical bond. This can activate antioxidant and anti-inflammatory proteins, the biological rationale for kidney protection.

Market Overview

Chronic kidney disease creates a long-term treatment need across a large adult population, often alongside diabetes, hypertension and cardiovascular disease. Earlier-stage patients account for most cases. Drug development focuses on preserving kidney function before patients require dialysis or transplantation.

Renal medicine has attracted pharmaceutical acquisitions of both small-molecule and antibody developers. Alvara’s opportunity is a new protective mechanism within this established treatment field. A commercial program must show benefit beyond current care, with evidence on kidney function, progression and tolerability.

Annual deaths from chronic kidney disease
1.48M

Chronic kidney disease caused an estimated 1.48 million deaths globally in 2023.

Cardiovascular deaths linked to kidney function
11.5%

Impaired kidney function accounted for an estimated 11.5% of cardiovascular deaths in 2023.

Adult prevalence of stage 1–3 kidney disease
13.9%

The combined global prevalence of stage 1–3 chronic kidney disease was 13.9% among adults in 2023.
