What we do

Two problems. One molecule.

NB2 — a Coupled Anti-Infective Immunomodulatory Therapeutic — pairs direct antimicrobial action with built-in anti-inflammatory effect in a single new chemical entity.

Broad-spectrum potency

µg/mL activity against more than forty bacterial organisms — including AD-driving S. aureus and DFU-implicated strains — plus enveloped viruses such as SARS-CoV-2 and influenza.

Resistance-resilient

52 weeks of continuous passage at 50% of the MBC against S. aureus MN8 produced no observed resistance development — a property of the chemical class.

Dual mechanism by design

Anti-infective and immunomodulatory action coupled in the same molecule — not delivered as a combination. Toxin synthesis shut down at 1/15 of MBC.

Where we are

From bench to first-in-human.

A pre-IND meeting was completed with FDA Dermatology in May 2024 on the lead atopic dermatitis program. A parallel DFU pre-IND meeting is planned post-financing close.

Our Science

The CAIT class & NB2.

CAIT — Coupled Anti-Infective Immunomodulatory Therapeutic — is a proprietary chemical class invented at Niche. NB2 is a lipase-resistant analogue of glycerol monolaurate (GML), the antimicrobial scaffold in human breast milk.

The Compound

NB2 — a new chemical entity.

NB2 is classified as a new chemical entity per FDA regulations, qualifying for 5-year NCE exclusivity at approval. It is structurally optimized from glycerol monolaurate (GML) — the antimicrobial scaffold in human breast milk — to be fully lipase-resistant.

Mechanism

Two problems, one molecule.

01

Direct antimicrobial activity

µg/mL bactericidal potency against more than 40 bacterial organisms. Activity extends to enveloped viruses including SARS-CoV-2 and influenza.

02

Coupled anti-inflammatory effect

Toxin production (TSST-1 and other superantigens) is shut down at sub-MBC levels — addressing the inflammatory driver of disease in tandem with infection. Built into the same molecule, not delivered as a combination.

03

Resistance-resilient by design

Lipase resistance combined with multi-target action limits bacterial escape pathways. The 52-week no-resistance result is a property of the chemical class, applicable across S. aureus-driven indications.

The Headline Result

52 weeks. No resistance.

Antimicrobial resistance is the dominant failure mode in anti-infective drug development. NB2's chemical class did not select for resistance under continuous selective pressure — a foundational property that motivates both lead indications.

COMPARATOR ↑ resistant NB2 — flat WK 0 WK 13 WK 26 WK 39 WK 52 16× 64× ≥256× FOLD-CHANGE IN MBC

Compounds in the CAIT class were cultured continuously at 50% of the minimum bactericidal concentration — a pressure regime designed to select for resistant survivors. Over 52 weeks the bacteria did not develop resistance.

This is not a single-organism result; it is a property of the chemical class. MRSA panel expansion is planned in Year 1 to confirm class-level validation across clinical isolates.

A resistance-resilient antimicrobial that also resolves inflammation — in one molecule — is what the field has wanted for a generation.

In vivo & tox

10⁹-fold S. aureus reduction.

In the validated rabbit AD model, NB2 produced a 10⁵-fold S. aureus reduction at 4 hours and a 10⁹-fold reduction at 8 hours, with clear time- and dose-dependent response across 15 and 30 mg/mL doses.

The minipig dermal tox study (completed February 2025) established NOAEL at 25 mg/kg BID over 7 days at 10% BSA, with plasma exposure of 2–6 ng/mL and no accumulation. Top proposed clinical dose: 15 mg/mL — well below NOAEL margin.

Why NB2 should work

01 · Pathogen

S. aureus drives DFU

The majority of DFUs are infected with S. aureus producing superantigens (Schlievert lab, JID 2014).

02 · Healing block

Superantigens block healing

Demonstrated in vitro and in vivo (Schlievert lab, Biochemistry 2015). Until S. aureus and its superantigens are cleared, the wound does not close.

03 · NB2 does both

The two-pronged action

NB2 kills S. aureus and inhibits superantigen synthesis at sub-MBC — the exact mechanism DFU requires.

Standard of care
Debridement + offloading + systemic antibiotics — no effective topical breakthrough therapy
