Executive Summary

ELOX delivered a smaller net loss of $3.6M ($1.31 per share) in Q3 2023 as operating expenses continued to decline; the quarter was pre-revenue and costs were driven by R&D and G&A .
Clinical momentum: in Alport Syndrome, ELX-02 showed disease-modifying signals with an average 60% improvement in podocyte foot process effacement and post-treatment collagen expression observed in all three patients; data featured at ASN Kidney Week 2023 .
Liquidity remains the key overhang: cash was $4.8M at quarter-end; management raised ~$3.8M gross in Q3 and expects cash to fund operations only through end of Q4 2023 while pursuing additional capital .
Strategic update: progress toward a partnership for ZKN-013 following FDA clearance to begin a SAD study; discussions may enable focus on ELX-02 and continued funded discovery on TURBO‑ZM .
Listing risk: trading on Nasdaq is suspended pending appeal; shares began trading on OTC Pink as of Oct 16, 2023—an incremental investor access/visibility headwind .

What Went Well and What Went Wrong

What Went Well

ELX-02 Phase 2 Alport study showed structural kidney improvements: average 60% improvement in filtration slit density and protein re‑expression (COL4A5) post-treatment; independent TEM visual assessments confirmed foot process improvement; data included at ASN 2023 .
Cost discipline: R&D down to $1.3M (vs $4.9M prior year), reflecting lower CF and CFF-funded activities and reduced personnel/overhead; net loss narrowed to $3.6M (vs $7.5M prior year) .
CEO tone constructive on pipeline and partnering: “We are excited about the recent progress across our pipeline and remain committed to advancing our programs…” .

What Went Wrong

Liquidity runway limited: $4.8M cash at 9/30/23 with stated runway only through end of Q4 2023 absent additional funding; reliance on capital markets persists .
Listing status: Nasdaq trading suspended; shares moved to OTC Pink pending appeal—likely to constrain liquidity and widen spreads .
Program timing risk: ELX‑02 pivotal initiation is contingent on financing; ZKN‑013 pivoted to strategic transaction discussions vs immediate clinical initiation, introducing partner/timing uncertainty .

Estimates Context

S&P Global consensus estimates for Q3 2023 (EPS, revenue) were unavailable for ELOX via our estimates tool due to missing mapping; therefore, no comparison to Wall Street consensus can be provided for this quarter. As such, we do not present estimate vs actual comparisons for EPS or revenue in Q3 2023.

Key Takeaways for Investors

Clinical signal strengthening for ELX‑02 in Alport Syndrome, with structural kidney improvements and protein re‑expression across all treated patients; this underpins an emerging pivotal thesis and potential BTD pathway .
Liquidity is the gating factor: cash funds operations only through end of Q4 2023; additional financing or partnering is essential to enable a pivotal trial start and broader pipeline execution .
Strategic focus sharpening: ZKN‑013 likely to transition under a partner, freeing resources for ELX‑02 and TURBO‑ZM discovery; monitor timing and economics of any transaction .
Listing overhang: OTC Pink trading status and Nasdaq suspension may suppress liquidity and institutional participation; appeal outcome is a potential catalyst but also a risk .
Cost base flexing lower: sustained reductions in R&D and controlled G&A narrowed losses; however, absolute scale remains dependent on trial initiation pacing and financing .
Near‑term catalysts: FDA alignment on pivotal design/BTD for ELX‑02; potential ZKN‑013 partnering announcement; financing updates .
Trading implications: headlines around financing, partnering, or regulatory designations likely to drive outsized moves given micro‑cap/OTC dynamics and the binary nature of pivotal initiation readiness .
