Clene has received FDA approval to hold an in-person Type C meeting

[3]. This is a key regulatory milestone following constructive communications with the FDA in June 2025.

1. ✅ Determined the clinical significance of NfL reduction following CNM-Au8 treatment
2. ✅ Confirmed the reproducibility of NfL reduction in the HEALEY platform trial
3. ✅ Established the correlation between NfL reduction and clinical outcomes including survival

Analysis Dimension	Data Result	Statistical Significance
HEALEY Trial 24 Weeks	Geometric Mean Ratio (GMR)=0.905	p=0.0403
NIH-EAP Cohort 36 Weeks	AUC Difference=-0.090	p=0.0373
Mortality Risk Correlation	Mortality risk in the highest NfL slope group is 2.3-2.6x that of the lowest slope group	p<0.001

In two large, independent ALS cohorts (APST, Answer ALS), longitudinal increases in NfL levels are associated with with increased mortality risk, independent of baseline NfL levels and clinical covariates [3].

• Statistically significant reduction during the double-blind phase of the HEALEY trial (p<0.05)
• Highly correlated with changes in NfL (Pearson correlation coefficient r>0.85, p<0.0001)
• High GFAP levels are associated with increased mortality risk in ALS patients
• NfL and GFAP levels increased in the placebo group during the double-blind phase, while they decreased in the CNM-Au8 group

Population	1-Year Cox Hazard Ratio	95% Confidence Interval	Mortality Risk Reduction
Full Analysis Set (FAS)	0.2723	0.0961-0.7719	73%
Risk-Balanced Set (CRS)	0.229	0.07-0.752	77%

Restricted Mean Survival Time (RMST) was significantly extended by at 1 year post-treatment (95%CI: 7.52-53.85, p=0.0094) [4].

• Insulin-like Growth Factor Binding Protein 7 (IGFBP7) was identified as a novel pharmacodynamic biomarker from the HEALEY trial
• Defined responders as those with reduced cumulative AUC of IGFBP7 during the 24-week double-blind phase
• 78% reduction in mortality risk
  compared to the randomized control group (HR: 0.22, 95% CI: 0.07–0.71, p=0.012)
• IGFBP7 is a “mechanistic hub” coordinating biomarker responses, and is significantly correlated with multiple disease-related biomarkers

(Biogen/Ionis) received FDA accelerated approval in 2023, based on NfL as a “reasonable surrogate endpoint” [5]. This provides a clear regulatory pathway reference for CNM-Au8.

• Mechanistic link between NfL and neuronal injury
• Prognostic value of NfL in ALS (meta-analysis and regression analysis)
• Correlation analysis between NfL changes and ALSFRS-R score decline
• Causal inference analysis demonstrating the relationship between NfL changes and reduced functional decline

Factor	Detailed Analysis
Biomarker Data	Dual achievement of NfL and GFAP endpoints, with strong correlation to survival benefits
Regulatory Precedent	Tofersen has validated NfL as a surrogate endpoint for accelerated approval
FDA Interactions	Completed all required analyses per the FDA’s “roadmap”
Safety	Over 1,000 patient-years of exposure, no drug-related serious adverse events
Confirmatory Trial Preparation	Phase 3 RESTORE-ALS trial is planned as a post-marketing confirmatory study
Funding Security	Newly raised capital supports operations through Q3 2026

Timeframe	Milestone
Q1 2026	FDA In-Person Type C Meeting
Q1 2026	Planned NDA Submission
TBD	Initiation of Phase 3 RESTORE-ALS Trial (Confirmatory Study)
Post-Commercialization	RESTORE-ALS results used for full approval application

Risk Type	Risk Description	Mitigating Factors
Approval Uncertainty	The FDA may require additional data or endpoint adjustments	Multiple rounds of constructive communications with the FDA have been conducted
Confirmatory Trial Risk	RESTORE-ALS may miss endpoints	Well-planned, supported by robust biomarker data
Timeline Delays	The meeting may delay the NDA timeline	Direct financing provides sufficient time buffer
Data Interpretation Divergence	The FDA’s interpretation of clinical significance may differ from the company’s	Cross-validation with multiple independent data sources

Drug	Company	Type	Features
RILUTEK	Multiple Generic Drug Manufacturers	Disease-Modifying	Approved in 1995, limited efficacy
RADICAVA	Mitsubishi Tanabe	Disease-Modifying	Approved in 2017, IV/oral formulations
QALSODY	Biogen/Ionis	Disease-Modifying	Approved in 2023 via accelerated approval based on NfL
NUEDEXTA	Avanir/Otsuka	Symptomatic	Treats pseudobulbar palsy

1. Oral Formulation
   : Unlike RADICAVA’s IV formulation and QALSODY’s intrathecal injection, CNM-Au8 is administered orally, significantly improving patient compliance
2. Unique Mechanism
   : Gold nanocrystals target mitochondrial function, differing from the mechanisms of existing therapies
3. Survival Benefit
   : Demonstrates significant mortality risk reduction (73-77%)
4. Safety Advantage
   : Over 1,000 patient-years of exposure with no major safety concerns

~$28-32 per share, consistent with the average analyst target price of $31.86

1. Increased Probability of Accelerated Approval
   : The strength and reproducibility of biomarker data raise approval likelihood
2. Market Size Growth
   : The global ALS drug market is expected to grow from ~$800M in 2024 to higher levels in the 2030s
3. First-Mover Advantage
   : If approved, it will be the second drug to receive accelerated approval based on NfL
4. Platform Value
   : Potential applications of CNM-Au8 in MS and Parkinson’s Disease enhance platform value

1. Clinical Uncertainty
   : The primary endpoint (ALSFRS-R) did not reach statistical significance, though supported by biomarker surrogate endpoints
2. Increased Competition
   : Biogen/Ionis’s QALSODY is already approved, potentially squeezing market share
3. Execution Risk
   : Ability to transition from clinical development to commercialization
4. Liquidity Discount
   : Low trading liquidity for small-cap stocks

Following discussions at the FDA Biomarker Meeting, the commercialization prospects and valuation logic for Clene’s CNM-Au8 are undergoing significant reconstruction:

• Transition from “High-Risk Clinical Phase” to “Regulatory Near-Term Phase”
• Biomarker data meets the FDA’s requirements for surrogate endpoints, laying the foundation for accelerated approval
• Survival benefit data provides strong evidence of clinical significance
• NDA submission is expected to follow the completion of the Type C meeting in Q1 2026

• Valuation Focus Shifts from Probability Adjustment to Commercial Potential
• The current stock price reflects a significant discount for uncertainty
• Catalyst-driven valuation re-rating opportunity is significant
• Analyst target prices imply ~510% upside; attention is recommended

If positive feedback is received from the Type C meeting, Clene’s valuation is expected to see a significant re-rating from its current low range, with upside primarily dependent on the certainty of accelerated approval and validation of commercial prospects.
