| AmlexanoxEligibility HOLD |
Verified product statusHOLD for nomination. US 5% dental paste NDA020511/001 and 2 mg topical patch NDA021727/001: Discontinued. Current eligible systemic product unresolved. | Exact versus other-model evidenceNo exact L737* rescue. CFTR functional signal; contrary NEFL findings with neurite toxicity. GDAP1 staining does not establish full-length protein. | Exposure limitPaste-associated total serum ~0.402 µM is not systemic-tablet PK. Other-gene culture conditions 0.2-25 µM and 100 µM differ by model. Adequate systemic unbound bridge absent. | Functional uncertaintyRNA increase or staining may not yield useful BUBR1. Readthrough can insert a non-native residue. | Current gateResolve product, formulation and jurisdiction before nomination. Require useful identified protein and functional gain at defensible exposure; reject toxicity or cytostasis-only signal. | Decisive experimentIn splice-preserving exact L737* cells, verify allele-specific RNA and both protein termini, then checkpoint and errors per completed division. Measure unbound exposure and viability. |
| MontelukastConditional NMD hypothesis |
Verified product statusUS Rising/Teva 10 mg-base oral tablets ANDA209012/001 and ANDA078605/001: Prescription. This is not organizer eligibility certification. | Exact versus other-model evidenceNo exact BUB1B rescue. Mouse Neuro-2a endogenous AS-NMD reporter-isoform response, not BUB1B target engagement. | Exposure limit5 µM for 5 h in reporter study versus historical mean Cmax ~0.720 µM total plasma; >99% plasma binding. These are not matched free exposures. | Functional uncertaintyExact L737* truncated-protein function is unknown. NMD modulation preserves the stop codon. The related 731X frameshift is not an exact surrogate. | Current gateConditional mechanism branch only. First require useful exact-truncation function. RNA-only response cannot pass; stop if truncation is inactive or harmful. | Decisive experimentExpress exact L737* under controlled abundance; test checkpoint and segregation. Only if useful, test endogenous allele-specific stabilization and functional benefit under credible exposure. |
| Gentamicin + mefloquineExperimental branch |
Verified product statusUS gentamicin injection ANDA062366/001-002 and mefloquine oral tablet ANDA076392/001: Prescription. Combination unapproved for MVA. | Exact versus other-model evidenceNo exact BUB1B rescue. Omachi Figure 6B/D: HEK293 COL4A5-R1563X/G5X NanoLuc reporters, 2/4 mM gentamicin + 20 µM mefloquine, 24 h. G418 panels are separate. | Exposure limitNominal culture concentrations; no justified simultaneous unbound human exposure. Mefloquine total-plasma comparison is not a safety margin. No gentamicin mixture mass conversion. | Functional uncertaintyReporter luminescence does not establish functional BUBR1 or synergy. Full-length readthrough may be non-native. | Current gateExperimental only. Require identified full-length product and gain over the relevant single agent. Stop for unsupported co-exposure, toxicity or absent functional gain. | Decisive experimentCompare both monotherapies, combination, vehicle and corrected controls in exact splice-preserving context. Separate protein identity, checkpoint, segregation and viability endpoints. |
| SirolimusMechanistic comparator |
Verified product statusMechanistic comparator, not current rescue lead. Product-level re-nomination and eligibility not established in this matrix. | Exact versus other-model evidenceNo exact-genotype rescue. Normal-fibroblast RNA feature decreased 41.43% with rapamycin versus proliferative vehicle. Earlier mTOR/SASP evidence is pathway/model dependent. | Exposure limit500 nM continuously for 5 days in GSE65145. No MVA target-tissue PK or functional exposure bridge established. | Functional uncertaintyDeposited RNA feature is not mature-isoform abundance, BUBR1 protein or rescue. Proliferation confounding remains. | Current gateDo not advance an RNA-increase rationale. A downstream branch needs a demonstrated pathway abnormality and separate tissue endpoint with mitotic safety. | Decisive experimentIn genotype-relevant cells, establish the pathway abnormality and test the chosen endpoint with matched proliferation, lineage/viability tracking and errors per division. |
