Metabolic biomarker feasibility
Frame the package around the first decision your team needs from the data.
Preclinical proof for metabolic research compound
Build NAD+ evidence before managing a lab.
VivoProof acts as a preclinical proof layer for drug builders. Start with a NAD+ research question, then turn it into a scoped evidence plan for systems, samples, endpoints, data closeout, and feasibility review.
NAD+ requests often require extra attention to sample handling, stability, and which biomarker changes would actually answer the research question.
Decision first
Start with the decision the data must support.
A useful request is not just a compound name. It names the decision, the system, the readouts, the reporting standard, and the constraints that could change feasibility.
Tolerability and observation package
Map the system, comparator, sample schedule, and endpoint burden before review.
Sample handling and stability review
Decide whether the first pass needs exposure, tolerability, biomarkers, or tissue work.
Longitudinal endpoint reporting
Specify the closeout standard so the raw tables and summary are useful after the run.
Evidence systems
Choose the smallest credible system for the question.
Many teams start by asking for animal testing. The right first package can also be a cell screen, dish assay, bioanalysis run, or tissue package when that is the smaller credible step.
Organism-level signal
Use when route, tolerability, exposure, metabolic, behavioral, or tissue-level questions cannot be answered in a dish.
Early signal before animals
Use when viability, pathway, direct-cell, or assay feasibility can reduce risk before an in vivo package.
Exposure and sample data
Use for LC-MS/MS, plasma exposure, sample handling, biomarker panels, or material-dependent readouts when available.
Local endpoint package
Use when tissue collection, necropsy, histology, imaging, or local-reaction review is part of the decision.
Inputs before scope
What a real NAD+ request needs.
The Proof Planner can draft a useful starting point, but the formal review depends on material documents, assay availability, sample burden, and the closeout package your team needs.
Material and study inputs
- Compound form, concentration, storage, and handling constraints
- Target biomarkers and sample-processing expectations
- Duration, group structure, and report requirements
Endpoint options
- Body weight, clinical observations, and chemistry panels
- Metabolic biomarkers where assays are available
- Sample inventory, processing notes, and raw tables
What can change feasibility
Stability, sample processing, and assay choice are usually more important than the animal count alone.
Output package
What your team gets back.
VivoProof coordinates the proof package and closeout so the output is useful for internal review, sponsor diligence, or the next experimental decision.
- Sample-handling feasibility brief
- Subject-level endpoint and inventory exports
- Summary report with assay caveats
- Start with the NAD+ question and available material context.
- Select the system, confidence level, sample map, and closeout format in Proof Planner.
- Complete contact and payment-method verification before exact estimate release.
- Feasibility, review path, and next action are confirmed online — no call required.
Public pages avoid protocols, dosing directions, treatment claims, and human-use instructions. Detailed plans are finalized only after research-use review, compound-document review, and facility review.
