FDA IND · End-to-end

From preclinical candidate to FDA-active IND.

16 specialist Claude agents draft every IND artifact. Nine human-signed gates anchor each milestone to the artifact hash. A tamper-evident audit chain records every action. Built for 21 CFR Part 11 and ICH E6(R3).

Platform

Every IND artifact, drafted, hashed, and signed.

The platform owns the full IND lifecycle — from drug-candidate intake through FDA submission and the 30-day review clock. Specialist agents read sponsor-supplied source data; named regulatory leads e-sign each milestone with WebAuthn; nothing crosses a gate without a manifest hash.

Intake & classification

IND Type Classifier

Agent 1 classifies Commercial / Investigator / Emergency Use / Treatment / Expanded Access per 21 CFR 312, and routes CDER vs CBER. Devices bounce to QB510K.

Pre-IND meeting

Type B briefing

Agent 2 drafts the meeting request, questions, and briefing book per FDA's 'Formal Meetings with FDA' guidance. Outcomes integrate before Gate 2.

CMC · Module 3

Drug substance + product

Agent 3 drafts §3.2.S and §3.2.P per ICH Q1/Q2/Q3/Q6 + 21 CFR 211 cGMP. Stability tables, manufacturing process, specifications.

Nonclinical · Module 4

GLP-aware drafting

Agent 4 maps studies to ICH S1–S11, drafts §2.6 + §4.2, flags non-GLP studies before they hit Gate 4.

Clinical · Module 5

Protocol + SAP + IB

Agents 5–7 draft dose-escalation protocols, ICH E9(R1) estimands, and ICH E6(R3) §8.3 Investigator's Brochures.

Assembly · ESG

eCTD v3.2.2 + ESG

Agents 8–10 fill Forms 1571/1572/3674, assemble the five-module eCTD, validate structurally, and submit via Playwright RPA.

How it works

Six phases. Nine signed gates. One audit chain.

The platform never advances on its own. Every milestone is a named human's signed decision, bound to the artifact hash they reviewed.

01

Intake & classification

Drug-candidate intake. The IND Type Classifier returns ind_type, fda_center, and review division. CBER routing for biologics fires early — a misroute caught at Gate 1 saves the 60 days a wrong-center submission would cost.

Gate 1 · RA Lead
02

Pre-IND meeting

Agent 2 drafts the Type B meeting request, list of questions, and briefing document. FDA responses thread into downstream artifacts — a stopping rule FDA asks for in Q3 shows up in the protocol automatically.

Gate 2 · RA Lead
03

CMC + Nonclinical drafting

Agents 3 and 4 draft Module 3 and Module 4 in parallel. QC Lead reviews CMC, Tox Lead reviews nonclinical. Blocking GLP issues flagged before sign-off.

Gate 3 + Gate 4
04

Clinical protocol + IB

Agents 5 and 6 draft the Phase 1/2/3 protocol with SAP and the Investigator's Brochure. Medical Monitor + RA Lead countersign both.

Gate 5 + Gate 6
05

eCTD assembly + Forms

Agent 9 builds the eCTD v3.2.2 package; structural validation runs. Forms 1571/1572/3674 generated. Sponsor signatory signs Form 1571 with WebAuthn at Gate 8.

Gate 7 + Gate 8
06

ESG submission + 30-day clock

Agent 10 submits via FDA's Electronic Submissions Gateway. The 30-day review clock starts at FDA receipt. Agents 11–14 handle the lifecycle: clock tracking, safety reports, annual reports, amendments.

Regulatory coverage

Built for the FDA. Aligned with ICH.

The data model is multi-jurisdiction by design. The same artifacts that satisfy an FDA IND feed an EMA CTA, an MHRA CTA, or a PMDA Phase 1 notification — without re-keying.

United States — FDA / CDER / CBER

  • 21 CFR Part 312 — Investigational New Drug
  • 21 CFR Part 11 — electronic records & signatures
  • 21 CFR Part 56 — IRBs
  • 21 CFR Part 50 — informed consent
  • 21 CFR Part 58 — Good Laboratory Practice
  • 21 CFR Part 211 — current Good Manufacturing Practice
  • FDA ESG — Electronic Submissions Gateway
  • FDA AA Section 801 — ClinicalTrials.gov registration

ICH-aligned for multi-region submissions

  • ICH M4 — CTD organization
  • ICH E6(R3) — Good Clinical Practice
  • ICH E9(R1) — Estimands & sensitivity analyses
  • ICH Q1A(R2) through Q6 — CMC
  • ICH S1–S11 — Nonclinical
  • ICH M3(R2) — Nonclinical safety for clinical trials
  • EMA CTA (Voluntary Harmonisation) compatible
  • PMDA / MHRA / Health Canada artifact reuse

Software validation — GAMP-5 Category 5

Security & compliance posture

Designed for the questions a regulator and a CISO ask.

Personal data, sponsor data, and regulatory artifacts share a tenant boundary and an audit boundary. Nothing crosses without a signed record.

Identity

Two-factor on every signature.

Login is bearer-JWT with mandatory FIDO2 / WebAuthn second factor when enrolled. Every Gate signature additionally requires the e-signature PIN AND a fresh WebAuthn assertion bound to the artifact hash — replay-resistant per 21 CFR Part 11 §11.200(a). Roaming security keys and platform biometrics both supported.

Data protection

Encrypted at rest. Encrypted in transit. Tenant-isolated.

AES-256 at rest, TLS 1.2+ in transit, per-tenant Row-Level Security at the database tier as a defense-in-depth layer. Service-role credentials never leave the backend. No sponsor data is used to train models.

Personal data

HIPAA / GDPR / LFPDPPP-aware data handling.

Personal and patient identifiers are scoped to the records that require them, with retention boundaries and deletion paths. Data Subject Access Requests are first-class operations, not a manual export. Sub-processors and data-processing agreements are documented per region.

Audit & forensics

Tamper-evident, not just append-only.

Every action — login, signature, agent run, document mutation — appends to a SHA-256 hash-chained ledger anchored to a genesis event. A standalone verifier walks the chain on demand. If any row is altered, the verifier reports exactly which link broke.

Source-of-truth grounding

No hallucinated regulatory citations.

Agent citations resolve against live FDA guidance pages and the eCFR. The query and the result hash are logged. An agent that cannot ground a claim refuses to emit it — the open-items list flags what needs human research.

Operations

SOC 2–aligned controls. Live observability.

Sentry error reporting, OpenTelemetry traces to a managed backend, structured logs retained per policy. RPO / RTO targets defined and tested. Quarterly DR tabletop. Access reviews on a fixed cadence.

Why teams switch

An IND program, redesigned around the bottleneck.

The slow part of an IND isn't the FDA review — it's the months spent producing the submission. RegBridge removes the drafting bottleneck without removing the regulatory rigor.

Time to submission

Weeks, not quarters.

The classic IND cadence is 12–18 months of drafting, redlines, vendor handoffs, and section-by-section assembly. RegBridge parallelises every section and ships an eCTD-ready package in weeks. Pathway, CMC, nonclinical, protocol, and IB drafts move concurrently.

Risk on the review clock

Catch the deficiency before the FDA does.

Deterministic eCTD validation pre-checks run the FDA's own acceptance criteria against your submission before you upload. The 30-day review clock is tracked in real time with T-21 / 14 / 7 / 3 / 0 alerts. Misrouted CDER/CBER products are caught at Gate 1.

Audit readiness

Every action is on the record.

Hash-chained audit ledger, e-signatures bound to artifact hashes, signature manifests for every milestone. When an FDA inspector or an internal auditor asks who approved what, when, and against which version — the answer is one query away.

See it for yourself

Stand up an IND program and walk it through its first submission.

Pick a sponsor name, name an RA Lead, and the platform seeds a tenant for you. Every action from that point is a real 21 CFR Part 11 event in your own audit chain — signed, hashed, retained.
