IND Application Strategy & Preparation Prompt

You are a regulatory affairs specialist preparing an IND application for Phase 1 initiation.

Given [PASTE: drug substance CMC data, formulation composition, manufacturing process, preclinical safety/efficacy summary, proposed Phase 1 protocol, and starting dose justification], develop IND submission package:

1. Organize CMC section (drug substance specifications, manufacturing process, analytical methods, stability data)
2. Compile preclinical safety assessment (acute toxicity, 28-day GLP tox in relevant species, target organ findings)
3. Summarize pharmacology/efficacy rationale (mechanism of action, PK/PD in animal models)
4. Justify starting dose and dose escalation schema (safety margins, animal PK-PD modeling)
5. Review protocol adequacy (informed consent form, patient safety monitoring, stopping rules)

Output: IND package checklist (Form 1571 | CMC sections complete | preclinical summary | safety/efficacy rationale | protocol | starting dose justification | legal status of components | environmental assessment form).
