21 CFR Part 312 · Investigational New Drug Applications

IND Preparation & Submission

From pre-IND feedback to an IND in effect. ADB authors, assembles, and submits Investigational New Drug applications under 21 CFR Part 312 — extending the same disciplined regulatory practice we built in medical devices to drug development programs.

A Growing Practice

A Regulatory Practice That Now Spans Drugs and Devices

For years ADB's core work has been guiding medical devices through FDA. That discipline — verified sources, defensible timelines, no assumption left unstated — now extends to the drug side of the agency. Our IND practice covers small molecules and complex programs alike, including Schedule I controlled substances and psychedelic-derived drug products, where DEA coordination and scheduling strategy run alongside the FDA pathway.

Where Every Engagement Starts

Every Engagement Starts With a Readiness Assessment

Before ADB commits to a submission timeline, we run a fixed-scope readiness assessment of your source materials — nonclinical, clinical, and CMC. It ends in a written verdict: GO, GO WITH GAPS, or HOLD. You learn exactly what stands between your program and a fileable IND before the larger engagement begins, and every downstream assumption is recorded in an inputs register — nothing is priced or promised on faith.

Engagement Structure

Two Ways to Structure the Work

Source Content Ready

Assembly & Submission

Your source content is ready. ADB assembles, authors the regulatory narrative, compiles the eCTD, and submits.

Typical path: 14–16 weeks to submission

Timelines assume readiness-assessment findings are resolved and reflect FDA's standard 30-day IND review clock. Well-prepared INDs have cleared in as little as 26 days.
