Technical Overview: The FDA ANDA Process for Generic Drug Approval

Technical Overview: ANDA Approval Process (Simplified)

The Abbreviated New Drug Application (ANDA) under Section 505(j) of the FD&C Act allows approval of a generic drug by demonstrating pharmaceutical equivalence and bioequivalence (BE) to a Reference Listed Drug (RLD).


1. RLD Identification & Pre-Submission Assessment

  • Select the RLD from the Orange Book.
  • Evaluate formulation sameness (Q1/Q2) where required, especially for complex products.
  • Review exclusivities, perform patent certifications (Paragraph I–IV), and check suitability requirements (21 CFR 314.93).

2. Formulation & CMC Development

  • Develop a formulation that is pharmaceutically equivalent to the RLD and aligned with its quality attributes.
  • Perform risk assessments per ICH Q8–Q11.
  • Establish a control strategy including API characterization, polymorph form, particle size, and excipient compatibility.

3. Analytical Method Development & Validation

  • Develop and validate stability-indicating analytical methods as per ICH Q2(R2).
  • Conduct method robustness and transfer readiness studies.
  • Perform impurity profiling (ICH Q3A/Q3B), evaluate residual solvents (ICH Q3C), and assess elemental impurities (ICH Q3D).

4. Bioequivalence (BE)

  • Conduct in-vivo BE studies per 21 CFR 320, or request a BCS-based biowaiver when applicable.
  • Use partial or full replicate designs for highly variable drugs.
  • Demonstrate BE using pharmacokinetic parameters with 90% CI falling within 80–125%.

5. Stability Studies

  • Perform real-time and accelerated studies per ICH Q1A(R2).
  • Generate stability data for exhibit/commitment batches, covering all critical quality attributes.

6. ANDA Dossier Preparation (CTD Format)

  • Module 1: Administrative information, patent certifications (Paragraph I–IV), and labeling (PLR format).
  • Module 2: Quality overall summaries (QOS).
  • Module 3: CMC sections for drug substance (3.2.S) and drug product (3.2.P), including characterization, specifications, validation, container closure details, and batch results.
  • Module 4: Nonclinical data (only if needed).
  • Module 5: BE/biowaiver data.

7. ANDA Submission Under GDUFA

  • Submit application via eCTD.
  • Pay GDUFA application and facility fees.
  • FDA begins filing review, CMC evaluation, labeling review, BE assessment, and facility inspection planning.

8. FDA Interactions

  • Respond to Information Requests (IRs), Discipline Review Letters (DRLs), or Complete Response Letters (CRLs).
  • Address inspection observations (Form 483) and implement CAPA as needed.
  • Ensure proper DMF linkage and maintain a valid Letter of Authorization.

9. Approval or Tentative Approval

  • Final Approval: Issued when all scientific requirements are met and no patent/exclusivity barriers exist.
  • Tentative Approval: Issued when scientific review is complete but approval is blocked by existing exclusivity.
