The query "What is the IND procedure in surgery?" can be confusing because the abbreviation "IND" has two very different meanings within medicine. For some, it refers to the minor surgical procedure, Incision and Drainage (I&D). For others, especially those involved in clinical research, it refers to the Investigational New Drug (IND) application required by the U.S. Food and Drug Administration (FDA) to test a new drug or biologic in humans. A third, and equally important, regulatory pathway for surgical innovation involves medical devices, for which the FDA requires an Investigational Device Exemption (IDE).
Incision and Drainage: The Common Surgical Procedure
Incision and Drainage (I&D) is a minor surgical procedure performed to treat abscesses and localized infections by draining accumulated pus. This common procedure involves patient assessment, cleaning and numbing the area, making an incision, draining the pus, and often packing the cavity for continued drainage before applying a dressing.
Investigational New Drug (IND) Application in Surgical Context
Distinct from the I&D procedure, the Investigational New Drug (IND) process is a regulatory pathway to obtain FDA authorization for using an unapproved drug or biologic in human clinical trials. In surgical settings, an IND is necessary when a trial investigates a new drug for surgical use or an approved drug for a new surgical indication.
Types of INDs relevant to surgery:
- Investigator IND: Submitted by a physician conducting a study.
- Emergency Use IND: Allows the use of an experimental drug for a single patient in a life-threatening situation with no alternatives, requiring FDA authorization.
- Treatment IND: Provides access to promising experimental drugs for serious conditions during the final stages of review.
The Investigational Device Exemption (IDE) in Surgical Context
For surgical innovations involving devices, the Investigational Device Exemption (IDE) is the relevant regulatory path. An IDE permits the use of an investigational device in a clinical study to gather safety and effectiveness data. This includes items like new surgical robots or implants.
Key differences between IDE and IND:
- Product Type: IDE is for devices; IND is for drugs and biologics.
- Study Initiation: IND studies can often start 30 days post-submission, while IDE studies typically require FDA approval before beginning, especially for high-risk devices.
The IND, IDE, and Clinical Trial Phases
Both INDs and IDEs require progression through clinical trial phases to ensure safety and effectiveness before FDA approval for broader use.
Comparison of I&D, IND, and IDE
| Feature | Incision and Drainage (I&D) | Investigational New Drug (IND) | Investigational Device Exemption (IDE) |
|---|---|---|---|
| Purpose | To drain pus from an abscess | To study an unapproved drug in humans | To study an unapproved medical device in humans |
| Surgical Context | A minor surgical procedure performed in a clinical setting | Enables a clinical trial testing a drug used in surgery | Enables a clinical trial testing a device used in surgery |
| FDA Role | None, as it's a standard procedure | Formal review and authorization for clinical trials | Formal review and authorization for clinical trials |
| Regulatory Pathway | Standard medical practice | Formal IND application to the FDA | Formal IDE application to the FDA |
| Associated Risks | Minor surgical risks like bleeding, infection, and scarring | Risks associated with a new, untested drug | Risks associated with a new, untested device |
Conclusion: Clarifying IND in Surgical Practice
In summary, the phrase "IND procedure in surgery" is often a point of confusion. The Investigational New Drug (IND) application is a regulatory process for testing investigational drugs or biologics in clinical trials, relevant when a new drug is used in surgery. For device-based surgical innovations, the Investigational Device Exemption (IDE) is the correct regulatory path. Both IND and IDE are crucial for patient safety and the ethical advancement of surgical techniques.
