Essential Elements of a Successful IND Package

Posted on digi By digi

An Investigational New Drug (IND) application is a regulatory prerequisite for initiating clinical trials in the United States. It allows sponsors to legally ship an investigational drug across state lines before a marketing application is approved. The U.S. Food and Drug Administration (FDA) reviews the IND to ensure that trial participants are not exposed to unreasonable risks. Preparing a successful IND submission package is a complex but vital step in drug development.

Common Reasons for IND Clinical Hold and How to Avoid Them

Posted on digi By digi

A clinical hold is an order issued by the U.S. FDA that prevents the initiation or continuation of a clinical trial under an Investigational New Drug (IND) application. While the purpose is to protect trial participants from potential harm, a hold can result in major delays, increased costs, and a loss of investor confidence.

Pre-IND Meeting: What to Prepare and Expect

Posted on digi By digi

A Pre-Investigational New Drug (Pre-IND) meeting is one of the most valuable opportunities for sponsors to engage with the FDA early in the drug development process. Classified as a Type B meeting, it enables sponsors to align their nonclinical, clinical, and Chemistry, Manufacturing, and Controls (CMC) plans with FDA expectations before submitting an IND application.

Nonclinical Data Requirements for IND Filing

Posted on digi By digi

Nonclinical (also known as preclinical) data are a critical component of any Investigational New Drug (IND) application. These studies establish the safety profile of a new drug before it is administered to humans. They serve to identify potential toxicities, support dose selection, and define monitoring strategies for the proposed clinical trial.

CMC Module in IND Submissions: Best Practices

Posted on digi By digi

The Chemistry, Manufacturing, and Controls (CMC) module is a cornerstone of the Investigational New Drug (IND) application. It demonstrates that the investigational product can be manufactured reliably, stored safely, and administered consistently. Inadequate or incomplete CMC data is one of the most common causes of IND clinical holds.

IND Amendments: Process, Timing, and Compliance

Posted on digi By digi

Once an Investigational New Drug (IND) application is active, sponsors are responsible for maintaining its accuracy and ensuring that all changes are communicated promptly to the FDA. This is achieved through IND amendments — formal submissions that update the agency on protocol modifications, safety findings, manufacturing changes, or administrative updates.

Initial vs Expanded Access INDs: Key Differences

Posted on digi By digi

An Investigational New Drug (IND) application allows sponsors to legally administer an unapproved drug to humans. While most INDs are submitted to initiate clinical trials (initial INDs), the U.S. Food and Drug Administration (FDA) also provides a mechanism called Expanded Access IND — commonly referred to as “compassionate use” — for patients with serious or life-threatening conditions who lack other treatment options.

How to Prepare for a Type B FDA Meeting

Posted on digi By digi

In the U.S. drug development process, structured communication with the Food and Drug Administration (FDA) is essential for aligning clinical, regulatory, and manufacturing strategies. Type B meetings are formal, scheduled interactions between sponsors and the FDA designed to address key development milestones, including Pre-IND meetings, End-of-Phase 2 meetings, and Pre-NDA/BLA meetings.

eCTD Format for IND Submissions in the U.S.

Posted on digi By digi

The electronic Common Technical Document (eCTD) is the mandatory format for submitting Investigational New Drug (IND) applications to the U.S. Food and Drug Administration (FDA). As of May 2018, the FDA requires that all commercial INDs, including amendments and safety updates, be submitted electronically using eCTD specifications.

Case Study: Successful IND for First-in-Human Study

Posted on digi By digi

This case study highlights a mid-sized biotechnology company preparing to enter clinical trials with a novel small-molecule kinase inhibitor. The molecule was developed to treat relapsed/refractory acute myeloid leukemia (AML) and showed strong preclinical efficacy across multiple cell lines and animal models.
