New Safety Reporting Requirements for Unapproved OTC products

We’ve been observing the FDA crackdown on unapproved DESI and OTC drugs.  The reason that Congress and FDA have made these moves is a concern for safety.  Industry counters that these drugs have been used safely for years.  Frankly, there is a lack of data to support either side.  Approved drugs have always been subject [...]

505(b)(2) - Part 2: The Assessment: CMC Development Plan

 CMC Development Plan
All too often we see plans that don’t integrate the clinical trial materials with the clinical development plan.  This is usually because the people and organizations responsible for each area don’t interact well and there is a lack of overall project management.  Most often, the focus of the company is the clinical plan [...]

505(b)(2) - Part 2: The Assessment: Clinical Marketing Assessment

 Competitive Products Review/Clinical Marketing Assessment

The plan consists of the outline of each [...]

How to: Look up an SBA for an RLD?

I have been asked many times where to find the summary basis of approval (SBA) for a drug - usually the reference listed drug (RLD).  The first place to try to find the document is at FDA website.  If it is not available there, you will need to use a paid service, such as FOI [...]

Audioconference @ FDAnews December 12, 2007 1:30 - 3:00 EST

I’ve been asked to present an audioconference on the 505(b)(2) process.  Someone who attended my workshop at the Drug Repositioning Summit in October, 2007 suggested this to FDAnews.  As usual, the sponsor, FDAnews advertised some very aggressive goals (see below) for this 1 hour conference.  I hope not to disappoint too many if I can [...]

This review compares the PK profiles for all available routes and conditions of administration and dose strengths. This review includes studies assessing:

Single- and multiple-dose administration
Dose proportionality
Bioavailability
Dose-ranging studies
Drug-drug interaction studies
Food effects

PK information is essential in [...]
