Ken-at-DRC-Chicago-bIn 2003, Camargo was founded in Cincinnati by Ken Phelps (president and CEO) and Dr. Ruth Stevens (chief scientific officer and executive vice president). It’s no coincidence that 2003 was also the year the FDA introduced guidelines governing the 505(b)(2) approval pathway. From the beginning, Camargo has focused solely on being the industry’s 505(b)(2) development partner of choice. Just five years after opening, Camargo was recognized as one of Cincinnati’s 55 fastest-growing private companies. In 2011, Camargo opened a second location in Durham, N.C., in the Research Triangle Park. Today, Camargo partners with companies in more than 25 countries worldwide and has led the largest percentage of 505(b)(2) submissions of any team submitting to the FDA — Camargo is the industry authority in 505(b)(2).

Marketed Product Types

The 505(b)(2) approval pathway can be used for any approved or unapproved compound for which there is sufficient public data and is particularly useful for those compounds that represent a limited change from an approved drug.

Ideal candidates include:

  • Drugs with new indications for an approved drug
  • Drugs with changes in dosage form, strength, formulation, dosing regimen or route of administration
  • New combination products (i.e., drug/device, biologic/device, drug/biologic or drug/device/biologic)
  • Drugs with new active ingredients (i.e., ones not previously approved in the US, but where significant information exists about the active ingredient’s safety and efficacy)
  • Prodrugs of an existing drug (Read More)
  • Branded generics (Read More)

*Camargo’s customized approach to navigating the 505(b)(2) development pathway presents the opportunity to secure approval for DESI drugs. The FDA’s DESI program was enacted to evaluate the efficacy of all drug products approved and marketed on safety grounds alone between 1938 and 1962. Although these DESI-approved drugs may continue to be marketed until the administrative proceedings evaluating their effectiveness have concluded, continued marketing is permitted only if an NDA is approved for such drugs. Currently, the FDA is pursuing an Unapproved Drugs Initiative against as many as 3,000 drugs still on the market without approval. For many of these drugs still in limbo, a direct path to an NDA and possible marketing exclusivity may be obtainable.
