NATIONAL COORDINATOR FOR AQUACULTURE NEW ANIMAL DRUG APPLICATIONS (NADAs)

THIRD MID-YEAR REPORT OF ACTIVITIES

 May 15, 1998 to November 9, 1998


 MID-YEAR SUMMARY OF ACTIVITY HIGHLIGHTS FOR THE NATIONAL

COORDINATOR FOR AQUACULTURE NEW ANIMAL DRUG APPLICATIONS

(May 15, 1998 to November 9, 1998)

 

PROJECT OBJECTIVES

The overall goal of this project is for the National Coordinator for Aquaculture New Animal Drug Applications (National NADA Coordinator) to coordinate activities for investigational new animal drug exemptions (INADs) and new animal drug applications (NADAs) to expedite approval for the use of various drugs in aquaculture. Specific objectives related to that goal are to:


PROGRESS AND PRINCIPAL ACCOMPLISHMENTS

The National NADA Coordinator provided many information transfers this one-half year and worked to obtain INADs, NADAs and approvals for a number of drugs that are considered to be of high priority for approval by the public and private aquaculture community.

THERAPEUTANTS

Amoxicillin (oral antibacterial)--Status: Two sponsors have submitted INAD/NADA letters of intent; early development stage

Chloramine-T (external antibacterial)--Status: Sponsor has committed to INAD/NADA; major effort for NADA approval under the IAFWA Project and compassionate INADs; at least two years from approval

 

Copper Sulfate (external microbicide)--Status: Sponsor submitted INAD/NADA letter of intent and product chemistry technical section; major effort for approval under the IAFWA Project and compassionate INADs; one year or less from NADA approval

 

Cutrine-Plus™ (external microbicide)--Status: Some interest by potential sponsor; early development stage

Diquat Dibromide (external microbicide)--Status: No commitment by potential sponsor; early development stage

Earth Tec Algicide/Bactericide™ (external microbicide)--Status: Sponsor recently submitted INAD/NADA letter of intent; early development stage

Enrofloxacin (oral antibacterial)--Status: INADs inactive in the United States because of fluoroquinolone issues; no sponsor interest

Erythromycin (oral antibacterial)-Status: Sponsorship needs to be resolved; all technical sections except sponsor product chemistry submitted; risk assessment needed on potential for disease resistance; near NADA approval for bacterial kidney disease in salmonids if gain sponsor

Florfenicol (oral antibacterial)--Status: Sponsor recently allowed the development of florfenicol for approval in United States; approved in Canada in August 1997; IAFWA Project drug; at least two years from any NADA approval

Formalin (external microbicide)--Status: IAFWA Project drug; Supplemental NADA approved on June 18, 1998 for control of certain fungi on the eggs of all finfish and certain external protozoa and monogenetic trematodes on all finfish; at least one year away from expansion of the NADA for its use to prevent mortalities associated with external fungal infections on all cultured freshwater fish

Fumagillin (microsporidiosis control)--Status: Sponsor recently submitted INAD/NADA letter of intent; several efforts to collect efficacy data in public and private sector; early development stage

Hydrogen peroxide (external microbicide)--Status: Currently considered as a low regulatory priority drug for use as a fungicide on fish and fish eggs but CVM has encouraged the development of a NADA; one U.S. sponsor is interested in gaining an NADA approval; IAFWA Project drug; efficacy (eggs and fish) and target animal safety technical sections submitted; human food safety data requirements are met; at least one year from NADA approval in the U.S. if data from Canada are acceptable.

Neomycin sulfate (vibriosis control)--Status: Currently no activity on this drug

Oxytetracycline (OTC, oral antibacterial)--Status: Currently approved for control of certain bacterial diseases in catfish, salmonids, and lobsters and as a marking agent in Pacific salmon; IAFWA Project drug; near-term approval as marking aid on all cultured freshwater fish and as a control for bacterial diseases on shrimp; at least one year from NADA approval for certain extensions and expansions for cultured freshwater fish.

Potassium Permanganate (external microbicide)--Status: Sponsor recently submitted an INAD/NADA letter of intent; major effort for NADA approval under IAFWA Project; two to three years from approval

Pet Fish Therapeutants (various drugs and pesticides)--Status: Major effort to resolve non-food fish issue for these drugs by private consultant

Praziquantel (trematode and cestode control)--Status: Some interest on the part of potential sponsor in a U.S. NADA approval but needs positive marketing information; has approval in several countries

Pyceze™ (external microbicide)--Status: Sponsor recently submitted an INAD/NADA letter of intent and all major technical sections; at least one year from approval

Quinine (internal microbicide)--Status: Some interest on the part of potential sponsor in a U.S. NADA approval if market is large enough

Sarafloxacin (oral antibacterial)--Status: Previously, most of the NADA technical sections were submitted by Abbott Laboratories and accepted by CVM for control of enteric septicemia in catfish. Recently, the Centers for Disease Control and Prevention have presented concerns about the use of all fluoroquinolones in animal health because of the potential for developing pathogen resistance to drugs used in humans. It is doubtful that a new NADA on sarafloxacin or any fluoroquinolone will be allowed for aquaculture uses by CVM. Sarafloxacin was replaced by florfenicol as the oral antibacterial and model drug for crop grouping research in January 1998 by an unanimous vote of the IAFWA Project stakeholders.

Sea Lice Control (various drugs and pesticides)--Status: Various drugs and pesticides ( azamethiphos or Salmosan™, cypermethrin or Excis™) are being pursued by the United States and Canada and are at various stages of registration and approval

Trichlorfon (external parasite control)--Status: Some interest on the part of potential sponsor in a U.S. NADA approval; has approvals in several countries; Special Local Need registrations granted in 1998

 

ANESTHETICS

Aqui-S™/Aqui-S Plus™--Status: Sponsor proceeding with worldwide drug approval; drug being assessed by the IAFWA Project; at least two years from approval in the United States

Benzocaine--Status: Major effort by IAFWA Project for NADA approval terminated because of decision by IAFWA Project stakeholders to select Aqui-S™ as the candidate anesthetic in the U.S. public aquaculture sector; no known drug approval activities underway

MS-222--Status: Two approved NADAs for MS-22 as an anesthetic with a 21-day withdrawal time

Oil of Cloves--Status: Oil of cloves (eugenol) is considered Generally Recognized as Safe (GRAS) when used as a direct food additive (21CFR184.1257); however, to use eugenol as an anesthetic on fish, it must be approved by CVM for that purpose. A sponsor is required to proceed toward approval and no sponsor has come forward; no known drug approval activities underway

 

SPAWNING AND GENDER MANIPULATION AIDS

Common Carp Pituitary (CCP)-- Status: Sponsor and interested parties proceeding toward NADA approval; at least one year from NADA approval

Gonadotropin Releasing Hormone (GnRH)--Status: Sponsor recently submitted INAD letter of intent; early development stage

Human Chorionic Gonadotropin (hCG)--Status: Near-term NADA approval in the United States

Ovaprim™--Status: Sponsor recently submitted INAD letter of intent; early development stage

17 -methyltestosterone (MT)--Status: Sponsor is developing NADA package; INAD sponsors actively pursuing a NADA approval; NADA approval anticipated when environmental and product chemistry requirements are met
