Delegates’ reasons for final decisions

PART A – FInal Decisions on Matters REFERRED TO AN ADVISORY COMMITTEE

1. Matters Initially Referred to ACCS#1 – February 2011

1.1Cefquinome

DELEGATE’S REFERRAL TO EXPERT ADVISORY COMMITTEE

The delegate considered the scheduling of cefquinome and decided to seek advice from the ACCS on the following:

Cefquinome – proposal to include cefquinome in Schedule 4.

EXPERT ADVISORY COMMITTEE RECOMMENDATION

The Committee recommended that a new Schedule 4 entry be created for cefquinome. The Committee also recommended an implementation date of no more than 6 months after the delegate’s final decision.

BACKGROUND

Currently the SUSMP prefers the use of sulfate rather than sulphate.

Cefquinome sulfate belongs to the cephalosporin group of antibiotics which act by inhibition of cell wall synthesis, resulting in bacterial cell death. The structure is:

XXXXX has submitted data to the Australian Pesticides and Veterinary Medicines Authority (APVMA) seeking the approval of a new active ingredient, cefquinome sulfate, and the registration of XXXXX.

XXXXXRisk Assessment Technical Report on XXXXX APVMA submission included a scheduling recommendation for cefquinome sulfate. A delegate agreed that this was a matter for a scheduling consideration and that advice from the ACCS was needed.

SCHEDULING STATUS

Cefquinome is not specifically scheduled. It would, however, be captured by the Schedule 4 group entry for antibiotic substances.

INITIAL SUBMISSIONS

Applicant’s Submission

The XXXXX Risk Assessment Technical Reportconcluded that, based on the toxicity profile of cefquinome sulfate and the need for veterinary diagnosis of the indicated condition XXXXX, cefquinome sulfate should be included in Schedule 4.

Other XXXXX conclusions included:

  • There were no objections on human health grounds to the approval of the active ingredient cefquinome sulfate or to the registration of the product.
  • As the product was an antibiotic and not intended to be used in food-producing animals, establishment of an ADI and ARfD for cefquinome sulfate was not required. If cefquinome sulfate were to be used in the future to treat food producing animals, a microbial ADI and/or toxicological ADI would have to be established.
  • XXXXX.
  • No re-entry, re-handling, warning or precautionary statements were required.

Members noted that the applicant submitted studies to the APVMA on toxicokinetics and metabolism, acute toxicity, subchronic toxicity, genotoxicity, developmental and reproductive toxicity. Although most studies did not strictly conform to current test guidelines or standards of reporting, they were considered acceptable by the evaluator for the assessment of the toxicology profile of cefquinome sulfate in this case.

Toxicology

Members noted the following toxicology summary for cefquinome sulfate:

XXXXX

  • Cefquinome sulfate had low acute oral toxicity XXXXX, low acute intravenous XXXXX and subcutaneous toxicity XXXXX.
  • Cefquinome sulfate was not a skin sensitiser in XXXXX. No acute inhalation toxicity, skin or eye irritation studies were provided. However, based on the use pattern of the product, exposure by these routes was likely to be minimal.
  • Repeat-dose oral toxicity studies were performed in XXXXX. The main toxicological effect noted in XXXXX was increased kidney weight and changes in clinical chemistry and urinalysis parameters suggestive of an alteration in renal function, as well as vacuolisation of the epithelial cells of the convoluted proximal tubules of the kidney. Enlargement of the caecum was also seen but without corroborative histological findings. This was likely due to changes in the intestinal microflora, which is a side effect common to cephalosporin antibiotics. In XXXXX, interference with hepatic synthesis of certain molecules such as cholesterol and triglycerides was observed, and liver weights were increased without corroborative histological findings.
  • In a XXXXX reproduction study, there were no effects on reproductive parameters, and cefquinome sulfate was not a developmental toxicant XXXXX developmental toxicity study. Studies on carcinogenicity were not provided, however, cefquinome sulfate was not mutagenic or genotoxic in in vitro studies, or genotoxic in an in vivo study.

Members additionally noted the results of a study designed to determine the minimum inhibitory concentration of cefquinome sulfate against a range of bacteria genera and strains that were representative of the human colonic microflora, bacterial suspensions were inoculated into agar plates at two different densities. No strain was sensitive to cefquinome at concentrations below XXXXX. The most sensitive species was XXXXX.

Members noted that no toxicity studies were submitted for the product. The acute oral and dermal toxicity was estimated from the available toxicity data on the active constituent and other constituents as summarised below:

Toxicity end point / Toxicity of Product
Oral / Low
Dermal / Low
Inhalational / No data
Skin irritation / No data
Eye irritation / No data
Skin sensitisation / Unlikely

Use Pattern / Exposure

Members noted the following summary of use pattern and exposure information from the XXXXX report:

  • XXXXX.
  • The product would be administered by qualified veterinarians and trained farmers, so any potential for exposure will be restricted to these trained individuals who would be aware of the possible toxicity associated with the product.
  • XXXXX.

Hazard Classification

Cefquinome is not listed on Safe Work Australia’s Hazardous Substances Information System (HSIS) Database. The XXXXX has determined that both cefquinome sulfate and the product are not classified as a hazardous substance according to NOHSC Approved Criteria for Classifying Hazardous Substances.

Applicant’s Response to the Evaluation Report

XXXXXhad considered the XXXXXReport, including the scheduling recommendation, and advised that there were no comments.

February 2011 Pre-meeting Submissions

No pre-meeting submissions were received.

EXPERT ADVISORY COMMITTEE DISCUSSION

Members generally agreed that relevant matters under Section 52E (1) included (a) risks and benefits; and (b) the purpose and extent of use.

Members noted that as cefquinome sulfate was an antibiotic substance it was already captured by Schedule 4. Members also agreed that there was no information to suggest that anything other than supply by prescription should apply to the availability of cefquinome sulfate. For clarity, Members agreed that a separate specific listing in Schedule 4 would be appropriate.

Members then discussed the wording of a specific Schedule 4 entry. Members noted the precedent for schedulinga parent substance rather than a specific salt unless the salt has unique toxicity. Members agreed that there were no data to indicate unique toxicity and a parent entry for cefquinome was considered to be sufficient. A Member also suggested limiting the specific entry to animal use only, on the presumption that the group entry for antibiotic substances would still capture any potential human use. Other Members clarified that the group entry would not apply if there was a specific entry i.e. limiting the cefquinome entry to animal use would mean that cefquinome for any other use, including human use, would then be unscheduled. A Member particularly raised the concern that inappropriate access through importation for personal human use could occur if such use were not classed as Schedule 4. The Committee agreed that the specific entry needed to remain broad to capture all potential uses of cefquinome.

A Member noted that there had been considerable controversy overseas, particularly in the US, over the use of cefquinome in animals. Cefquinome is a 4th generation cephalosporin and the Member had concerns about the use of a 4th generationantibiotic in animals as this could potentially lead to increases in antibiotic resistance. Members noted advice that the APVMA would investigate these claims, noting that the cost of this antibiotic was likely to mitigate any propensity for misuse or abuse. Members noted that while this was an issue that APVMA was aware of, it was yet another reason for cefquinome to be Schedule 4.

DELEGATE’S INTERIM DISCUSSION

The delegate concluded that the recommendations of the ACCS were clear and appropriately supported. The delegate agreed with these recommendations.

The delegate agreed that the relevant matters under section 52E (1) of the Therapeutic Goods Act 1989 included (a) risks and benefits and (b) the purpose and extent of use.

DELEGATE’S INTERIM DECISION

The delegate decided to include cefquinome in Schedule 4. The delegate decided that an implementation date of 1 January 2012 was appropriate (i.e. six months after publication of the final decision).

SUBMISSIONS ON INTERIM DECISION

No submissions were received on the interim decision.

DELEGATE’S FINAL DECISION

The delegate confirmed that cefquinome be included in Schedule 4. The delegate also confirmed an implementation date of 1 January 2012.

Schedule 4 – New entry

CEFQUINOME.

1.2Derquantel

DELEGATE’S REFERRAL TO EXPERT ADVISORY COMMITTEE

The delegate considered the scheduling of derquantel and decided to seek advice from the ACCS on the following:

Derquantel – proposal to include derquantel in Schedule 6 with a cut-off to Schedule5 for preparations containing 1 per cent or less of derquantel.

EXPERT ADVISORY COMMITTEE RECOMMENDATION

The Committee recommended that a new Schedule 6 entry be created for derquantel, with a cut-off to Schedule 5 for preparations containing 1 per cent or less of derquantel. The Committee also recommended an implementation date of no more than six months after the delegate’s final decision.

BACKGROUND

Derquantel is a member of the spiroindole class of anthelmintics. It acts as a selective nicotinic antagonist in somatic muscle by competing for the ganglionic nicotinic cholinergic receptors, thus inducing flaccid paralysis in parasitic nematodes. Its structure is:

XXXXX.

XXXXX has submitted data to the Australian Pesticides and Veterinary Medicines Authority (APVMA) seeking approval for the active ingredient derquantel and the registration of XXXXX.

The XXXXX Risk Assessment Technical Report on XXXXX APVMA submission included a scheduling recommendation for derquantel. The delegate agreed that this was a matter for a scheduling consideration and that advice from the ACCS was needed.

SCHEDULING STATUS

Derquantel is not currently scheduled.

INITIAL SUBMISSIONS

Applicant’s Submission

The XXXXXReportfound that derquantel presents a hazard for repeated use, and although it is considered unlikely to produce irreversible toxicity it is a competitive nicotinic antagonist that has produced clinical signs of neurotoxicity in XXXXX. Thus, the evaluator concluded that derquantel met the requirements of a Schedule 6 chemical. The evaluator recommended that derquantel be included in Schedule 6 with a 1 per cent cut-off to Schedule 5.

Other XXXXX conclusions included:

  • There were no objections on human health grounds to the approval of active ingredient derquantel XXXXX.
  • The ADI for derquantel was established at 0.0005 mg/kg bw/d based on a LOEL of 0.1 mg/kg bw/d in a XXXXX and using a 200-fold safety factor.
  • The ARfD for derquantel was established at 0.01 mg/kg bw based on a NOEL of 1 mg/kg bw in an XXXXX and using a 100-fold safety factor.
  • Recommended labelling included the safety directions “May irritate the skin” and “Avoid contact with the skin”. Members noted, however, that Appendices E and F do not apply to products regulated by the APVMA. APVMA sets these labelling requirements as part of its product approval process.
  • No re-entry, re-handling, warning or precautionary statements are required.

Members also noted the following further information regarding derquantel’s mode of action in mammals:
