Note

 

  1.

The test period begins from the completion of the acquisition of the test substance and the arrival of the animals, and lasts until the submission of the final report (draft). (The detailed schedule may be shortened or extended depending on the specifics discussed during the test consultation, and both the test fee and duration may vary depending on the consultation outcome.)

 

  2.

Please arrange a prior consultation before requesting the test, considering the test space and schedule in the animal facility.

If a translated report (English or Japanese) is requested, additional fees and time for preparation will be required.

Example: Submission of the Korean report followed by submission of the English report (translated): Test period + 6 weeks.

 

  4.

Single-Dose Toxicity Study: Additional histopathological examinations will be conducted on organs where gross findings are observed during autopsy, and the cost for these examinations will be charged separately after the study is completed. (Separate cost calculation applies)

 

  5.

DRF (Dose Range Finding Study): The dose determination test (Non-GLP) is necessary to establish the dosage for repeated dose studies.

 

  6.

For rats, histopathological examinations in repeated dose toxicity studies are conducted on the control and high-dose groups. Depending on the results of the high-dose group, additional histopathological examinations may be conducted on the low and medium-dose groups, and the cost for these examinations will be charged separately after the study is completed.

 

  7.

reparation Analysis (active substance or marker substance) is required in GLP studies. The analysis conditions must be provided by the client, and the study cost is based on HPLC standards. If analysis needs to be conducted using other methods, the cost will be determined through separate consultation. (This includes homogeneity, stability, and concentration analysis of the preparation)

 

  8.

Recovery Study: This study is conducted to evaluate the potential recovery from adverse effects observed in repeated dose toxicity studies. It is an important aspect of assessing whether the toxic changes observed in the repeated dose study are reversible or irreversible. The MFDS (Ministry of Food and Drug Safety) recommends conducting recovery studies alongside repeated dose studies.

 

  9.

Beagle Dog Quarantine and Acclimatization: The quarantine and acclimatization period for non- rodent Beagle dogs is approximately two weeks. The study period mentioned is based on the time after the animals are received.

 

  10.

Safety Pharmacology Study: If separate dosing is required, preliminary studies may be added for each test. If additional preliminary studies are conducted, the cost for these will be added separately. (This is based on providing the data needed to determine dosing for the client’s administration)


Trial Fee Statement

 

  11.

Test Standards: MFDS guidelines for toxicity testing of pharmaceuticals and related products.

 

  12.

Payment: The study costs are to be paid in cash.

 

  13.

TK Study: The analysis conditions, standard materials, and internal standard substances (IS) must be provided by the client. (This is based on the client’s provision of the bioanalytical method)

 

  14.

TK and ADA Analysis: These analyses will be conducted as multi-site studies at GLP-certified analysis institutions.
