Key exclusion criteria
(1) Intake of any investigational drug in another study within 30 days (or 5 half-lives, whichever is greater) prior to intake of IMP in this study or have received the last dose of a study drug more than 30 days ago (or 5 half-lives, whichever is greater) but who are on extended follow-up, or planned intake of an investigational drug (other than for this study) during the course of this study.

If a potential subject is considered by Investigator to have false positive result (ex. HIV antibodies) at screening, then a repeat test should be done as soon as possible and if retest is negative, the subject can be considered eligible for the study.

b. Total bilirubin > 1.5 times of upper normal limit
Note: Safety laboratory tests can be repeated if the subject is clinically asymptomatic in relation to abnormal result and Investigator strongly believes this is not clinically significant. One re-test is allowed. If the result still meets the exclusion criteria, subject will be excluded.
(8) Subject who has immune deficiency or medication with immunosuppressive agents.
(9) Treatment with any medication prescribed or over-the-counter (OTC) products including herbal remedies within 14 days prior to Day 1 or longer if the medication has a long half-life, unless agreed as not clinically significant by the Investigator and Sponsor. Exceptions: hormonal contraceptives, acetaminophen less than or equal to 3 g/day, vitamins at daily recommended doses.
(10) Donated whole blood products (e.g., plasma, platelets) within 60 days, or transfused within 20 days before Screening.
(11) History of alcohol or drug abuse or drug addiction (including cannabis products) within the last 12 months before Screening.
(12) Subject is unwilling to comply with the alcohol restrictions. The subject should refrain from drinking any alcohol within 72 hours prior to Day -1, and should not consume more than 3-4 units of alcohol per day to a maximum of 14 units of alcohol per week (1 unit of 10 mL of pure alcohol, 12 ounces [360 mL] of beer, 5 ounces [150 mL] of wine, or 1.5 ounces [45 mL] of 80 proof distilled spirits) throughout the study.
(13) Heavy smoker (> 5 cigarettes/day) or the subject could not stop smoking during study period while inpatient at the clinical research center.

Pharmacokinetics
The drug concentration-actual sampling time data of subjects in the Pharmacokinetic (PK) analysis set will be used to compute PK parameters using the standard non-compartmental methods.
Pharmacokinetic biosimilarity between Abcertin and EU-sourced Cerezyme® will be assessed using an ANOVA on the log-transformed parameter. The ANOVA model will contain fixed effects for treatment, period, and sequence, and subjects nested within sequence. The point estimates and 90% confidence intervals (CIs) for the difference among treatments will be calculated. The point estimates and 90% CIs will then be exponentially back transformed to provide point and CI estimates for the ratio of geometric least squares (LS) means for imiglucerase for the following comparisons: Abcertin versus EU-sourced Cerezyme®. PK biosimilarity of Abcertin will be concluded if the 90% CI falls entirely within 80.00% to 125.00% for AUC(0-inf).
As a sensitivity analysis, a similar analysis will be performed using subject within sequence as a random effect instead of as a fixed effect.
Individual secondary PK endpoints stratified by treatments and periods will be listed and summarized in tabular format using descriptive statistics as appropriate. Descriptive statistics for all secondary PK endpoints will include the number of subjects with sufficient data to reliably calculate the selected PK endpoint (N), mean, standard deviation (SD), percent coefficient of variation (%CV), median, minimum and maximum values, geometric mean, and geometric %CV, as appropriate.
In addition, the ANOVA model will also be performed on Cmax and AUC(0-last). As a sensitivity analysis, an additional analysis will be performed using subject within sequence as a random effect instead of as a fixed effect.
Pharmacodynamics:
The number and proportion of positive ADA and NAbs responses will be provided by treatment, visit and sequence. The titer levels (if available) from positive ADA samples assays, will be listed.
Safety:
Descriptive statistics for all safety endpoints will be provided for all treatments including mean, SD, median, minimum and maximum values or by number and proportion, as appropriate. All safety data (scheduled and unscheduled) will be presented in data listings. The number and proportion of subjects experiencing serious and non-serious AEs will be tabulated. Adverse events will be coded according to the Medical Dictionary for Regulatory Activities (MedDRA).
Vital signs, 12-lead ECGs, and clinical laboratory parameters being monitored for safety will be summarized using descriptive statistics by scheduled visit and treatment, and data listings of clinically significant abnormalities/outliers.
Physical examination results will be listed; local injection site tolerance results (pain, redness, itch, bruising, and etc.) will be listed and summarized, as appropriate
