NEW MOLECULAR ENTITY AND NEW THERAPEUTIC BIOLOGICAL
PRODUCTS APPROVED FOR 2015
Certain drugs are classified as New molecular Emtities- NME- for FDA review
Many of these products contain active moieties that have not been approved
by FDA previously, either as a single ingredient or as part of a combination
products; these products frequently provide important new therapies for the
patients.
Some drugs are characterized as NMEs for administrative purposes ,but
nonetheless contain certain active moieties in products that have been
previously approved by FDA. For example, CDER classifies biological
products submitted in an application under section 351(a) of the Public
Service Act as NME for purposes of FDA review, regardless of whether
the agency previously approved a related active moiety in a different
product.
FDAs classification of a drug as an -NME- for review purposes is distinct
from FDAs determination of whether a drug is a - New Chemical Entity or - NCE-
within the meaning of the Federal Food,Drug, and Cosmetic Act

Pharmacology/ Pharmacokinetics:
CLINICAL PHARMACOLOGY
1. Mechanism of Action-
Alirocumab is a human monoclonal antibody that binds to proprotein convertase subtilisin kexin type 9 (PCSK9). PCSK9 binds to the low-density lipoprotein receptors (LDLR) on the surface of hepatocytes to promote LDLR degradation within the liver.
LDLR is the primary receptor that clears circulating LDL, therefore the decrease in LDLR levels by PCSK9 results in higher blood levels of LDL-C. By inhibiting the binding of PCSK9 to LDLR, alirocumab increases the number of LDLRs available to clear LDL, thereby lowering LDL-C levels.
2. Pharmacodynamics- Alirocumab reduced free PCSK9 in a concentration-dependent manner. Following a single subcutaneous administration of alirocumab 75 or 150 mg, maximal suppression of free PCSK9 occurred within 4 to 8 hours. Free PCSK9 concentrations returned to baseline when alirocumab concentrations decreased below the limit of quantitation.
3. Pharmacokinetics-
Absorption
After subcutaneous (SC) administration of 75 mg to 300 mg alirocumab, median times to maximum serum concentrations (tmax) were 3-7 days.
The pharmacokinetics of alirocumab after single SC administration of 75 mg into the abdomen, upper arm, or thigh were similar.
The absolute bioavailability of alirocumab after SC administration was about 85% as determined by population pharmacokinetics analysis. A slightly greater than dose proportional increase was observed, with a 2.1- to 2.7-fold increase in total alirocumab concentrations for a 2-fold increase in dose from 75 mg every 2 weeks to 150 mg every 2 weeks.
Distribution
Following IV administration, the volume of distribution was about 0.04 to 0.05 L/kg indicating that alirocumab is distributed primarily in the circulatory system.
Metabolism and Elimination
Specific metabolism studies were not conducted, because alirocumab is a protein. Alirocumab is expected to degrade to small peptides and individual amino acids.
In clinical studies where alirocumab was administered in combination with atorvastatin or rosuvastatin, no relevant changes in statin concentrations were observed in the presence of repeated administration of alirocumab, indicating that cytochrome P450 enzymes (mainly CYP3A4 and CYP2C9) and transporter proteins such as P-gp and OATP were not affected by alirocumab.
Based on a population pharmacokinetic analysis, the median apparent half-life of alirocumab at steady state was 17 to 20 days in patients receiving alirocumab at subcutaneous doses of 75 mg Q2W or 150 mg Q2W
Specific Populations
A population pharmacokinetic analysis was conducted on data from 2799 subjects.
Age, body weight, gender, race, and creatinine clearance were found not to significantly influence alirocumab pharmacokinetics. No dose adjustments are recommended for these demographics.
Pediatric
PRALUENT has not been studied in pediatric patients [see Use in Specific Populations
Renal Impairment
Since monoclonal antibodies are not known to be eliminated via renal pathways, renal function is not expected to impact the pharmacokinetics of alirocumab.
No data are available in patients with severe renal impairment.
Hepatic Impairment
Following administration of a single 75 mg SC dose, alirocumab pharmacokinetic profiles in subjects with mild and moderate hepatic impairment were similar to those in subjects with normal hepatic function.
No data are available in patients with severe hepatic impairment.
Drug-Drug Interactions
The median apparent half-life of alirocumab is reduced to 12 days when administered with a statin; however, this difference is not clinically meaningful and does not impact dosing recommendations.
Pregnancy and lactation:
USE IN SPECIFIC POPULATIONS
1. Pregnancy-
Pregnancy Exposure Registry
There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to PRALUENT during pregnancy. Please contact 1-877-311-8972 or go to https://mothertobaby.org/ongoing-study/praluent/ to enroll in or to obtain information about the registry.
Risk Summary-
There are no available data on use of PRALUENT in pregnant women to inform a drugassociated risk.
In animal reproduction studies, there were no effects on embryo-fetal development when rats were subcutaneously administered alirocumab during organogenesis at dose exposures up to 12-fold the exposure at the maximum recommended human dose of 150 mg every two weeks.
FDA’s experience with monoclonal antibodies in humans indicates that they are unlikely to cross the placenta in the first trimester; however, they are likely to cross the placenta in increasing amounts in the second and third trimester.
Consider the benefits and risks of PRALUENT and possible risks to the fetus before prescribing PRALUENT to pregnant women.
In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively.
2.Lactation Risk Summary-
There is no information regarding the presence of alirocumab in human milk, the effects on the breastfed infant, or the effects on milk production.
3.Pediatric Use-
Safety and efficacy in pediatric patients have not been established.
4. Geriatric Use-
In controlled studies, 1158 patients treated with PRALUENT were =65 years of age and 241 patients treated with PRALUENT were =75 years of age.
No overall differences in safety or effectiveness were observed between these subjects and younger subjects, and other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out.
5. Renal Impairment -
No dose adjustment is needed for patients with mild or moderately impaired renal function. No data are available in patients with severe renal impairment.
6.Hepatic Impairment-
No dose adjustment is needed for patients with mild or moderate hepatic impairment.
No data are available in patients with severe hepatic impairment.
