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 PHARMACOLGY-
1.Mechanism of action
Isavuconazonium sulfate is a prodrug of isaconazole and is an anti-fungal
12.3 Pharmacokinetics
General Pharmacokinetics
In healthy subjects, the pharmacokinetics of isavuconazole following oral
administration of CRESEMBA capsules at isavuconazole equivalent doses
up to 600 mg per day (6 capsules) are dose proportional
Based on a population pharmacokinetics analysis of healthy subjects and
patients, the mean plasma half-life of isavuconazole was 130 hours and
the mean volume of distribution (Vss) was approximately 450 L
following intravenous administration
Pregnancy and lactation:
USE IN SPECIFIC POPULATIONS
1. Pregnancy
Pregnancy Category C
There are no adequate and well-controlled clinical studies of CRESEMBA in pregnant
women. CRESEMBA should be used during pregnancy only if the potential benefit
to the patient outweighs the risk to the fetus. Women who become pregnant during
CRESEMBA treatment are encouraged to contact their physician
2.Nursing Mothers
Isavuconazole is excreted in the milk of lactating rats following intravenous
administration. Mothers should not breast feed while taking CRESEMBA.
3. Pediatric Use
The safety and efficacy of CRESEMBA in pediatric patients less than 18 years
of age have not been established.
4. Geriatric Use
Of the 547 patients who received CRESEMBA in the Phase 2 and 3 trials,
86 (16%) of patients were greater than 65 years of age and 20 (4%) were
greater than 75 years of age. The pharmacokinetics of isavuconazole are
comparable in young and elderly subjects (65 years of age and older)
. No dose adjustment of CRESEMBA is needed in elderly patients
