The FDA has recently issued this draft guidance to address clinical pharmacology considerations for peptide drug products. These products fall somewhere between drugs and biologics and do not have the usually well-defined characteristics of either category. A peptide is any polymer with 40 or fewer amino acids.
We wrote about 2023’s Recommended Acceptable Intake Limits for Nitrosamine Drug Substance Related Impurities (NDSRIs) , which also advised on how to review drug products and take appropriate action. First, firms should undertake risk assessments of their APIs, finished products, and products under approved or pending applications.
Finding smallmolecule drugs is much harder than finding a needle in a haystack – discovering the right arrangement of atoms to bind precisely to a protein target to elicit a particular response is a problem of vast dimensionality. Yet the situation with smallmolecules is even worse.
In those with CMT1A, over-production of a protein called PMP22 damages the nerves that supply the arms, hands, legs and feet, leading to muscle weakness or paralysis, problems with balance and loss of sensation. Autophagy boosters, in contrast, are conventional smallmolecule drugs.
We further demonstrate that daily oral treatment with a novel mitofusin activator derived from the natural product piperine can reverse these neurological phenotypes. Here, we describe motor and sensory neuron dysfunction characteristic of clinical CMT type 2A in a CRISPR/Casp-engineered Mfn2 Thr105Met (T105M) mutant knock-in mouse.
