A generic drug is identical…to a brand name drug in dosage form, safety, strength, route of administration, quality, performance characteristics and intended use…chemically identical to [the] branded counterpart…
www.fda.gov/drugs/resourcesforyou/consumers/buyingusingmedicinesafely/understandinggenericdrugs/ucm144456.htm
Biosimilars are…highly similar to an already FDA‐approved biological product, known as the biological reference product … [and have] no clinically meaningful differences from the reference product.

How (bio)similar is (bio)similar enough?
12
Not different
Different
• Low resolution analytical methods
• Small sample number (n)
• Higher resolution analytical methods
• Larger sample number (n)
A statistics issue?

Batch vs. continuousBATCH MANUFACTURING
Standard unit operations processing with limited process control
Off‐line testing after each unit operation and for final product
Regular cleaning and sterilization
Familiar
Regulatory acceptability
CONTINU0US MANUFACTURING
Smaller equipment and facilities, reduced capital cost
Process efficiency
Process flexibility
Shorter processing time
Reduced manual handling
In‐line monitoring
Closed loop process control
Real‐time release testing of finished product

What’s a batch?
18
21 CFR 210.3
Batch: a specific quantity of a drug or other material that is intended to have uniform character and quality, within specified limits, and is produced according to a single manufacturing order during the same cycle of manufacture
Lot: a batch, or a specific identified portion of a batch, having uniform character and quality within specified limits; or, in the case of a drug product produced by continuous process, it is a specific identified amount produced in a unit of time or quantity
