DHHS Guidelines Highlight Importance of Achieving Suppression When Choosing New ARV Agents1
ARV regimen considerations for treatment-experienced patients

suppression is essential
The primary goal of treatment for ART-experienced patients with drug resistance experiencing virologic failure is to establish suppression.

Potency is critical
For patients with virologic failure, consider expected potency of additional agent(s), taking into account the patient's ART history, resistance, and availability of a new MOA.

INCLUDES 2-3 FULLY ACTIVE AGENTS
A new regimen should include at least 2 fully active agents if at least one has a high resistance barrier, and 3 fully active agents if no agent with a high resistance barrier is available for use.

Beware of cross-resistance
The use of a new drug does not ensure that it will be fully active due to the potential for cross-resistance among drugs from the same class.
