Hollis-Eden, a small biotech company in San Diego, California, is developing a new class of drugs derived from a master hormone that helps run the immune system.

The first of these is called HE2000. A university study in Thailand shows it can help cure malaria. There is good reason to think it could also treat HIV illness, but we may never know because unlike an antiviral, there is no laboratory test that can be used to show the FDA that the drug is effective.
