Update - They're now testing an oral form (Alferon LDO) currently in Phase 2 trials for HIV.
My guess is Alferon was so successful at things they never dreamed of, that they pulled it to rerelease at higher cost.
Below is/was approved off label uses. I asked a hema/oncologist if he knew of any ONE drug for all listed. He said no. This is alfa, this one beta, these alfa, this one gamma. He told me their nasty drugs too for side effects. The person I know that took it hasnt returned my calls in months. I never got side effect info from him.

chronic hepatitis c
hairy cell leukemia
malignant melanoma
aids-related Kaposi's disease
bladder cancer
carcinoid syndrome
renal cancer
multiple myeloma
ovarian cancer

The co. told me it was one issue, I called fda they said no issues on our end.
Had fda call them and they got different answer.
I called again months later and they told me dea issue.
I havent given up yet. Emailed the lady running trails but no reply. Will call.
Its scarry that a genitle herepes warts drug worked and now its being tried for HIV but this leads me to wonder if an existing HIV or herpes drug would have similar effect.
