I want to say a disease can cause a patient to stop working

[alpacinoutd]

I want to say a disease can cause a patient to stop working. Can I say "derive out of work cycle" or "render out of work cycle"?

Which one is better?

1. With its progress, the disease can render the patient out of the work cycle.

2. With its progress, the disease can derive the patient out of the work cycle.

No, they're both very wrong.

As it progresses, this disease can render the sufferer incapable of working.

As you can see, "render" is OK. "Derive" is totally wrong. You need to look at the definition of that word. "out of the work cycle" is not used. I suppose you could say that the disease can remove someone from the workforce but I don't really like that wording.
