I suspect that the initial studies will narrow the therapeutic choices. Medical studies do this and if approved it will be for sarcoidiosis and/or diabetic neuropathy.

If this happens, the FDA will approve for only the minimum parameters. The insurance then will only pay for this new drug for those parameters.

Lidoderm patches were only paid for post herpetic neuralgia, with previous occurring shingles. I was lucky to have had shingles, and testing for them, so I could use the patches for my MP pain. ( and also other nerve PN issues). Now of course, the new OTC lidocaine patches anyone can buy without a Dr's order.
The OTC ones are 4% and the older RX ones are 5%.

The lidocaine patches RX were over 300.dollars out of pocket for a month's supply!
That was many years ago... and I'd expect this ARA drug to be much more.

Here is an example of a new drug for HAE which I was diagnosed with 3 yrs ago...
Cinryze, a Human Plasma-Derived C1 Esterase Inhibitor for Prophylaxis Of Hereditary Angioedema

I have 2 attacks per month on average, and this would be more than $5,000 if my insurance would cover it. I have not decided to use this injectable, and am waiting for an oral type. If I have a breathing attack that decision will change for me. This is just an example of costs for new meds.
