Historical option prices for this thinly-traded ticker. Live quotes are wide and stale — use where each contract actually traded plus its 30-day range to place a limit order. 145 contracts (avg 275 vol/day, 144 traded recently)

RGEN averages only 275 option contracts/day, so quotes are thin and bid/ask spreads run wide. Use the last actually-traded price below to set a limit order rather than chasing the displayed ask. Most tradeable call: the $180.00 09-18 call last traded $6.90 on 08/21 (now $7.90/$10.70) — try a limit near $7.90.
