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. 134 contracts (avg 797 vol/day, 134 traded recently)

RGEN averages only 797 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 $160.00 12-18 call last traded $24.90 on 10/16 (now $25.40/$28.00) — try a limit near $25.40. Also watch the $180.00 11-20 call last traded $12.45 on 10/16 (now $10.50/$12.70) — try a limit near $11.60.
