NantKwest Inc, a cancer drugmaker that went public last year, gave its chief executive officer Patrick Soon-Shiong a $US147.6 million ($195 million) pay package for 2015, the highest reported by any company so far.

Soon-Shiong's compensation exceeds that granted to Google boss Sundar Pichai, who received $US100.5 million last year to run the search-engine unit of parent Alphabet.

Soon-Shiong, a co-owner of the Los Angeles Lakers basketball team, received stock options valued at $US132.2 million and $US15 million in restricted stock, according to a proxy statement filed on Wednesday.

The options were granted before the company's initial public offering in July, most having a strike price of about $US2. The shares rose 39 per cent to $US34.64 in their first day of trading.
