Yep. I'd have to dig for examples, but many cancer drugs have different efficacies on differing ethnic populations. My father researches genetic markers vs. success rates in different treatments for the same types of cancer. He sees it constantly (Dinner conversation; his big data vs my big data). It's easy enough to assume they do given the different rates of diseases among ethnic groups. From my viewpoint, I would be more shocked if they did actually have the same efficacy.
