Does The Clinical Research online courses is accreditable?

I have BSc in Pharmacy. I am interested to work in a clinical research field. I read about many online courses in this field like "Kriger's". It will cost around $1000, and I am not sure if it will help me find a good job in research field in international pharmaceutical companies like Pfizer or Abbott. So if anyone of u has an idea , plz I need ur advice. Thank u in advance:)
