Specific Cobra to private question

In considering whether to go into this MLN trial or onto remi I am wondering how my decision may affect an insurance switch in Aug 2010. My cobra BCBS will be canceled at that time and I'll move onto a private health insurance policy. Exhausting my 18 month benefits I'll be able to get the insurance without the pre-existing condition clause. BUT, at this moment I pretty much have had no prescription meds or doctors visits billed since november of 2008. If I go with remi now, of course there are going to be huge amounts billed to my insurance. I wonder how that will affect my policy premiums, if it would at all next year? If I go back into the MLN trial I will continue to have nothing billed.

Anyone have experience with the switch being on one of the biologics? I know when you sign up they do ask what meds you take.
