DESIFOR-EXPAND (MHIF)

Summary

The DESIFOR pilot study was conducted to determine the feasibility of utilizing an n-of-1 trial to facilitate tolerance of unblinded rosuvastatin in patients with prior statin intolerance

Detailed Description

Recently developed lipid lowering therapies have been shown to significantly reduce LDL cholesterol and subsequent CVD risk (1, 2). However, they are expensive, and the cost-effectiveness of these medications remains controversial, especially in primary prevention. Novel lipid lowering therapies are frequently considered for individuals with statin intolerance, but payers frequently deny prescription for these medications due to lack of adequate proof of true statin intolerance. How to accurately determine statin intolerance remains a clinical conundrum for both patients and providers. A more scientific, definitive method to determine statin intolerance could potentially allow appropriate, cost-effective use of statin therapy in individuals found to not actually be statin intolerant as well as judicious use of novel medications in patients who are found to truly be statin intolerant. The DESIFOR pilot study was conducted to determine the feasibility of utilizing an n-of-1 trial to facilitate tolerance of unblinded rosuvastatin in patients with prior statin intolerance. The DESIFOR pilot study was a single-center, randomized, double-blinded, n-of-1 trial in patients aged 21 to 79 years and eligible for statin therapy by current guidelines but not on therapy due to intolerance of \>2 statins. Using a double-blinded, N-of-1 randomized trial in patients with previous statin intolerance, \<10% of patients had data suggestive of true statin intolerance, and 2/3 of patients were subsequently able to tolerate 3-months of unblinded treatment with rosuvastatin (3). These data raise the hypothesis that an n-of-1 trial can be used to facilitate tolerance of unblinded rosuvastatin in patients with prior statin intolerance.
