LX4211 is part of a new class of type 2 diabetes agents that inhibit the SGLT2 glucose transporter, thereby blocking reabsorption of glucose that the kidneys have excreted into the urine. However, it is distinct from its predecessors in the class in that it also inhibits SGLT1, another glucose transporter that facilitates the absorption of dietary glucose from the gut.

The regulatory pathway for a competing SGLT2 inhibitor (BMS/AZN' dapagliflozin) has been somewhat rocky and the PDUFA for another of these agents (J&J's canagliflozin) is eminent (March 31, 2013), which should provide important regulatory signals for LX4211 as well.

This report explores the underlying pharmacology of these agents, available clinical data, and the regulatory landscape and its risks. In doing so, it attempts to answer two basic questions: Will LX4211 gain regulatory approval and will it be able to gain market share vs competitors?

Key Topics Covered:

INTRODUCTION

1. Type-2 diabetes
2. Sodium glucose transport (SGLT) inhibition as a new approach to therapy

LX4211 CLINICAL DATA

1. Phase I studies evaluated three forms, dose timing, and drug interactions
2. Study 201 assessed activity over 28 days
3. Study 202: A phase IIb study of LX4211 with metformin background therapy
4. Other studies planned and in progress

CLINICAL AND REGULATORY DISCUSSION

1. What does the pharmacology tell us about potential benefits and risks?

Basic science data illuminate the potential impact of SGLT inhibition
Genetic deletions/mutations of glucose transporters may mimic effects of inhibition

2. Early LX4211 data are consistent with the proposed pharmacology

3. What does dapagliflozin tell us about SGLT2 inhibition and FDA's views?
