News Release
INDIANAPOLIS, Ind. — Eli Lilly and Company (NYSE: LLY) announced today it will discontinue development of tabalumab — being studied for the treatment of systemic lupus erythematosus (SLE, commonly known as lupus) — due to insufficient efficacy in two pivotal Phase 3 trials. The decision was not based on safety concerns.
In the ILLUMINATE 1 study, tabalumab did not achieve the primary endpoint, at either dose studied, of statistically significant improvement on SRI-5 (SLE Responder Index-5, a measurement of lupus disease activity and response), compared to standard of care therapy. In ILLUMINATE 2, the higher dose of tabalumab met this endpoint, the first time a lupus study has achieved this efficacy measure as a primary endpoint in a Phase 3 trial. Collectively, the data from these studies did not meet expectations for efficacy in the context of existing treatments. The overall safety profile showed a similar frequency of adverse events in patients treated with either tabalumab or standard of care. Lilly intends to submit these data for disclosure in appropriate upcoming scientific venues.
Given the overall efficacy results from these two pivotal Phase 3 studies, Lilly will not move forward with submissions to global regulators. Lilly will work with investigators to appropriately conclude these studies in the interest of patient safety.
“Although we were pleased that tabalumab met the criteria for statistically significant improvement in the SRI-5 endpoint in one of our trials, we are nonetheless disappointed that the overall results did not meaningfully improve the condition of the patients in these studies,” said J. Anthony Ware, M.D., Senior Vice President, Product Development, Lilly Bio-Medicines. “The ILLUMINATE trials are the largest Phase 3 clinical studies in lupus to date, and we are hopeful that our contribution of the extensive data from these studies will advance knowledge to enhance treatment in this devastating illness. Lilly remains committed to developing potential new medicines for the treatment of autoimmune conditions, including lupus.”
The decision to discontinue development of tabalumab for lupus is expected to result in a third-quarter charge to research and development expense of up to $75 million (pretax), or approximately $0.04 – $0.05 per share (after-tax).
