NeoPharm Announces Execution of a Letter of Intent with SIRO Clinpharm (India) for a Planned Confirmatory Phase III Trial for Cintredekin Besudotox (IL13-PE38QQR)

Published: May 22, 2008

LAKE BLUFF, Ill.--(BUSINESS WIRE)--NeoPharm, Inc. (NASDAQ: NEOL - News) today announced that it has signed a letter of intent with SIRO ClinPharm USA (“SIRO”) with regard to SIRO’s engagement to oversee a planned confirmatory Phase III trial for its drug product candidate Cintredekin Besudotox (IL13-PE38QQR) (“IL-13”), for the treatment of patients suffering from Recurrent Glioblastoma Multiforme (GBM).

“Over the last year, we have completed an extensive evaluation of IL-13 for the treatment of GBM, and believe that the value and opportunity of this drug candidate merits the commencement of a confirmatory Phase III trial,” commented Mr. Laurence Birch, President and Chief Executive Officer of NeoPharm Inc. “We are on a clear path of clinical development with the announcement of several new trials over the last two months and are encouraged by our progress to date. Going forward, we will continue to identify opportunities to further extract value from our robust drug candidate pipeline.”

Dr. Aquilur Rahman, the Company’s Chief Scientific Advisor commented, “This confirmatory Phase III trial is designed with a primary objective of determining Overall Survival, as well as a secondary objective of determining Progression Free Survival, or PFS. We will monitor the Phase III confirmatory trial to determine if there is any advantage of PFS duration in these patients with IL-13. We believe that if any significant advantage of PFS for patients treated with IL-13 compared to the standard of care in GBM is demonstrated, that such evidence may be taken into consideration for possible regulatory approval of IL-13. In addition, we will monitor the delivery system with an imaging agent to ensure that tumor areas in the brain are fully impregnated with drug to provide the full therapeutic benefit of this very active agent for GBM. These trials will be performed in consultation with the FDA.”

This Phase III trial is projected to enroll a total of 45 patients beginning by the fourth quarter of calendar 2008. NeoPharm anticipates that this Phase III trial will generate substantial data by the end of calendar year 2009. The Company will evaluate the results from such a confirmatory trial to decide whether to expand the Phase III trial into a multinational, multicenter trial to increase the patients’ database, with the goal of satisfying the FDA’s requirements for a Cintredekin Besudotox BLA submission.

"We welcome the opportunity to help NeoPharm conduct this complex oncology trial in India, where we believe IL-13 will be most likely to demonstrate significant benefits for patients with GBM. Our goal is to help bring such life-prolonging therapies to the market as quickly as possible by developing the high-quality data that is required by the FDA, EMEA and other global regulatory agencies," commented Dr. Mark Bradshaw, President of SIRO ClinPharm USA.

Under the terms of the binding letter of intent, NeoPharm and SIRO have agreed to negotiate in good faith the terms of a clinical research agreement pursuant to which SIRO would provide clinical research oversight of the Phase III confirmatory trial in India.
