SUNNYVALE, Calif., April 11, 2013 /PRNewswire/ -- Pharmacyclics, Inc. (Nasdaq: PCYC) announced today that the Phase III clinical trial (RESONATE™-2), a monotherapy trial using ibrutinib versus chlorambucil in elderly patients with newly diagnosed chronic lymphocytic leukemia / small lymphocyctic lymphoma (CLL/SLL) has enrolled its fifth patient. The enrollment of the fifth patient has subsequently triggered a fourth $50 million milestone payment obligation from Janssen Biotech, Inc., one of the Janssen Pharmaceutical Companies of Johnson & Johnson, worldwide collaborator on ibrutinib in oncology.
This trial is a randomized, multicenter, open-label Phase III study of ibrutinib (PCI-32765) as a monotherapy versus chlorambucil in patients 65 years or older with treatment-naïve CLL/SLL. The study design is in accord with a Special Protocol Assessment (SPA). The study is designed to demonstrate superiority of ibrutinib with the primary endpoint of progression-free survival (PFS); the comparator is single agent chlorambucil. This global study is planned to enroll 272 patients worldwide.
Further information about this trial can be found at www.clinicaltrials.gov:
NCT01722487 – "A Multicenter, Open-label, Phase 3 Study of the Bruton's Tyrosine Kinase Inhibitor PCI-32765 versus Chlorambucil in Patients 65 Years or Older With Treatment-naive Chronic Lymphocytic Leukemia or Small Lymphocytic Lymphoma (RESONATE™-2)."
About the Janssen Collaboration
As previously announced on December 8, 2011, Pharmacyclics entered into a worldwide collaboration with Janssen to develop and commercialize ibrutinib, a novel, oral, first-in-class Bruton's Tyrosine Kinase (BTK) inhibitor. Pharmacyclics received from Janssen an upfront payment totaling $150 million upon signing the contract. With the dosing of a fifth patient in the RESONATE™-2 study, as announced today, a milestone payment of $50 million has been earned. To date, $200M in milestones have been earned and Pharmacyclics may receive up to an additional $625 million in development and regulatory milestone payments; for total potential upfront and milestone payments of $975 million.
Following regulatory approval, both Pharmacyclics and Janssen will book revenue and co-commercialize ibrutinib. In the US, Pharmacyclics will book sales and take the lead role in US commercial strategy development. Both Pharmacyclics and Janssen will share in commercialization activities. Outside the United States, Janssen will book sales and perform commercialization activities. Profits and losses from the commercialization activities will be split 50/50 on a worldwide basis. Development and commercialization activities under the collaboration will be managed through a shared governance structure. Each company will lead development for specific indications as stipulated in a global development plan. Except in certain cases, in general, development costs are shared on a 40/60 basis (Pharmacyclics 40% and Janssen 60%).
Janssen Biotech, Inc. and Pharmacyclics entered a collaboration and license agreement in December 2011 to co-develop and co-commercialize ibrutinib. Ibrutinib was designed to specifically target and selectively inhibit an enzyme called Bruton's tyrosine kinase (BTK). BTK is a key mediator of at least three critical B-cell pro-survival mechanisms occurring in parallel – regulation of apoptosis, adhesion, and cell migration and homing. Through these multiple signals, BTK regulation helps to direct malignant B-cells to lymphoid tissues, thus allowing access to a micro environment necessary for survival.
The effectiveness of ibrutinib alone or in combination with other treatments is being studied in several B-cell malignancies, including chronic lymphocytic leukemia/small lymphocytic lymphoma, mantle cell lymphoma, diffuse large B-cell lymphoma, follicular lymphoma, Waldenström's macroglobulinemia and multiple myeloma. To date five Phase III trials have been initiated with ibrutinib and a total of 26 trials are currently registered on www.clinicaltrials.gov.
