Recent Progress and Key Objectives
Commercialization of Iclusig®
Iclusig was re-launched in the U.S. in mid-January with all members of the commercial team in place. Through the first five weeks of commercialization, approximately 180 out of 305 patients from the single-patient IND program have transitioned to commercial supply. We anticipate that approximately 50 additional patients will transition by the end of this quarter.
Additionally, we expect that 7% to 10% of patients from the IND program will remain on Iclusig but will qualify for free drug through our patient assistance program. As expected, the remaining 18% to 20% of patients, predominantly those with advanced phase disease, will discontinue Iclusig from the IND program.
In Europe, we are selling Iclusig in Germany, the United Kingdom, France, Austria and the Netherlands. This year, we will expand commercialization of Iclusig to all of the major markets in Europe – 16 individual countries – based on staged achievement of pricing and reimbursement approvals in each country. We anticipate the majority of the remaining EU pricing approvals will occur in the second half of 2014.
Earlier this month, Iclusig was approved in Switzerland for use in adult patients with all phases of chronic myeloid leukemia (CML) or Philadelphia chromosome-positive (Ph+) acute lymphoblastic leukemia (ALL) for whom treatment with other tyrosine-kinase inhibitors is not appropriate or for patients with the T315I mutation of BCR-ABL. Commercial launch in Switzerland is expected by mid-2014, upon pricing and reimbursement approval.
In January, we announced a distribution agreement with Specialised Therapeutics Australia Pty Ltd (STA) for exclusive rights to commercialize Iclusig in Australia. Under the terms of the agreement, STA will book sales of Iclusig to pharmacies and other distributors, while ARIAD will supply packaged drug to STA. Australian marketing approval and commercial launch of Iclusig are expected in the fourth quarter of this year.
Iclusig Clinical Development
A new clinical trial for Iclusig will begin in the second half of 2014 as part of our FDA post-marketing requirements. This will be a randomized multi-arm trial to characterize several Iclusig doses and to inform its safe use in patients with refractory forms of chronic-phase CML. Importantly, data from this trial will allow physicians to better understand the benefit/risk profile of Iclusig when treatment is started at doses less than 45 mg per day, the currently approved dose in the U.S. and EU.
The Phase 2 trial of Iclusig in patients with gastrointestinal stromal tumors (GIST) is almost fully enrolled, and patient follow up is continuing. We anticipate that the trial will re- open to further patient enrollment upon lifting of the partial clinical hold in the second quarter of this year.
Follow up of patients with resistant or intolerant CML and Ph+ ALL in the Phase 1/2 clinical trial of Iclusig in Japan is ongoing. We plan to file for marketing approval of Iclusig with the Pharmaceuticals and Medical Devices Agency, Japan next year.
Numerous Investigator Sponsored Trials (ISTs) are underway or planned that explore the potential clinical utility of Iclusig in various hematologic malignancies, as well as solid tumors driven by FGFR, RET, and other genetic markers of malignancy.
Clinical data on Iclusig, including data from the front-line EPIC trial and initial Phase 2 data in patients with GIST, have been submitted for presentation to the 2014 annual meeting of the American Society of Clinical Oncology.
Advancing AP26113
Patient enrollment and follow up in the Phase 2 portion of the Phase 1/2 clinical trial of AP26113 are ongoing, and we plan to begin a pivotal Phase 2 trial of AP26113 in ALK+ non-small cell lung cancer (NSCLC) patients resistant to crizotinib later in the first quarter of this year. We expect this trial to be the basis for our initial registration of AP26113.
The planned pivotal trial for AP26113 will be global in design and is expected to enroll approximately 220 patients. All patients in the trial will begin at a dose of 90 mg per day and after one week, will be randomized one-to-one, increasing half of the patients to 180 mg per day, while the other half remain at 90 mg per day. Patients will be evaluated for objective response rate as the primary end-point.
We anticipate presenting clinical updates on AP26113 at the 2014 annual meetings of the American Society of Clinical Oncology and the European Society of Medical Oncology.
Next Oncology Drug Candidate
We expect to nominate a potential best-in-class development candidate in the second half of 2014. This compound is a product of our internal discovery program driven by structure-based drug design. The candidate will be an orally active small-molecule drug, targeted against an oncogenic kinase in a class that is well understood and clinically validated, but with a unique target product profile.
Ridaforolimus
Last week, Merck informed us that it is terminating its license agreement for the global development and commercialization of ridaforolimus, our mTOR inhibitor, in oncology. By the terms of the agreement, this becomes effective in November 2014 at which time all rights related to ridaforolimus in oncology will be returned to ARIAD, creating a new clinical and business opportunity for ARIAD.
Medinol, Ltd. expects patient enrollment to begin imminently in the first of its two registration trials of NIRsupremeTM, its drug-eluting stent system that incorporates ridaforolimus. The commencement of patient enrollment, along with the submission of an investigational device exemption with the U.S. Food and Drug Administration, triggers milestone payments to ARIAD of $3.75 million, with the potential for additional regulatory, clinical and sales milestones, as well as royalties on product sales.
