iCo Therapeutics iCo-007 Phase I Clinical Trial Meets Primary Endpoint

May 17, 2010

 

VANCOUVER, Canada— iCo Therapeutics Inc. (TSX-V: ICO) is pleased to announce that its Phase I clinical trial for iCo-007 in patients with diffuse diabetic macular edema has met its primary end point. The primary objective of the phase I, open-label, dose escalation trial was to evaluate the ocular safety and tolerability of iCo-007 following a single intravitreal administration.  Secondary objectives included assessment of systemic pharmacokinetics, retinal thickness using optical coherence tomography (OCT) measurements, and visual acuity.

The Phase I trial was conducted at four clinical sites in the United States administering a single injection of iCo-007 in patients with diffuse diabetic macular edema and involved a 24 week follow-up period.  Four dosage levels of iCo-007 were utilized in a total of 15 patients.  iCo-007 was administered as an intravitreal injection with  doses of either  110 ug, 350 ug, 700 ug, or 1000 ug.  

Intravitreal injections of iCo-007 were well tolerated with a good safety profile, ultimately progressing to the highest dose of 1000 µg based on positive safety evaluation committee meetings two months post each dosing level. Analysis of blood plasma in patients demonstrated that iCo-007 was not detectable in the blood plasma with any of the doses used in the Phase I trial. There were signs of biological activity in responsive patients at 24 weeks with a reduction of retinal thickness ranging between 149 and 743 microns (and 115 to 743 microns if one additional patient followed only to week 18 is included).  Mean change in retinal thickness for all patients completing the 24 week follow-up (12 of 15 patients) was minus 169 microns (or 40% reduction of excess retinal thickness), a positive trend.  In a number of subjects there was a transient increase in retinal edema preceding biological effect.  Approximately 69% of patients completing a 24 week follow up (13 of 15 patients) had stable or improved vision, defined as -5 letters or better compared to baseline and 23% of patients experienced greater than or equal to 5 letters of visual improvement.  The highest dose seemed to show a smaller biological effect than lower doses. The first three doses appeared to display some dose-related biological effect, warranting further exploration of dosing and treatment regimen in a Phase II clinical trial.

"We are extremely pleased that iCo-007 successfully met the primary endpoint for our Phase I trial", commented Andrew Rae, iCo's President and CEO. "In addition, we have seen signs of biological activity in a very difficult to treat patient population refractory to many other treatments, including anti-VEGF agents in some cases. The safety and secondary endpoint information we have gleaned from this trial, including the biological activity we have seen at various dose levels, will be extremely useful and fully supports advancing to a Phase II clinical trial program which is currently in the planning stage". 

About Diffuse DME

DME is the swelling of the retina in diabetes patients due to leaking blood vessels within the macula, the central portion of the retina that is critical for daytime vision. Diffuse DME is caused by dilated retinal capillaries and it is typically more difficult to handle than focal DME.  There are currently no approved therapeutics for DME, the leading cause of blindness in working age adults. DME affects approximately 1.6 million people in the U.S. alone, a number that is expected to grow as Diabetes is forecast to increase by almost 50% in the US by 2025. 

About iCo-007

Designed and discovered by ISIS Pharmaceuticals Inc., (NASDAQ: ISIS), iCo-007 is a second-generation antisense drug targeting c-Raf kinase for the treatment of DME and diabetic retinopathy.
