XHANCE™ (fluticasone propionate) – Future Development
We plan to initiate additional clinical trials of XHANCE in the second half of 2018 to seek a follow-on indication for the treatment of chronic sinusitis. We believe XHANCE would be the first drug therapy product approved for the treatment of chronic sinusitis. Upon approval, we intend to broaden our commercialization efforts to target primary care physicians that we believe treat an additional estimated 6.4 million US patients. If we obtain approval for this indication, we may also direct promotional resources to an additional estimated 20 million adults who are not regularly under the care of physicians for this disease using programs such as direct-to-consumer and direct-to-patient promotion.
We are evaluating the use of our EDS to deliver other drugs or drug combinations, including antibiotics, anticholinergics, antihistamines, mucolytics, leukotriene inhibitors, and other medication classes used to treat diseases primarily managed by ENT and allergy specialists. We have also identified several other product candidates with the potential to leverage our EDS to create clinically differentiated drug treatments for indications such as central nervous system disorders and pain. We will continue to evaluate opportunities to develop product candidates indicated for markets outside of our ENT and allergy focus through business development activities.
