Nektar Therapeutics, a Delaware corporation
(“Nektar”), has royalty rights to Bayer AG’s (“Bayer”) Ciprofloxacin Dry Powder for Inhalation (DPI)
drug candidate. Bayer has sole responsibility for all aspects of the development and commercialization of Ciprofloxacin DPI.
The Phase III clinical
trial program for Ciprofloxacin DPI, called RESPIRE, was designed and conducted solely by Bayer and was comprised of two pivotal
trials with identical study designs to evaluate the efficacy and safety of Ciprofloxacin DPI in adult patients with non-cystic
fibrosis bronchiectasis (NCFB). The data from RESPIRE 1 were presented at the 26
th
International Congress of European
Respiratory Society in September 2016. In the 14 days on/off regimen, the RESPIRE 1 trial met its primary endpoints of significantly
prolonged time to first exacerbation and significantly reduced frequency of exacerbations versus placebo. On April 5, 2017, an
abstract with data from the RESPIRE 2 trial was published by the American Thoracic Society in connection with the American Thoracic
Society 2017 International Conference. The abstract had been previously submitted by Bayer in accordance with ATS submission guidelines.
The RESPIRE 2 trial showed a positive trend of Ciprofloxacin DPI efficacy for both the 14 and the 28 days on/off regimens, but
did not reach statistical significance. A pooled analysis of the primary efficacy results of RESPIRE 1 and RESPIRE 2 is positive.
The data of both RESPIRE 1 and RESPIRE 2 indicated that Ciprofloxacin DPI has a positive safety profile. Top-line results of RESPIRE
2 will be presented at the upcoming American Thoracic Society 2017 International Conference.
Patients with NCFB
suffer from frequent and severe exacerbations of their disease, so there is a significant unmet medical need for long-term treatment
options. Bayer has informed us that they plan to discuss next steps with regulatory authorities on the basis of the findings from
RESPIRE 1 and RESPIRE 2.
SIGNATURES
Pursuant to the requirement of the Securities Exchange
Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned thereunto duly authorized.
