Date of Report (Date of earliest event reported)

Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligations of the registrant under any of the following provisions:

On August 3, 2015, Sophiris Bio Inc. (the “Company”) received a letter from the Listing Qualifications Department of The Nasdaq Stock Market (“Nasdaq”) notifying the Company that the consolidated closing bid price of the Company’s common stock had been below $1.00 per share for 30 consecutive business days and that the Company was therefore not in compliance with the minimum bid price requirement for continued listing on The Nasdaq Global Market, as set forth in Marketplace Rule 5450(a)(1). The notification from Nasdaq does not have an immediate effect on the listing of the Company’s common stock and the Company’s common stock will continue to trade on The Nasdaq Global Market under the symbol "SPHS".

Nasdaq stated in its August 3^rd letter that, in accordance with Marketplace Rule 5810(c)(3)(A), the Company has been provided a grace period of 180 calendar days, or until February 1, 2016, to regain compliance with the minimum consolidated closing bid price requirement for continued listing. Compliance will be regained if the Company’s consolidated closing bid price is at or above $1.00 for at least 10 consecutive trading days anytime during the 180-day grace period.

The Company is considering actions that it may take in response to this notification in order to regain compliance with the continued listing requirements.
