RXi Pharmaceuticals Regains Compliance with NASDAQ Listing Requirements

MARLBOROUGH, Mass., Jan. 24, 2018

As previously reported, the Company received notification from NASDAQ stating that it was not in compliance with the NASDAQ Stock Market's minimum bid price requirements because the bid price of the Company's common stock had closed below the minimum $1.00 per share for 30 consecutive business days.  Per NASDAQ listing rules, the Company was afforded 180 calendar days, or until August 1, 2017, to regain compliance with NASDAQ listing rules.  Unable to regain compliance by that time, NASDAQ granted the Company an additional 180 calendar days, or until January 29, 2018, to regain compliance with the bid price requirement. 

About RXi Pharmaceuticals

RXi Pharmaceuticals Corporation (NASDAQ: RXII) is a biotechnology company developing RNAi-based immunotherapies to treat cancer. Building on the pioneering discovery of RNAi, scientists at RXi have harnessed the naturally occurring RNAi process which can be used to "silence" or down-regulate the expression of a specific gene that may be overexpressed in a disease condition.  RXi developed a robust RNAi therapeutic platform, including self-delivering RNA (sd-rxRNA®) compounds, that have the ability to highly selectively block the expression of any target in the genome, thus providing applicability to many therapeutic areas. Our development programs include cell-based immunotherapies to treat cancer with a near-term focus on using adoptive cell therapy (ACT).  RXi's extensive patent portfolio provides for multiple product and business development opportunities across a broad spectrum of therapeutic areas, and we actively pursue research collaborations, partnering and out-licensing opportunities with academia and pharmaceutical companies.
