"With the bulk of the clinical activities for our Dermatology and Ophthalmology studies behind us, we expect in the next 2 to 3 quarters to reduce our cash burn per quarter by $0.5 million - or about 20% - from $2.5 million to about $2 million," said Dr. Geert Cauwenbergh, President and CEO of RXi Pharmaceuticals. He further added that, "The final review of the results of our Phase 2 clinical study with Samcyprone™ in cutaneous warts is almost complete, and these study results will be presented as a poster during the upcoming International Investigative Dermatology meeting on May 18, 2018. We expect that the availability of this clinical data will be helpful in the partnering outreach for our dermatology franchise, and we expect to start the formal partnering process in the next few weeks. Against the back-drop of several partnerships in IO and ACT that we have already announced and expect to expand even further in the current quarter, we feel that RXi is set for some exciting events in the coming few months."

Select First Quarter 2018 Financial Highlights

Cash Position  

At March 31, 2018, the Company had cash of $2.6 million as compared with $3.6 million at December 31, 2017.

On August 8, 2017, the Company entered into a purchase agreement with Lincoln Park Capital Fund, LLC ("LPC"), pursuant to which the Company has the right to sell to LPC up to $15 million in shares of the Company's common stock, subject to certain limitations and conditions set forth therein, over the 30-month term of the purchase agreement. The Company has sold a total of 420,000 shares of common stock to LPC for net proceeds of approximately $1.4 million under the purchase agreement.

On April 9, 2018, the Company entered into a securities purchase agreement with certain institutional and accredited investors relating to the offering and sale of 1,510,604 shares of the Company's common stock at a purchase price of $3.15 per share (the "Offering"). Concurrently with the Offering, the Company also commenced a private placement, whereby it issued and sold warrants exercisable for a total of 1,132,953 shares of common stock, which represents 75% of the shares of common stock sold in the Offering, with a purchase price per share of $0.125 per underlying warrant share and with an exercise price of $3.15 per share (the "Private Placement"). Assuming the warrants are not exercised, net proceeds to the Company from the Offering and Private Placement were approximately $4.1 million after deducting placement agent fees and estimated Offering and Private Placement expenses.


Revenues for the quarter ended March 31, 2018 were $23,000 and related to the work performed by the Company as a sub-awardee under the government grant awarded to our collaborator BioAxone Biosciences, Inc. from the National Institute of Neurological Disorders and Stroke. The Company had no revenues during the quarter ended March 31, 2017.

Research and Development Expenses

Research and development expenses for the quarter ended March 31, 2018 were $1.4 million, as compared with $1.3 million for the quarter ended March 31, 2017. The increase was primarily due to increases in lab supply purchases and manufacturing fees for the Company's immuno-oncology program.

Acquired In-process Research and Development Expense

The Company did not have acquired in-process research and development expense for the quarter ended March 31, 2018. The Company recorded $4.6 million of acquired in-process research and development expense for the acquisition of MirImmune Inc. during the quarter ended March 31, 2017. The expense related to the fair value of consideration given in the acquisition of MirImmune, which included transaction costs, liabilities assumed and cancellation of notes receivable, and the deferred tax impact of the acquisition.

General and Administrative Expenses

General and administrative expense for the quarter ended March 31, 2018 was $0.9 million, as compared with $1.1 million for the quarter ended March 31, 2017. The decrease was primarily due to decreases in professional fees for legal-related services and payroll-related expenses as a result of a decrease in headcount.

Income Tax

There was no income tax expense or benefit during the three months ended March 31, 2018. For the three months ended March 31, 2017, the Company recognized an income tax benefit of $1,621,000 due to the tax-related impact of the Company's acquisition of MirImmune in January 2017.

Net Loss

Net loss for the quarter ended March 31, 2018 was $2.2 million, compared with $5.5 million for the quarter ended March 31, 2017. The decrease was primarily due to in-process research and development expense and income tax benefit recorded during the prior year quarter related to the Company's acquisition of MirImmune, as discussed above.

Select First Quarter 2018 and Recent Corporate Highlights

Select Business and Corporate Highlights


On April 16, 2018, the Company announced that research conducted using its self-delivering RNAi platform in the field of immunotherapy to treat cancer was published in Molecular Therapy, a leading peer-reviewed journal.  

In this paper, scientists demonstrate the potential of improving therapy with patient-derived tumor infiltrating lymphocytes (TILs) by treating with RXi's novel sd-rxRNA compound which specifically targets PD-1. Targeting the PD-1/PD-L1 axis can enhance the ex vivo expansion rate and in vivo longevity and functionality of these T-cells and thereby have the potential to improve Adoptive Cell Therapy (ACT) outcomes in cancer patients.  The sd-rxRNA compounds are based on the proprietary therapeutic platform developed and owned by RXi Pharmaceuticals and are ideally suited to reprogram immune cells used in various forms of ACT.

About RXi Pharmaceuticals

RXi Pharmaceuticals Corporation (NASDAQ: RXII) is a biotechnology company developing the next generation of immuno-oncology therapeutics based on its self-delivering RNAi (sd-rxRNA®) therapeutic platform. The Company's discovery and research efforts are focused on developing sd-rxRNA therapeutic compounds to be used with an Adoptive Cell Transfer (ACT) approach. This process uses immune cells, such as T-lymphocytes that are isolated from the patient or retrieved from allogeneic immune cell banks, and then expanded and in some cases processed to express tumor-binding receptors. Our approach introduces a new and important step in ex-vivo processing of the immune cells where sd-rxRNA is used to eliminate the expression of immunosuppressive receptors or proteins from the therapeutic immune cells, making them less sensitive to tumor resistance mechanisms and thus improving their ability to destroy the tumor cells. Essentially, we aim to maximize the power of our sd-rxRNA therapeutic compounds by weaponizing therapeutic immune effector cells to attack cancer and ultimately provide patients battling terminal cancers with a powerful new treatment option that goes beyond current treatment modalities. For additional information, visit the Company's website,
