Argos Therapeutics Reports Second Quarter 2014 Financial

DURHAM, N.C., Aug. 13, 2014 (GLOBE NEWSWIRE) -- Argos Therapeutics, Inc. (Nasdaq: ARGS ), a biopharmaceutical company focused on the development and commercialization of fully personalized immunotherapies for the treatment of cancer and infectious diseases using its Arcelis™ technology platform, today reported financial results for the second quarter ended June 30, 2014, and provided an update on the Company's clinical programs.

"We continue to be pleased with the progress we are making in our ADAPT phase 3 trial of AGS-003 in metastatic renal cell carcinoma (mRCC), as we now have collected tumors for screening for eligibility from more than half of the patients we believe are needed to complete enrollment," said Jeff Abbey, president and chief executive officer. We are also encouraged by the survival data from our completed phase 2 trial of AGS-003 in mRCC that were presented at the ASCO Annual Meeting in May 2014, which showed a median long-term survival of 57 months in 11 intermediate risk mRCC patients. We plan to initiate phase 2 clinical trials of AGS-003 in early stage RCC, non-clear cell mRCC, and other solid tumors later this year."

Mr. Abbey continued, "We are also encouraged by the data we recently presented at the International AIDS Society Symposium from our completed phase 2 trial of AGS-004 in which viral load control was associated with low viral sequence diversity indicating that AGS-004 decreased viral replication in patients in the trial. In May 2014, stage 1 of an investigator-initiated phase 2 clinical trial of AGS-004 aimed at HIV eradication was initiated; in stage 2 of the trial, a latency reversing drug will be introduced in combination with AGS-004. Finally, we look forward to sharing key data from our phase 2b clinical trial of AGS-004 in chronically infected HIV patients in the coming weeks. We hope these data will further validate the ability of our Arcelis technology platform to induce memory T cell responses."

Recent Highlights and 2014 Anticipated Milestones

AGS-003 Program

• Phase 3 ADAPT clinical trial in mRCC:
  • Over 130 active clinical sites
  • Collected tumor from approximately 530 patients for screening for eligibility as of July 31, 2014
  • Enrolled and randomized approximately 190 patients in the clinical trial as of July 31, 2014
  • On track to complete tumor collection by the end of 2014 and to complete enrollment and randomization in the first quarter of 2015
• Long-term survival data from the completed phase 2 clinical trial and an update on the ongoing phase 3 ADAPT clinical trial were presented during poster sessions at the 50th Annual Meeting of the American Society of Clinical Oncology (ASCO) in Chicago, IL
  • Results presented on May 30, 2014, demonstrated that 11 intermediate risk mRCC patients treated with AGS-003 and sunitinib had a median overall survival of 57.1 months (recent findings from a pooled analysis of six phase 2 and phase 3 clinical trials presented during the 2014 Genitourinary Cancers Symposium indicated that the median overall survival for 548 intermediate risk mRCC patients treated with sunitinib was 20.5 months), with 23 percent of all patients surviving for more than five years as of the time of data presentation, including two patients in long-term remission. Median overall survival for all 21 patients in the trial was 30.2 months. In published findings from the International mRCC Database Consortium, the median overall survival for 1,189 similar risk mRCC patients who were treated with sunitinib was 14.7 months
• Phase 2 clinical trials in early stage RCC, non-clear cell mRCC and other solid tumors planned to initiate by the end of this year

AGS-004 Program

• Data presented at the International AIDS Society Towards an HIV Cure Symposium in Melbourne, Australia in July, demonstrated that viral load control was associated with low viral sequence divergence indicating that AGS-004 administration may limit virus evolution by inhibiting replication. The data were from a follow-up sub-study from the AGS-004 phase 2 clinical trial designed to assess the impact of AGS-004 during a 12-week analytical treatment interruption in chronic HIV-1-infected subjects
• Stage 1 of an investigator-initiated phase 2 clinical trial aimed at HIV eradication in adult patients initiated in May 2014; in stage 2 of the trial, a latency reversing drug will be introduced in combination with AGS-004
• Key phase 2b clinical trial data, including measurement of immune response and HIV replication during analytical treatment interruption, expected in the coming weeks
• Phase 2 clinical trial for elimination of antiretroviral therapy in pediatric patients planned to initiate later this year

Second Quarter 2014 Financial Results

Net loss attributable to common stockholders for the three months ended June 30, 2014 was $12.0 million, or $0.61 per share, compared to a net loss attributable to common stockholders of $5.8 million, or $25.53 per share, for the same period in 2013. Net loss attributable to common stockholders for the six months ended June 30, 2014 was $22.8 million, or $1.52 per share, compared to a net loss attributable to common stockholders of $10.3 million, or $45.44 per share, for the same period in 2013. The net loss per common share during the three and six month periods ended June 30, 2013 was higher than during the same periods in 2014 due to a significantly lower number of weighted average shares outstanding during 2013 prior to our initial public offering in February 2014.

Revenue for the three months ended June 30, 2014 totaled $0.5 million compared to $1.3 million for the same period in 2013. Revenue for the six months ended June 30, 2014 totaled $1.3 million compared to $2.7 million for the same period in 2013.

Research and development expense for the three months ended June 30, 2014 totaled $10.6 million compared to $6.1 million for the same period in 2013. Research and development expense for the six months ended June 30, 2014 totaled $19.0 million compared to $11.3 million for the same period in 2013.

General and administrative expense for the three months ended June 30, 2014 totaled $1.9 million compared to $0.9 million for the same period in 2013. General and administrative expense for the six months ended June 30, 2014 totaled $3.8 million compared to $2.0 million for the same period in 2013.

As of June 30, 2014, Argos' cash, cash equivalents and investments totaled $71.8 million compared to $47.0 million as of December 31, 2013.

"We ended the second quarter of 2014 in a strong financial position," said Lori Harrelson, vice president of finance. "We expect that our existing cash, cash equivalents and short-term investments, including anticipated funding under our NIH contract, will enable us to fund operating expenses into the second half of 2016, including funding our ADAPT phase 3 clinical trial of AGS-003 through data, the planned phase 2 clinical trials of AGS-003, and certain of the costs of our ongoing and planned phase 2 clinical trials of AGS-004."

About the Arcelis™ Technology Platform

Arcelis is a fully personalized immunotherapy technology that captures mutated and variant antigens that are specific to each patient's disease. It is designed to overcome immunosuppression by producing a durable memory T cell response without adjuvants that may be associated with toxicity. The technology is potentially applicable to a wide range of different cancers and infectious diseases and is designed to overcome many of the manufacturing and commercialization challenges that have impeded other personalized immunotherapies.

The Arcelis process uses only a small tumor or blood sample and the patient's own dendritic cells, which are collected and optimized following a single leukapheresis procedure. The proprietary process uses RNA isolated from the patient's disease sample to program dendritic cells to target disease antigens. The activated, antigen-loaded dendritic cells are then formulated into the patient's plasma and administered via intradermal injection.
