CytRx Corporation Reports 2015 Second Quarter Financial Results

LOS ANGELES, Aug. 3, 2015 /PRNewswire/ -- CytRx Corporation (NASDAQ: CYTR), a biopharmaceutical research and development company specializing in oncology, today reported financial results for the three months ended June 30, 2015, and also provided an overview of recent accomplishments and upcoming milestones for its clinical development programs.

"The second quarter of 2015 has been very productive for CytRx. Enrollment in our ongoing pivotal global Phase 3 clinical trial of aldoxorubicin in soft tissue sarcoma (STS) continues on track to be completed in the first quarter of 2016. On the financial front, we successfully closed a public equity offering raising an additional $28.8 million in gross proceeds, which significantly strengthens our balance sheet and allows us to further advance the aldoxorubicin program, provide for pre-commercialization launch expenses, and introduce our next generation of therapies into the clinic in 2016," said Steven A. Kriegsman, Chairman and CEO of CytRx. "The second quarter also included the announcement of promising updated data from our Phase 2 programs evaluating aldoxorubicin in Kaposi's Sarcoma (KS) and glioblastoma (GBM), in addition to compelling data in our two combination trials."

Mr. Kriegsman continued: "We were also pleased to recently unveil our proprietary LADR (Linker Activated Drug Release) technology platform which will be used for the development of our next-generation therapeutic drug conjugates which we may employ as treatments for liver, pancreatic, and non-small cell lung cancers, among others. These conjugates, developed at our laboratory facilities in Freiburg, Germany, will be designed to control release in tumors of high-potency chemotherapeutics that are attached to either albumin or anti-cancer antibodies. We believe this proprietary platform is highly complementary to and builds upon our ongoing global Phase 3 aldoxorubicin program."

Second Quarter 2015 and Recent Highlights

Strengthened the Corporate Balance Sheet. In July 2015, CytRx successfully completed a public offering of common stock securing gross proceeds of approximately $28.8 million. CytRx intends to use the net proceeds of the offering to fund clinical trials of its drug candidate aldoxorubicin and its drug discovery activities and for general corporate purposes, which will include pre-commercialization activities relating to aldoxorubicin, working capital and capital expenditures.

Unveiled proprietary LADR (Linker Activated Drug Release) Technology Platform. In June 2015, CytRx announced its proprietary LADR technology platform, a discovery engine designed to leverage the Company's expertise in albumin biology and linker technology for the development of a new class of anti-cancer therapies. CytRx expects the LADR platform to rapidly expand its pipeline of oncology drug candidates, providing an avenue for the development of propriety therapies that complement its global Phase 3 aldoxorubicin program. Among the cancers being pursued are liver, pancreatic, and non-small cell lung cancer.

Reported Interim Phase 2 Data for Aldoxorubicin for HIV-Related Kaposi's Sarcoma. In June 2015, at the 18th International Workshop on Kaposi's Sarcoma Herpesvirus (KSHV) and Related Agents in Hollywood, Florida, CytRx reported interim results from its ongoing open-label Phase 2 pilot study evaluating the efficacy and safety of aldoxorubicin for the treatment of Kaposi's Sarcoma (KS) in HIV-infected patients. The preliminary analysis from nine patients who received at least six cycles of aldoxorubicin (mean = 6.3 cycles), four of whom had received prior Doxil® chemotherapy, showed six (67%) demonstrated a partial response (PR) to aldoxorubicin at the end of study visit (EOS), and 7 (78%) demonstrated PR within 4 months of EOS. Most importantly, doxorubicin could be detected in all tumor biopsies and higher doxorubicin concentrations were demonstrated within KS lesions relative to skin next to the lesions for 3/4 (75%) patients for whom adequate tissue was available for analysis. Five of 6 (83%) patients receiving aldoxorubicin and for whom data are available exhibited reduced intratumoral viral loads during therapy. A subset of patients also exhibited improvements in quality of life during treatment, and all patients exhibited either improvement or stability in immunologic and virologic HIV treatment parameters.

Strengthened the Leadership Team. In June 2015, CytRx appointed Cheryl Cohen to its Board of Directors. Ms. Cohen served as the Chief Commercial Officer of Medivation, Inc., from September 2011 to July 2014, where she built the company's commercial framework and led its successful launch of Xtandi® in the United States. Her experience will be highly valuable as the Company prepares for the commercialization of aldoxorubicin.

Reported Aldoxorubicin Cardiotoxicity Data in a Poster Presentation at the 2015 American Society of Clinical Oncology (ASCO) Annual Meeting. In May 2015, in a poster presentation at ASCO, CytRx reported cardiotoxicity data from 200 patients across 7 clinical trials (1 Phase 3, 3 Phase 2 and 3 Phase 1) evaluating aldoxorubicin. The results showed that none of the patients exhibited a decrease in left ventricular ejection fraction (LVEF) that was below 50% of their institution's normal value.  14% of patients demonstrated a 10% drop in LVEF and 21% had a 10% increase in LVEF. Other side effects observed were consistent with effects seen in other anthracycline treatments. Patients in these trials have received up to 5,439 mg/m2 of doxorubicin equivalents, or 12 times the peak cumulative dose of standard doxorubicin, without any evidence of cardiotoxicity. These results suggest that aldoxorubicin can be safely administered at cumulative doses of over 2 g/m2 without evidence of cardiotoxicity.

Reported Positive Updated Phase 2 Aldoxorubicin Clinical Trial Results in Glioblastoma Multiforme (Brain Cancer). In May 2015, CytRx reported positive updated data from its open-label, multisite trial in evaluating the preliminary efficacy and safety of aldoxorubicin in patients whose tumors have progressed following prior treatment with surgery, radiation and temozolomide. The updated trial results in 18 patients showed three pathological complete responses, as well as tumor shrinkage and prolonged stable disease. Aldoxorubicin was also well tolerated.

Reported Positive Interim Results from two Phase 1b Aldoxorubicin Trials in Chemotherapy Resistant Cancers. In May 2015, the Company announced positive interim results from its two ongoing Phase 1b clinical trials evaluating aldoxorubicin in chemotherapy resistant cancers. Interim results from seven patients in the first study, evaluating the preliminary safety and activity of ascending doses of aldoxorubicin plus ifosfamide/mesna for the first-line treatment of patients with locally advanced, unresectable, and/or metastatic sarcomas, show that the combination of aldoxorubicin plus ifosfamide/mesna was well tolerated, with one bone cancer patient achieving a complete tumor response (as assessed by PET/CT scan) following five treatment cycles. Interim results from seven patients in the second study, evaluating the preliminary safety and activity of ascending doses of aldoxorubicin plus gemcitabine in patients with advanced, unresectable, metastatic solid tumors that have either relapsed or were refractory to treatment following at least one prior chemotherapy or immunotherapy regimen, show that the combination of aldoxorubicin plus gemcitabine was well tolerated, with tumor shrinkage observed in three of seven patients following two treatment cycles. One patient with a history of chronic severe pain and inability to function normally demonstrated meaningful quality of life improvements, including stopping prescription narcotic pain medications and returning to work full-time. These results suggest that aldoxorubicin in combination with other chemotherapeutic agents has the potential to bolster anti-cancer activity.

Announced the Publication of a Clinical Case Study of Aldoxorubicin in Glioblastoma.  In April 2015, the Company announced the publication of a case study, titled "Albumin-Linked Doxorubicin (Aldoxorubicin) as Treatment for Relapsed Glioblastoma: A Case Report," in the Journal of Nuclear Medicine & Radiation Therapy. In a 54 year old male patient with recurrent left parietal lobe glioblastoma multiforme (GBM) who was administered a single cycle of intravenous aldoxorubicin 350 mg/m² (260 mg/m² doxorubicin equivalents), histopathological assessment of tissue following a subsequent tumor debulking procedure showed no evidence of recurrent glioblastoma throughout the entire surgical specimen. These findings suggest that aldoxorubicin allows doxorubicin to cross the tumor's blood-brain barrier in humans and induce tumor necrosis (tumor cell death).

Second Quarter 2015 Financial Results

CytRx reported cash, cash equivalents and short-term investments of $53.8 million as of June 30, 2015.

Net loss for the three months ended June 30, 2015 was $11.7 million, or $0.21 per share, compared with a net loss of $15.7 million, or $0.28 per share, for the three months ended June 30, 2014. The decrease of $4.0 million in net loss during the current three-month period resulted primarily from a gain of $2.4 million on warrant derivative liability in the current quarter, as compared to a loss on warrant derivative liability of $2.5 million in the comparative 2014 period, for a difference of $4.9 million.

Research and development (R&D) expenses were $10.0 million for the second quarter of 2015, and included development expenses of $8.2 million for aldoxorubicin. The remaining $1.8 million of R&D expenses were primarily related to research and development support costs. R&D costs were $10.4 million for the second quarter of 2014.

General and administrative (G&A) expenses were $4.2 million for the second quarter of 2015, compared with $2.9 million for the second quarter of 2014. G&A expenses for the second quarter of 2015 included non-cash employee stock-compensation expense of $1.7 million, compared to $0.3 million for the same period in 2014.

About Soft Tissue Sarcoma

Soft tissue sarcoma is a cancer occurring in muscle, fat, blood vessels, tendons, fibrous tissues and connective tissue, and can arise anywhere in the body at any age. According to the American Cancer Society, there are approximately 50 types of soft tissue sarcomas. In 2013 more than 11,400 new cases were diagnosed in the U.S. and approximately 4,400 Americans died from this disease. In addition, approximately 40,000 new cases and 13,000 deaths in the U.S. and Europe are part of a growing underserved market.

About SCLC

An estimated 1.6 million new cases of lung cancer are diagnosed worldwide each year.  In the Western world, approximately 13-15% of cases are SCLC, a deadly form of lung cancer associated with tobacco use.  The five year survival rate is less than 7%, in part because an estimated 70% of patients have extensive disease at diagnosis.  According to the National Cancer Institute, more than 30,000 new cases will be diagnosed in the USA in 2014.  The estimated 2014 SCLC incidences for Europe and Asia are over 58,000 and 136,000, respectively.

About Glioblastoma Multiforme

Glioblastoma is the most common and most malignant primary brain tumor in adults and afflicts more than 12,000 new patients in the U.S. annually.  The median survival after diagnosis is approximately 14 months, despite patients subsequently receiving surgical resection, radiotherapy and chemotherapy.  Limited efficacy of chemotherapeutic agents has been attributed to several contributing factors including insufficient drug delivery to the tumor site through the blood:brain barrier.

About Kaposi's Sarcoma

Kaposi sarcoma is a cancer that causes lesions (abnormal tissue) to grow in the skin; the mucous membranes lining the mouth, nose, and throat; lymph nodes; or other organs. The lesions are usually purple and are made of cancer cells, new blood vessels, red blood cells, and white blood cells. Kaposi sarcoma is different from other cancers in that lesions may begin in more than one place in the body at the same time. KS remains the most common HIV-associated tumor worldwide. The condition is also endemic in certain parts of Central Africa and Central and Eastern Europe.

About Bone Cancers (Osteosarcoma, Chondrosarcoma)

Bone cancer is a highly aggressive type of cancer that develops in bone.  It starts in immature bone cells (osteoblasts) that normally form new bone tissue.  According to the National Cancer Institute, there are approximately 3400 new cases of bone and joint cancer diagnosed each year in the United States, with approximately half of these occurring in children and teens.  In addition, the estimated deaths in the U.S. were 1,460 in 2014.  Although they can arise in any bone in the body, the most frequent sites are at the ends of the long bones of the legs and arms.  In most cases, treatment consists of both chemotherapy and surgery, but patients with metastatic bone cancer continue to have a poor 5-year survival rate (15-30%).

About Aldoxorubicin

The widely used chemotherapeutic agent doxorubicin is delivered systemically and is highly toxic, which limits its dose to a level below its maximum therapeutic benefit. Doxorubicin also is associated with many side effects, especially the potential for damage to heart muscle at cumulative doses greater than 450 mg/m2. Aldoxorubicin combines doxorubicin with a novel single-molecule linker that binds directly and specifically to circulating albumin, the most plentiful protein in the bloodstream. Protein-hungry tumors concentrate albumin, thus increasing the delivery of the linker molecule with the attached doxorubicin to tumor sites. In the acidic environment of the tumor, but not the neutral environment of healthy tissues, doxorubicin is released. This allows for greater doses (3 ½ to 4 times) of doxorubicin to be administered while reducing its toxic side effects. In studies thus far there has been no evidence of clinically significant effects of aldoxorubicin on heart muscle, even at cumulative doses of drug well in excess of 2,000 mg/m².
