CytRx Issues Letter to Stockholders Providing Business Update

(NASDAQ:CYTR), a biopharmaceutical research and development company specializing in oncology, announced the issuance of its annual Letter to Stockholders from President and CEO Steven A. Kriegsman. The Letter provides an overview of the Company’s business plan and is available on the Company’s website at . Excerpts from the Letter are as follows:

To Our Valued Stockholders and Friends:

The coming year promises to be highly eventful as we look forward to reporting data from three clinical trials and prepare to initiate our first-ever international pivotal Phase 3 trial for soft tissue sarcomas with our novel cancer therapy aldoxorubicin. We reached these important inflection points in just a few years after transitioning our business focus to oncology drug development and are now significantly closer to our goal of commercializing innovative, effective treatments for people with cancer.

Cancer is a worldwide issue of epidemic proportions. There is no question of the need for new drugs that expand the choice of treatments for patients with cancer and ultimately improve lives. We have the potential to create a robust pipeline of drug candidates addressing numerous cancers. Aldoxorubicin, our dramatically improved version of the widely used chemotherapeutic agent doxorubicin, is its own pipeline, having shown to be superior to doxorubicin in an array of animal models of cancer. This is just the first drug candidate we are developing based on a novel linker technology that has the proven ability to allow attachment of multiple chemotherapeutic agents and is designed to mitigate the toxicity that limits these agents’ use.

In April 2013 we announced that we reached agreement with the U.S. Food and Drug Administration (FDA) to conduct our first Phase 3 trial with aldoxorubicin under a special protocol assessment (SPA). The international, randomized, open-label pivotal Phase 3 clinical trial will enroll approximately 400 patients with metastatic, locally advanced or unresectable soft tissue sarcomas who have either not responded to or have progressed following treatment with one or more systemic regimens of chemotherapies. The ability to conduct the clinical trial under an SPA could save significant time compared with a standard regulatory pathway.

We expect to report data from three clinical trials with aldoxorubicin this year, as follows:

We are evaluating the linker technology with a platinum-based chemotherapeutic agent in preclinical testing. Platinum agents are the most widely used chemotherapeutic drug class, and are used to treat colorectal, lung, ovarian, testicular, bladder, and head and neck cancers. We also are investigating a combination of the linker with lactosaminated albumin (LSA). This combination has shown the ability in preclinical testing to target and destroy tumors in the liver. The liver is the second most common site of metastases with 1.8 million cases reported each year worldwide.

I am proud of our team and our many achievements that have brought CytRx to this transitional time, and am highly enthusiastic about the prospects for our drugs and our future. We are firmly focused on enhancing shareholder value and creating a better and healthier world. Thank you for your continued support.

Very truly yours,

Steven A. KriegsmanPresident and Chief Executive Officer

CytRx Corporation is a biopharmaceutical research and development company specializing in oncology. The CytRx oncology pipeline is focused on the clinical development of aldoxorubicin (formerly known as INNO-206), its improved version of the widely used chemotherapeutic agent doxorubicin. CytRx has initiated an international Phase 2b clinical trial as a treatment for soft tissue sarcomas, has completed its Phase 1b/2 clinical trial primarily in the same indication, and has initiated a Phase 1b pharmacokinetics clinical trial in patients with metastatic solid tumors and a Phase 1b study of aldoxorubicin in combination with doxorubicin in patients with advanced solid tumors. The Company is initiating an international Phase 3 pivotal trial under a special protocol assessment (SPA) with aldoxorubicin as a therapy for patients with soft tissue sarcomas whose tumors have progressed following treatment with chemotherapy. CytRx is expanding its pipeline of oncology candidates based on a novel linker platform technology that can be utilized with multiple chemotherapeutic agents and could allow for greater concentration of drug at tumor sites. The Company also has rights to two additional drug candidates, tamibarotene and bafetinib. The Company completed its evaluation of bafetinib in the ENABLE Phase 2 clinical trial in high-risk B-cell chronic lymphocytic leukemia (B-CLL), and plans to seek a partner for further development of bafetinib, and is evaluating further development of tamibarotene.
