HENDERSON, Nev. -- January 28, 2013

Spectrum Pharmaceuticals (NasdaqGS: SPPI), a biotechnology company with fully
integrated commercial and drug development operations with a primary focus in
hematology and oncology, today announced safety findings from the pivotal,
registrational Phase 2 BELIEF trial of belinostat, a pan-histone deacetylase
(HDAC) inhibitor. As featured in an oral presentation at the T-Cell Lymphoma
Forum held in San Francisco, January 24-26, the BELIEF trial safety evaluation
showed belinostat had an acceptable safety profile in patients with
relapsed/refractory peripheral T-cell lymphoma (R/R PTCL), including patients
who have received a previous allogeneic or autologous stem cell transplant.

The BELIEF trial is evaluating the efficacy and safety of intravenous
belinostat for the treatment of patients with R/R PTCL. As announced in
December 2012, the BELIEF trial surpassed an objective response rate (ORR) of
at least 20% in these patients, the study’s primary efficacy endpoint as
established under a Special Protocol Assessment (SPA) agreement with the U.S.
Food and Drug Administration (FDA).

“We are pleased that the T-Cell Lymphoma Forum, one of the preeminent
conferences for innovation in the treatment of blood cancers, highlighted the
BELIEF study comprehensive safety profile,” stated Rajesh C. Shrotriya, M.D.,
Chairman, President and Chief Executive Officer of Spectrum Pharmaceuticals,
Inc. “Belinostat showed acceptable safety findings in the BELIEF trial which
was designed to enroll relapsed or refractory PTCL patients; including those
who received a previous stem cell transplant; with a platelet count greater
than or equal to 50,000. Many of these refractory patients with low platelet
counts were not eligible for treatment on trials with alternative agents. The
BELIEF safety profile, as well as ongoing studies of belinostat in combination
with cytotoxic regimens, may provide support to seek approval for indications
in both monotherapy and combination therapy with belinostat for patients with
PTCL. We look forward to progress of the program, including an anticipated NDA
filing by mid-2013.”

About Peripheral T-Cell Lymphoma

According to the Lymphoma Research Foundation (www.lymphoma.org), lymphoma is
the most common blood cancer. The two main forms of lymphoma are Hodgkin's
lymphoma and non-Hodgkin's lymphoma (NHL). Lymphoma occurs when lymphocytes, a
type of white blood cell, grow abnormally where they typically reside in the
lymph glands. The body has two main types of lymphocytes that can develop into
lymphomas: B-lymphocytes (B-cells) and T-lymphocytes (T-cells). Peripheral
T-cell lymphoma (PTCL) comprises a group of rare and aggressive NHLs that
develop from mature T-cells. PTCL accounts for approximately 10 to 15% of all
NHL cases in the United States, and projections for annual cancer incidences
point to 15,500 new cases of PTCL in the U.S.

About Belinostat and the BELIEF Trial

Belinostat is a Class I and II HDAC inhibitor being studied in multiple
clinical trials as a single agent or in combination with chemotherapeutic
agents for the treatment of various hematological and solid cancers. Its
anticancer effect is thought to be mediated through multiple mechanisms of
action, including the inhibition of cell proliferation, induction of apoptosis
(programmed cell death), inhibition of angiogenesis, induction of
differentiation, and the resensitization of cells that have become resistant
to anticancer agents such as platinums, taxanes and topoisomerase II
inhibitors. Belinostat is the only HDAC inhibitor in clinical development with
multiple potential routes of administration, including short and continuous
intravenous infusion; and oral administration.

Conducted under a Special Protocol Assessment (SPA) agreement with the FDA,
the pivotal, registrational Phase 2 BELIEF trial is evaluating intravenous
belinostat as monotherapy for relapsed or refractory peripheral T-cell
lymphoma (PTCL), an indication for which this drug candidate has been granted
Orphan Drug and Fast Track designations by the FDA. The BELIEF trial is an
open-label, international, single arm efficacy and safety study in patients
with relapsed or refractory PTCL, who have failed at least one prior systemic
therapy. The primary endpoint of the trial is centrally reviewed objective
response rate (ORR). The trial included approximately 100 clinical centers
globally, with completion of patient enrollment announced in September 2011.
