Xofigo® (radium Ra 223 dichloride) Injection Recommended for Approval in the
WHIPPANY, N.J., Sept. 20, 2013
WHIPPANY, N.J., Sept. 20, 2013 /PRNewswire/ --Bayer HealthCare announced
today that the the European Committee for Medicinal Products for Human Use
(CHMP) recommended Xofigo^® (radium Ra 223 dichloride) for approval with a
proposed indication for the treatment of adults with castration-resistant
prostate cancer (CRPC), symptomatic bone metastases and no known visceral
metastases. The decision of the European Commission on the approval is
expected in the second half of 2013. Xofigo was approved by the U.S. Food and
Drug Administration in May for the treatment of patients with CRPC,
symptomatic bone metastases and no known visceral metastatic disease and is
now available in the United States at licensed facilities.^1
"We are encouraged by the positive CHMP opinion issued today, and look forward
to potentially providing radium 223 to more patients upon approval of the
European Commission," explained Kemal Malik, MD, Member of the Bayer
HealthCare Executive Committee and Head of Global Development.
About Xofigo^® (radium Ra 223 dichloride) Injection
Xofigo is indicated in the United States for the treatment of patients with
castration-resistant prostate cancer, symptomatic bone metastases and no known
visceral metastatic disease.^1
Xofigo is an alpha particle-emitting radioactive therapeutic agent with an
anti-tumor effect on bone metastases. The active ingredient in Xofigo is the
alpha particle-emitting isotope radium-223, which mimics calcium and forms
complexes with the bone mineral hydroxyapatite at areas of increased bone
turnover, such as bone metastases. The high linear energy transfer of Xofigo
may cause double-strand DNA breaks in adjacent cells, resulting in an
anti-tumor effect on bone metastases. The alpha particle range from radium-223
dichloride is less than 100 micrometers which may limit the damage to the
surrounding normal tissue.^1
In September 2009, Bayer signed an agreement with Algeta ASA (Oslo, Norway)
for the development and commercialization of Xofigo. Under the terms of the
agreement, Bayer will develop, apply for health authority approvals worldwide
and commercialize Xofigo globally. Algeta US, LLC is co-promoting Xofigo with
Bayer in the US.
Important Safety Information for Xofigo^® (radium Ra 223 dichloride) Injection
Xofigo is contraindicated in women who are or may become pregnant. Xofigo can
cause fetal harm when administered to a pregnant woman.
In the randomized trial, 2% of patients in the Xofigo arm experienced bone
marrow failure or ongoing pancytopenia, compared to no patients treated with
placebo. There were two deaths due to bone marrow failure. For 7 of 13
patients treated with Xofigo bone marrow failure was ongoing at the time of
death. Among the 13 patients who experienced bone marrow failure, 54% required
blood transfusions. Four percent (4%) of patients in the Xofigo arm and 2% in
the placebo arm permanently discontinued therapy due to bone marrow
suppression. In the randomized trial, deaths related to vascular hemorrhage in
association with myelosuppression were observed in 1% of Xofigo-treated
patients compared to 0.3% of patients treated with placebo. The incidence of
infection-related deaths (2%), serious infections (10%), and febrile
neutropenia (<1%) was similar for patients treated with Xofigo and placebo.
Myelosuppression –notably thrombocytopenia, neutropenia, pancytopenia, and
leukopenia– has been reported in patients treated with Xofigo.
Monitor patients with evidence of compromised bone marrow reserve closely and
provide supportive care measures when clinically indicated. Discontinue Xofigo
in patients who experience life-threatening complications despite supportive
care for bone marrow failure.
Monitor blood counts at baseline and prior to every dose of Xofigo. Prior to
first administering Xofigo, the absolute neutrophil count (ANC) should be
greater than or equal to 1.5 × 10^9/L, the platelet count greater than or
equal to 100 × 10^9/L, and hemoglobin greater than or equal to 10 g/dL. Prior
to subsequent administrations, the ANC should be greater than or equal to 1 ×
10^9/L and the platelet count greater than or equal to 50 × 10^9/L.
Discontinue Xofigo if hematologic values do not recover within 6 to 8 weeks
after the last administration despite receiving supportive care.
Safety and efficacy of concomitant chemotherapy with Xofigo have not been
established. Outside of a clinical trial, concomitant use of Xofigo in
patients on chemotherapy is not recommended due to the potential for additive
myelosuppression. If chemotherapy, other systemic radioisotopes, or hemibody
external radiotherapy are administered during the treatment period, Xofigo
should be discontinued.
Xofigo should be received, used, and administered only by authorized persons
in designated clinical settings. The administration of Xofigo is associated
with potential risks to other persons from radiation or contamination from
spills of bodily fluids such as urine, feces, or vomit. Therefore, radiation
protection precautions must be taken in accordance with national and local
The most common adverse reactions (greater than or equal to 10%) in the Xofigo
arm vs the placebo arm, respectively, were nausea (36% vs 35%), diarrhea (25%
vs 15%), vomiting (19% vs 14%), and peripheral edema (13% vs 10%). Grade 3 and
4 adverse events were reported in 57% of Xofigo-treated patients and 63% of
placebo-treated patients. The most common hematologic laboratory abnormalities
in the Xofigo arm (greater than or equal to 10%) vs the placebo arm,
respectively, were anemia (93% vs 88%), lymphocytopenia (72% vs 53%),
leukopenia (35% vs 10%), thrombocytopenia (31% vs 22%), and neutropenia (18%

About CRPC and Bone Metastases
Prostate cancer is the most common cancer among men in the United States
(other than skin cancer).^3 Approximately 4% of prostate cancer cases are
considered distant, which means that the cancer has spread beyond the prostate
to distant areas of the body (metastasized).^4 If prostate cancer starts to
spread to other areas of the body, it most commonly goes to the bone.^3
Bone is the most common site in the body to be affected by metastatic cancer,
and bone metastases are particularly prevalent in patients with prostate
cancer.^5 Approximately 90% of patients with metastatic prostate cancer show
evidence of bone metastases.^6,7,8,9 Bone metastases can lead to an increase
in frequency of skeletal events and are shown to be the main cause of death in
patients with CRPC.^10,11
