10 abstracts including AG as an investigational
foundation in first-line metastatic pancreatic cancer research
being presented during the meeting
Celgene Corporation (NASDAQ:CELG) today announced that 10
studies highlighting combinations that include a foundation of
ABRAXANE® (paclitaxel protein-bound particles for injectable
suspension)(albumin-bound) and gemcitabine are being presented
during the 2016 ASCO Gastrointestinal Cancers Symposium (ASCO GI),
establishing the therapy as the foundation for research in
first-line metastatic pancreatic cancer.
“ABRAXANE is the only chemotherapy approved in combination with
gemcitabine based on an improvement in overall survival for first
line metastatic pancreatic cancer patients and is fast becoming the
standard of care in this extremely difficult to treat disease,”
said Jacqualyn A. Fouse, Ph.D., President, Hematology/Oncology for
Celgene. “We are excited that ABRAXANE plus gemcitabine is serving
as the foundation for a new wave of potential treatments that may
further improve the treatment paradigm in this disease and are
fully committed to continuing to serve these patients.”

Important Safety Information
WARNING -
NEUTROPENIA
- Do not administer ABRAXANE therapy
to patients who have baseline neutrophil counts of less than 1500
cells/mm3. In order to monitor the occurrence of bone
marrow suppression, primarily neutropenia, which may be severe and
result in infection, it is recommended that frequent peripheral
blood cell counts be performed on all patients receiving
ABRAXANE
- Note: An albumin form of paclitaxel
may substantially affect a drug’s functional properties relative to
those of drug in solution. DO NOT SUBSTITUTE FOR OR WITH OTHER
PACLITAXEL FORMULATIONS
CONTRAINDICATIONS
Neutrophil Counts
- ABRAXANE should not be used in patients
who have baseline neutrophil counts of <1500 cells/mm3
Hypersensitivity
- Patients who experience a severe
hypersensitivity reaction to ABRAXANE should not be rechallenged
with the drug
WARNINGS AND PRECAUTIONS
Hematologic Effects
- Bone marrow suppression (primarily
neutropenia) is dose-dependent and a dose-limiting toxicity of
ABRAXANE. In a clinical study, Grade 3-4 neutropenia occurred in
38% of patients with pancreatic cancer
- Monitor for myelotoxicity by performing
complete blood cell counts frequently, including prior to dosing on
Days 1, 8, and 15 for pancreatic cancer
- Do not administer ABRAXANE to patients
with baseline absolute neutrophil counts (ANC) of less than
1500 cells/mm3
- In patients with adenocarcinoma of the
pancreas, withhold ABRAXANE and gemcitabine if the ANC is less than
500 cells/mm3 or platelets are less than 50,000 cells/mm3 and
delay initiation of the next cycle if the ANC is less than 1500
cells/mm3 or platelet count is less than 100,000 cells/mm3 on
Day 1 of the cycle. Resume treatment with appropriate dose
reduction if recommended
Nervous System
- Sensory neuropathy is dose- and
schedule-dependent
- The occurrence of Grade 1 or 2 sensory
neuropathy does not generally require dose modification
- If ≥ Grade 3 sensory neuropathy
develops, withhold ABRAXANE treatment until resolution to
≤ Grade 1 followed by a dose reduction for all subsequent
courses of ABRAXANE
Sepsis
- Sepsis occurred in 5% of patients with
or without neutropenia who received ABRAXANE in combination with
gemcitabine
- Biliary obstruction or presence of
biliary stent were risk factors for severe or fatal sepsis
- If a patient becomes febrile
(regardless of ANC), initiate treatment with broad-spectrum
antibiotics
- For febrile neutropenia, interrupt
ABRAXANE and gemcitabine until fever resolves and ANC
≥1500 cells/mm3, then resume treatment at reduced dose
levels
Pneumonitis
- Pneumonitis, including some cases that
were fatal, occurred in 4% of patients receiving ABRAXANE in
combination with gemcitabine
- Monitor patients for signs and symptoms
and interrupt ABRAXANE and gemcitabine during evaluation of
suspected pneumonitis
- Permanently discontinue treatment with
ABRAXANE and gemcitabine upon making a diagnosis of
pneumonitis
Hypersensitivity
- Severe and sometimes fatal
hypersensitivity reactions, including anaphylactic reactions, have
been reported
- Patients who experience a severe
hypersensitivity reaction to ABRAXANE should not be rechallenged
with this drug
Hepatic Impairment
- Because the exposure and toxicity of
paclitaxel can be increased with hepatic impairment, administration
of ABRAXANE in patients with hepatic impairment should be performed
with caution
- Patients with hepatic impairment may be
at an increased risk of toxicity, particularly from
myelosuppression, and should be monitored for development of
profound myelosuppression
- For pancreatic adenocarcinoma, ABRAXANE
is not recommended for patients with moderate to severe hepatic
impairment (total bilirubin >1.5 x ULN and AST ≤10 x ULN)
Albumin (Human)
- ABRAXANE contains albumin (human), a
derivative of human blood
Use in Pregnancy: Pregnancy Category D
- ABRAXANE can cause fetal harm when
administered to a pregnant woman
- If this drug is used during pregnancy,
or if the patient becomes pregnant while receiving this drug, the
patient should be apprised of the potential hazard to the
fetus
- Women of childbearing potential should
be advised to avoid becoming pregnant while receiving ABRAXANE
Use in Men
- Men should be advised not to father a
child while receiving ABRAXANE
ADVERSE REACTIONS
- Among the most common (≥20%) adverse
reactions in the phase III study, those with a ≥5% higher incidence
in the ABRAXANE/gemcitabine group compared with the gemcitabine
group are neutropenia (73%, 58%), fatigue (59%, 46%), peripheral
neuropathy (54%, 13%), nausea (54%, 48%), alopecia (50%, 5%),
peripheral edema (46%, 30%), diarrhea (44%, 24%), pyrexia (41%,
28%), vomiting (36%, 28%), decreased appetite (36%, 26%), rash
(30%, 11%), and dehydration (21%, 11%)
- Of these most common adverse reactions,
those with a ≥2% higher incidence of Grade 3-4 toxicity in the
ABRAXANE/gemcitabine group compared with the gemcitabine group,
respectively, are neutropenia (38%, 27%), fatigue (18%, 9%),
peripheral neuropathy (17%, 1%), nausea (6%, 3%), diarrhea (6%,
1%), pyrexia (3%, 1%), vomiting (6%, 4%), decreased appetite
(5%, 2%), and dehydration (7%, 2%)
- Thrombocytopenia (all grades) was
reported in 74% of patients in the ABRAXANE/gemcitabine group vs
70% of patients in the gemcitabine group
- The most common serious adverse
reactions of ABRAXANE (with a ≥1% higher incidence) are pyrexia
(6%), dehydration (5%), pneumonia (4%), and vomiting (4%)
- The most common adverse reactions
resulting in permanent discontinuation of ABRAXANE were peripheral
neuropathy (8%), fatigue (4%), and thrombocytopenia (2%)
- The most common adverse reactions
resulting in dose reduction of ABRAXANE are neutropenia (10%) and
peripheral neuropathy (6%)
- The most common adverse reactions
leading to withholding or delay in ABRAXANE dosing are neutropenia
(16%), thrombocytopenia (12%), fatigue (8%), peripheral neuropathy
(15%), anemia (5%), and diarrhea (5%)
- Other selected adverse reactions with a
≥5% higher incidence for all-grade toxicity in the
ABRAXANE/gemcitabine group compared to the gemcitabine group,
respectively, are asthenia (19%, 13%), mucositis (10%, 4%),
dysgeusia (16%, 8%), headache (14%, 9%), hypokalemia (12%, 7%),
cough (17%, 7%), epistaxis (15%, 3%), urinary tract infection
(11%, 5%), pain in extremity (11%, 6%), arthralgia (11%, 3%),
myalgia (10%, 4%), and depression (12%, 6%)
- Other selected adverse reactions with a
≥2% higher incidence for Grade 3-4 toxicity in the
ABRAXANE/gemcitabine group compared to the gemcitabine group are
thrombocytopenia (13%, 9%), asthenia (7%, 4%), and hypokalemia (4%,
1%)
Postmarketing Experience With ABRAXANE and Other Paclitaxel
Formulations
- Severe and sometimes fatal
hypersensitivity reactions have been reported with ABRAXANE. The
use of ABRAXANE in patients previously exhibiting hypersensitivity
to paclitaxel injection or human albumin has not been studied
- There have been reports of congestive
heart failure, left ventricular dysfunction, and atrioventricular
block with ABRAXANE, primarily among individuals with underlying
cardiac history or prior exposure to cardiotoxic drugs
- There have been reports of
extravasation of ABRAXANE. Given the possibility of extravasation,
it is advisable to monitor closely the ABRAXANE infusion site for
possible infiltration during drug administration
DRUG INTERACTIONS
- Caution should be exercised when
administering ABRAXANE concomitantly with medicines known to
inhibit or induce either CYP2C8 or CYP3A4
USE IN SPECIFIC POPULATIONS
Nursing Mothers
- It is not known whether paclitaxel is
excreted in human milk. Because many drugs are excreted in human
milk and because of the potential for serious adverse reactions in
nursing infants, a decision should be made to discontinue nursing
or to discontinue the drug, taking into account the importance of
the drug to the mother
Pediatric
- The safety and effectiveness of
ABRAXANE in pediatric patients have not been evaluated
Geriatric
- Diarrhea, decreased appetite,
dehydration, and epistaxis were more frequent in patients
65 years or older compared with patients younger than 65 years
old who received ABRAXANE and gemcitabine in adenocarcinoma of the
pancreas
Renal Impairment
- There are insufficient data to permit
dosage recommendations in patients with severe renal impairment or
end stage renal disease (estimated creatinine clearance <30
mL/min)
DOSAGE AND ADMINISTRATION
- Do not administer ABRAXANE to patients
with metastatic adenocarcinoma of the pancreas who have moderate to
severe hepatic impairment
- Do not administer ABRAXANE to any
patient with total bilirubin greater than 5 x ULN or AST greater
than 10 x ULN
- Dose reductions or discontinuation may
be needed based on severe hematologic, neurologic, cutaneous, or
gastrointestinal toxicity
- Monitor patients closely
