Issued: 15 July 2019, London UK - LSE announcement
GSK announces positive headline results in Phase 3 PRIMA study of
ZEJULA (niraparib) for patients with ovarian cancer in the first
line maintenance setting
Niraparib demonstrates significant improvement in progression free
survival for women regardless of their biomarker
status
GlaxoSmithKline plc (LSE/NYSE: GSK) today announced positive
results from PRIMA (ENGOT-OV26/GOG-3012), the Phase 3 randomized,
double-blind, placebo-controlled, study of ZEJULA (niraparib) as a
maintenance therapy in patients with first-line ovarian cancer
following platinum-based chemotherapy. The study met its
primary endpoint of a statistically significant improvement in
progression free survival for women regardless of their biomarker
status.
The safety and tolerability profile of niraparib was consistent
with previous clinical trials.
Dr Hal Barron, Chief Scientific Officer and President, R&D,
GSK, said: "Almost 300,000 women around the world are diagnosed
with ovarian cancer every year, yet only about 15% of patients are
currently eligible to receive PARP inhibitors as their initial
therapy. These exciting data demonstrate that ZEJULA has the
potential to significantly benefit even more women with this
devastating cancer."
The full results from PRIMA will be presented at an upcoming
scientific meeting.
Niraparib is marketed in the United States and Europe under the
trade name ZEJULA®.
####
About PRIMA
PRIMA is a double-blind, randomized Phase 3 study designed to
evaluate niraparib versus placebo in first-line Stage III or IV
ovarian cancer patients. The study assesses the efficacy of
niraparib as maintenance treatment, as measured by progression free
survival. Platinum responsive patients were randomized 2:1 to
niraparib or placebo. The trial incorporated an individualized
niraparib starting dose of 200 mg once-daily in patients with
baseline weight <77kg or platelet count <150K/lL and 300 mg
in all other patients.
About Ovarian Cancer
Approximately 22,000 women are diagnosed each year with ovarian
cancer in the United States, and more than 65,000 women are
diagnosed annually in Europe. Ovarian cancer is the fifth most
frequent cause of cancer death among women. Despite high response
rates to platinum-based chemotherapy in the second-line advanced
treatment setting, approximately 85% of patients will experience
recurrence within two years.
About niraparib
Niraparib is an oral, once-daily PARP inhibitor that is currently
being evaluated in three pivotal trials. The ongoing development
program for niraparib includes the Phase 3 PRIMA trial, a Phase 3
trial for the treatment of patients with germline BRCA-mutated,
metastatic breast cancer (the BRAVO trial), and a registrational
Phase 2 treatment trial in patients with ovarian cancer (the QUADRA
trial). Several combination studies are also underway, including
trials of niraparib plus pembrolizumab in metastatic,
triple-negative breast cancer and advanced, platinum-resistant
ovarian cancer (the TOPACIO trial) and niraparib plus bevacizumab
in recurrent, platinum-sensitive ovarian cancer (the
ENGOT-OV24/AVANOVA trial). Janssen Biotech has licensed rights to
develop and commercialize niraparib specifically for patients with
prostate cancer worldwide, except in Japan.
Important Safety Information for ZEJULA
Myelodysplastic Syndrome/Acute Myeloid Leukaemia (MDS/AML),
including some fatal cases, was reported in 1.4% of patients
receiving ZEJULA vs 1.1% of patients receiving placebo in Trial 1
(NOVA), and 0.9% of patients treated with ZEJULA in all clinical
studies. The duration of ZEJULA treatment in patients prior to
developing MDS/AML varied from <1 month to 2 years. All patients
had received prior chemotherapy with platinum and some had also
received other DNA damaging agents and radiotherapy. Discontinue
ZEJULA if MDS/AML is confirmed.
Hematologic adverse reactions (thrombocytopenia, anaemia and
neutropenia) have been reported in patients receiving ZEJULA. Grade
≥3 thrombocytopenia, anaemia and neutropenia were reported in
29%, 25%, and 20% of patients receiving ZEJULA, respectively.
Discontinuation due to thrombocytopenia, anaemia, and neutropenia
occurred, in 3%, 1%, and 2% of patients, respectively. Do not start
ZEJULA until patients have recovered from haematological toxicity
caused by prior chemotherapy (≤ Grade 1). Monitor complete
blood counts weekly for the first month, monthly for the next 11
months of treatment, and periodically thereafter. If haematological
toxicities do not resolve within 28 days following interruption,
discontinue ZEJULA, and refer the patient to a haematologist for
further investigations.
Hypertension and hypertensive crisis have been reported in patients
receiving ZEJULA. Grade 3-4 hypertension occurred in 9% of patients
receiving ZEJULA vs 2% of patients receiving placebo in Trial 1,
with discontinuation occurring in <1% of patients. Monitor blood
pressure and heart rate monthly for the first year and periodically
thereafter during treatment with ZEJULA. Closely monitor patients
with cardiovascular disorders, especially coronary insufficiency,
cardiac arrhythmias, and hypertension. Manage hypertension with
antihypertensive medications and adjustment of the ZEJULA dose, if
necessary.
Based on its mechanism of action, ZEJULA can cause foetal harm.
Advise females of reproductive potential of the potential risk to a
foetus and to use effective contraception during treatment and for
6 months after receiving their final dose. Because of the potential
for serious adverse reactions from ZEJULA in breastfed infants,
advise lactating women to not breastfeed during treatment with
ZEJULA and for 1 month after receiving the final dose.
In clinical studies, the most common adverse reactions (Grades 1-4)
in ≥10% of patients included: thrombocytopenia (61%), anaemia
(50%), neutropenia (30%), leukopenia (17%), palpitations (10%),
nausea (74%), constipation (40%), vomiting (34%), abdominal
pain/distention (33%), mucositis/stomatitis (20%), diarrhoea (20%),
dyspepsia (18%), dry mouth (10%), fatigue/asthenia (57%), decreased
appetite (25%), urinary tract infection (13%), aspartate
aminotransferase (AST)/alanine aminotransferase (ALT) elevation
(10%), myalgia (19%), back pain (18%), arthralgia (13%), headache
(26%), dizziness (18%), dysgeusia (10%), insomnia (27%), anxiety
(11%), nasopharyngitis (23%), dyspnoea (20%), cough (16%), rash
(21%) and hypertension (20%).
Common lab abnormalities (Grades 1-4) in ≥25% of patients
included: decrease in haemoglobin (85%), decrease in platelet count
(72%), decrease in white blood cell count (66%), decrease in
absolute neutrophil count (53%), increase in AST (36%) and increase
in ALT (28%).
