ZEJULA offers patients proven efficacy without compromising their quality of life*1–4

Learn more about the Phase III PRIMA and PRIME studies in 1L maintenance for advanced ovarian cancer5,6

*Based on exploratory and post hoc analyses, results should be interpreted with caution.

How ZEJULA works

Poly(ADP-ribose)polymerase (PARP) is a protein that plays a role in DNA repair.7

ZEJULA is an inhibitor of PARP1 and PARP2.7

In vitro studies suggest that the cytotoxic effects of ZEJULA may involve inhibition of PARP enzymatic activity and increased formation of PARP-DNA complexes resulting in DNA damage, apoptosis, and cell death.7

Indication

ZEJULA is indicated as monotherapy for:7

  • The maintenance treatment of adult patients with advanced epithelial (FIGO Stages III and IV) high grade ovarian, fallopian tube or primary peritoneal cancer who are in response (complete or partial) following completion of first-line platinum-based chemotherapy
  • The maintenance treatment of adult patients with platinum-sensitive relapsed high grade serous epithelial ovarian, fallopian tube, or primary peritoneal cancer who are in response (complete or partial) to platinum-based chemotherapy

The only approved 1L maintenance monotherapy proven in two Phase III clinical trials: PRIMA and PRIME2,5,6

PRIMA Study design:

*PRIMA was a Phase III, randomised, double-blind, placebo-controlled, multicentre study of ZEJULA maintenance treatment in patients with advanced ovarian cancer following response on front-line platinum-based chemotherapy. Long-term investigator-assessed PFS is an ad hoc endpoint. PFS in overall population and HRd patients by BICR at 2 years were co- primary endpoints of the PRIMA study: overall population HR: 0.62 (95% Cl: 0.50, 0.76, p<0.001): HRd population HR: 0.43(95% Cl: 0.31, 0.59, p<0.001).With 3.5-year median follow-up, the most common AEs (Grades 1-4) in ≥20% of all patients in PRIMA receiving ZEJULA were: thrombocytopenia (67%), anaemia (65%), nausea (58%), neutropenia (43%), constipation (42%), fatigue (37%), headache (28%), insomnia (26%), abdominal pain (25%), vomiting (24%), arthralgia (21%), hypertension (21%), and diarrhoea (20%).1,2

ZEJULA more than doubled the 4-year PFS rates observed in HRd patients vs. placebo*†2

Reduction in risk of progression or death remained consistent with the primary analysis*†2,5

Helping protect your patients from progression in the long term2

*PFS in HRd patients and overall population by BICR were co-primary endpoints of the PRIMA study: HRd population HR: 0.43 (95% CI: 0.31, 0.59, p<0.001); overall population HR: 0.62 (95% CI: 0.50, 0.76, p<0.001).5

Long-term investigator-assessed PFS is an exploratory ad hoc endpoint, based on estimates from the 3.5-year median follow-up Kaplan-Meier curve.


Individualised starting dosing

ZEJULA is the only 1L maintenance PARPi monotherapy approved with individualised dosing from the start7,10,11

Starting dose:

200mg dosing icon

If baseline weight: <77 kg, or platelets <150,000/μl

Starting dose:

If baseline weight: ≥77 kg, and platelets ≥150,000/μl

aFollowing a protocol amendment, 35% of all patients in PRIMA (n=255/733) received an individualised starting dose.5 This is the approved dosing regimen for ZEJULA in 1L maintenance.7 Exploratory analyses, results should be interpreted with caution. Because of limited follow‐up time by primary data cut-off date among patients who received the ISD regimen, an updated data cut was taken on November 17, 2019 (6 months after the primary data cut), to perform an ad hoc analysis of PFS by IA with increased follow‐up time and event maturity. Data cut-off for the BICR analysis was May 2019.12

You may be able to maintain efficacy and reduce rates of certain Grade ≥3 side effects, with individualised dosing2,12

Supporting the efficacy of niraparib in 1L maintenance6

The PRIME study sponsored by Zai Lab (Shanghai) Co. was conducted in China, using independently manufactured niraparib capsules. The Zai Lab niraparib capsule has the same formulation composition as GSK’s ZEJULA capsule, with limited in vitro bioequivalence data available.6,8,9 Care should be taken when interpreting results due to possible differences between products, patient populations and standard of care. Cross-trial comparisons cannot be made.
At the time of study initiation, no commercial HRD assay was approved in China; the laboratory-developed, unvalidated BGI HRD assay was used in PRIME, with an HRD scoring system set by BGI prospectively.6,8

With ZEJULA, an established safety profile means you know what they may experience2,5

aIncludes two additional patients who received ZEJULA and experienced a TEAE leading to a dose interruption and subsequently discontinued treatment; also includes one patient in the placebo group who experienced the adverse event ascites at the time of disease progression and was recorded as discontinuing treatment because of disease progression.

In PRIMA, no new safety signals were reported at 3.5-year median follow-up2

Niraparib treatment in PRIME had a low TEAE-related discontinuation rate of <7%†6

  • The most common all- and Grade ≥3 TEAEs were haematological and gastrointestinal16
  • 6.7% TEAE-related discontinuation rate with niraparib, similar to placebo (5.4%)6
  • In the niraparib arm, TEAE-related interruptions or dose reductions affected 62.7% and 40.4% of niraparib patients, and 19.4% and 6.2% of placebo patients, respectively6,16

In PRIME, all patients received individualised dosing prospectively6

The PRIME study sponsored by Zai Lab (Shanghai) Co. was conducted in China, using independently manufactured niraparib capsules. The Zai Lab niraparib capsule has the same formulation composition as GSK’s ZEJULA capsule, with limited in vitro bioequivalence data available.6,8,9 Care should be taken when interpreting results due to possible differences between products, patient populations and standard of care. Cross-trial comparisons cannot be made.

Improved tolerability was observed with tailored dosing from the start in 1L maintenance2,7,12

ZEJULA offers your patients the confidence of a proven long-term safety profile2

The tolerability of niraparib has been established in multiple clinical studies2,5,6,13–15

Individualised starting dosing may help you get ahead of certain side effects12

aMDS/AML incidence rate was the same for both ZEJULA- and placebo-treated patients (1.2%). The majority of patients who experienced MDS/AML events had undergone additional chemotherapy and/or PARPi therapy.2

Tailoring dosing from the start may reduce their risk of certain AEs2,12

In patients receiving an individualised vs. fixed starting dose:

  • All common TEAEs (≥20%) were less frequently reported2
  • The rates of certain Grade ≥3 haematological AEs were reduced, including thrombocytopenia, anaemia and neutropenia2,12
