About this study

A randomized, double-blinded, multicentre phase III study to access the efficacy and safety of olaparib in combination with paclitaxel, compared with placebo in combination with paclitaxel in Asian patients with advanced gastric cancer (including gastro-oesophageal junction) who have progressed following first line therapy.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Advanced gastric cancer (including GEJ) that has progressed following first-line therapy.
  • Patients must be ≥18 years of age. Age ≥20 if Japanese
  • Provision of tumour sample (from either a resection or biopsy).
  • At least one lesion (measurable and/or non-measurable) that can be accurately assessed by imaging (CT/MRI) at baseline and following up visits.

Exclusion criteria

  • More than one prior chemotherapy regimen (except for adjuvant/neoadjuvant chemotherapy with more than 6 month wash out period) for the treatment of gastric cancer in the advanced setting.
  • Any previous treatment with a Polyadenosine 5'-diphosphoribose [poly-(ADP-ribose)] polymerisation (PARP) inhibitor, including olaparib.
  • Patients with second primary cancer, except: adequately treated non-melanoma skin cancer, curatively treated in-situ cancer of the cervix, or other solid tumours curatively treated with no evidence of disease for ≥5 years.
  • Human Epidermalgrowth Factor Receptor-2 (HER2) positive patients.

Treatment and study plan

Olaparib

Drug

Tablets-at a dose of 100mg orally twice daily, throughout each cycle (28 days); Once paclitaxel dosing is stopped, the planned monotherapy olaparib dose will be 300mg twice daily.

paclitaxel

Drug

IV infusion over 1 hour at 80 mg/m2 weekly on days 1, 8 and 15 of a 28 days schedule.

Placebo

Drug

Tablets-at a dose of 100mg orally twice daily, throughout each cycle (28 days); Once paclitaxel dosing is stopped, the planned monotherapy placebo dose will be 300mg twice daily.

Primary outcomes

  1. Overall Survival

    Time frame: Survival contact from the date of randomization and then every 8 weeks following objective disease progression and in the 7 days following OS Data Cut off (DCO); Time point(s) at which outcome measure is assessed up to 4 years

    Time from the date of randomization until death due to any cause

Secondary outcomes

  1. Progression-Free Survival (PFS)

    Time frame: Scans taken at baseline and then follow up assessments taken every 8 weeks up to Week 40 and then every 16 weeks until objective disease progression as defined by RECIST 1.1, assessed up to 3 years

    Time from randomization until the date of objective radiological disease progression according to RECIST (v1.1) or death by any cause in the absence of progression. Objective progression is defined as at least a 20% increase in the sum of the diameters of the target lesions (compared to previous minimum sum) or an overall non-target lesion assessment of progression or a new lesion.

  2. Number of Patients With Objective Response.

    Time frame: Scans taken at baseline and then follow up assessments taken every 8 weeks up to Week 40 and then every 16 weeks until objective disease progression as defined by RECIST 1.1, assessed up to 3 years

    Number of patients with objective response. Per RECIST 1.1, complete response (CR) is disappearance of all target lesions since baseline; partial response (PR) is at least a 30% decrease in the sum of the diameters of target lesions. Overall Response = CR + PR.

  3. Number of Patients Objective Response

    Time frame: Scans taken at baseline and then follow up assessments taken every 8 weeks up to Week 40 and then every 16 weeks until objective disease progression as defined by RECIST 1.1, assessed up to 3 years

    Number of patients with objective response. Per RECIST 1.1, complete response (CR) is disappearance of all target lesions since baseline; partial response (PR) is at least a 30% decrease in the sum of the diameters of target lesions. Overall Response = CR + PR.

  4. Number of Patients With Deterioration of Health Related Quality of Life (HRQoL) as Assessed by the European Organisation for Research and Treatment of Cancer (EORTC) Quality of Questionnaire Core 30 Item Module (QLQ-C30) Global HRQoL Scale

    Time frame: Pre-treatment , Day 29 and then every 4 weeks until discontinuation, assessed up to 3 years

    Number of patients with a clinically important deterioration in the global HRQoL score or death by any cause in the absence of a clincially meaningful symptom deterioration

  5. Time to Response

    Time frame: Scans taken at baseline and then follow up assessments taken every 8 weeks up to Week 40 and then every 16 weeks until objective disease progression as defined by RECIST 1.1, assessed up to 3 years

    Time from randomization to the first onset of a confirmed objective tumour response

  6. Duration of Response

    Time frame: Scans taken at baseline and then follow up assessments taken every 8 weeks up to Week 40 and then every 16 weeks until objective disease progression as defined by RECIST 1.1, assessed up to 3 years

    Time from the first documentation of CR/PR until the date of progression, or the last evaluable RECIST assessment for patients taht do not progress or progress after two or more missed visits
