The primary objective was to confirm the effect of tasquinimod in delaying disease progression or death as compared with placebo in chemo-naïve patients with metastatic castrate-resistant prostate cancer (mCRPC).
Secondary objectives included further evaluation of the safety profile of tasquinimod, comparison of clinical benefits (such as overall survival and symptoms) of tasquinimod with placebo, to evaluate the quality of life impact and to determine the pharmacokinetics of tasquinimod.
| Condition or disease | Intervention/treatment | Phase |
|---|---|---|
| Prostatic Neoplasms, Castration-Resistant | Drug: Tasquinimod Drug: Placebo | Phase 3 |
The study involved a 4-week Screening Period, Baseline Visit (Day 1) where the patient was randomised, followed by a Double Blind Treatment Period. Patients initially received tasquinimod (or corresponding placebo) at a 0.25 mg/day dose which was then titrated through 0.5 mg/day (from Day 15) to a maximum of 1 mg/day (from Day 29). If tolerability issues arose at 0.5 or 1 mg/day, patients had their dose reduced to 0.25 or 0.5 mg/day, respectively. The Double Blind Treatment Period continued until the death of the patient or any criterion for withdrawal from study treatment was reached. Any placebo treated patients with radiological disease progression confirmed by the central imaging assessment, who remained asymptomatic or mildly symptomatic were, at the Investigator's discretion, given the option to continue on active treatment (tasquinimod) during an Open-Label Treatment Period, following the same titration rule described above until progression under active treatment. All other patients stopped study treatment.
An End-of-Study Treatment/Withdrawal Visit was to be performed within 14 days after the last dose of study treatment and patients were then to be followed up every 6 months until 80% of the patients had died or 2 years after the last patient was randomised, whichever occurred last.
A PK ancillary study was to be performed in a subgroup of 12 Asian-Chinese patients before randomisation; however, due to the early termination of this study, only some samples were analysed and no PK analyses were performed.

Experimental: Tasquinimod
One capsule (0.25, 0.50 or 1 mg), taken orally once a day with water and food (preferably the main evening meal).
|
Drug: Tasquinimod
A patient initially received a 0.25 mg/day dose which was then titrated through 0.5 mg/day (from Day 15) to a maximum of 1 mg/day (from Day 29). If tolerability issues arose at 0.5 or 1 mg/day, patients had their dose reduced to 0.25 or 0.5 mg/day, respectively.
Other Name: ABR-215050 |
|
Placebo Comparator: Placebo
One capsule, taken orally once a day with water and food (preferably the main evening meal).
|
Drug: Placebo
Placebo capsules were identical to tasquinimod capsules in appearance and excipients but excluded the active compound (tasquinimod). |
- Time to Radiological Progression-Free Survival (PFS) [ Time Frame: From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 3 years ]
PFS was defined as the time from the date of randomisation to the date of radiological progression (confirmed by the central imaging assessment) or death due to any cause. Radiological progression was defined by any of the following criteria: progression of soft tissue lesions evaluated by computed tomography (CT) or magnetic resonance imaging (MRI) scan according to Response Evaluation Criteria In Solid Tumours (RECIST) version 1.1 criteria; progression of bone lesions detected with bone scan according to Prostate Cancer Clinical Trials Working Group 2 (PCWG2) criteria; or radiologically confirmed spinal cord compression or pathological fracture due to malignant progression.
The primary endpoint was centrally and independently evaluated.
- Overall Survival [ Time Frame: From randomisation up to 3 years ]An overall survival event was defined as death due to any cause. The number of participants with overall survival events is reported.
- Local Assessment of Radiological PFS [ Time Frame: From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 3 years ]The Investigator was to evaluate radiological disease progression in accordance with the criteria defined for the primary endpoint.
- Time to Symptomatic PFS Based on Local Assessment [ Time Frame: Every 3 months ]Symptomatic PFS, defined as the time from the date of randomisation to the date of appearance of pain (using pain visual analogue scale (VAS)) at a site with documented disease and analgesic use, or skeletal-related events, or death due to prostate cancer, whichever occurred first.
- Time From Randomisation to Further Treatment for Prostate Cancer [ Time Frame: Every 6 months during the follow-up period ]The need for any anti-tumour prostate cancer treatments was to be recorded during the Follow-up Period, with the time to further treatment to subsequently be derived.
- Quality of Life (QoL) [ Time Frame: Every 3 months ]
QoL measured by the Functional Assessment of Cancer Therapy Prostate Module (FACT-P) questionnaire and by the EuroQol 5-Dimension QoL Instrument (EQ-5D).
Due to the early termination of the study, a simplified data analysis (primary endpoint and overall survival) was performed to fulfil the requirement from regulatory authorities for early termination studies. Therefore, no analyses were performed on this secondary efficacy endpoint.
- Tasquinimod Pharmacokinetic (PK) Profile [ Time Frame: Up to 216 hours after a single dose and during the double blind treatment period (Day 15, 29, 57 and 127) ]
Tasquinimod PK profile:
- Following a single 1 mg dose of tasquinimod given to a subgroup of 12 Asian-Chinese patients (ancillary study).
- At steady state conditions based on limited sampling strategy.
Following termination of the study the PK analyses were not performed.
