General information about the trial
|
|||
Main objective of the trial |
The main purpose of this study was to evaluate the efficacy, safety, and pharmacokinetics (PK) of ipatasertib plus abiraterone and prednisone/prednisolone compared with placebo plus abiraterone and prednisone/prednisolone in participants with metastatic castrate-resistant prostate cancer (mCRPC).
|
||
Protection of trial subjects |
All study participants were required to read and sign an Informed Consent Form (ICF).
|
||
Background therapy |
All participants who did not undergo orchiectomy were on Gonadotropin-releasing hormone (GnRH) agonists or antagonists. All participants on the study were on prednisone/prednisolone 5mg BID concomitantly with the study medication. | ||

Screening details |
Participants were randomized in 1:1 ratio to below treatment arms: abiraterone+prednisone/prednisolone+ipatasertib(Ipat+Abi) & abiraterone+prednisone/prednisolone+placebo(Pbo+Abi). 3 participants in Pbo & 1 in Ipat didn't receive any treatment. 5 participants randomized to Pbo took at least 1 dose of ipat & included in Ipat for safety analysis. | ||||||||||||||||||||||||||||||

Time to pain progression was defined as the time from randomization to the first occurrence of confirmed clinically meaningful cancer-related pain progression event. Cancer-related pain progression refers to pain onset for participants who were asymptomatic at baseline or pain worsening for those who were mildly symptomatic at baseline. Pain severity was graded on a 10-point numeric rating scale [NRS], with 0=no pain and 10=severe pain. Pain severity progression was defined as a ≥ 2-point absolute increase from baseline. KM estimates were used to determine the median time to pain progression.

Time to function deterioration=time from date of randomization to date of 10-point or more score decrease on either EORTC QLQ-C30 5-item PF/2-item RF scale scores, held for two consecutive assessments or death within 28 days, whichever occurs first. EORTC QLQ-C30 consists of 30 questions that assess 5 aspects of participant functioning (physical,emotional,role,cognitive & social), 3 symptom scales (fatigue,nausea,vomiting&pain), GHS/QoL & 6 single items (dyspnea,insomnia,appetite loss,constipation,diarrhea & financial difficulties). PF scale has 5 questions about participants' physical functioning & daily activities. RF scale has 2 questions about work/daily activities & hobbies/leisurely activities. PF&RF are scored on a 4-point scale (1=Not at All to 4=Very Much). Obtained scores are linearly transformed to score range of 0-100, where higher scores=higher response level (better PF) & better functioning/support. ITT population.

ORR=percentage of participants who had an objective response (OR) with measurable disease at baseline. OR=complete response (CR) or partial response (PR) on 2 consecutive occasions ≥4 weeks apart, as determined by investigator using RECIST v1.1 and PCWG3 criteria in participants with measurable disease at baseline. CR was defined as disappearance of all target lesions & any pathological lymph nodes (whether target or non-target) must have a reduction in short axis to < 10 mm. PR was defined as at least a 30% decrease in the SOD of target lesions, taking as reference the baseline SOD. An estimate of ORR was calculated for each treatment arm, and its 95% CI was calculated using the Clopper-pearson method. PTEN loss population included all randomized participants with PTEN loss tumors by IHC, regardless of whether or not the participant received the assigned treatment.

Percentage of Participants with Adverse Events (AEs) | ||||||||||||

An AE was any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An AE can therefore be any unfavorable and unintended sign (including abnormal laboratory values or abnormal clinical test results), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study were also considered as AEs. SE population included all participants who received any amount of the study treatment. 5 participants randomized to the placebo arm took at least one dose of ipatasertib and hence were included in the Ipat + Abi arm for safety analysis. Percentages have been rounded off.
