Study Endpoints

Primary Endpoints

Biochemical response rate (Phase II)
from date of randomization up to approximately 24 months

Biochemical response rate as defined as the percentage of participants who achieved a ≥ 50% decrease from baseline that is confirmed by a second measurement

Adverse Events (AEs) and Serious Adverse Events (SAEs), and deaths - Phase II
from day of randomization to 30 days after End of Treatment or (last AAA817 dose date + 55 days, last dose date of SoC + 30 days), whichever is later

Safety defined as the type, incidence and severity of AEs and SAEs, and deaths

Tolerability of the proposed dose of AAA817- Phase II
From on-treatment period which start from the first dose of study treatment until 30 days post-last dose date for SoC and 55 days post last-dose for AAA817

Percentage of participants who experienced Dose interruptions, reductions, discontinuation, dose intensity and duration of exposure

Radiographic progression-free survival (rPFS)- Phase III
from date of randomization up to approximately 24 months

Percentage of participants who are alive without radiographic progression or who are lost to follow-up at the time of analysis

Overall survival (OS)- Phase III
from date of randomization up to approximately 24 months

Percentage of participants who are alive or who are lost to follow-up at the time of analysis

Secondary Endpoints

Radiographic progression-free survival (rPFS)- Phase II
from date of randomization up to approximately 24 months
Progression free survival (PFS)- Phase II
from date of randomization up to approximately 24 months

Frequently asked questions about Investigators choice of SoC

What is Investigators choice of SoC used for?

Investigators choice of SoC is a small molecule being studied for the treatment of prostate cancer, specifically in adults with PSMA-positive metastatic castration-resistant prostate cancer (mCRPC) who have previously been treated with and progressed on or after [177Lu]Lu-PSMA targeted therapy. It is currently in Phase 2 clinical development.

Who makes Investigators choice of SoC?

Investigators choice of SoC is being developed by Novartis AG, a global pharmaceutical company. Novartis is listed on the stock exchange under the ticker symbol NVS. The drug is currently in Phase 2 clinical trials for the treatment of prostate cancer.

What phase is Investigators choice of SoC in?

Investigators choice of SoC is currently in Phase 2 clinical development. It is an investigational drug and has not been approved by regulatory authorities. The ongoing Phase 2 trial is actively recruiting participants to evaluate the drug in patients with previously treated PSMA-positive metastatic castration-resistant prostate cancer.

What clinical trials is Investigators choice of SoC in?

Investigators choice of SoC is being evaluated in one active Phase 2 clinical trial with the identifier NCT06780670. This open-label, randomized, active-controlled study is comparing the drug against standard of care in adults with PSMA-positive mCRPC who have progressed on or after [177Lu]Lu-PSMA targeted therapy. The trial is recruiting participants across multiple countries.

How does Investigators choice of SoC work?

Investigators choice of SoC is a small molecule, but its specific molecular target has not been disclosed in the available information. The drug is being studied as a potential treatment option for patients with PSMA-positive metastatic castration-resistant prostate cancer who have previously received [177Lu]Lu-PSMA targeted therapy.

Is Investigators choice of SoC the same as AAA817?

Investigators choice of SoC is the comparator arm in the clinical trial NCT06780670, which compares the investigational drug AAA817 against standard of care. The trial title refers to AAA817 as the study drug, while Investigators choice of SoC represents the control treatment. They are not the same intervention.
