Highlights
A complete response, based on Response Evaluation Criteria In Solid Tumours (RECIST v1.1) assessment, has been reported from the first patient with metastatic castrate-resistant prostate cancer (mCRPC) to ever receive two cycles of Clarity’s 67Cu-SAR-bisPSMA at the 8GBq dose level.
The patient remains with undetectable levels of Prostate Specific Antigen (PSA) for almost 6 months, following the administration of the second dose of 67Cu-SAR-bisPSMA. PSA is a marker used to assess clinical response to treatment and an indicator of the recurrence of prostate cancer.
The patient had no detectable lesions using positron emission tomography (PET) imaging with 64Cu-SAR-bisPSMA following the treatment.
The first cycle of 67Cu-SAR-bisPSMA was administered under the SECuRE trial protocol, and the second cycle under the US Food and Drug Administration’s (FDA) Expanded Access Program (EAP).
The participant was heavily pre-treated having failed multiple lines of therapy, including androgen deprivation therapy (ADT), androgen receptor pathway inhibitors (ARPIs), chemotherapy and a poly (ADP-ribose) polymerase (PARP) inhibitor.
No adverse events related to 64Cu-SAR-bisPSMA were observed. The safety profile of 67Cu-SAR-bisPSMA was favourable, with all adverse events related to the product showing improvement or resolution over time.
No dose limiting toxicities (DLTs) have been reported in any of the patients treated in the SECuRE trial to date. The recruitment is ongoing for cohort 4, the first multi-dose cohort, at the highest dose level of 12GBq.
Just got press release so sharing for Australian users. If you are in Australia, It can be your next treatment.
