Newly published poster on the single-arm 27-patient safety and dosimetry lead-in provides key updates including:
A median rPFS time of 11.5 months
A best radiographic objective response (CR, PR) was achieved in 60% of the 10 participants with evaluable disease at baseline
PNT2002 was well tolerated with no treatment-related deaths
INDIANAPOLIS, Sept. 10, 2022 (GLOBE NEWSWIRE) — POINT Biopharma Global Inc. (NASDAQ: PNT) (the “Company” or “POINT”), a company accelerating the discovery, development and global access to life-changing radiopharmaceuticals, today published a poster at ESMO Congress 2022 containing updated efficacy and safety data from the 27-patient safety and dosimetry lead-in cohort for the Company’s phase 3 SPLASH trial (NCT04647526) evaluating PNT2002 for the treatment of metastatic castration-resistant prostate cancer (mCRPC). Key findings include a median rPFS time of 11.5 months, along with a well-tolerated safety profile with no treatment-related deaths and few treatment-related AEs of grade 3 or higher.
“rPFS is the primary endpoint of the SPLASH trial, making these positive signals from the lead-in cohort extremely promising,” said Dr. Neil Fleshner, Chief Medical Officer of POINT Biopharma. “I believe the dosing schedule of four cycles of 177Lu-PNT2002 at 6.8 GBq per cycle every 8 weeks is a unique differentiator offering lower overall whole-body radiation and shorter overall treatment than currently approved PSMA RLT therapies.”
The full poster is available to download at the Company’s investor relations website, located at https://www.pointbiopharma.com/investors#investor-presentations. Upcoming third-party coverage of the data will include video interviews of Dr. Fleshner by UroToday, and of Dr. Aaron R. Hansen by VuMedi. Dr. Hansen is Deputy Director for the Division of Cancer Services at Metro South Health, a Medical Oncologist at Princess Alexandra Hospital, and an Associate Professor of Medicine at the University of Toronto and the University of Queensland.
The phase 3 SPLASH trial is a multi-center, randomized, open label assessment of PNT2002 in participants with prostate-specific membrane antigen (PSMA)-expressing mCRPC who have progressed on androgen receptor pathway inhibitor (ARPI) therapy. Compared to other currently approved radioligand therapies for prostate cancer, SPLASH is evaluating PNT2002 earlier in the treatment pathway and using fewer and lower doses. The treatment regimen for the lead-in cohort is the same as the regimen being investigated in the randomization part of the trial: participants receive up to four cycles of 177Lu-PNT2002 at 6.8 GBq per cycle every 8 weeks. The SPLASH trial is currently enrolling patients across 53 sites in North America, Europe, and UK, and site activations remain ongoing to expedite accrual.
The poster is titled “Efficacy and Safety of 177Lu-PNT2002 prostate-specific membrane antigen (PSMA) Therapy in Metastatic Castration Resistant Prostate Cancer (mCRPC): Initial Results from SPLASH” (e-Poster #1400P). The poster’s newly released data were based on a median follow-up of 11.7 months, updating the previously published abstract which was based on a median follow-up of 7.6 months. Key findings for the lead-in cohort include:
“In this patient population, which was not as heavily pre-treated as the population studied in the published randomized trials of 177Lu-PSMA-617, PNT2002 was very well tolerated,” said Scott Tagawa, MD, MS, FACP, Medical Oncologist at Weill Cornell Medicine, Professor of Medicine at Meyer Cancer Center, SPLASH trial investigator, and senior author on the SPLASH poster at ESMO. “The early efficacy signals of PSA and measurable disease responses, combined with the favorable, though non-randomized, rPFS data, are encouraging for success of the phase 3 study.”
Prior to the publication of the lead-in cohort data, the Company hosted a 45-minute educational webinar on August 18, 2022 entitled “Understanding the PNT2002 SPLASH Trial Control Arm” featuring presentations from Dr. Oliver Sartor and Dr. Kim Chi.
Both the poster and the webinar are available under the Presentations tab of the Investors section of the Company’s website, located at https://www.pointbiopharma.com/investors#investor-presentations.

About the SPLASH Trial
The phase 3 SPLASH trial is a multi-center, randomized, open label assessment of PNT2002 in participants with PSMA-expressing mCRPC who have progressed on androgen receptor pathway inhibitor (ARPI) therapy and refuse, or are not eligible for, chemotherapy. The randomization phase of the study is expected to enroll approximately 400 participants across North America, Europe, and the United Kingdom. Participants will be randomized 2:1 with participants in arm A receiving PNT2002 and participants in arm B receiving either abiraterone or enzalutamide. Participants in arm B who experience centrally assessed radiographic progression and meet protocol eligibility will have the option to crossover and receive PNT2002. Patients will be subject to follow-up for up to 5 years from their first PNT2002 dose. The primary endpoint of the study is radiographic progression-free survival. Key secondary endpoints include overall response rate, overall survival, and pharmacokinetics.
