Oncoinvent Sees Promise with Radspherin® for Colorectal Cancer

Oncoinvent Reports Positive Outcomes from Radspherin® Trial

Recent clinical data highlights the effectiveness of Oncoinvent’s innovative radiopharmaceutical therapy, Radspherin®, in managing colorectal peritoneal metastases. This therapy represents a significant advancement in cancer treatment, particularly for patients battling the challenges posed by peritoneal disease. The insights from the recent Phase 1/2a trial have ignited hope within the medical community regarding future treatment options.

The Crucial Role of Radspherin® in Colorectal Cancer

In the ongoing struggle against colorectal cancer, managing peritoneal metastases is notably challenging. These metastases correlate with a grim prognosis and lower survival rates compared with other forms of cancer recurrence. As a result, patients often face distressing symptoms and multiple hospital visits. Standard treatment options, including surgery to remove tumors, frequently fall short since microscopic cancer cells often remain, leading to recurrence.

Oncoinvent's Radspherin® stands out as a potential game changer. This treatment involves direct intraperitoneal delivery of radium-224, designed to specifically target and eliminate residual microscopic cancer cells post-surgery. The clinical trial demonstrated substantial promise in enhancing a patient's chance of remaining free from recurrence.

Trial Findings and Implications

In the Phase 1/2a study, which involved 47 participants, Radspherin® was assessed using a 7 MBq dose. The primary focus was to determine peritoneal recurrence-free survival (pRFS). Notably, only 27.8% of the participants experienced recurrence at 18 months, in stark contrast to the approximately 50% rate expected with standard care. Additionally, while 61.1% of patients had any recurrence, just 22.7% had peritoneal disease as the initial site of recurrence.

Clinician Insights

Dr. Stein Gunnar Larsen, Principal Investigator at Oslo University Hospital, expressed optimism about Radspherin®'s potential, stating that the outcomes achieved in this challenging patient group exceed expectations. He envisions a future where Radspherin® is a viable treatment option for patients facing similar challenges.

Expert Commentary

Prof. Dr. Wilhelm Graf, another Principal Investigator, reiterated the substantial therapeutic difficulties presented by colorectal peritoneal metastases. He emphasized that these trial results signify significant hope for developing effective treatment avenues.

CEO Oystein Soug shared the team's motivation, believing deeply in the potential of Radspherin® to address these pressing medical challenges. He gratefully acknowledged the contributions of patients and clinical teams that facilitated the trial.

Current Developments and Future Directions

At present, Radspherin® is undergoing evaluation in an ongoing Phase 2 trial aimed at treating peritoneal carcinomatosis stemming from ovarian cancer. The initial safety reviews have been promising, and patient recruitment continues as planned across multiple locations in Europe and the US.
