Intensity Therapeutics and SAKK Present Significant Advances in Breast Cancer Trials at SABCS 2024

Significant Progress in Breast Cancer Research

At the 2024 San Antonio Breast Cancer Symposium (SABCS), Intensity Therapeutics, Inc. and The Swiss Group for Clinical Cancer Research (SAKK) shared groundbreaking updates about their clinical trials aimed at treating breast cancer.

Overview of the Study Presentations

The symposium highlighted the final data from the completed INVINCIBLE-2 study and the ongoing INVINCIBLE-4 trial, underlining the innovative approach towards treatment for Triple Negative Breast Cancer (TNBC). Dr. Andreas Mueller, a leading investigator at SAKK and Head of the Breast Center at Kantonsspital Winterthur, presented these findings to an audience of cancer researchers and healthcare professionals on December 11.

The INVINCIBLE-2 Study

The INVINCIBLE-2 study primarily focused on utilizing INT230-6, Intensity's proprietary therapy, to evaluate its efficacy in killing tumors directly and boosting the immune system's response against cancer. Results indicated that patients receiving INT230-6 showed over 95% tumor killing in certain cases, with significant necrosis observed in 74% of subjects who presented with tumors larger than two centimeters during surgical evaluations. Analysis of gene expression indicated a notable difference between pre-treatment and surgical samples, emphasizing the potential of INT230-6 to activate immune responses through T-cell and B-cell signaling.

This trial lay the groundwork for understanding how local treatment can invoke systemic immune engagement while maintaining a favorable safety profile.

Insights on INVINCIBLE-4 Study

The INVINCIBLE-4 trial, still ongoing, aims to compare the clinical activity of INT230-6 combined with standard neoadjuvant immunochemotherapy versus the standard treatment alone. With the primary goal of achieving a pathological complete response (pCR), enrollment continues with a target of 54 patients. Dr. Mueller expressed hopes that if INT230-6 can significantly improve pCR rates without added toxicity, this could redefine neoadjuvant treatment protocols for patients with aggressive TNBC.

The need for safer alternatives in cancer treatment is pressing, particularly for high-risk populations encountering harsh side effects from conventional therapies. Thus, the outcomes of these studies could have profound implications not just for breast cancer, but potential applications to other cancer types as well.

Looking Ahead

As enrollment progresses, the clinical and regulatory community eagerly observes the advancements emerging from these pivotal clinical trials. Besides its immediate implications for TNBC, the methodologies refined through both trials could enhance strategies against varied cancers in the near future. Intensity Therapeutics’ innovative use of intratumoral injection seeks to push the envelope in cancer treatment, presenting a significant shift in handling malignancies traditionally resistant to both chemotherapy and immunotherapies.

Conclusion

The interdisciplinary collaboration between Intensity Therapeutics and SAKK represents a crucial step towards advancing personalized medicine for breast cancer patients. The results presented at SABCS 2024 emphasize not only the hope inherent in novel therapeutic strategies but also the ongoing commitment of researchers to improve patient outcomes in the battle against cancer.
