Kairos Pharma Ltd. (NYSE American: KAPA) has entered into a strategic collaboration with Bayer to evaluate its lead antibody candidate, ENV-105 (carotuximab), in combination with Bayer's XOFIGO (radium-223 dichloride) for the treatment of metastatic castration-resistant prostate cancer involving bone. ENV-105 is a first-in-class CD105/BMP signaling inhibitor designed to overcome cancer drug resistance and is currently being evaluated in Phase 1 and Phase 2 clinical trials. The company previously reported interim Phase 2 data showing median progression-free survival of more than 13 months in prostate cancer patients, while XOFIGO is the only FDA-approved alpha-emitting radiopharmaceutical for symptomatic bone metastases in this patient population.
The collaboration will evaluate whether ENV-105 can enhance and extend responses to XOFIGO by targeting CD105, a protein associated with treatment resistance following androgen receptor inhibition and radiation therapy. Kairos said preclinical studies have demonstrated ENV-105's ability to re-sensitize tumors to radiation, and management believes combining the therapy with XOFIGO could provide a more durable treatment option for patients with advanced prostate cancer. This partnership underscores the potential of combining targeted immunotherapy with radiopharmaceuticals to tackle resistant cancers.
Based in Los Angeles, California, Kairos Pharma Ltd. is at the forefront of oncology therapeutics, utilizing structural biology to overcome drug resistance and immune suppression in cancer. The company's lead candidate, ENV-105, targets CD105, a protein identified as a key driver of resistance and disease relapse in response to standard therapy. ENV-105 aims to reverse drug resistance and restore the effectiveness of standard therapies across multiple cancer types. Currently, ENV-105 is in a Phase 2 clinical trial for castrate-resistant prostate cancer and a Phase 1 trial for non-small cell lung cancer aimed at addressing significant unmet medical needs.
This collaboration is significant because it addresses a major challenge in oncology: treatment resistance. By combining ENV-105 with XOFIGO, the companies hope to improve outcomes for patients with advanced prostate cancer who have limited options. The news is particularly important for investors and stakeholders monitoring developments in cancer therapeutics, as positive results could lead to a new standard of care.
