MacroGenics finished enrolling parties for the TAMARAK Phase 2 survey of vobra duo in November 2023. This survey involves patients with metastatic castration-resistant prostate cancer who has previously received 1 treatment targeting the androgen receptor pathway. These participants might besides have had 1 prior treatment, including taxane, but no another chemotherapy. The survey Aims is simply a test of 2 different doses of vobra duo, either 2.0 mg/kg or 2.7 mg/kg, given all 4 weeks.

‘The interim safety and anti-tumor activity observed to date in the TAMARAK survey looks very promising for patients with metastatic castration-resistant prostate cancer,’ Johann DeBono, Regius prof. of Cancer investigation and prof. in Experimental Cancer medicine at The Institute of Cancer Research, London and The Royal Marsden NHS Foundation Trust, established in a release.

DeBono continued, "With the limited treatment options presently available to these patients, this fresh ADC molecule could possibly become the first therapy targeting B7-H3 in patients with prostate cancer and would present an crucial fresh treatment for this population."

Further in the release, MacroGenics revealed 5 deaths in the study. They said 2 deaths have been introduced unrelated to the study, while the another 3 are being invested.

In addition, a patient in the 2.7 mg/kg dosing cohort had a Grade 3 plenary effect that is recorded as having a fatal outcome.
