"We have initiated expanded clinical trials designed for potential approval of our proprietary PD-1 and CTLA-4 antibodies in second line cervical cancer," said Garo Armen, Ph.D., Chairman and CEO of Agenus. "We are pursuing both monotherapy and combination trials as a dual track regulatory strategy with a planned BLA filing as early as 2020."

Data presented at ESMO is based on 76 patients treated with PD-1 (AGEN2034) as well as combination PD-1 and CTLA-4 (AGEN1884) regimens.

  • Agenus' anti-PD-1 (AGEN2034) and CTLA-4 (AGEN1884) reveal clinical activity across multiple solid tumors, including breast and gynecologic cancers such as cervical and ovarian.
  • Patients treated with AGEN2034 reveal a clinical benefit rate of 68% in evaluable patients with metastatic and/or locally advanced solid tumors, and in 3 of 7 evaluable patients with refractory cervical cancer.
  • Data from combination AGEN2034 plus AGEN1884 show similar trends; early clinical benefit observed in 7 of 16 evaluable patients with ovarian, breast, and soft tissue sarcoma, including a durable response in a patient with ovarian cancer.

Since the ESMO data cut-off, early evidence of clinical benefit was observed in patients with cervical cancer treated with combination AGEN2034 and AGEN1884. ESMO posters are available at
