Describes the outcome of an investigator sponsored trial conducted at MD Anderson Cancer Center in patients suffering from advanced HPV16 positive Head and Neck cancer, combining ISA101 with nivolumab. Data demonstrate that the ORR of 36% in patients with oropharyngeal cancer compares favourably to the ORR of 16% demonstrated for nivolumab monotherapy in patients with p16-positive platin-refractory oropharyngeal cancer participating in the in Checkmate 141 study.

Melief CJ et al. “Strong vaccine responses during chemotherapy are
associated with prolonged cancer survival” Science Translational Medicine 12, March 2020.

Describes the results of the CervISA study. This was an open label, phase 2 study in patients with late stage HPV16 positive cervical cancer. Seventy-seven patients were treated with ISA Pharma’s lead product, ISA101b, an HPV16-specific immunotherapeutic agent, in combination with standard-of-care (SoC) chemotherapy (carboplatin/paclitaxel). The addition of ISA101b to SoC chemotherapy led to a strong and highly specific anti-tumor immune response and significant improvement of patient survival in responding patients .

Demonstrates that vaccination with ISA101 induces objective partial or complete histological regression of the lesion in more than 50% of the patients and as such is an effective means to treat VIN that may prevent surgical mutilation.

Van der Sluis TC, et al., Melief CJ. “Vaccine-induced Tumor Necrosis Factor producing T cells synergize with cisplatin to promote tumor cell death.” Clin Cancer Res. 2015 21(4): 781-794

Describes the mechanism of the synergy of peptide vaccination with cisplatin, which render tumor cells more susceptible to cisplatin-mediated apoptosis.

Kenter GG, et al., Melief CJ. “Vaccination against HPV-16 oncoproteins for vulvar intraepithelial neoplasia.” N Engl J Med. 2009 Nov 5;361(19):1838-47

Describes the proof-of-concept established in our first trial in HPV-16 induced pre-cancerous neoplasia. ISA was the first to demonstrate a correlation between immune responses and clinical responses.
