Company News: ISA Pharmaceuticals signs R&D agreement with Shin Nippon Biomedical Laboratories
– Experiments to evaluate a novel nasal cervical cancer immunotherapeutic
ISA Pharmaceuticals B.V., a clinical-stage immunotherapy company focusing on rationally designed immunotherapeutics against cancer and persistent viral infections, today announced that its fully-owned subsidiary ISA Therapeutics B.V. has closed an R&D agreement with Japan-based Shin Nippon Biomedical Laboratories, Ltd. (SNBL) to explore a novel nasal delivery for ISA’s cervical cancer immunotherapeutic. In the experiments, ISA Pharmaceuticals’ proprietary Synthetic Long Peptide (SLP®) immunotherapeutic ISA101 will be administered via SNBL’s novel nasal drug delivery technology. SNBL´s patent-protected approach is designed to significantly enhance the absorption of powder-based nasal drugs from the nasal mucosa.
Both parties expect to obtain basic research data on a potential antigen-specific immune response.
ISA101 is ISA Pharmaceuticals´ most advanced pipeline program and designed to treat early-stage, advanced and recurrent cancers induced by HPV16 infections. ISA101 is currently administered via subcutaneous injections and has successfully completed several clinical studies in the Netherlands and Belgium for advanced and recurrent cervical cancer, as well as other early-stage HPV16-related cancers.
ISA101 consists of 13 synthetic long peptides (25-35 amino acids long) derived from the E6 and E7 oncogenic proteins of the HPV16 virus. This strain is responsible for 50% of human cervical cancers and cervical intra-epithelial neoplasias and for more than 85% of HPV-positive head and neck cancers, anal cancers and premalignant HPV-induced anal lesions (termed anal intra-epithelial neoplasia, or AIN).
In the United States, cervical cancer is the second most common cancer in women after breast cancer. In Japan, approximately 10,000 women are diagnosed for cervical cancer, and approximately 2,700 infected women die from the disease every year. Since HPV can remain persistent in the body for over a decade before cancer develops, there is a strong demand not only for prophylactic vaccines preventing HPV infections, but also for novel immunotherapeutics to treat already infected individuals.
Company News: ISA Pharmaceuticals Strengthens Patent Protection for its Lead Product ISA101
– Granted EU patent provides market exclusivity until 2028 –
ISA Pharmaceuticals B.V., a clinical-stage immunotherapy company focusing on rationally designed therapeutic vaccines against cancer and persistent viral infections, today announced it has been granted a European patent on its lead compound ISA101. The patent ensures market protection of ISA101’s active ingredient in Europe until 2028.
ISA101 is a therapeutic vaccine for the treatment of high-risk, HPV16-induced diseases. The vaccine consists of synthetic long peptides derived from the E6 and E7 oncogenic proteins of the HPV16 virus. This HPV strain is responsible, among others, for over 50% of human cervical cancers, more than 85% of HPV-positive head and neck cancers, and a variety of premalignant disorders.
The patent covers long peptides of the HPV-E6 protein, including a novel CD4+ epitope and provides exclusivity for the treatment of HPV-related diseases.
ISA101 is currently studied in the CervISA trial, a company-sponsored Phase I/II trial in cervical cancer and anal intra-epithelial neoplasia (AIN). Moreover, the vaccine has established clinical proof-of-concept by successfully completing a Phase II trial in vulvar intraepithelial neoplasia (VIN).
Company News: ISA Pharmaceuticals Initiates Phase I/II Clinical Trial With ISA101 in Women with Cervical Cancer
– Therapeutic vaccine against Human Papilloma Virus type 16 (HPV16) tested together with chemotherapy in women with HPV16-positive advanced or recurrent cervical cancer –
ISA Pharmaceuticals B.V., a clinical-stage biopharmaceutical company focusing on rationally designed therapeutic vaccines against cancer and persistent viral infections, today announced the initiation of a Phase I/II clinical study of its lead candidate ISA101 in women with HPV16-positive advanced or recurrent cervical cancer, eligible for standard chemotherapy with carboplatin and paclitaxel (CervISA study). The first patient was vaccinated this month.
ISA101 is a synthetic long peptide (SLP®) vaccine for the treatment of diseases induced by human papilloma virus (HPV) type 16, such as cervical cancer, ano-genital premalignant and malignant lesions, and head and neck cancer.
The open-label, multicenter CervISA study is designed to determine the safety and immune-modulating effects of ISA101 at different doses with or without pegylated interferon alpha in combination with carboplatin and paclitaxel.
Patients will receive up to six standard chemotherapy cycles (paclitaxel 175 mg/m2 and carboplatin AUC 6 every three weeks) and three vaccinations at different dose levels during the same period. Half the women at each dose level will also receive pegylated interferon alpha. Primary endpoints of the trial are safety and HPV-specific immune responses. The secondary endpoint is antitumor efficacy according to RECIST 1.1.
Virtually all cervical cancers are caused by HPV infections, with HPV16 being responsible for about 50-60% percent of all cases.

Therapeutic vaccine against Human Papilloma Virus type 16 (HPV16) tested in HIV-positive male patients
ISA Pharmaceuticals B.V., a clinical-stage biopharmaceutical company focusing on rationally designed, fully synthetic therapeutic vaccines against cancer and persistent viral infections, today announced the initiation of a Phase I/II clinical study of its lead candidate ISA101 in HIV-positive men suffering from anal intraepithelial neoplasia (AIN). The study is supported by ZonMw, the Dutch Organisation for Health Research and Development, and is being conducted in The Netherlands.
ISA101 is a synthetic long peptide (SLP®) vaccine for the treatment of diseases induced by human papilloma virus type 16 (HPV16), such as cervical cancer, ano-genital premalignant and malignant lesions, and head and neck cancer.
The open-label, dose-response study will be conducted in 30 HIV-positive male patients suffering from HPV16-positive high-grade AIN, who failed previous treatment. In the first dose escalation part of the trial, patients will be vaccinated with ISA101 in three dosing cohorts three times at three-week intervals, either with or without administration of peg-interferon-α on the day of vaccination. An additional group of 15 patients will be treated with the optimal ISA101 schedule. Primary clinical endpoints will be toxicity and safety as well as regression of lesions at 3, 6 and 12 months. Secondary endpoints are regression of lesions at 18 months and HPV16-specific immunity in the blood.
AIN is caused by infection with high-risk papilloma viruses (HPV) and known as a cancer precursor lesion that can lead to the development of anal cancer. AIN of any grade has been reported to be present in 63–81% of HIV-positive men, and high-grade disease (AIN 2 or 3) in 25–52%. The majority (approximately 60%) of high-grade AIN is caused by HPV16. Incidence of anal cancer has increased significantly since 1997 in both men and women, and especially in HIV-positive men. This is assumed to be a result of the significantly prolonged life span of HIV-positive patients. Therefore, early diagnosis and treatment of AIN is important to prevent malignancy. At present, there is no systemic treatment.
