Vaccibody AS announced today vaccination of the first patient in its multicentre trial VB C-01 – an exploratory, open-label, multicenter phase I/IIa study VB10.16 immunotherapy for the treatment of high grade Cervical Intraepithelial Neoplasia (CIN 2/3) caused by human papillomavirus 16 (HPV 16).
Patients will receive intramuscular vaccinations of VB10.16 at three different time points. Two different dosing schedules will be evaluated during the first phase of the study in patients diagnosed with CIN 2, the best vaccination schedule will then be evaluated in the second phase in both CIN 2 and CIN 3 patients. The primary objective of the study is to evaluate the safety and tolerability of three doses of 3 mg VB10.16. The secondary objectives are to assess T cell mediated immune responses in the peripheral blood as well as in the pre-malignant tissue of the CIN 2/3 lesions and to evaluate early signs of efficacy by means of HPV clearance and CIN regression.
Martin Bonde, CEO of Vaccibody, commented: We are pleased to announce commencement of patient treatment in this first clinical trial with Vaccibody’s lead product VB10.16. Surgery is currently the only available therapy to remove abnormal cervical lesions caused by human papillomavirus and thereby stop the progression to cervical cancer. We are hopeful that VB10.16 immunotherapy can help change this treatment paradigm by offering a safe and efficacious alternative in the form of a therapeutic HPV vaccine.
Principal investigator, Prof. Dr. med. Karl Ulrich Petry, Department of Obstetrics & Gynaecology Klinikum Wolfsburg commented: The scientific approach of this well designed clinical study offers the chance to get a thorough understanding on how patients respond to VB10.16 immunotherapy. The first dosing of a patient has just been performed successfully in our hospital . We are convinced that patients with CIN 2 and CIN 3 will be very motivated to participate in the study to test this therapeutic vaccination as it might offer a non-invasive treatment option avoiding the side effects associated with surgical excision of the affected tissue and potentially also cure the underlying HPV infection and prevent recurrence. Furthermore, VB10.16 could also protect from other HPV16 induced cancers.
The company’s lead product, VB10.16, is a therapeutic DNA vaccine developed to treat human papillomavirus type 16 (HPV16) induced pre-malignancies and malignancies.
About Cervical Intraepithelial Neoplasia (CIN) and Cervical Cancer
Per year approximately 530,000 women are diagnosed with cervical cancer worldwide and over 275,000 women die of the disease annually. Invasive cervical cancer is preceded by a long phase of pre-invasive disease called Cervical Intraepithelial Neoplasia (CIN). Globally the number of high grade lesions (CIN 2/3) the immediate precursors to malignancy, is estimated to be in the range of 10 million.
Virtually all cervical cancers are caused by high risk HPV types. Among the different high risk HPV types known, HPV16 has been reported to be the most common genotype in high grade cervical intraepithelial neoplasia. It can be detected in up to 60 % of all cervical cancers, especially in younger women and it has also been found to play an essential role in the development of several other cancer types (approximately 90% of anal cancers; 40% of penile, vaginal, and vulvar cancers; 25% of oral cavity cancers and 35% of oropharyngeal cancers).
Current standard therapy for CIN 2/3 varies between countries and regions and often involves surgical removal of the affected tissue. These invasive procedures are associated with bleeding, infection, cervical stenosis, scarring and most importantly pre-term deliveries in subsequent pregnancies. As a result, there is a significant need for an effective therapeutic vaccine to treat existing HPV infection and associated pre-malignancies and malignancies of the cervix and thereby prevent the development of cervical cancer caused by human papillomavirus.
About Vaccibody AS
Vaccibody is a biopharmaceutical company dedicated to the discovery and development of novel immunotherapies, prophylactic and therapeutic vaccines which target cancer and infectious diseases, for human and veterinary use. Vaccibody’s lead program is focused on VB10.16, a therapeutic DNA vaccine against HPV16 induced pre-malignancies and malignancies. The first-in-human study will evaluate the safety and immunogenicity of VB10.16 in women with high grade cervical intraepithelial neoplasia (HSIL; CIN 2/3).
