An Assessment of an Attenuated Live Listeria Vaccine in CIN 2+

2014-07-24 14:05:52 | BioPortfolio


Cervical cancer is associated with Human Papilloma Virus. About 57% of cervical cancer is the result of infection by Human Papilloma Virus strain 16 (HPV-16). HPV is a very common virus that can affect the cells of the cervix. E7 is a substance that is made by the HPV virus which causes cervical cancer. The purpose of the study is to test the safety, tolerability (how the drug makes you feel), immunology (effects on the immune system) and efficacy (disease curing effects) of a vaccine called Lovaxin C against E7. The vaccine is designed to cause the immune system to react against the E7 substance in a manner that is intended to reverse the changes to the cervix and prevent cervical cancer from occurring.


Worldwide, many women carry HPV and cervical cancer is the leading cancer killer of women under the age of 50. Although its consequences are considerably less severe in the US, it leads to considerable morbidity. Many published clinical trials describe the immunotherapeutic treatment of early stage, pre-invasive, cervical cancer. It is widely recognized that immunotherapies are most effective in early stage disease because the immune system is least debilitated and disease burden is lowest. Invasive cervical cancer is preceded by a long, slowly progressive, pre-invasive phase termed Cervical Intraepithelial Neoplasia (CIN), which allows for this therapeutic approach. An ideal therapy would result in the remission of CIN 2/3 without damage to cervical tissue. A National Institute of Cancer panel charged with achieving consensus on this issue concluded that a non-surgical medical treatment for this indication would be valuable

The primary objectives of this trial are to test three doses of Lovaxin C to determine if vaccination with Lovaxin C in women with CIN 2/3 for whom surgery is indicated can safely reverse the disease compared to placebo treated control patients.

An earlier Phase 1/2 trial of Lovaxin-C in late stage metastatic cervical cancer used a regimen of two doses given with a 28-day interval. That regimen was shown to be safe and to generate reduction in tumor burdens in some patients. In this trial we will treat earlier stage disease in healthier patients with better immune systems, will use the same and lower doses as given before, but add an additional dosing to the regimen by administering the lowest dose that we assessed previously and by adding a third vaccination to the prior regimen. Unlike the phase 1 trial in which 2 doses were given with a 3 week separation, dosing in the proposed trial will be separated by 4-week intervals.

Medical and Biotech [MESH] Definitions

Morphological abnormalities of the cervical EPITHELIUM, usually revealed in PAP SMEAR, which do not meet the criteria for squamous CERVICAL INTRAEPITHELIAL NEOPLASIA or SQUAMOUS CELL CARCINOMAS of the CERVIX . It may be a sign of infection with certain types of human papillomavirus (HPV).or sign of a benign (not cancer) growth, such as a cyst or polyp or, in menopausal women, of low hormone levels. More testing, such as HPV test, may be needed.

A malignancy arising in uterine cervical epithelium and confined thereto, representing a continuum of histological changes ranging from well-differentiated CIN 1 (formerly, mild dysplasia) to severe dysplasia/carcinoma in situ, CIN 3. The lesion arises at the squamocolumnar cell junction at the transformation zone of the endocervical canal, with a variable tendency to develop invasive epidermoid carcinoma, a tendency that is enhanced by concomitant human papillomaviral infection. (Segen, Dictionary of Modern Medicine, 1992)

A premalignant change arising in the prostatic epithelium, regarded as the most important and most likely precursor of prostatic adenocarcinoma. The neoplasia takes the form of an intra-acinar or ductal proliferation of secretory cells with unequivocal nuclear anaplasia, which corresponds to nuclear grade 2 and 3 invasive prostate cancer.

A cytological test finding often from PAP SMEARS that shows abnormal lesions of SQUAMOUS EPITHELIAL CELLS of the CERVIX. It is a diagnostic criterion used in the Bethesda System for UTERINE CERVICAL NEOPLASMS and represents the PAP TEST result that is abnormal. Although squamous intraepithelial lesions test result does not mean UTERINE CERVICAL NEOPLASMS it requires follow-ups (e.g., HPV DNA TESTS; and COLPOSCOPY).

A network of nerve fibers originating in the upper four cervical spinal cord segments. The cervical plexus distributes cutaneous nerves to parts of the neck, shoulders, and back of the head, and motor fibers to muscles of the cervical spinal column, infrahyoid muscles, and the diaphragm.
