Disclosed is a ratchet strap and buckle assembly comprising an adjustment ratchet strap comprising a ratchet strap end, and a plurality of ratchet teeth arranged thereon and a single-piece buckle having a locking tooth and a flexible top element, wherein the single-piece buckle comprises a passageway for the ratchet strap end to be inserted therein, and wherein the flexible top element is configured to engage with at least one of the plurality of ratchet teeth using the locking tooth upon insertion.

Simplified ratchet strap and buckle assembly

The invention provides methods and compositions for the treatment of primary, metastatic, and residual cancer in mammals, and more particularly, the use of materials such as whole cells and derivatives and portions thereof to stimulate the immune system to attack cancer.

Human prostate cell lines in cancer treatment

Combinations of cell lines are provided for allogeneic immunotherapy agents in the treatment of cancer. Cancer vaccines generally have been limited to the use of cells that contain at least some tumor specific antigens ('TSAs') and/or tumor associated antigens ('TAAs') having shared identity with antigens in a targeted tumor. In such cases, tumor cells often are utilized as a starting point on the premise that only tumor cells will contain TSAs or TAAs or relevance, and the tissue origins of the cells are matched to the tumor site in patients. A primary aspect of the invention is the use of immortalised normal, non-malignant cells, in combination with primary and/or metastatic tumor cells, as the basis of an allogeneic cell cancer vaccine. Normal cells do not posses TSAs or relevant concentrations of TAAs and hence it is surprising that normal cells are effective as anti-cancer vaccines when administered in combination with primary and/or metastatic tumor cells. More surprisingly, a three way combination of cells obtained from metastasized cells, non metastasized tumor and cells from a normal cell line provided good therapy. For prostate cancer, for example, a vaccine may be based on one or a combination of different immortalized normal cell lines derived from the prostate according to parameters described herein. The cell lines may be lethally irradiated with, for example, gamma irradiation at 50-300 Gy to ensure that they are replication incompetent prior to use.

The invention here relates to a product comprised of a cell line or lines intended for use as an allogeneic immunotherapy agent for the treatment of cancer in mammals and humans. All of the studies of cell-based cancer vaccines to date have one feature in common, namely the intention to use cells that contain at least some TSAs and/or TAAs that are shared with the antigens present in patients' tumor. In each case, tumor cells are utilized as the starting point on the premise that only tumor cells will contain TSAs or TAAs of relevance, and the tissue origins of the cells are matched to the tumor site in patients.

Use of human prostrate cell lines in prostate cancer treatment

The invention relates to a product comprised of specific combinations of cell lines intended for use as an allogeneic immunotherapy agent for the treatment of prostate cancer in humans. The heterogeneity of the immunotherapeutic matches the heterogeneity of the antigenic profile in the target prostate cancer and immunises the recipients with many of the potential TAA and TSA which are expressed at various stages of the disease. The invention discloses a vaccine comprising a combination of three different cell lines prepared from primary or metastatic prostate cancer biopsy material. The cell lines are lethally irradiated utilising gamma irradiation at 50-300 Gy to ensure that they are replication incompetent.
