Antibody compositions and methods for inhibition of the effects of gonadotropin hormones are provided. Methods for treating cancer and methods for regulating fertility are provided by administration of the antibody compositions to a mammalian subject in need thereof.

Antibody compositions, methods for treating neoplastic disease and methods for regulating fertility

Compositions for stimulating the immune system and for treating malignancies associated with overexpression of the HER-2 protein are provided. Such compositions include immunogenic epitopes of the HER-2 proteins and chimeric and multivalent peptides which comprise such epitopes. The present invention also relates to polynucleotides which encode the chimeric peptides. Also provided are pharmaceutical compositions comprising such immunogenic compositions. Methods for stimulating an immune response to HER-2 protein are provided. Methods for treating breast cancer, ovarian cancer, prostate cancer, colon cancer and lung cancer are provided.

Polypeptides and polynucleotides for enhancing immune reactivity to HER-2 protein

Disclosed is a method for improving the treatment of a cancer patient which is undergoing (adjuvant) chemotherapy. Prior to or concomitant with the patient receiving adjuvant chemotherapy, the patient is administered mitogenically stimulated lymph node lymphocytes or the supernatant therefrom. The lymph node lymphocytes are patient excised lymph node lymphocytes enriched in tumor reactive cells, such as CD4+ tumor reactive cells. Radiolabeled locators (e.g., antibodies) can be used along with a portable radiation detector to intraoperatively determine which lymph nodes bear lymph node lymphocytes enriched in tumor reactive cells. The patient excised lymph node lymphocytes enriched in tumor reactive cells then are subjected to mitogenic stimulation for their expansion and administration to the patient.

Modulation of the sensitivity of tumor cells to chemotherapeutics

The present invention is directed to a method for reliably determining lymph nodes enriched in tumor reactive cells, e.g., CD4+tumor-specific lymphocytes. This method includes the steps of administering to a patient an effective amount of a radiolabeled locator which specifically binds a marker produced by or associated with neoplastic tissue. Time is permitted to elapse following the administration for the radiolabeled locator to preferentially concentrate in any neoplastic tissue and for unbound radiolabeled locator to be cleared, so as to increase the ratio of photon emissions from neoplastic tissue to background photon emissions in the patient. After the time has elapsed, the patient is accessed with a radiation detection probe for determining lymph node sites exhibiting accretion of the radiolabeled locator by detecting with the probe elevated levels of radiation at the lymph node sites. The lymph node sites exhibiting such elevated levels of radiation are removed and subjected to gross visual analysis, though such sites alternatively may be subjected to histological analysis. Those determined and removed lymph nodes that also are determined to be tumor-free by gross observation or free of gross metastatic disease are selected and cultured to proliferate tumor reactive cells. The selected lymph nodes are subjected to mitogenic stimulation. The lymph nodes are cultured in the presence of Interleukin-2, anti-CD.sub.3 monoclonal antibody, and neoplastic tissue which may be autologous or allogeneic tumor. The tumor reactive cells, proliferated can be used with adoptive immunotherapy regimens for mitigating the progression of tumor.

Determination of lymph nodes enriched in tumor reactive cells their

A method for improving interleukin-2 induced lymphocyte killing of cancer cells comprises administering to a patient having cancer an effective amount of at least one aci-reductone compound containing a --C(OH).dbd.C(OH)--C.dbd.O redox functionality or a physiologically acceptable salt thereof together with a physiologically acceptable carrier or excipient.
