Patent number: 10436788Abstract: Described herein are compositions and methods of use of anti-Trop-2 antibodies or antigen-binding fragment thereof to isolate, enrich, detect, diagnose and/or characterize circulating tumor cells (CTCs) from patients with a Trop-2 positive cancer. Preferably, the antibody is an RS7, 162-46.2 or MAB650 antibody. The compositions and methods are of use to detect, diagnose and/or treat metastatic Trop-2+ cancers, such as breast, ovarian, cervical, endometrial, lung, prostate, colon, rectum, stomach, esophageal, bladder, renal, pancreatic, thyroid, epithelial or head-and-neck cancer.Type: GrantFiled: September 18, 2017Date of Patent: October 8, 2019Assignee: Immunomedics, Inc.Inventors: David M. Goldenberg, Hans J. Hansen, Chien-Hsing Chang

Patent number: 10413539Abstract: The present invention relates to therapeutic ADCs comprising SN-38 attached to an anti-Trop-2 antibody or antigen-binding antibody fragment. The ADC may be administered at a dosage of between 4 mg/kg and 18 mg/kg, preferably 4, 6, 8, 9, 10, 12, 16 or 18 mg/kg, most preferably 8 to 10 mg/kg. When administered at specified dosages and schedules, the ADC can reduce solid tumors in size, reduce or eliminate metastases and is effective to treat cancers resistant to standard therapies, such as radiation therapy, chemotherapy or immunotherapy. Preferably, the ADC is administered in combination with one or more other therapeutic agents, such as a PARP inhibitor, a microtubule inhibitor, a Bruton kinase inhibitor or a PI3K inhibitor. Most preferably, the ADC is of use for treating a Trop-2 expressing cancer, such as metastatic urothelial cancer.Type: GrantFiled: November 22, 2017Date of Patent: September 17, 2019Assignee: Immunomedics, Inc.Inventors: Serengulam V. Govindan, David M. Goldenberg

Patent number: 10301365Abstract: The present invention provides isolated Met e 1 polypeptides and nucleic acids encoding the isolated polypeptides that can prevent and/or alleviate an allergic response to shellfish tropomyosin. The polypeptides are based on the shrimp tropomyosin Met e 1 protein and have been modified to act as hypoallergens. The Met e 1 hypoallergens have low to no IgE reactivity or allergenicity and are useful for prophylactic and/or therapeutic treatment of shellfish allergy in subject in need thereof.Type: GrantFiled: October 3, 2016Date of Patent: May 28, 2019Assignees: The Chinese University of Hong Kong, The Regents of the University of CaliforniaInventors: Ka Hou Chu, Patrick S.
