41 results about "Microtubule Inhibitor" patented technology

The present invention relates to combination therapy with drugs, such as microtubule inhibitors, PARP inhibitors, Bruton kinase inhibitors or PI3K inhibitors, with antibodies or immunoconjugates against HLA-DR or Trop-2. Where immunoconjugates are used, they preferably incorporate SN-38 or pro-2PDOX. The immunoconjugate may be administered at a dosage of between 1 mg / kg and 18 mg / kg, preferably 4, 6, 8, 9, 10, 12, 16 or 18 mg / kg, more preferably 8 or 10 mg / kg. The combination therapy 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 combination therapy has an additive effect on inhibiting tumor growth. Most preferably, the combination therapy has a synergistic effect on inhibiting tumor growth.

The invention features a method for treating a patient diagnosed with, or at risk of developing, an iminunoinflainpiatory disorder by administering a non-steroidal immunophilin-dependent immunosuppressant (NsIDI) and a Group A enhancer (e.g., antifungal agent, antigout agent, anti-infective agent, antiprotozoal agent, antiviral agent, humectant, sunscreen, vitamin D compound, microtubuline inhibitor, or zinc salt) or analog or metabolite thereof to the patient. The invention also features a pharmaceutical composition containing an NsIDI and Group A enhancer or analog or metabolite thereof for the treatment or prevention of an immunoinflammatory disorder.

The present invention relates to combination therapy with ADCs against a tumor-associated antigen, such as Trop-2, and drugs, such as microtubule inhibitors and / or PARP inhibitors. Where ADCs are used, they preferably incorporate SN-38 or another drug that induces DNA strand breaks. Preferably, the combination of ADC and PARPi or microtubule inhibitor exhibits synergistic effects against the cancer. The combination therapy 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.

Current approaches for treating cancer are limited, in part, by the inability of drugs to affect the poorly vascularized regions of tumors. We have found that spores of anaerobic bacteria in combination with agents which interact with microtubules can cause the destruction of both the vascular and avascular compartments of tumors. Two classes of microtubule inhibitors were found to exert markedly different effects. Some agents that inhibited microtubule synthesis, such as vinorelbine, caused rapid, massive hemorrhagic necrosis when used in combination with spores. In contrast, agents that stabilized microtubules, such as the taxane docetaxel, resulted in slow tumor regressions that killed most neoplastic cells. Remaining cells in the poorly perfused regions of tumors could be eradicated by sponzlated bacteria. Mechanistic studies showed that the microtubule destabilizers, but not the microtubule stabilizers, radically reduced blood flow to tumors, thereby enlarging the hypoxic niche in which spores could germinate. A single intravenous injection of spores plus selected microtubule-interacting agents was able to cause regressions of several tumors in the absence of excessive toxicity.

Synthetic peptides containing an ankyrin repeat-like motif or portion thereof and mimetics thereof which interact with synuclein-gamma (SNCG) and reduce SNCG-mediated resistance of SNCG-expressing cancer cells to treatment with anticancer drugs or inhibit tumorigenesis and cancer cell proliferation are provided. Compositions containing these peptides, portions thereof or mimetics thereof are also provided. Methods for use of these peptides or portions thereof, compositions, and mimetics thereof in potentiating efficacy of anticancer drugs, in particular microtubule inhibitors and hormonal cancer therapies, and in treating cancer are also provided.

The present invention provides, inter alia, methods for treating or ameliorating the effects of a disease, such as cancer, in a subject. The methods include: administering to a subject in need thereof (a) a therapeutically effective amount of a microtubule inhibitor; and (b) a therapeutically effective amount of a monoclonal antibody or antigen binding fragment thereof, wherein the monoclonal antibody contains: (i) a heavy chain variable region (VH), which includes an amino acid sequence selected from SEQ ID NO:1, SEQ ID NO:3, SEQ ID NO:5, and SEQ ID NO:7; and (ii) a light chain variable region (VL), which includes an amino acid sequence selected from SEQ ID NO:2, SEQ ID NO:4, SEQ ID NO:6, and SEQ ID NO:8. Compositions, including pharmaceutical compositions, and kits for treating diseases, such as cancer, are also provided herein.
