    A new cancer treatment for adults with stomach (gastric) and gastro oesophageal junction cancer has been approved by the Medicines and Healthcare products Regulatory Agency (MHRA) this week. According to the MHRA, Zolbetuximab, a monoclonal antibody, is designed to target and destroy specific cancer cells, offering a new option for patients whose cancer is inoperable or has spread. The new targeted cancer treatment for gastric and gastro-oesophageal junction cancer is administered intravenously in combination with standard chemotherapy regimens and is typically given every two to three weeks under the supervision of an experienced oncologist. Zolbetuximab is indicated for patients whose tumors are positive for the Claudin18.2 (CLDN18.2) protein and negative for the Human epidermal growth factor receptor 2 (HER2) protein.

VAE mistletoe cancer monoclonal antibodies mAB IL-12 NK cells

  • Among the most encouraging mAb is trastuzumab, which targets the human epidermal growth factor receptor 2 and is indicated in the treatment of breast cancer
  • bevacizumab, which inhibits vascular endothelial growth factor and is indicated in the treatment of a range of diseases, including colorectal, lung, and ovarian cancer3; and cetuximab, which blocks the epidermal growth factor receptor and is indicated in the treatment of colorectal and lung cancer
  • Viscum album L (VA or European mistletoe) preparations are widely used as additive cancer therapy in Europe, especially in German-speaking countries, and have been associated with a reduction in chemotherapy-related adverse drug reactions and increased HRQL

  • leading to enhancement of interleukin-12 secretion and natural killer cell function
  • Helixor VA preparations
  • A multivariable GEE model indicated that the odds for patients experiencing an AE following mAb therapy were nearly 5 times higher compared with that for mAb plus VA
  • VA preparations (Iscador Ltd) did not inhibit chemotherapy-induced cytostasis or cytotoxicity and showed an additive inhibitory effect at higher concentrations of VA.
  • previous in vitro investigations have shown that VA preparations have either no or minor effects on a range of CYPs, suggesting that VA-drug interactions based on drug metabolism are unlikely
  • mAb do not undergo hepatic metabolism but undergo proteolytic catabolism throughout the body

    VAE therapy found to reduce adverse events in those receiving monoclonal Ab therapy.

cancer anal cancer nivolumab immunotherapy

  • Patients received a median of six doses of nivolumab
  • four of the first 12 patients had partial responses
  • Nine (24% [95% CI 15–33]) of 37 patients achieved a response (seven partial responses and two complete responses
  • ...16 more annotations...
  • no treatment-related deaths
  • the most common adverse events were anaemia (26 [70%]), fatigue (25 [68%]), and rash
  • hypothyroidism
  • hypothyroidism
  • nivolumab-related autoimmune hypothyroidism, which resolved after a short course of corticosteroids
  • No grade 3 or 4 adverse events occurred
  • Nivolumab resulted in objective responses in 24% of patients with metastatic SCCA
  • Historically, doublet chemotherapy with cisplatin and fluorouracil has been the most common treatment for patients with metastatic SCCA
  • our results suggest that immune checkpoint blockade agents might extend overall survival beyond currently available therapies, especially if provided early in the disease treatment course
  • the dose of nivolumab we used differs from the 2016 recommendation of a fixed 240 mg every 2 weeks
  • 25% of patients develop distant metastases
  • most patients with localised SCCA are cured by chemoradiation
  • More than 90% of cases of SCCA are linked to prior infection with human papillomavirus (HPV)
  • Within tumour cells, HPV oncoproteins are immunogenic and can trigger an anti-tumour host immune response by recruitment of tumour-infiltrating lymphocytes
  • Tumour cells express PD-L1 and, on binding its inhibitory receptor PD-1 on the surface of T cells, downregulate T-cell activation and thwart the local anti-tumour immune response
  • Nivolumab is a humanised monoclonal antibody against PD-1 that disrupts this interaction, enabling T-cell cytotoxicity. It has activity as a monotherapy in advanced solid cancers, such as head and neck cancer, melanoma, non-small-cell lung cancer, and renal cell carcinoma

    study finds nivolumab helpful in some patients with surgically unresectable or metastatic anal cancer.  The dose used was 3 mg/kg every 2 weeks.
