Brief Summary:
In their Magrolimab research project the investigators want to find out whether the new drug Magrolimab in combination with conventional chemotherapy is well tolerated and whether survival or progression-free survival improves
Detailed Description:
About 10 of the patients with urothelial carcinoma of the bladder present with advanced disease at time of diagnosis The five-year overall survival is poor 13 as treatment options are limited to platinum-based chemotherapy and immune checkpoint inhibitors Therefore new therapeutic approaches are urgently needed
Stimulation of the innate immune response to cancer cells using macrophages to attack tumor cells represents a novel approach of cancer immunotherapy One mechanism used by tumor cells to prevent phagocytosis and thus avoid clearance by the immune system is to up regulate dont eat me signals such as CD47 Blockade of CD47 represents a novel immunotherapy allowing the immune system to eliminate cancer cells Cytotoxic chemotherapy in particular Gemcitabine is known to upregulate calreticulin which is a so called eat me signal Consequently a combination of Gemcitabine with an anit-CD47 antibody could potentiate the tumor-cell killing effects
Magrolimab is a first-in-class fully humanized monoclonal antibody blocking CD47 and currently investigated as an immunotherapy in solid as well as hematologic malignancies in several phase 1 - 3 clinical trials Furthermore Magrolimab as a novel myeloid specific immune checkpoint inhibitor could be the urgently needed new therapeutic weapon for bladder cancer treatment if it proves to add a significant therapeutic benefit to conventional chemotherapy in advanced muscle invasive bladder cancer The expected benefit of combining chemotherapy with Magrolimab might be manifold
It could result in durable systemic anti-cancer responses and subsequently increase disease free and overall survival
It could increase the response rate and prolong survival in the metastatic setting
In case of positive results of this trial the investigators could expand this approach to the peri-operative setting
In the neoadjuvant setting it could increase the rate of pathologic complete remission pCR ypT0 and subsequently reduce the risk of local recurrence and bladder cancer related death
In the adjuvant setting it could induce antitumor immune response in micro metastases and subsequently reduce risk of local recurrence and improve cancer specific survival
The primary endpoint of the trial is incidence of adverse events AEs and laboratory abnormalities according to the National Cancer Institute NCI Common Terminology Criteria for Adverse Events CTCAE Version 50 Secondary endpoints are
PFS from date of dose initiation as determined by investigator assessment per RECIST Version 11
DOR defined as time from first documentation of complete response or partial response to the earliest date of documented disease progression per RECIST Version 11 or death from any cause whichever occurs first as determined by investigator assessment
OS defined as date of dose initiation to death from any cause
