I am sorry to hear that BCG shortage is affecting your close friend’s family. I empathize the anxiety it is causing to you and your friend’s family. Unfortunately, I hear and there about the shortage affecting the treatment. I don’t know why patients have to shop around when the patients have no information about the supply chain of BCG and which hospital has surplus BCG to share. I get upset about it. But, that is what patients are doing so I have read.
Anyway, there are two companies in India who manufacture BCG for bladder cancer,their BCGs are exported mostly to low income countries. But, the FDA does not allow the use of it in the US. Technically, BCG manufactured in the US and in other BCG manufactured in other countries are different. They all originate from the same BCG which was developed in early 1900 in Paris, France. As the master seeds are brought into different countries, their manufacturing environments are different and mutations could have happened because BCG is live bacteria. To deal with the shortage in the US, urologists decided to compare BCG by MERCK and BCG by Tokyo BCG lab and they started a clinical trial almost 5 years ago for 1000 patients. But they stopped recruiting now and the first report is due on March 2023. I do not know why they do not expertise the approval as they must have sufficient data to approve it. This also frustrates me when we still see the impact of the shortage.
I do not know the pathology report of your friend’s son from the tissue sample the urologist took out when he did remove the tumor from the bladder of your friend’s son, so I cannot take how critical BCG as the treatment at this point.
It is noted that the urologist took out the tumor from your friend’s son, So, he is cancer free now.
But, clinically, the stats show his type of cancer tend to reappear some place in the lining of the bladder and this is BCG for to prevent it.
If indeed, BCG is not going to be available for lengthy period, some urologist may use different treatment till BC becomes available. I know in this forum, a patient in Chicago was prescribed Gemcitabine plus Docetaxel chemo agents instilled into his bladder when BCG became unavailable during BCG maintenance treatment and went back to BCG again. There were no reappearing of cancer during this period.
