I can’t give medical advice, but I can hopefully provide a little insight. If he was only on the Venclexta a short time before it was put on hold, I would think it’s fair to say that the medication wasn’t given enough time to work. It can take a month or month and a half to see results. If the doctor has recommended to try it again, it may be worth a try.
I have seen patients’ therapy be on hold for months due to infection. It can be a really tough spot. His body struggles harder to fully fight the infection because of the MDS and you can’t fight the MDS because of the infection.
You and your husband will be in our thoughts. Please reach out if there is anything we can do.
