New treatment option for dMMR endometrial cancer

Dostarmilab (brand name Jemperli), a monoclonal antibody, has received accelerated approval for recurrent/advanced endometrial cancer associated with deficient mismatch repair (dMMR) and previously treated with platinum-containing chemotherapy.

Here's the press release: PD-1 Inhibitor Approved for dMMR Endometrial Cancer

I believe this is for cancers with microsatellite instability (like Lynch syndrome). Maybe someone else familiar with dMMR can confirm this? I'm microsatellite stable, so I don't know about dMMR.

    MSI-H/dMMR

    My understanding is that microsatellite instability (MSI-H) results from impaired DNA mismatch repair (dMMR). While some instances of MSI-H/dMMR are caused by Lynch Syndrome, others result from somatic mutations in the tumor itself.

    As someone with Lynch, I'm always interested in new treatments for MSI-H/dMMR. Thanks for posting,

    I read this as well

    I am MSI which led to testing of the MLH1 gene for Lynch. When it came back positive for methylation Lynch was ruled out. So I am looking at dMMR even though the methylation occurred--methylation can have the same effect--the gene doesn't work and the end result is that chemo doesn't work. So Keytruda is approved for dMMR and MSI-H tumors and Jemperli is approved for dMMR. I think they work roughly the same way. I feel like I need to take a biology class!

    Update

    Got my first Pembro infusion this week. So far side effect free. Interesting note relevant to this thread. My docs tried to get this new drug because my most recent tumor test showed MSI undetermined. But I do have the BRCA 2 mutation. So the decision was made to start Pembro and move to the dostarlimab when it becomes available. Fingers crossed.

    I am dMMR based on MLH1

    I am dMMR based on MLH1 methylation positive. My MSI status is now considered inconcludive. Keytruda (Pembrolaziamb) became option since it also addresses dMMR.

    Good luck with your new treatment

    Hi Deb,

     

    I'm here to support my mom and I've been following your posts--it's good to hear you started a new treatment, I hope it goes well and you stay side effect-free.  I'll be sending you good thoughts that you see results soon!

    I had my first Keytruda

    I had my first Keytruda infusion on 12 May. So far so good. Only some chest pain. BP is finally down so doc is letting me come off the amlodipine which was likely causing lower leg edema. Not comfortable when combined with minor neuropathy!

    Will keep all posted on progress especially if I get moved to dostarlimab when it's more widely available.

    Cheers,

    Deb

    Move to dostarlimab

    Had my second Keytruda infusion last Tuesday then hightailed it to Florida for a family get together. It has been great! I chose to get a port which I didn't do for chemo; the thinking was I would only have 6 sessions and press on. Of course it didn't work that way. I've had almost no side effects so far another than chest/rib cage discomfort. I keep feeling like I have a bad stitch when I breathe but the feels g varies a lot through the day. I found Alleve helps. I will say that I'm almost hoping for a sign this stuff is doing something after the chemo failure. Ah well. I have an X-ray scheduled for 12 July to check progress after #3 and the day before #4.

    Here's the interesting part. The onc nurse called me and said we'll be switching to dostarlimab for #4. I will keep everyone posted and on the journey through immunotherapy. I feel very good but have noticed some coughing generated by heavy breathing. The ureteral stent is keeping me from running but I'm still walking miles and cycling as much as I can.

    I hope everyone is in good health as we break out of our national nightmare!

    Hugs to all,

    Deb

    Thanks for the great update

    Thanks for the great update Deb. I hope you have an amazing trip while in Florida. 

    Here's to looking forward to positive progress before your #4!
