In my current situation where I'm very severe, eg my mum spoke to me for a minute last night and I started having that same feeling welling up. Is that not the case? I saw people describe their PEM as I thought of crashes. I thought that was PEM (just the milder symptoms) and crashing was the first part, where you have this intense build up of nasty symptoms that seem to lead to PEM in the following days. I'd then get a bit of PEM - ie more brain fog, a bit more tired, nothing extreme, for a number of days. During this I'd have a feeling of discomfort/anxiety gradually well up in my chest and then I'd have to go lie down feeling nasty. All other authors have declared no conflicts of interest.I know there have been a few threads on this but I am still a bit confused and finding it all very vague, hopefully someone can help clarify for me.īack when I was housebound I'd say do a task that was too much eg cooking a proper dinner.

Secondary endpoints are objective response rate and progression free survival. Tumor biopsies and blood samples including PBMCs are taken at baseline, wk 6, 9, 12, 18 and in case of progression. Primary endpoints are SUSARs and adherence to the study timeline, the intra-patient alteration in intratumoral CD8+ T cells and the percentage PD1+ CD8+ T cells in the peripheral blood. All cohorts continue afterwards with PEM for up to 2 years. After 6 wks the patients will be randomized (stratified according their LDH level) to continue PEM for up to 2 years (cohort 1), or to one of the experimental cohorts receiving either dabrafenib 150mg BID + trametinib 2mg QD two times intermittent for 1 wk (cohort 2), two times intermittent for 2 wks (cohort 3), or continuous for 6 wks (cohort 4). Stage IV BRAFV600E/K mutation positive melanoma patients, naïve for IT and TT, will start treatment with PEM 200mg q3wk. The primary objective is to explore safety, feasibility and the immune-activating capacity of the different regimens.
Whats the difference between pterm and pem trial#
The IMPemBra trial will address this question, comparing PEM monotherapy with combination schemes of intermittent/short-term BRAFi + MEKi plus PEM. This raises the question which time period of MAPK pathway inhibition is optimal for combination with anti-PD-1. Analysis of biopsies of patients during TT indicate that long-term TT might be counterproductive, as T cell infiltration decreases in some patients already beyond 2 weeks. Recently we have published preclinical data, showing that short-time TT induces strong T cell infiltration and is synergistic with PD-1 blockade. However, high toxicity rates have been observed, revealing PD-1 blockade currently being the only possible combination partner for TT. CTLA-4 or PD-1 blockade are currently tested in several phase1/2 trials with the aim to improve response rate and response duration in melanoma patients with a BRAFV600 mutation.
