Details and patient eligibility
About
Pembrolizumab will have significant clinical activity in patients with Intermediate and high risk MF, advanced PV who have been resistant, failed or are intolerant to JAK2 inhibitor therapy and the activity may be enhanced in combination with JAK2 inhibition by Ruxolitinib; similarly MDS/MPN and CMML patients for who no standard therapies are available will exhibit responses to PD-1 or dual JAK2 and PD-1 treatment.
Adding JAK2 inhibitor Ruxolitinib to Pembrolizumab will have significant activity in patients with advanced, progressive HL who failed single agent PD-1 inhibition.

Inclusion criteria
-
advanced progressive MPNs, defined as intermediate and high risk MF or advanced PV resistant, failed or intolerant to JAK2 inhibitor therapy requiring medical therapy and patients with MDS/MPN Overlap and CMML having failed or for whom there are no standard therapies are available, are eligible. Patients will be allocated to one of two treatment arms:
- Pembrolizumab
- Pembrolizumab plus JAK2 inhibitor Ruxolitinib
-
Patients with relapsed* or refractory* Hodgkin lymphoma (HL) who progress on PD-1 inhibitory treatment after achieving a partial response (PR) or complete response (CR) or stable disease (SD) or who are non-responsive to PD-1 inhibitory therapy. Patients must have failed appropriate standard treatment options.
-
Relapsed: disease progression after most recent therapy
-
Refractory: failure to achieve CR or PR to most recent therapy
-

- Alkaline Phosphatase < 5 x ULN
- Serum creatinine ≤ 2 x ULN or 24 hour Cr clearance >60ml/min
- Hematological inclusion criteria for:

Female subject of childbearing potential should have a negative urine or serum pregnancy within 72 hours prior to receiving the first dose of study medication. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required.
