Enrollment: 17
Healthy volunteers: no

Brief summary:
This is a multicenter, single-arm, open label, study consisting of two cohorts. Cohort 2 explores the combination of copanlisib and pembrolizumab in patients with relapsed or refractory NKTCL, who have received at least 1 prior systemic therapy. Cohort 2 will include a phase 1 portion (cohort 2a) to determine the recommended phase 2 dose (RP2D) utilizing a standard 3+3 design, followed by a phase II portion where patients will be treated at the RP2D (cohort 2b). The primary endpoint for cohort 1 was progression-free survival; the primary endpoint for cohort 2a will be to determine RP2D for the combination therapy; and overall response rate at the end of 4 treatment cycles for cohort 2b. Patients will be assessed for response with PET CT or CT every 12 weeks using the revised Cheson criteria. Correlative endpoints will be exploratory and assess PD-1 expression on peripheral blood lymphocytes; peripheral blood T-cell and NK-cell functional assays; PD-1 and PD-L1 expression on tumor tissue; tumor infiltrating lymphocytes and gene expression panels using the nanostring technology as prognostic and predictive biomarkers, as well as monitoring of minimal residual disease via high-throughput sequencing of cell free tumor DNA, and exosome analysis.

Detailed description:
Patients with relapsed or refractory (RR) NK and T-cell Lymphoma (NKTCL), who have received at least 1 prior systemic therapy, were enrolled in cohort 1. The study design for cohort 1 was a single arm phase II 2-stage design, to explore monotherapy with the PD-1 antibody pembrolizumab (or MK-3475) given intravenously at a fixed dose of 200mg every 3 weeks for up to 36 cycles. Enrollment to this cohort has been completed.

Arms:
arm 1: MK-3475 given intravenously at a fixed dose of 200mg every 3 weeks for up to 36 cycles arm 2: MK-3475 is given intravenously at a fixed dose of 200mg every 3 weeks Copanlisib is given intravenously at RP2D determined from Phase I study

Interventions: intervention 1: MK-3475 intervention 2: Copanlisib

2.0 TRIAL DESIGN 
This is a multicenter, single-arm, open label, study consisting of two cohorts. Patients with relapsed or refractory (RR) NK and T-cell Lymphoma 
(NKTCL), who have received at least 1 prior systemic therapy, were enrolled in cohort 1. The study design for cohort 1 was a single arm phase II 2-
stage design, to explore monotherapy with the PD-1 antibody pembrolizumab (or MK-3475) given intravenously at a fixed dose of 200 mg every 3 
weeks for up to 36 cycles. Enrollment to this cohort has been completed. Cohort 2 explores the combination of copanlisib and pembrolizumab in 
patients with relapsed or refractory NKTCL, who have received at least 1 prior systemic therapy. Cohort 2 will include a phase 1 portion (cohort 2a) 
to determine the recommended phase 2 dose (RP2D) utilizing a standard 3+3 design, followed by a phase II portion where patients will be treated at 
the RP2D (cohort 2b). The primary endpoint for cohort 1 was progression-free survival; the primary endpoint for cohort 2a will be to determine RP2D 
for the combination therapy; and overall response rate at the end of 4 treatment cycles for cohort 2b. Patients will be assessed for response with 
PET CT or CT every 12 weeks using the revised Cheson criteria. Correlative endpoints will be exploratory and assess PD-1 expression on peripheral 
blood lymphocytes; peripheral blood T-cell and NK-cell functional assays; PD-1 and PD-L1 expression on tumor tissue; tumor infiltrating lymphocytes 
and gene expression panels using the nanostring technology as prognostic and predictive biomarkers, as well as monitoring of minimal residual 
disease via high-throughput sequencing of cell free tumor DNA.

4.0 BACKGROUND & RATIONALE 
4.1 
Background 
4.1.1 Pharmaceutical and Therapeutic Background 
The importance of intact immune surveillance in controlling outgrowth of neoplastic transformation has 
been known for decades.3 Accumulating evidence shows a correlation between tumor-infiltrating 
lymphocytes (TILs) in cancer tissue and favorable prognosis in various malignancies.4-8  In particular, the 
presence of CD8+ T-cells and the ratio of CD8+ effector T-cells / FoxP3+ regulatory T-cells seems to 
correlate with improved prognosis and long-term survival in many solid tumors. 
 
The PD-1 receptor-ligand interaction is a major pathway hijacked by tumors to suppress immune control.  
The normal function of PD-1, expressed on the cell surface of activated T-cells under healthy conditions, 
is to down-modulate unwanted or excessive immune responses, including autoimmune reactions.  PD-1 
(encoded by the gene Pdcd1) is an Ig superfamily member related to CD28 and CTLA-4, which has been 
shown to negatively regulate antigen receptor signaling upon engagement of its ligands (PD-L1 and/or 
PD-L2).9,10 The structure of murine PD-1 has been resolved.11  PD-1 and family members are type I 
transmembrane glycoproteins containing an Ig Variable-type (V-type) domain responsible for ligand 
binding and a cytoplasmic tail which is responsible for the binding of signaling molecules.  The 
cytoplasmic tail of PD-1 contains 2 tyrosine-based signaling motifs, an immunoreceptor tyrosine-based 
inhibition motif (ITIM) and an immunoreceptor tyrosine-based switch motif (ITSM).  Following T-cell 
stimulation, PD-1 recruits the tyrosine phosphatases SHP-1 and SHP-2 to the ITSM motif within its 
cytoplasmic tail, leading to the dephosphorylation of effector molecules such as CD3ζ, PKCθ and ZAP70, 
which are involved in the CD3 T-cell signaling cascade.9,12-14 The mechanism by which PD-1 down 
modulates T-cell responses is similar to, but distinct from that of CTLA-4, as both molecules regulate an 
overlapping set of signaling proteins.15,16 PD-1 was shown to be expressed on activated lymphocytes 
including peripheral CD4+ and CD8+ T-cells, B-cells, T regs and Natural Killer cells.17,18 Expression has also 
been shown during thymic development on CD4-CD8- (double negative) T-cells as well as subsets of 
macrophages and dendritic cells.19  The ligands for PD-1 (PD-L1 and PD-L2) are constitutively expressed 
or can be induced in a variety of cell types, including non-hematopoietic tissues as well as in various 
tumors.15,20-22 Both ligands are type I transmembrane receptors containing both IgV- and IgC-like 
domains in the extracellular region and contain short cytoplasmic regions with no known signaling 
motifs.  Binding of either PD-1 ligand to PD-1 inhibits T-cell activation triggered through the T-cell 
receptor.  PD-L1 is expressed at low levels on various non-hematopoietic tissues, most notably on 
vascular endothelium, whereas PD-L2 protein is only detectably expressed on antigen-presenting cells

found in lymphoid tissue or chronic inflammatory environments.  PD-L2 is thought to control immune T-
cell activation in lymphoid organs, whereas PD-L1 serves to dampen unwarranted T-cell function in 
peripheral tissues.15 Although healthy organs express little (if any) PD-L1, a variety of cancers were 
demonstrated to express abundant levels of this T-cell inhibitor.  PD-1 has been suggested to regulate 
tumor-specific T-cell expansion in subjects with melanoma (MEL).23 This suggests that the PD-1/PD-L1 
pathway plays a critical role in tumor immune evasion and should be considered as an attractive target 
for therapeutic intervention. 
 
Pembrolizumab (previously known as SCH 900475) is a potent and highly selective humanized 
monoclonal antibody (mAb) of the IgG4/kappa isotype designed to directly block the interaction 
between PD-1 and its ligands, PD-L1 and PD-L2.   
 
The phosphatidylinositol 3-kinase (PI3K)/AKT/mammalian target of rapamycin (mTOR) pathway is one 
of the prominent pathways that promote cellular survival and constitutively is activated in many types 
of cancers (11, 12). Class I PI3K is downstream of most cancer-associated tyrosine kinase growth factor 
receptors (such as epidermal growth factor receptor [EGFR]/ human epidermal growth factor receptor 
[HER], insulin-like growth factor 1 receptor [IGF-1R], platelet-derived growth factor receptor [PDGFR], 
vascular endothelial growth factor [VEGF], c-KIT or mesenchymal epithelial transition factor [Met]). 
 
Four of these PI3K isoforms (PI3Kα, PI3Kβ, PI3Kγ, and PI3Kδ) are categorized as class I enzymes because 
they can use phosphatidylinositol-4,5-bisphosphate (PI-4,5-P2) as a substrate to generate 
phosphatidylinositol-3,4,5-trisphosphate (PIP3). Elevated PIP3 in cellular membranes drives several 
hallmarks of the cancer phenotype: cell proliferation, survival, metabolic reprogramming, and migration. 
PI3Kα and β are ubiquitous; PI3Kγ and δ are expressed mostly in hematopoietic tissues.  
 
As expected from its pharmacological properties, copanlisib, a small molecule pan-class 1 PI3K inhibitor 
with predominant activity against PI3Kα and PI3K isoforms, demonstrated anti-tumor activity in pre-
clinical models characterized by activating genetic aberrations of the PI3K pathway. 
 
Copanlisib exhibits potent kinase inhibitory effect on all four isoforms with biochemical IC50 values of 
0.5 nM, 0.7 nM, 3.7 nM and 6.4 nM for PI3Kα, PI3Kδ, PI3Kβ and PI3K, respectively.  Copanlisib also 
potently regulates nuclear localization of the forkhead family members resulting in the induction of 
transcriptional programs that lead to rapid cell death by apoptosis.

Rationale 
4.2.1 Rationale for the Trial and Selected Subject Population 
The peripheral T-cell lymphomas (PTCL) are a diverse group of mature T-cell and natural killer (NK) cell 
neoplasms accounting for 10-15% of non-Hodgkin lymphoma (NHL) diagnoses in the United States.24-26

The number of diagnoses has increased nearly 3-fold over the past 2 decades.27 In the WHO 
classification, the diverse mature T-cell and NK-cell neoplasms are listed individually. The PTCL 
histologies include PTCL-NOS, angioimmunoblastic T-cell Lymphoma (AITL), anaplastic large cell 
lymphoma (ALC) ALK positive and negative (the 3 most common histologies in the US), as well as the less 
common extranodal NK/T-cell lymphoma, nasal type, enteropathy-associated T-cell lymphoma (EATL), 
hepatosplenic T-cell lymphoma, subcutaneous panniculitis-like T-cell lymphoma and adult T-cell 
leukemia/lymphoma (ATLL).28,29 Therapy for the PTCLs is largely based on aggressive B-cell lymphoma 
regimens. Outcomes though are generally worse when compared to B-cell NHL with 5-year survival rates 
of 35-43% and for the rarer PTCLs 22%-24%.30 A recent analysis showed that the median time from initial 
diagnosis to relapse or progression after primary therapy is only 6.7 months.31  
 
In the absence of hematopoietic stem cell transplantation (HSCT) treatment is usually palliative in the 
relapsed/refractory setting with a median overall survival (OS) and progression-free survival (PFS) after 
relapse or progression of only 5.5 and 3.1 months, respectively.31 Even with high-dose therapy followed 
by autologous stem cell transplantation for chemosensitive disease, survival is poor (PFS <12 months; 
OS <18 months).32 There is currently no accepted standard of care for the treatment of r/r PTCL. Multiple 
combination and single agent regimens have been studied with limited success. The two most recently 
FDA approved agents for this indication are pralatrexate and romidepsin based on an overall response 
rate (ORR) of 29% and 25%, respectively.33,34 Overall survival appears only marginally better in patients 
who receive chemotherapy at relapse (6.5 vs. 3.7 months, respectively)31 identifying an unmet need. 
 
PD-L1 expression has been demonstrated for a variety of B- and T-cell lymphomas, specifically for the 
PTCL subtypes ALC, ATLL and extranodal NK-T-cell NHL.35-37 PD-L1 is also highly expressed in malignant 
lymphocytes of patients with cutaneous T-cell lymphomas.38 Additionally, expression of PD-1 peripheral 
blood CD4+ and CD8+ lymphocytes is markedly elevated in patients with lymphomas, including T-cell 
NHL, especially at the time of relapse.39 These findings, in addition to the observation that reconstitution 
of an immune anti-lymphoma effect following allogeneic stem cell transplantation (“graft-versus-
lymphoma” effect) can result in durable remissions for patients with  PTCL,40,41 indicate the essential role 
of an effective immune response for lymphoma control.  
 
Whilst multiple trials exploring PD-1 blockade in hematological malignancies are ongoing, published data 
supports its safety and efficacy. A phase 1 trial by Berger et al demonstrated that PD-1 blockade is safe 
in patients with hematological malignancies, even after allogeneic stem cell transplantation.42 Since then 
two other larger phase 2 studies with the PD-1 antibody pidilizumab for patients with diffuse large B-cell 
lymphoma following ASCT and follicular lymphoma have shown that PD-1 blockade is not only safe, but 
also has promising efficacy in lymphomas.43,44 The same appears to be the case for PD-L1 and CTLA-4 
blockade.45,46 While “active” immunotherapy by immune checkpoint blockade might not be applicable 
to all subtypes of PTCL, an additional anti-lymphoma effect of PD-1 antibodies by “passive” immune 
mechanisms could be postulated for T-cell NHL with high PD-1 expression (e.g. AITL).47-49 For this 
subgroup of patients with high PD-1 expression, binding of the PD-1 monoclonal antibody (mAb) could 
lead to direct cytotoxicity, although with an IgG4 mAbs such as pembrolizumab less antibody-dependent 
(ADCC) or complement mediated cytotoxicity is expected than with IgG1 mAbs.50 
 
In conclusion, strong preliminary evidence warrants the exploration of the PD-1 antibody 
pembrolizumab in patients with r/r PTCL.

4.2.2 Rationale for Dose Selection/Regimen/Modification (cohort 1) 
The choice of the 200 mg every 3 weeks (Q3W) as an appropriate dose for fixed dosing is based on 
simulations performed using the population PK model of pembrolizumab showing that the fixed dose of 
200 mg every 3 weeks will provide exposures that 1) are optimally consistent with those obtained with 
the 2 mg/kg dose every 3 weeks, 2) will maintain individual patient exposures in the exposure range 
established in melanoma as associated with maximal efficacy response and 3) will maintain individual 
patients exposure in the exposure range established in melanoma that are well tolerated and safe.  
 
A fixed dose regimen will simplify the dosing regimen to be more convenient for physicians and to reduce 
potential for dosing errors.  A fixed dosing scheme will also reduce complexity in the logistical chain at 
treatment facilities and reduce wastage. 
 
The rationale for the dose of 2 mg/kg and comparable doses of pembrolizumab Q3W is based on: 1) 
similar efficacy and safety of pembrolizumab when dosed at either 2 mg/kg or 10 mg/kg Q3W in 
melanoma patients, 2) the flat exposure-response relationships of pembrolizumab for both efficacy and 
safety in the dose ranges of 2 mg/kg Q3W to 10 mg/kg Q3W, 3) the lack of effect of tumor burden or 
indication on distribution behavior of pembrolizumab (as assessed by the population PK model) and 4) 
the assumption that the dynamics of pembrolizumab target engagement will not vary meaningfully with 
tumor type. 
 
4.2.3 Rationale for pembrolizumab and copanlisib combination treatment (cohort 2) 
Enrollment to cohort 1, where patients with RR NKTCL were enrolled and treated with single agent 
pembrolizumab, has been completed. Out of 18 enrolled patients, all patients were evaluable for toxicity 
and 15 were evaluable for response.  Four patients achieved a complete response, and 1 patient 
achieved partial response resulting in a 27% complete response (CR) rate (95% CI 5%-49%) and overall 
response rate (ORR) of 33% (95% CI 9-55%). Remissions were durable with 2 patients remaining on study 
(1 patient >12 months, 1 patient >10 months) as of February 2018. Only 3 came off study for toxicity 
(17%, 95% CI 0%-34%; pneumonitis n=1; vasculitis, n=1; hyperbilirubinemia, n=1). However, although 
the response rate with single agent pembrolizumab is comparable to other approved agents in this 
setting, as only 5 pts had not progressed by 3 months, the futility endpoint was not met and enrollment 
to cohort 1 was halted early for futility as per original statistical design.  
 
Copanlisib similarly demonstrated single agent activity in T-cell NHL with an overall response rate of 
21%.52  
 
While both agents alone have moderate activity, there is preclinical evidence that supports synergy 
between PD1-inhibitors and PI3K inhibitors. Inhibition of PI3Kβ, PI3Kγ, and PI3Kδ enhances antitumor 
immunity and susceptibility to immune checkpoint inhibitors and can potentially overcome resistance 
to either drug alone.53-57 furthermore, inhibition of the PI3K pathway may abrogate a possible disease 
flare with PD-1/PDL-1 blockade in NKTCL.58  
 
We hypothesize that the combination of the PD1-inhibitor pembrolizumab with the copanlisib will be 
safe and result in synergistic efficacy in the treatment of mature NK/T-cell NHL. Therefore, Cohort 2 has 
been added to the original study to explore the combination treatment

4.2.3.1 Study design for cohort 2  
As the recommended phase II dose of Copanlisib in combination with pembrolizumab (MK-3475) has not 
been established, there will be a phase 1 part (cohort 2a), during which the recommended phase 2 dose 
(RPTD) of the combination of pembrolizumab and copanlisib will be determined. This will be followed by 
a phase 2 portion (cohort 2b), which will explore safety and efficacy of the combination. The phase 1 
part follows a classical ‘3+3’ dose escalation/de-escalation design with up to 3 dose levels (-1, 0, and 1). 
Based on preclinical data, the copanlisib dose and dosing frequency will change with dose levels (dose 
level -1: 45 mg on day 1 q21d; dose level 0: 45 mg days 1 & 8 q21d; dose level 1: 60 mg days 1 & 8 q21d), 
while the pembrolizumab dose will remain a flat dose of 200 mg on day 1 of every 21 day cycle for each 
dose level. In the initial cohort up to 3 patients will be treated on dose level 0. Should less than 1 patient 
experience a dose-limiting toxicity (DLT) during cycle 1, then the next 3 patients will be treated at dose 
level 1.  However, should 1 out of 3 of the initial patients treated on dose level 0 experiences a DLT, 3 
more patients will be enrolled on the same dose level.  Should no further patient experience a DLT, we 
will proceed to dose level 1, where 3 patients will be treated. If 0 out of 3 experience a DLT, 3 more 
patients will be added.  However, should at any time 2 patients on dose level 0 experience a DLT, the 
dose will be de-escalated to dose level -1, where up to 6 patients will be treated.  If 2 or more patients 
on dose level -1 experience a DLT, the trial will be terminated.  The highest dose level, at which ≤1/6 
patients experience a DLT will be defined as the RP2D.

Maximum Tolerated Dose: The maximum tolerated dose (MTD) is defined as the highest dose tested in 
which none or only one patient experienced DLT attributable to the study drug(s), when 6 patients have 
been treated at that dose and are evaluable for toxicity.  
 
Recommended Phase II dose (RP2D): MTD will be considered as the RP2D, unless there are other safety 
concerns. 
 
4.2.3.2 DLT definition 
DLT window for the phase I portion of this study is 21 days or 1 cycle.  
 
DLT will be defined as any of the below AE occurring during cycle 1 that are considered by the 
investigator as at least possibly related to study treatment with copanlisib and pembrolizumab: 
- 
CTCAE grade 4 neutropenia lasting > 7 days despite growth factor support 
- 
CTCAE grade 4 febrile neutropenia  
- 
CTCAE grade 3 thrombocytopenia with bleeding that requires transfusion therapy

- 
Treatment delays by treatment-related toxicity causing > 14 days in the start of a subsequent 
cycle of treatment  
- 
Non-hematologic toxicities of CTCAE ≥ grade 3 except for the following: 
o Alopecia of any grade 
o CTCAE grade 3 fatigue for < 72 hours,  
o Isolated, asymptomatic grade 3 changes in biochemistry laboratory values that last for ≤ 
7 days. This includes electrolyte abnormalities that respond to medical intervention. 
Exceptions are Bilirubin elevation ≥ CTCAE grade 3; and Bilirubin ≥ grade 2 with ALT ≥ 
CTCAE grade 3 – those count as DLT. 
o ≥ CTCAE grade 3 vomiting or nausea that can be controlled (i.e. <grade 3) within 72h 
with optimal anti-emetic treatment 
o ≥ CTCAE grade 3 diarrhea that can be controlled within 72h (i.e. <grade 3) with the use 
of optimal anti-diarrheal treatment 
o ≥ CTCAE grade 3 hypothyroidism/hyperthyroidism 
o ≥ CTCAE grade 3 hyperglycemia that resolves within 7 days 
o CTCAE grade 3 arthralgias/myalgias that resolve within 7 days with the use of anti-
inflammatory drugs 
o CTCAE grade 3 infusion reactions that resolve within 6 hours with appropriate 
management in the absence of steroid and antihistamine prophylactic premedication 
 
AEs occurring in the “induction phase” of copanlisib only treatment (i.e. days -1 to day -21 of the 
induction phase) will not be considered a DLT in terms of determining the RPTD. Treatment-related 
AE ≥ CTCAE grade 3 or grade 2 treatment-related AE that lead to dose interruption of >6 weeks and 
that occur after cycle 1 may be considered a DLT after discussion with the sponsor/study chair. 
Patients who come off during the induction phase for any reason will be replaced.  
 
4.2.3.3 Phase II portion of Cohort 2 
We will enroll up to 18 patients treated at the RPTD in the phase II portion in order to define safety and 
feasibility of the combination of pembrolizumab and copanlisib (total of 24 patients treated at the RPTD 
in the phase I and II portions combined). Furthermore, there will be a “induction phase” treatment with 
2 weekly doses of copanlisib (days -21 and -14) starting 3 weeks prior to day 1 of cycle 1 in order to 
assess potential copanlisib induced changes in peripheral blood immune cell biomarkers. Patients who 
come off during the induction phase for any reason will be replaced and not included in the futility 
analysis.  
 
4.2.4 Rationale for Endpoints 
4.2.4.1 Efficacy Endpoints 
The objective of this trial is to explore the safety and efficacy of pembrolizumab in patients with NKTCL 
(Cohort 1). We will assess efficacy by evaluating progression-free survival (PFS), overall survival (OS) and 
response rate. For cohort 2 the objective is to determine RP2D in phase I portion of the study and then 
to determine objective response rate using the combination therapy in phase II portion. Classical

Version Date 01/13/2020 
response criteria such as defined by the RECIST,59 the revised Cheson criteria1 or the Lugano criteria2 
may not capture responses seen with immunotherapeutic agents. Therefore, we had chosen PFS as 
primary endpoint rather than response rate in Cohort 1. However, from our experience in cohort 1, all 
patients who remained progression free at 3 months had at least stable disease, and durable responses 
were only seen in patients with at least a partial response on their first response assessment. Therefore, 
response and not PFS was chosen as primary outcome and efficacy of the combination therapy in cohort 
2 will be determined by response as measured by objective response rate defined as complete or partial 
responses. 
 
Measurement of effect is described in Section 14.3 of the Appendix. While we will use the revised Cheson 
criteria to assess disease response, we will allow at the first imaging time point (12 weeks after initiating 
treatment) patients to demonstrate up to 2 new lesions, with sum of all lesions <70% greater than 
baseline by sum of products of the diameters (SPD), or decreasing in size, if they are clinically stable 
without evidence of rapid clinical deterioration. In that case patients may continue to be treated with 
pembrolizumab and clinically observed with imaging repeated after 1 month. If, at that time, there is 
Progression of Disease (POD) by standard Revised Cheson Response Criteria, patients will be removed 
from study. For a more detailed description see Appendix – Section 14.3.5 Response Endpoints. 
 
4.2.4.2 Biomarker Research 
4.2.4.2.1 
PD-1, PD-L1 and tumor infiltrating lymphocytes (TIL)  
We will assess expression of PD-1, PD-L1 and tumor infiltrating lymphocytes (TIL) in pre-treatment tumor 
specimens in order to assess their ability to predict response to pembrolizumab therapy and serve as a 
potential prognostic or predictive biomarker. Multiple studies have implicating expression of PD-1, PD-
L1, in the tumor or tumor microenvironment as well as presence of TIL be associated with outcomes.60-
63 
 
4.2.4.2.2 
Immune cell biomarkers 
Additionally, we will assess PD-1 expression and leukocyte activation markers on circulating lymphocytes 
as well as NK- and T-cell function pre-treatment, during treatment as well as at time of relapse in order 
to assess potential associations with treatment response and outcome. In addition, we will also assess 
PD-L1 and PD-L2 on the surface of peripheral tumor cells when detectable. Preliminary studies of 
immune cell biomarkers, including PD-1, on peripheral blood mononuclear cells in renal cell carcinoma 
by our group have indicated that PD-1 expression on fresh peripheral blood leukocytes may provide a 
useful marker for disease progression. Furthermore, the results suggest that measuring PD-1 levels in 
peripheral blood may assist in identifying patients likely to respond to PD-1 blocking antibodies.64 
 
4.2.4.2.3 
Non-invasive disease monitoring 
High-throughput sequencing (HTS) is an emerging technology enabling quantitative measurement of 
cell-free DNA in peripheral blood.65,66 It is highly sensitive and has been shown to assist with non-invasive 
monitoring of disease status in diffuse large B cell lymphoma66,67 and follicular lymphoma.68 Not only is 
this technology non-invasive, but it provides an opportunity for earlier detection of relapse than 
traditional imaging techniques.67 HTS of the T-cell receptor (TCR) has been utilized for disease monitoring 
in other hematologic malignancies including cutaneous T cell lymphoma,69 acute lymphoblastic

leukemia,70 and chronic lymphocytic leukemia.65 HTS can be used to identify clonal evolution68 as well 
as early disease relapse, which has been shown to predict survival70 and may inform therapeutic 
intervention.65,71 This technology has not yet been studied in peripheral T-cell lymphoma, signifying an 
unmet need for investigation. 
 
 
We will utilize HTS commercialized by ImmunoSEQTM to measure pre-treatment levels of 
circulating cell free DNA as well as at pre-determined intervals during treatment. We will investigate the 
relationship between pre-treatment level with PFS and OS. In addition, we will examine the association 
of circulating cell free DNA levels during treatment with disease response to therapy.  
 
 
Genomic DNA from PBMC will be collected and stored for possible future research. 
 
4.2.4.2.4 
Exploration of predictive biomarkers using gene expression profiling via 
Nanostring technology 
 In order to explore biomarkers predictive of response to pembrolizumab we will perform gene 
expression profiling via Nanostring technology using the nCounter® PanCancer Immune Profiling Panel 
as well as the nCounter® PanCancer Pathway Panel on tumor tissue. This will allow us to better 
characterize a) the immune milieu of the tumor microenvironment and b) deregulated pathways in PTCL. 
 
We hypothesize that patterns of differential gene expression as described by the above panels will 
provide gene signatures predictive of response to pembrolizumab.  
 
Additionally, we will design a nanostring gene expression panel composed of up to 30 genes of interest 
in PTCL based on the available literature and preliminary work performed by researchers at the Fox 
Chase Cancer Center. Examples include DLX5, a gene encoding a transcription factor, which is up 
regulated in up to 40% of T cell lymphoid malignancies and associated with aggressive behavior.72,73 
Others include Rpl22, a ribosomal protein gene, and Lin28b, a gene encoding a “stemness” factor and 
others to be potentially involved in T-cell lymphomagenesis and prognosis.74-77  
 
We hypothesize that above analysis can potentially identify additional pathways whose roles in 
pathogenesis or disease progression have previously not been recognized or well described.  
 
4.2.4.2.5 
Identification of copanlisib induced changes in peripheral blood immune cell 
biomarkers 
We will assess the copanlisib induced changes in the immune cell biomarkers. For this the patients will 
be treated with copanlisib alone at day -21 and -14 during the induction phase prior to cycle 1 day 1. The 
blood sample will be collected before drug administration (day -21) and day -7 during the induction 
phase and then for research on cycle 1 day 1 prior to drug administration. The copanlisib induced 
changes in immune biomarkers will also be correlated to the clinical outcome to identify biomarkers of 
response to clinical outcome.

transplant are allowed as long as they have no evidence of active GVHD or are not taking 
immunosuppressive therapy  
19. Uncontrolled arterial hypertension despite optimal medical management 
20. Uncontrolled Type I or II diabetes mellitus as deemed appropriate by the investigator. Suggested 
guidelines for uncontrolled diabetes: HbA1c > 8.5% 
21. Anti-arrhythmic therapy (beta blockers or digoxin are permitted) 
22. Use of CYP3A4 inhibitors and inducers. Copanlisib is primarily metabolized by CYP3A4. Therefore, 
concomitant use of strong inhibitors of CYP3A4 (e.g., ketoconazole, itraconazole, clarithromycin, 
ritonavir, indinavir, nelfinavir and saquinavir), and strong inducers of CYP3A (e.g. rifampin, 
phenytoin, carbamazepine, phenobarbital, St. John’s Wort) are not permitted from Day -14 of 
Cycle 1 until the Safety follow up visit. See Table in Appendix 5 for complete list  
23. Concurrent diagnosis of pheochromocytoma 
24. Arterial or venous thrombotic or embolic events such as cerebrovascular accident (including 
transient ischemic attacks), deep vein thrombosis or pulmonary embolism within 3 months 
before the start of study medication 
25. Prior exposure to PI3K inhibitors, unless on PI3K inhibitor therapy more than 6 months ago AND 
reason for discontinuation of prior PI3K inhibitor therapy was other than progression or toxicity. 
26. Patients with detectable CMV viremia are excluded

Trial treatment should begin within 7 days of the date on which treatment is assigned. Cohort 2 will have 
a 21 day long induction phase prior to the beginning of treatment (numbered day -1 to -21, followed 
immediately by Cycle 1 Day 1) cycles during which subjects will receive 2 doses of copanlisib alone, first 
one on day -21 and second dose on day -14 of the induction phase. 
 
During treatment cycles, on the days both pembrolizumab and copanlisib are administered, copanlisib 
must be administered first, followed by pembrolizumab. 
 
5.2.1 Dose Selection/Modification 
The attribution of causality of any AE to the test drugs specifically may be difficult. However, in Phase I 
and II trials, certain toxicities were seen only in relation to copanlisib, e.g., transient increases in glucose 
and blood pressure. If a particular AE is attributed to pembrolizumab or copanlisib then the specific drug 
can be interrupted according to the dose modification criteria while the other may continue. Both drugs 
may need to be interrupted if attribution is not clear. If toxicity is not resolved such that the drug/s 
cannot be administered 21 days beyond their scheduled administration the patient will be off treatment. 
If the toxicity that results in treatment discontinuation is clearly due to one of the drugs, then the patient 
can be treated on monotherapy after discussion with the sponsor-investigator. Dosing interruptions are 
permitted in the case of medical / surgical events or logistical reasons not related to study therapy (e.g., 
elective surgery, unrelated medical events, patient vacation, and/or holidays). Subjects should be placed 
back on study therapy within 3 weeks of the scheduled interruption, unless otherwise discussed with 
the Sponsor. The reason for interruption should be documented in the patient's study record. 
 
5.2.1.1 Dose Selection 
The rationale for selection of doses to be used in this trial is provided in Section 4.0 – Background and 
Rationale.   
 
The dose amount required to prepare the pembrolizumab and copanlisib infusion solution will be a fixed 
dose (i.e. not dependent upon patient’s weight).   
 
5.2.1.2 Pembrolizumab (MK-3475) and copanlisib Dose Modification 
(Escalation/Titration/Other) for immune-related events 
Adverse events (both non-serious and serious) associated with pembrolizumab and/or copanlisib 
exposure may represent an immunologic etiology.  These adverse events may occur shortly after the 
first dose or several months after the last dose of treatment. Pembrolizumab must be withheld for drug-
related toxicities and severe or life-threatening immune-related AEs as per Table 3 below. For guidelines 
on the management of adverse events with potential immunological etiology see Section 5.4 Supportive 
Care and Management of Immune-related Adverse Events, including use of corticosteroids.

5.2.1.3 Copanlisib Dose Modifications 
Treatment interruptions for copanlisib must be done according to the guidelines in hematological 
toxicity and non-hematological toxicity sections (5.2.1.3.1 and 5.2.1.3.2) except for immune related 
adverse events, in which case, instruction from section 5.2.1.2 and Table 3 should be followed. The 
investigator may judge a more conservative dose modification if appropriate. If dose reduction below 
30mg is required, the patient has the option of continuing on pembrolizumab alone.  Furthermore, if 
copanlisib is discontinued due to non-immune-related toxicities or toxicities clearly related to copanlisib

Arterial Hypertension 
No dose should be given if blood pressure is ≥ 150/90 mmHg. Antihypertensive medication may be given 
to control the increased blood pressure. Dosing can proceed on the scheduled day if there are at least 2 
consecutive measurements <150/90 mmHg apart. Otherwise dosing must be delayed.  
 
If drug-related arterial hypertension (post-dose blood pressure of CTCAE Grade 3 or  160/100 mmHg) 
is not manageable with optimal antihypertensive treatment, the dose for the subsequent copanlisib 
administrations may be reduced by 1 or 2 dose levels at the investigator’s discretion. Patients with a 
post-dose blood pressure that may have life-threatening consequences (e.g. malignant arterial 
hypertension, transient or permanent neurologic deficit, hypertensive crisis) must permanently 
discontinue copanlisib.

Patients who develop infusion related hyperglycemia > 250 mg/dL (13.9 mmol/L) after study drug 
administration may continue treatment. However, the next infusion must be delayed until the patient’s 
pre-infusion glucose levels return to < 160 mg/dL (8.9 mmol/L) (fasting) or < 200 mg/dL (11.1 mmol/L) 
(non-fasting). 
Persistent infusion related hyperglycemia > 200 mg/dL (11.1 mmol/L) based on repeated laboratory 
analysis despite glucose lowering therapy after 2 infusions of study drug will require dose reduction by 
one dose level. Further dose reduction (where appropriate per study design/population) is allowed as 
long as discontinuation criteria was not met. 
 
5.2.1.3.5 
Management of hyperlipidemia 
As lipids are monitored for the duration of this study it is recommended to treat significant deviations 
from normal range with standard interventions and therapy in standard doses according to local medical

practice. Goals of therapy are to keep fasting triglycerides < 300 mg/dL (3.4 mmol/L) and low-density 
lipoproteins (LDL) < 190 mg/dL (4.9 mmol/L) (lower LDL depending on cardiovascular risk) in patients 
with a life expectancy >1 year. The goals for fasting triglycerides can be raised to < 500 mg/dL (5.6 
mmol/L) for patients with life expectancy <1 year. Although there is a paucity of data on the effects of 
hyperlipidemia and cancer outcomes, these goals have been chosen to decrease risk of established 
complications of hypertriglyceridemia (pancreatitis) and hypercholesterolemia (cardiovascular events). 
For evaluation of lipid panels including triglycerides the patient would be required to be fasted for 11 
hours prior to sampling. For patients who cannot adhere to these fasting requirements the evaluation 
of lipid panels including triglycerides and determination of treatment is considered as not feasible. 
 
5.2.2 Dose Administration 
5.2.2.1 Pembrolizumab  
Pembrolizumab should be administered on Day 1 of each cycle after all procedures/assessments have 
been completed as detailed on the Trial Flow Chart (Section 6.0).  Trial treatment may be administered 
up to 3 days before or after the scheduled Day 1 of each cycle due to administrative reasons. 
 
All trial treatments will be administered on an outpatient basis. 
 
Pembrolizumab will be administered as a 30 minute IV infusion (treatment cycle intervals may be 
increased due to toxicity as described in Section 5.2.1.2).  Sites should make every effort to target 
infusion timing to be as close to 30 minutes as possible.  However, given the variability of infusion pumps 
from site to site, a window of -5 minutes and +10 minutes is permitted (i.e., infusion time is 30 minutes: 
-5 min/+10 min). 
 
The following infusion set materials are compatible with pembrolizumab (MK-3475): 
•      PVC Infusion set that is plasticized using DEHP 
•      PVC and tri-(2-ethylhexyl) trimellitate (TOTM) infusion set 
•      Polyethylene lined PVC infusion set 
•      PVC Infusion set that is plasticized using Di-2-ethylhexyl Terephthalate (DEHT) 
•      Polyurethane set. 
 
 A sterile, non-pyrogenic, low-protein binding 0.2 to 5 µm in-line filter made of polyethersulfone (PES) 
must be used during administration to remove any adventitious particles.  If the infusion set does not 
contain 0.2 to 5 µm in-line filter, it is recommended to use 0.2 to 5 µm add-on filter which may contain 
an extension line. 
 
Attach the infusion line to the pump and prime the line, either with normal saline (at least 25 mL) or with 
infusion solution as per local SOP, before starting the infusion. 
 
Infuse pembrolizumab (MK-3475) over approximately 30 minutes, with a window of -5 and +10 minutes, 
through a peripheral line or indwelling catheter. 
 
Ensure the entire contents of the bag are dosed and all remaining drug solution in the line is administered 
according to institutional guidelines for saline flushing.

Document volume administered according to data entry guidelines. 
 
Vital signs will be monitored every 15 minutes during the infusion and for 60 minutes after completion 
of each infusion.  
 
Whenever possible, the lowest infusion rate should be used that will allow completion of the infusion 
within the 30 minutes. Maximum rate of infusion should not exceed 6.7 mL/min. through a peripheral 
line or indwelling catheter. However, when it is necessary to infuse a larger volume (i.e. 250 mL), the 
flow rate may go as high as 10 mL/min (maximum) in order to keep the infusion within the window as 
defined above. 
 
5.2.2.2 Copanlisib  
Before commencing copanlisib, all patients should have CMV status assessed. CMV seronegative patients 
should receive CMV-negative or filtered blood products. For seropositive patients, CMV quantitative 
polymerase chain reaction (PCR) testing with every cycle is recommended. Interrupt Copanlisib in 
patients with evidence of active CMV infection of any grade or viremia until the viremia has resolved. 
Ganciclovir or valganciclovir should be preemptively initiated in patients with positive CMV PCR and 
symptoms consistent with CMV infection, patients presenting with fever and no clear source in whom 
quantitative CMV testing is unavailable, and asymptomatic patients with increasing viral load. 
 
Copanlisib should be administered on Day 1 +/- Day 8 of each cycle after all procedures/assessments 
have been completed as detailed on the Trial Flow Chart (Section 6.0). Day 1 drug administration has a 
window of +/- 3 days. Copanlisib is supplied as lyophilized preparation in a 6-mL injection vial. The total 
amount of copanlisib per vial is 60 mg. The solution for IV infusion is obtained after reconstitution of the 
lyophilisate with 0.9% sodium chloride solution. 
 
Study drug is administered in a normal saline solution, intravenously, over 1 hr. No intravenous glucose 
preparations should be administered on the days of infusion. 
Induction phase:   
Fasting is required (8 hours minimum) only during the induction phase visits before the first glucose 
measurement on date of infusion. A low glycemic index meal may be taken 2 hours post-infusion unless 
the patient needs to have a low glycemic meal and unable to fast for this period of time, then glucose 
test should be taken prior to meal intake. 
It is imperative that the induction phase visits fall on Mon-Thurs during the week so that there is enough 
time to ship the blood collected for correlative studies to Fox Chase Cancer Center to be processed within 
the required window (blood may not be processed during the weekend). Also, blood collection must be 
scheduled so that it reaches Fox Chase Cancer Center on a working day, and not on a holiday.  
All subsequent infusions after Induction phase: 
The decision regarding meal timing can be made by the investigator based on glucose response patterns 
during prior treatment days.

NOTE: If patient needs to have a low glycemic meal prior to the infusion, then glucose test should be 
taken prior to the meal and/or at 1-2 hours after the meal.  
 
After the induction phase, a low glycemic index meal may be taken at least 4 h before the start of the 
study drug infusion for patients who have their infusions scheduled at a later treatment time or due to

A blood count will be performed and assessed prior to study drug infusion on Day 8 of each cycle. On 
day 8 the dose of copanlisib will be administered if, on the day of scheduled dosing, the laboratory test 
criteria for hemoglobin, ANC and platelets are met. 
 
Blood pressure measurement on treatment days 
Blood pressure will be measured every 5 – 10 minutes prior to each copanlisib dose (no more than 4 
measurements) until there are two consecutive results < 150/90 mmHg. If blood pressure is ≥ 150/90 
mmHg, the investigator can consider a medical intervention or delaying the infusion of study drug. The 
patient should rest for 5-10 minutes before blood pressure is recorded. 
On infusion days, blood pressure will be measured at 0 h (pre-dose), 30 min (mid-infusion), 60 min (end 
of infusion), and 1 h and 2 hours after the end of infusion  
Note: a window of ±10 min is allowed for all BP measurements, except for the 0 h (pre-dose) 
measurement 
 
5.2.3 Participant Registration

The investigator should discuss any questions regarding this with the Sponsor.  The final decision on any 
supportive therapy or vaccination rests with the investigator and/or the subject's primary physician.  
However, the decision to continue the subject on trial therapy or vaccination schedule requires the 
mutual agreement of the Investigator, the Sponsor, and the subject. Ganciclovir or valganciclovir should 
be preemptively initiated in patients with positive CMV PCR and symptoms consistent with CMV 
infection, patients presenting with fever and no clear source in whom quantitative CMV testing is 
unavailable, and asymptomatic patients with increasing viral load. 
 
Bactrim Prophylaxis:  Bactrim DS 1 tablet three times weekly, or 1 SS tablet daily, or equivalent (if sulfa 
allergic) for PJP prophylaxis will be administered to the patients. 
 
5.3.1 Acceptable Concomitant Medications 
All treatments that the investigator considers necessary for a subject’s welfare may be administered at 
the discretion of the investigator in keeping with the community standards of medical care.  All 
concomitant medication will be recorded on the case report form (CRF) including all prescription, over-
the-counter (OTC), herbal supplements, and IV medications and fluids.  If changes occur during the trial 
period, documentation of drug dosage, frequency, route, and date may also be included on the CRF. 
All concomitant medications received within 28 days before the first dose of trial treatment and 30 days 
after the last dose of trial treatment must be recorded.  Concomitant medications administered after 30 
days after the last dose of trial treatment must be recorded for SAEs and ECIs as defined in Sections 8.2 
and 8.3. Growth factors and blood product transfusions are allowed at the investigator’s discretion in 
order to maintain adequate blood counts in patients with documented bone marrow involvement.  
 
5.3.2 Prohibited Concomitant Medications 
Subjects are prohibited from receiving the following therapies during the Screening and Treatment Phase 
(including retreatment for post-complete response relapse) of this trial: 
 Anti-cancer systemic chemotherapy or biological therapy  
 Immunotherapy not specified in this protocol 
 Chemotherapy not specified in this protocol 
 Investigational agents other than pembrolizumab or copanlisib 
 Radiation therapy  
o Note:  Radiation therapy to a symptomatic solitary lesion or to the brain may be allowed 
after consultation with Sponsor.   
 Live vaccines within 30 days prior to the first dose of trial treatment and while participating in 
the trial.  Examples of live vaccines include, but are not limited to, the following: measles, mumps, 
rubella, chicken pox, yellow fever, rabies, BCG, and typhoid (oral) vaccine. Seasonal influenza 
vaccines for injection are generally killed virus vaccines and are allowed; however intranasal 
influenza vaccines (e.g. Flu-Mist®) are live attenuated vaccines, and are not allowed.  
 Glucocorticoids for any purpose other than to modulate symptoms from an event of clinical 
interest of suspected immunologic etiology or acute medical reasons (e.g. asthma exacerbation), 
but not solely as an anti-tumor therapy.  The use of physiologic doses of corticosteroids may be

approved after consultation with the Sponsor. Patients may be using topical or inhaled 
corticosteroids. The use of corticosteroids as antiemetics prior to copanlisib administration will 
not be allowed 
 Strong inhibitors or inducers of CYP3A4/5 (see appendix 5) 
 Substrates of CYP3A4/5 with narrow therapeutic index 
 Medications that carry a strong risk for QT prolongation 
 Herbal medications/preparations (except for vitamins) 
 
Subjects who, in the assessment by the investigator, require the use of any of the aforementioned 
treatments for clinical management should be removed from the trial.  Subjects may receive other 
medications that the investigator deems to be medically necessary. 
The Exclusion Criteria describes other medications which are prohibited in this trial. 
There are no prohibited therapies during the Post-Treatment Follow-up Phase. 
 
5.4 Supportive Care and Management of Immune-related Adverse Events 
Subjects should receive appropriate supportive care measures as deemed necessary by the treating 
investigator.  Suggested supportive care measures for the management of adverse events with potential 
immunologic etiology are outlined below. Where appropriate, these guidelines include the use of oral 
or intravenous treatment with corticosteroids as well as additional anti-inflammatory agents if 
symptoms do not improve with administration of corticosteroids.   Note that several courses of steroid 
tapering may be necessary as symptoms may worsen when the steroid dose is decreased. For each 
disorder, attempts should be made to rule out other causes such as metastatic disease or bacterial or 
viral infection, which might require additional supportive care. The treatment guidelines are intended to 
be applied when the investigator determines the events to be related to pembrolizumab.  
 
Note: if after the evaluation the event is determined not to be related, the investigator is instructed to 
follow the ECI reporting guidance but does not need to follow the treatment guidance (as outlined in the 
ECI guidance document). Refer to Section 5.2.1.2 for dose modification.  
 
It may be necessary to perform conditional procedures such as bronchoscopy, endoscopy, or skin 
photography as part of evaluation of the event. 
 
 Pneumonitis:  
o For Grade 2 events, treat with systemic corticosteroids (initial dose of 1-2 mg/kg 
prednisone or equivalent). When symptoms improve to Grade 1 or less, steroid taper 
should be started and continued over no less than 4 weeks. 
o For Grade 3-4 events, immediately treat with intravenous steroids.  Administer 
additional anti-inflammatory measures, as needed. 
o Add prophylactic antibiotics for opportunistic infections in the case of prolonged steroid 
administration. 
 Diarrhea/Colitis:

Version Date 01/13/2020 
Subjects should be carefully monitored for signs and symptoms of enterocolitis (such as diarrhea, 
abdominal pain, blood or mucus in stool, with or without fever) and of bowel perforation (such 
as peritoneal signs and ileus).   
 
o All subjects who experience diarrhea/colitis should be advised to drink liberal quantities 
of clear fluids.  If sufficient oral fluid intake is not feasible, fluid and electrolytes should be 
substituted via IV infusion.  For Grade 2 or higher diarrhea, consider GI consultation and 
endoscopy to confirm or rule out colitis. 
o For Grade 2 diarrhea/colitis that persists greater than 3 days, administer oral 
corticosteroids.  
o For Grade 3 or 4 diarrhea/colitis that persists > 1 week, treat with intravenous steroids 
followed by high dose oral steroids.   
o When symptoms improve to Grade 1 or less, steroid taper should be started and 
continued over no less than 4 weeks. 
 
 Type 1 diabetes mellitus (if new onset, including diabetic ketoacidosis [DKA]) or ≥ Grade 3 
Hyperglycemia, if associated with ketosis (ketonuria) or metabolic acidosis (DKA) 
 
o For T1DM or Grade 3-4 Hyperglycemia 
 Insulin replacement therapy is recommended for Type I diabetes mellitus and for 
Grade 3-4 hyperglycemia.  
 Evaluate patients with serum glucose and a metabolic panel, urine ketones, 
glycosylated hemoglobin, and C-peptide.  
 Administer anti-hyperglycemic in participants with hyperglycemia. 
 
 Hypophysitis: 
 
o For Grade 2 events, treat with corticosteroids. When symptoms improve to Grade 1 or 
less, steroid taper should be started and continued over no less than 4 weeks. 
Replacement of appropriate hormones may be required as the steroid dose is tapered. 
o For Grade 3-4 events, treat with an initial dose of IV corticosteroids followed by oral 
corticosteroids. When symptoms improve to Grade 1 or less, steroid taper should be 
started and continued over no less than 4 weeks. Replacement of appropriate hormones 
may be required as the steroid dose is tapered. 
 
 Hyperthyroidism or Hypothyroidism:  
Thyroid disorders can occur at any time during treatment. Monitor patients for changes in thyroid 
function (at the start of treatment, periodically during treatment, and as indicated based on 
clinical evaluation) and for clinical signs and symptoms of thyroid disorders. 
 
o Grade 2 hyperthyroidism events (and Grade 2-4 hypothyroidism): 
 In hyperthyroidism, non-selective beta-blockers (e.g. propranolol) are suggested 
as initial therapy. 
 In hypothyroidism, thyroid hormone replacement therapy, with levothyroxine or 
liothyroinine, is indicated per standard of care.

o Grade 3-4 hyperthyroidism  
 Treat with an initial dose of IV corticosteroid followed by oral corticosteroids. 
When symptoms improve to Grade 1 or less, steroid taper should be started and 
continued over no less than 4 weeks. Replacement of appropriate hormones may 
be required as the steroid dose is tapered. 
 
 Hepatic: 
o For Grade 2 events, monitor liver function tests more frequently until returned to 
baseline values (consider weekly). 
 Treat with IV or oral corticosteroids (initial dose of 0.5-1 mg/kg prednisone or 
equivalent) followed by taper 
o For Grade 3-4 events, treat with intravenous corticosteroids (initial dose of 1-2 mg/kg 
prednisone or equivalent) for 24 to 48 hours.  
o When symptoms improve to Grade 1 or less, a steroid taper should be started and 
continued over no less than 4 weeks. 
 
 Renal Failure or Nephritis: 
o For Grade 2 events, treat with corticosteroids (prednisone 1-2 mg/kg or equivalent). 
o For Grade 3-4 events, treat with systemic corticosteroids (prednisone 1-2 mg/kg or equivalent). 
o When symptoms improve to Grade 1 or less, steroid taper should be started and continued over 
no less than 4 weeks.  
 Myocarditis 
o Based on the severity of AE administer corticosteroids 
o Ensure adequate evaluation to confirm etiology and/or exclude other causes 
 All other Immune-related AEs 
o Based on type of and severity of AE administer corticosteroids 
o Ensure adequate evaluation to confirm etiology and/or exclude other causes

 Treatment of blood pressure increases associated with copanlisib  
It is important that patients with pre-existing arterial hypertension adhere to their regular 
medication schedule and take their usual doses on the days of study drug infusion.  
The management of acute blood pressure increases following copanlisib will need to be 
individualized for each patient, but prior experience suggested the benefit of dihydropyridine 
calcium channel blockers (i.e. amlodipine, felodipine). Nitrates should also be considered. Verapamil 
and diltiazem (non-dihydropyridine calcium channel blockers and moderate inhibitors of CYP 3A4) 
should be used with caution due to a potential CYP 3A4 interaction. In general, it is advisable for sites 
to be prepared, so that antihypertensive medication is readily available in case of need.  
In the event of the occurrence of arterial hypertension ≥ 150/90 mmHg during infusion of copanlisib 
at any cycle, antihypertensive treatment is suggested as indicated in section 5.2.1.3.5. In the event 
of the occurrence of CTCAE Grade 3 arterial hypertension (≥ 160/100 mmHg) during infusion of 
copanlisib, the infusion should be interrupted and antihypertensive treatment as suggested in 
section 5.2.1.3.5 should be administered. Infusion can be resumed when blood pressure has returned 
to <150/90 mmHg.

 Management of infusion-related hyperglycemia  
Mild to moderate asymptomatic increases of blood glucose may occur with copanlisib infusion, and with 
larger increases potentially occurring post-prandially. Please refer to table below for dose modifications 
and management of hyperglycemia. 
Asymptomatic glucose 
increases ≤ 250mg/dL 
(13.9 mmol/L) 
Does not generally require treatment with 
glucose lowering medication. 
Oral Hydration 
Asymptomatic glucose 
increase  > 250 mg/dl 
(13.9 mmol/L) 
• Repeat glucose testing. 
• If glucose value is decreasing, glucose level  
may be followed without glucose lowering 
medication treatment if hydration status is 
normal as clinically assessed 
• Consultation with endocrinologist is 
recommended 
• Oral and or IV Hydration as appropriate  
 
Symptomatic 
or 
persisting 
glucose 
increase               > 
250mg/dL 
(13.9 
mmol/L) 
• Hydration status should be clinically assessed.  
• If clinical assessment is consistent with 
dehydration, fluids should be given as 
clinically appropriate (orally or IV). 
• Laboratory test confirming increase should be 
repeated. If the repeated glucose value is 
persistent and/or patient is symptomatic 
and/or the hydration status indicates the 
need for hydration, glucose lowering 
medication should be administered. 
• Prompt input from an endocrinologist should 
be obtained.  
• Keep well hydrated rapid/ short acting 
insulin may be given if glucose 
persisting at > 250 mg/dL (13.9 
mmol/L), and the patient is 
symptomatic  
• 
Rapid/short acting insulin   according 
to the institution sliding scale coverage 
of glucose persisting at > 250 mg/dL 
(13.9 mmol/L) is recommended, with 
oral or IV hydration as clinically 
appropriate  
Asymptomatic Glucose 
increase > 500mg/dL 
• 
Will require dose reduction for 
subsequent treatment infusions. 
• 
Repeat glucose testing. 
• 
If glucose value is decreasing, glucose 
levels may be followed without glucose 
lowering medication treatment if 
hydration status is normal as clinically 
assessed 
Consultation 
with 
endocrinologist 
is 
recommended 
• Keep well hydrated rapid/ short acting 
insulin may be given if glucose 
persisting at > 250 mg/dL (13.9 
mmol/L), and the patient is 
symptomatic  
• For insulin naïve patients, monitor for 
signs of hypoglycemia 3 hours post 
insulin administration due to risk for 
hypoglycemic events.

 Treatment with glucose lowering medication suggested 
according the local standards of practice 
 
 
5.5 
Diet/Activity/Other Considerations 
5.5.1 Diet 
Subjects should maintain a normal diet unless modifications are required to manage an AE such as 
diarrhea, nausea or vomiting. 
 
5.5.1.1 Recommendations on meal timing on infusion days (copanlisib) 
Because of its inhibitory effect on the PI3K α-isoform, which is implicated in insulin metabolism, 
copanlisib infusions could be associated with a temporary increase in blood glucose. Addition of a meal 
in close proximity to copanlisib infusion may exacerbate glucose increase. It is recommended that timing 
and content of caloric intake on infusion days is monitored by the investigators. Consultation with a 
diabetologist or endocrinologist is advised. 
The investigator will review the glucose profile during and post the copanlisib infusions.  
Timing and content of caloric intake on infusion days will be managed by the investigator. Consultation 
with treating physician or diabetes/endocrinology physician is advised. 
The investigator may manage the timing of post infusion meals based on the glucose profile during prior 
infusion(s) to minimize glucose increases. This is in addition to glucose lowering medication.  
Low glycemic index meals (see Appendix 4) should be provided for patients who are kept in clinic for 
continued observation.  
A low glycemic index diet is recommended for the first 48 hours after study drug infusion. However, 
caloric restriction is not intended for the population under study. 
All glucose measurements, oral glucose lowering medication and/or insulin administration, if applicable, 
and meal timing will be collected as part of the clinical source documentation.  
NOTE: Caloric intake and timing recommendations for diabetic patients who require insulin treatment 
prior to the infusion at any cycle visit should be managed by the investigator based on consultation with 
treating physician or diabetes/endocrinologist physician. 
 
5.5.2 Contraception 
Pembrolizumab and copanlisib may have adverse effects on a fetus in utero.  Furthermore, it is not 
known if pembrolizumab and copanlisib have transient adverse effects on the composition of sperm.  
Non-pregnant, non-breast-feeding women may be enrolled if they are willing to use 2 methods of birth 
control or are considered highly unlikely to conceive.  Highly unlikely to conceive is defined as 1) 
surgically sterilized, or 2) postmenopausal (a woman who is ≥45 years of age and has not had menses 
for greater than 1 year will be considered postmenopausal), or 3) not heterosexually active for the 
duration of the study.  The two birth control methods can be either two barrier methods or a barrier

method plus a hormonal method to prevent pregnancy. Subjects should start using birth control from 
study Visit 1 throughout the study period up to 120 days after the last dose of study therapy.  
 
The following are considered adequate barrier methods of contraception: diaphragm, condom (by the 
partner), copper intrauterine device, sponge, or spermicide.  Appropriate hormonal contraceptives will 
include any registered and marketed contraceptive agent that contains an estrogen and/or a 
progestational agent (including oral, subcutaneous, intrauterine, or intramuscular agents). 
 
Subjects should be informed that taking the study medication may involve unknown risks to the fetus 
(unborn baby) if pregnancy were to occur during the study.  In order to participate in the study, they 
must adhere to the contraception requirement (described above) for the duration of the study and 
during the follow-up period. If there is any question that a subject will not reliably comply with the 
requirements for contraception, that subject should not be entered into the study. 
 
5.5.3 Use in Pregnancy 
If a subject inadvertently becomes pregnant while on treatment with pembrolizumab and/or copanlisib, 
the subject will immediately be removed from the study.  The site will contact the subject at least 
monthly and document the subject’s status until the pregnancy has been completed or terminated.  The 
outcome of the pregnancy will be reported to the Sponsor, Merck and Bayer without delay and within 
24 hours if the outcome is a serious adverse experience (e.g., death, abortion, congenital anomaly, or 
other disabling or life-threatening complication to the mother or newborn).  The study investigator will 
make every effort to obtain permission to follow the outcome of the pregnancy and report the condition 
of the fetus or newborn to the Sponsor.   If a male subject impregnates his female partner the study 
personnel at the site must be informed immediately and the pregnancy reported to the Sponsor, Merck, 
Bayer and followed. 
 
5.5.4 Use in Nursing Women 
It is unknown whether pembrolizumab and copanlisib is excreted in human milk.  Since many drugs are 
excreted in human milk, and because of the potential for serious adverse reactions in the nursing infant, 
subjects who are breast-feeding are not eligible for enrollment. 
 
5.6 
Participant Withdrawal/Discontinuation Criteria 
Participants may withdraw consent at any time for any reason or be dropped from the trial at the 
discretion of the investigator should any untoward effect occur.  In addition, a participant may be 
withdrawn by the investigator or the Sponsor if enrollment into the trial is inappropriate, the trial plan 
is violated, or for administrative and/or other safety reasons.  Specific details regarding discontinuation 
or withdrawal are provided in Section 7.1.4 – Other Procedures. 
 
A participant must be discontinued from the trial for any of the following reasons: 
 The subject or legal representative (such as a parent or legal guardian) withdraws consent. 
 Disease progression (for definition see Appendix 12.3 Measurement of Effects) 
 Unacceptable adverse experiences as described in Section 5.2.1.2 
 Intercurrent illness that prevents further administration of treatment

Version Date 01/13/2020 
 Investigator’s decision to withdraw the subject 
 The participant has a confirmed positive serum pregnancy test 
 Noncompliance with trial treatment or procedure requirements 
 The subject is lost to follow-up 
 Completed 36 cycles of treatment with pembrolizumab (Cohort 1) 
Note: Subjects who stop pembrolizumab after 36 cycles may be eligible for up to 18 cycles of 
additional study treatment if they progress after stopping study treatment provided they meet 
the requirements detailed in Section 5.8. 
 Administrative reasons 
 Completed 36 cycles with the combination of MK3475 and copanlisib 
 
The End of Treatment and Follow-up visit procedures are listed in Section 6 (Protocol Flow Chart) and 
Section 7.1.5 (Visit Requirements).  After the end of treatment, each subject will be followed for 30 days 
for adverse event monitoring (events of clinical interest will be collected for 90 days after the end of 
treatment as described in Section 5.4).  Subjects who discontinue for reasons other than progressive 
disease will have post-treatment follow-up for disease status until disease progression, initiating a non-
study cancer treatment, withdrawing consent, end of study or becoming lost to follow-up.  After 
documented disease progression each subject will be followed by telephone for overall survival until 
death, withdrawal of consent, or the end of the study, whichever occurs first. 
 
5.7 
Clinical Criteria for Early Trial Termination 
Early trial termination will be the result of the criteria specified below: 
 
1. Quality or quantity of data recording is inaccurate or incomplete 
2. Poor adherence to protocol and regulatory requirements 
3. Incidence or severity of adverse drug reaction in this or other studies indicates a potential health 
hazard to subjects 
4. Plans to modify or discontinue the development of the study drug 
 
In the event of Merck or Bayer decision to no longer supply study drug, ample notification will be 
provided so that appropriate adjustments to subject treatment can be made. 
 
5.8 
Retreatment 
Patients will be eligible for retreatment with pembrolizumab and/or copanlisib after completion of the 
trial treatment IF they achieved a complete response during the treatment phase AND remained in a 
complete remission until completion of the trial phase (36 cycles) AND experience a documented relapse 
within one year after completion of the trial phase. Retreatment will have to be discussed with the 
sponsor and will at most be for another 18 cycles. Prior to retreatment the patient will have to fulfill all 
the initial eligibility criteria as outlined in Section 5.1 Entry Criteria.

A 
Total of 36 treatment cycles  
B 
Patients should be assessed every 12 weeks (84 ± 7 days) for the first 2 years (or until disease progression) clinically for disease status - see section 7.1.5.4. Once a subject experiences confirmed disease progression 
or starts a new anti-cancer therapy they move into survival follow-up  
C 
Check during treatment phase once every cycle. 
D 
Preferably FDG PET/CT at baseline, but if unavailable a contrast-enhanced CT scan is allowed. If PET CT is performed, the CT component must be of diagnostic quality. Subsequent imaging should be of the same 
modality as the imaging at baseline – see Sections 7.1.2.6 and 12.3.  Once a patient achieved at PET-negative CR after completion of treatment, subsequent imaging can be a contrast-enhanced CT scan only. The first 
imaging during the treatment phase will be within 1 week prior to or on the day of starting treatment cycle 5; subsequent imaging will be every 12 weeks (± 3days) thereafter during the treatment phase (i.e.  within 
1 week prior to or on the day of starting treatment C9D1, C13D1, C17D1,…etc). Scan at the end of treatment should be performed within 14 days of the visit. 
E 
Radiologic imaging to monitor disease status will be performed every 12 weeks (84 ± 7 days) for the first 24 months (year 1&2 of follow-up), then every 26 weeks (182 ± 14 days) for the next year after completing 
therapy (year 3 of follow-up).  After 3 years, patient will be followed clinically every 3-6 months with diagnostic imaging only as clinically indicated. 
F 
Peripheral blood samples will be collected immediately prior to the induction phase on day -21 (time 1); induction on day -7 (time 2); cycle 2 day 1, immediately prior to dose 2 (time 3); prior to dose 3, cycle 3  day 1 
(time 4); prior to dose 5, cycle 5 day 1 (time 5); prior to dose 9, cycle 9 day 1 (time 6); and at time of progression (time 7) or end of treatment due to toxicity. Blood for correlative studies must be collected from Mon-
Thurs so that it can be processed immediately at Fox Chase Cancer Center. Also, blood for correlative must not be collected a day before a holiday. Blood must reach Fox Chase Cancer Center on a working day. 
G 
Within 10 days of treatment initiation 
H 
Within 72 hours of treatment initiation if participant is a woman of child bearing potential. After that as per institutional practice.  
I 
Vital signs consist of temperature, pulse, respiration, and blood pressure and will be monitored every 15 minutes during the pembrolizumab infusion and for 60 minutes after completion of each infusion. Copanlisib 
administration will have blood pressure measured through observation period. 
J 
A direct bilirubin must be performed if the total bilirubin is above the upper limit of normal. Serum chemistry includes test for albumin, alkaline phosphatase, total bilirubin, bicarbonate, BUN, calcium, chloride, 
creatinine, glucose, potassium, sodium, total protein, SGOT [AST], SGPT [ALT].

L    For patients undergoing PET/CT, response will also be assessed using the 5-point scale (Deauville criteria).2 Refer to section 13 for measurements of effect. 
M  Blood glucose levels and Blood pressure measurement (not more than 4 per visit) must be done before copanlisib administration on day -21 and day -14 and conditions as described in section 5.2.2.2 must be met for 
drug administration during the induction phase alone. During copanlisib administration, blood pressure should be measured at 30 min (during infusion), and 60 min (end of infusion) from start of the infusion, 1 hr 
and 2 hr (after the infusion). 
N.  Patients in cohort 2 who will receive copanlisib must be fasting for at least 8 hours before the drug administration on Day -21 of the induction phase. Blood glucose level should be monitored and copanlisib may not 
be given if blood glucose level is higher than 160 mg/dl. Follow guidelines as described in section 5.2.2.2 for copanlisib administration. 
O. Day 8 treatment of each cycle with copanlisib may not take place (see section 4.2.3.1) if RP2D is dose level -1. If Day 8 treatment does not take place all visit related activities on day 8 will also not happen. 
P. Before starting copanlisib, all patients should have CMV status assessed. For seropositive patients, CMV quantitative polymerase chain reaction (PCR) testing with every cycle. Interrupt Copanlisib in patients with 
evidence of active CMV infection of any grade or viremia until the viremia has resolved. Ganciclovir or valganciclovir should be preemptively initiated in patients with positive CMV PCR and symptoms consistent with 
CMV infection, patients presenting with fever and no clear source in whom quantitative CMV testing is unavailable, and asymptomatic patients with increasing viral load. Patients can continue with pembrolizumab 
while copanlisib is being held. 
Q   In cohort 2, on the days when patients receive both the drugs, sequence of administration must be copanlisib, followed by pembrolizumab.

7.0 TRIAL PROCEDURES 
7.1 
 Trial Procedures 
The Trial Flow Chart - Section 6.0 summarizes the trial procedures to be performed at each visit.  
Individual trial procedures are described in detail below.  It may be necessary to perform these 
procedures at unscheduled time points if deemed clinically necessary by the investigator. 
Furthermore, additional evaluations/testing may be deemed necessary by the Sponsor and/or Merck, 
Bayer for reasons related to subject safety. In some cases, such evaluation/testing may be potentially 
sensitive in nature (e.g., HIV, Hepatitis C, etc.), and thus local regulations may require that additional 
informed consent be obtained from the subject.  In these cases, such evaluations/testing will be 
performed in accordance with those regulations. 
 
7.1.1 Administrative Procedures 
7.1.1.1 Informed Consent 
The Investigator must obtain documented consent from each potential subject prior to participating in 
a clinical trial. 
 
7.1.1.1.1 
General Informed Consent 
Consent must be documented by the subject’s dated signature or by the subject’s legally acceptable 
representative’s dated signature on a consent form along with the dated signature of the person 
conducting the consent discussion.  
A copy of the signed and dated consent form should be given to the subject before participation in the 
trial. 
 
The initial informed consent form, any subsequent revised written informed consent form and any 
written information provided to the subject must receive the IRB’s approval/favorable opinion in 
advance of use.  The subject or his/her legally acceptable representative should be informed in a timely 
manner if new information becomes available that may be relevant to the subject’s willingness to 
continue participation in the trial.  The communication of this information will be provided and 
documented via a revised consent form or addendum to the original consent form that captures the 
subject’s dated signature or by the subject’s legally acceptable representative’s dated signature. 
Specifics about a trial and the trial population will be added to the consent form template at the protocol 
level.   
 
The informed consent will adhere to IRB requirements, applicable laws and regulations and Sponsor 
requirements. 
 
7.1.1.2 Inclusion/Exclusion Criteria 
All inclusion and exclusion criteria will be reviewed by the investigator or qualified designee to ensure 
that the subject qualifies for the trial.

Version Date 01/13/2020 
7.1.1.3 Medical History 
A medical history will be obtained by the investigator or qualified designee.  Medical history will include 
all active conditions, and any condition diagnosed within the prior 10 years that are considered to be 
clinically significant by the Investigator.  Details regarding the disease for which the subject has enrolled 
in this study will be recorded separately and not listed as medical history.   
 
7.1.1.4 Prior and Concomitant Medications Review 
7.1.1.4.1 
Prior Medications 
The investigator or qualified designee will review prior medication use, including any protocol-specified 
washout requirement, and record prior medication taken by the subject within 28 days before starting 
the trial.  Treatment for the disease for which the subject has enrolled in this study will be recorded 
separately and not listed as a prior medication.  
 
7.1.1.4.2 
Concomitant Medications 
The investigator or qualified designee will record medication, if any, taken by the subject during the trial.  
All medications related to reportable SAEs and ECIs should be recorded as defined in Section 8.0. 
 
7.1.1.5 Disease Details and Treatments 
 
7.1.1.5.1 
Disease Details 
The investigator or qualified designee will obtain prior and current details regarding disease status.  
 
7.1.1.5.2 
Prior Treatment Details 
The investigator or qualified designee will review all prior cancer treatments including systemic 
treatments, radiation and surgeries. 
 
7.1.1.5.3 
Subsequent Anti-Cancer Therapy Status 
The investigator or qualified designee will review all new anti-neoplastic therapy initiated after the last 
dose of trial treatment.  If a subject initiates a new anti-cancer therapy within 30 days after the last dose 
of trial treatment, the 30 day Safety Follow-up visit must occur before the first dose of the new therapy.  
Once new anti-cancer therapy has been initiated the subject will move into survival follow-up.  
 
7.1.2 Clinical Procedures/Assessments 
7.1.2.1 Adverse Event (AE) Monitoring 
The investigator or qualified designee will assess each subject to evaluate for potential new or worsening 
AEs as specified in the Trial Flow Chart and more frequently if clinically indicated.  Adverse experiences 
will be graded and recorded throughout the study and during the follow-up period according to NCI 
CTCAE Version 5.0 (see Section 14.2).  Toxicities will be characterized in terms regarding seriousness, 
causality, toxicity grading, and action taken with regard to trial treatment.  
All AEs of unknown etiology associated with pembrolizumab exposure should be evaluated to determine 
if it is possibly an event of clinical interest (ECI) of a potentially immunologic etiology (irAE).  See Section

Version Date 01/13/2020 
5.4 regarding the identification, evaluation and management of AEs of a potential immunological 
etiology.   
 
Please refer to section 8.0 for detailed information regarding the assessment and recording of AEs.   
 
7.1.2.2 Full Physical Exam 
The investigator or qualified designee will perform a complete physical exam during the screening 
period.  Clinically significant abnormal findings should be recorded as medical history.  A full physical 
exam will also be performed every 3 cycles during the treatment phase, 30 days post treatment, and 
every 3 months during follow-up. 
 
7.1.2.3 Directed Physical Exam 
For cycles that do not require a full physical exam per the Trial Flow Chart, the investigator or qualified 
designee will perform a directed physical exam as clinically indicated prior to trial treatment 
administration.   
 
7.1.2.4 Vital Signs 
The investigator or qualified designee will take vital signs at screening, prior to the administration of 
each dose of trial treatment and at treatment discontinuation as specified in the Trial Flow Chart (Section 
6.0).  Vital signs should include temperature, pulse, respiratory rate, weight and blood pressure.  Height 
will be measured at screening only. 
 
7.1.2.5 Eastern Cooperative Oncology Group (ECOG) Performance Scale 
The investigator or qualified designee will assess ECOG status (see Section 14.1) at screening, prior to 
the administration of each dose of trial treatment and discontinuation of trial treatment as specified in 
the Trial Flow Chart.  After Cycle 8 assessment of ECOG status will be performed every other cycle in 
conjunction with the directed or full physical exam. 
 
7.1.2.6 Tumor Imaging and Assessment of Disease 
Scans will be performed at baseline, and thereafter every 12 weeks (± 3 days) while on treatment.  
Imaging during follow up is outlined in section 7.1.5.4. It is critical that all FDG PET/CT or CT scans be 
performed in an identical way to the baseline scan with the same scan direction and consistent arm 
pointing. The interval between FDG injection and initiation of emission scanning should be the same or 
similar to the baseline scan. If tumor flare is suspected, the patient must undergo a second scan within 
a month of the first scan and the case must be discussed with the principle investigator. If progression is 
documented at that time, patient must come off study. A scan should be performed within 14 days of 
the end of treatment visit. 
 
7.1.2.7 Tumor Tissue Collection and Correlative Studies Blood Sampling 
 For details in regards to tumor tissue collection please see Section 7.1.3.1.2 Tumor tissue collection for 
central pathology review and correlative studies and the trial lab manual.

7.1.4 Other Procedures 
7.1.4.1 Withdrawal/Discontinuation 
When a subject discontinues/withdraws prior to trial completion, all applicable activities scheduled for 
the final trial visit should be performed at the time of discontinuation.  Any adverse events, which are 
present at the time of discontinuation/withdrawal, should be followed in accordance with the safety 
requirements outlined in Section 8.0 - Assessing and Recording Adverse Events.  Subjects who a) attain 
a CR or b) complete 36 cycles of treatment with pembrolizumab may discontinue treatment with the 
option of restarting treatment if they meet the criteria specified in Section 5.1.  After discontinuing 
treatment following assessment of CR, these subjects should return to the site for a Safety Follow-up 
Visit (described in Section 7.1.5.3.1) and then proceed to the Follow-Up Period of the study (described 
in Section 7.1.5.4). 
 
7.1.5 Visit Requirements 
Visit requirements are outlined in Section 6.0 - Trial Flow Chart.    
 
7.1.5.1 Screening 
7.1.5.1.1 
Screening Period 
Subjects will be screened within 28 prior to protocol treatment. Study procedures and information 
regarding the nature of the study will be reviewed with potential subjects and written informed consent 
will be obtained prior to any study related procedures. Screening procedures are described in Section 
6.0 – Trial Flow Chart. 
 
7.1.5.2 Treatment Period 
Subjects will be treated every 3 weeks of pembrolizumab for up to 36 cycles. During the treatment phase 
patients will be evaluated prior to any treatment dose of pembrolizumab for toxicities and every 3 
months for disease progression as outlined in detail in Section 6.0 – Trial Flow Chart. 
 
7.1.5.3 Post-Treatment Visits 
7.1.5.3.1 
Safety Follow-Up Visit 
The mandatory Safety Follow-Up Visit should be conducted approximately 30 days after the last dose of 
trial treatment or before the initiation of a new anti-cancer treatment, whichever comes first.  All AEs 
that occur prior to the Safety Follow-Up Visit should be recorded.  Subjects with a study drug attributable 
AE of Grade > 1 will be followed until the resolution of the AE to Grade 0-1 or until the beginning of a 
new anti-neoplastic therapy, whichever occurs first.  Events of Clinical Interest that occur within 90 days 
of the end of treatment or before initiation of a new anti-cancer treatment should also be followed and 
recorded.

Version Date 01/13/2020 
7.1.5.4 Follow-up Visits 
Subjects who discontinue trial treatment for a reason other than disease progression will move into the 
Follow-Up Phase and should be assessed every 12 weeks (84 ± 7 days) for the first 2 years clinically for 
disease progression. Radiologic imaging (see Section 14.3 Measurement of Effect) to monitor disease 
status will be performed every 12 weeks (84 ± 7 days) for the first 24 months (year 1 & 2 of follow-up), 
then every 26 weeks (182 ± 14 days) for the next year after completing therapy (year 3 of follow-up).  
After 3 years patient will be followed clinically every 3-6 months with diagnostic imaging only as clinically 
indicated. Every effort should be made to collect information regarding disease status until the start of 
new anti-neoplastic therapy, disease progression, death, end of the study or if the subject begins 
retreatment with pembrolizumab as detailed in Section 5.8.  Information regarding post-study anti-
neoplastic treatment will be collected if new treatment is initiated. 
 
7.1.5.4.1 
Survival Follow-up 
Once a subject experiences confirmed disease progression or starts a new anti-cancer therapy, the 
subject moves into the survival follow-up phase. Survival follow-up will take place approximately every 
12 weeks to assess for survival status until death, withdrawal of consent, or the end of the study, 
whichever occurs first. This contact can be done by telephone, medical record search, office visit, etc.  
After 3 years of follow-up this contact can go to every 6 month.  
 
8.0 Assessing and Recording Adverse Events 
Adverse Events (AE) is any unfavorable and unintended sign (including an abnormal laboratory finding), 
symptom or disease temporally associated with the use of a medicinal (investigational) product, 
treatment or procedure regardless of whether it is considered related to the medical treatment or 
procedure (NCI CTEP Guidelines March 28, 2011)  
 
Serious Adverse Event (SAE) is an AE that results in the following outcomes- 
 
 Death 
 Life threatening adverse event 
 Requires inpatient hospitalization or prolongation of existing hospitalization (for > 24 
hours),  
 A persistent or significant incapacity or substantial disruption of the ability to conduct 
normal life functions, 
 Congenital anomaly/ birth defect.  
 
A “life-threatening” adverse event places the patient at immediate risk of death in the 
judgment of the investigator or sponsor. 
 
NOTE: Important medical event that may not result in death, be life threatening, or require 
hospitalization may be considered an SAE when, based upon appropriate medical judgment, may 
jeopardize the subject and may require medical or surgical intervention to prevent any of the above 
outcomes.

8.1 
Severity Rating  
The investigator will evaluate the severity of each adverse event.  NCI Common Terminology Criteria 
for Adverse Events (CTCAE v.5.0) or study specific toxicity tables provided in the protocol define 
severity.  If not included in CTCAE v.5.0, severity is expressed in numerical grade using the following 
definitions: 
 
Grade 1: Mild-asymptomatic or mild symptoms; clinical or diagnostic observations only; 
intervention not indicated. 
 
Grade 2: Moderate-minimal, local or noninvasive intervention indicated; limiting age 
appropriate instrumental ADL. 
 
Grade 3: Severe-severe or medically significant but not immediately life-threatening; 
hospitalization or prolongation of hospitalization indicated; disabling; limiting self-care ADL. 
 
Grade 4: Life-threatening consequences; urgent intervention indicated.  
 
Grade 5: Death related to AE 
 
8.2 
Attribution/Relationship to study drug  
 Definite – clearly related 
 Probable – likely related 
 Possible – may be related 
 Unlikely – doubtfully related 
 Unrelated – clearly not related 
 
8.3 
Expectedness 
 An Expected Adverse Event is one where the specificity or severity is consistent with the current 
information available from the resources. 
An Unexpected Adverse Event is one where the nature, severity, or frequency of the event is related to 
participation in the research is not consistent with either: 
 
1. The known or foreseeable risk of adverse events associated with the procedures involved in the 
research that are described in (a) the protocol-related documents, such as the IRB-approved 
research protocol, any applicable investigator brochure, and the current IRB-approved 
informed consent document, and (b) other relevant sources of information, such as product 
labeling and package inserts: or 
 
2. The expected natural progression of any underlying disease, disorder, or condition of the 
subject (s) experiencing the adverse event and the subjects(s) predisposing risk factor profile 
for the adverse event.

9.0 RECORDING AND REPORTING RESPONSIBILITIES 
9.1.1 Investigative Site Recording Responsibilities: 
1. Upon identification of an AE or SAE, the site investigator will utilize the above 
definitions to properly classify attribution and expectedness of the event.  These must 
be recorded for each event. 
 
2. All AEs and SAEs will be recorded in the “AE case report forms” (CRF) and in progress 
reports with details about the grade and attribution of each episode, action taken with 
respect to the study drug, and the patient’s outcome will be recorded in the CRF.  All 
events will be recorded on case report forms for the duration of the study until they 
resolve. 
 
3. All SAEs will be recorded on the FDA MedWatch form 3500a. The attribution and 
expectedness must be recorded on the MedWatch form. If this information is not 
available at the time of initial reporting, a final report must be documented with 
attribution and expectedness.  It may be necessary to submit follow up reports to the 
Sponsor should the event require further investigation. All subsequent SAEs must be 
recorded for up to 30 days after the last treatment. 
 
4. All patient data must be recorded in eCRFs by the investigative site within 7 days of the 
patient’s visit. eCRFs will be available through Oncore electronic data capture system. 
 
9.1.2  Investigative Site Reporting Responsibilities: 
1. The investigator/ site is responsible to report all SAEs that occur on or after the first 
day of study treatment to the sponsor within 24 hours of becoming aware of the 
event. It may be necessary to submit a final SAE report if the initial report did not 
have the complete information. All subsequent SAEs must be recorded for up to 30 
days after the last treatment.  
 
 
Each investigator is responsible to report all AEs/SAEs to their local IRB following 
guidelines set by that IRB.  The FCCC OCR reserves the right to request an event be 
reported to the IRB at their discretion.  Copies of events reviewed by the IRB must 
be sent by email to SAE.FCCC@fccc.edu. 
 
2. If the investigator or IRB feels the event warrants a revision to the informed consent 
that was not already initiated by the ISRU, draft revisions will be made in track 
changes and submitted to the ISRU for consideration.  Any consent revisions must 
receive ISRU approval prior to submission to the IRB. 
 
3. Any investigator who is in doubt of whether a particular AE needs to be reported is 
directed to call the Study Monitor for confirmation with the Sponsor-Investigator 
 
4. If the results of an investigator or ISRU investigation show an adverse event not 
initially determined to be reportable is so reportable (to IRB or FDA), the investigator

will report the event following the above guidelines based on the date the 
determination is made. 
 
5. Investigative site should report Reportable New Information (RNI) to their local IRB 
according to the local IRB guidelines. This information should also be sent to ISRU. At 
minimum serious unexpected events that are associated with the treatment are 
considered to be reportable. Expected AEs that are experienced at a higher 
frequency or severity than expected in the patient population according to the 
investigator brochure are considered to be reportable. 
 
6. Copies of all related correspondence and reporting documents must be submitted to 
the ISRU and will be maintained in the trial master file.  
 
 
                                Participating sites should report events to: 
 
Investigator-Sponsored Research Unit

9.1.3 Sponsor Reporting Responsibilities: 
 Adverse events which meet all of the following criteria must be reported to all 
participating institutions for IRB submission within 2 weeks of notification of the 
event.   
 Unexpected (in terms of nature, severity, or frequency) given  
i. (a) the research procedures that are described in the protocol-related 
documents, such as the IRB-approved research protocol and informed 
consent document; and  
ii. (b) the characteristics of the subject population being studied; 
 Possibly related to participation in the research (possibly related means there 
is a reasonable possibility that the incident, experience, or outcome may have 
been caused by the procedures involved in the research); and 
 Serious (refer to above definition) or otherwise one that suggests that the 
research places subjects or others at a greater risk of physical or psychological 
harm than was previously known or recognized. 
 If the adverse event requires modification of the study protocol and informed consent, 
these changes will be provided to all participating institutions in the form of an 
amendment from the ISRU for each site’s IRB of record along with the report of the 
adverse event.   
 All participating sites must be notified of all amendments approved by FCCC IRB; or if 
the study is suspended such that the participating sites cannot accrue patients in the 
study until further notification. 
 All participating sites must be notified when the study is closed by IRB.

9.2 
Definition of an Overdose  
For purposes of this trial, an overdose will be defined as any dose exceeding the prescribed dose for 
pembrolizumab by 20% over the prescribed dose. No specific information is available on the treatment 
of overdose of pembrolizumab. In the event of overdose, pembrolizumab should be discontinued and 
the subject should be observed closely for signs of toxicity.  Appropriate supportive treatment should be 
provided if clinically indicated. 
 
If an adverse event(s) is associated with (“results from”) the overdose of a Merck product, the adverse 
event(s) is reported as a serious adverse event, even if no other seriousness criteria are met. 
 
If a dose of Merck’s product meeting the protocol definition of overdose is taken without any associated 
clinical symptoms or abnormal laboratory results, the overdose is reported as a non-serious Event of 
Clinical Interest (ECI), using the terminology “accidental or intentional overdose without adverse effect.” 
 
9.3 
Events of Clinical Interest 
Selected non-serious and serious adverse events are also known as Events of Clinical Interest (ECI) and 
must be recorded as such on the Adverse Event case report forms/worksheets and reported within 24 
hours to the Sponsor, who will report this information within 2 working days to Merck Global Safety. 
 
Events of clinical interest for this trial include:

Version Date 01/13/2020 
 
1.  An overdose of Merck product, as defined in Section 9.2, that is not associated with clinical symptoms 
or abnormal laboratory results.  
2.  An elevated AST or ALT lab value that is greater than or equal to 3X the upper limit of normal and an 
elevated total bilirubin lab value that is greater than or equal to 2X the upper limit of normal and, at the 
same time, an alkaline phosphatase lab value that is less than 2X the upper limit of normal, as 
determined by way of protocol-specified laboratory testing or unscheduled laboratory testing. 
3.  In the event a subject develops any of the following AEs, a detailed narrative of the event should be 
reported as an ECI to the Sponsor within 24 hours, who will report this information within 2 working 
days to Merck Global Safety: 
 
a.  Grade ≥ 3 diarrhea 
b.  Grade ≥ 3 colitis 
c.  Grade ≥ 2 pneumonitis 
d.  Grade ≥ 3 hypo- or hyperthyroidism 
 
A comprehensive list of ECI is also provided in the appendix (Appendix 13.4 - Events of Clinical Interest 
(ECI) guidance). This appendix provides guidance regarding identification, evaluation and management 
of ECIs and irAEs.  Additional ECIs are identified in this guidance document and also need to be reported 
to the Sponsor within 24 hours, who will report this information within 2 working days to Merck Global 
Safety.   
Subjects should be assessed for possible ECIs prior to each dose.  Lab results should be evaluated and 
subjects should be asked for signs and symptoms suggestive of an immune-related event.  Subjects who 
develop an ECI thought to be immune-related should have additional testing to rule out other etiologic 
causes.  If lab results or symptoms indicate a possible immune-related ECI, then additional testing should 
be performed to rule out other etiologic causes.  If no other cause is found, then it is assumed to be 
immune-related.  
 
ECIs that occur in any subject from the date of first dose through 90 days following cessation of 
treatment, or the initiation of a new anticancer therapy, whichever is earlier, whether or not related to 
the Merck’s product, must be reported within 24 hours to the Sponsor, who will report this information 
within 2 working days to Merck Global Safety. 
 
9.4 
Reporting of Pregnancy and Lactation to the Sponsor-Investigator and to Merck and Bayer 
Although pregnancy and lactation are not considered adverse events, it is the responsibility of 
investigators or their designees to report any pregnancy or lactation in a subject (spontaneously 
reported to them), that occurs during the trial or within 120 days of completing the trial completing the 
trial, or 30 days following cessation of treatment if the subject initiates new anticancer therapy, 
whichever is earlier.  All subjects who become pregnant must be followed to the completion/termination 
of the pregnancy.  Pregnancy outcomes of spontaneous abortion, missed abortion, benign hydatidiform 
mole, blighted ovum, fetal death, intrauterine death, miscarriage and stillbirth must be reported as 
serious events (Important Medical Events).  If the pregnancy continues to term, the outcome (health of 
infant) must also be reported to Merck and Bayer.

10.0 STATISTICAL ANALYSIS PLAN 
10.1 Statistical Analysis Plan (cohort 1) 
The primary endpoint is based on the median progression free survival (PFS). Estimates are based on 
historical controls from published data.31,33,34,78 We will test the null hypothesis that median PFS is at 
most 3 months versus the alternative that it is at least 6 months. We will use a two-stage design with 
early stopping rules79 and enroll an initial cohort of 13 patients. We will terminate the study for futility 
unless more than 6 patients are progression-free (as defined alive and achieving SD, PR or CR as per 
revised Cheson response criteria) at 3 months. Otherwise we will recruit an additional 11 patients and 
evaluate these 11 plus all eligible patients from the initial cohort (n=13) who were progression-free at 3 
months at 6 months. If at least 10 out of 24 patients have not progressed at 6 months we will reject the 
null hypothesis. Only those patients who have measurable disease present at baseline, have received at 
least one cycle of therapy, and have had their disease re-evaluated will be considered evaluable for 
response. (Note:  Patients who exhibit objective disease progression prior to the end of cycle 1 will also 
be considered evaluable.) Patients who are not evaluable for response will be replaced. However, all 
patients who received at least 1 dose of the study drug will be included in the safety analysis. The study 
has 80% power and 4.7% type I error. The chance of early stopping, after 13 patients, is 50% under the 
null and 5.5% in error.  
 
Early stopping rules for safety/adverse events:  
Adverse events will be assessed continuously throughout the study. If ever during evaluation of the first 
cohort of 13 eligible patients, 3 patients have to discontinue study treatment due to treatment related 
adverse events the study will be interrupted for consideration of dose reduction or termination. If ever 
4 of the 24 eligible patients have to discontinue study treatment due to treatment related adverse events 
the study will be suspended and early termination for excess toxicity will be considered after careful 
investigation of the causes of the higher than expected toxicities. Once the root of the higher than 
anticipated toxicities has been determined, the study team will confer with the FCCC DSMC and IRB to 
make a determination whether accrual can be resumed or the study will be terminated early. The chance 
of early termination with a true toxicity of 25% is 67%. The chance of early termination when true toxicity 
is 5% is 2.5%. The overall chance of study termination under the null of 5% true toxicity is 4.2% and is 
89% if true toxicity is 25%.  
 
Correlative studies: Due to this limited sample size, all exploratory analyses of associations of biomarkers 
with outcomes and changes in marker levels pre- and during treatment will be largely descriptive in 
nature. Multiple imputation will be used to account for missing data in order to provide an unbiased 
estimate.  
 
 
10.2 Statistical Analyses Plan (cohort 2) 
There will be a phase 1 part (cohort 2a), during which the recommended phase 2 dose (RPTD) of the 
combination of pembrolizumab and copanlisib will be determined, followed by a phase 2 portion (cohort 
2b), which will explore safety and efficacy of the combination. The phase 1 portion will follow a standard 
‘3+3’ escalation/de-escalation design as outlined above. A minimum of 4 and a maximum of 12 patients 
will be included in the phase 1 portion. For the phase 2 portion, an optimal Simon’s two-stage design 
will be used. The null hypothesis that the true response rate is 30% will be tested against the alternative

hypothesis of a true response rate ≥60%. Response is defined as either a partial or complete response 
by Revised Cheson criteria (see 13.3) by 4 cycles of treatment. All eligible and evaluable patients who 
received at least 1 dose of the combination regimen will be included in this response analysis. Patients 
who come off study prior to second clinic visit for reasons other than progressive disease will be 
replaced. Patients who are lost to follow-up after re-evaluation will be counted as failures and will not 
be replaced. For the first stage, 8 patients will be treated at the RPTD of the combination. If at least 4 
patients achieve a response, we will accrue 16 more for a total of 24 patients treated at the RPTD 
(including those patients treated during the phase 1 portion at the RPTD). If of the first 8 patients, 3 or 
less respond, the trial will be stopped. The null hypothesis will be rejected if 11 or more responses are 
observed in 24 patients and the combination deemed worthy of further consideration. This design yields 
a power of 80% with a type I error of 5% when the true response rate is ≥60% ORR. The probability of 
early stopping under the null hypothesis is 80%. 
 
Early stopping rules for safety/adverse events: A discontinuation rate for toxicities related to study 
treatment of ≤30% will be deemed acceptable, while a ≥50% discontinuation rate for toxicities related 
to study treatment will be considered unacceptable. An interim analysis will be conducted when 8 
patients have accrued to determine safety by the Principal Investigator and the statistician. If ≥4 of the 
initial 8 treated patients at the RPTD discontinue due to study related toxicities, the study will be stopped 
for safety. If after 24 patients have been enrolled, or at any time point during the study with treatment 
at the RPTD, 11 or more patients discontinue due to study related toxicities, the study will also be 
stopped for safety. With this design, the probability of stopping early with a ≥50% true toxicity rate is 
64%, and 19% if the true toxicity is ≤30%. The probability of stopping at any point due to a ≥50% true 
toxicity rate is 82%, while it is ≤22% if the true toxicity is 30%. 
 
Accrual: The expected monthly accrual rate is 1-2 patients. Thus, accrual is anticipated to take 
approximately 2.5 years.

14.3 Measurement of Effect  
Revised Cheson Lymphoma Response Criteria  
 
NOTE: These criteria are based upon the criteria from the Revised Response Criteria for Malignant 
Lymphoma, (Cheson et al.), Journal of Clinical Oncology, 2007, Vol. 25:579-586.  
 
The criteria use the following categories of response: Complete Response (CR), Partial Response (PR), 
Stable Disease (SD), Relapse and Progression (PD). In the case of stable disease, follow-up assessments 
must have met the SD criteria at least once after study entry at a minimum interval of six weeks.  
The following guidelines are to be used for establishing tumor measurements at baseline and for 
subsequent comparison:  
 The six largest dominant nodes or extranodal masses must be identified at baseline.  
 If there are 6 or fewer nodes and extranodal masses, all must be listed as dominant  
 If there are more than 6 involved nodes or extranodal masses, the 6 largest dominant nodes or 
extranodal masses should be selected according to the following features: a) they should be 
clearly measurable in at least two perpendicular measurements; b) they should be from as 
disparate regions of the body as possible; and c) they should include mediastinal and 
retroperitoneal areas of disease whenever these sites are involved.  
 Measurements for all dominant nodes and extranodal masses will be reported at baseline. 
Measurements on non-dominant nodes are not required.  
 The lymph nodes or extranodal masses selected for measurement should be measured in two 
perpendicular diameters, one of which is the longest perpendicular diameter. The lymph nodes 
should be measured in centimeters to the nearest one tenth of a centimeter (e.g.,2.0 cm, 
2.1cm, 2.2 cm, etc.)  
 The two measured diameters of each lymph node site or extranodal mass should be multiplied 
giving a product for each nodal site or extranodal mass. The product of each nodal site should 
be added, yielding the sum of products of the diameters (SPD). The SPD will be used in 
determining the definition of response for those who have less than a complete response.  
 Patients should be assessed with PET/CTs. Where PET is not available, response should be 
assessed as above, but only using CT scans. However, residual masses should not be assigned 
CRu status, but should be considered partial responses. 
 For patients undergoing PET/CT, tumor assessment at all timepoints should also include the 5-
point scale (Deauville criteria) as an adjunct to the Cheson criteria.2 Scoring guidelines for the 5-
point scale are below. A score of 1, 2, or 3 indicates a complete metabolic response. Refer to 
section 14.3.1 for further definition of complete response. 
 
1 
No uptake 
2 
≤ Mediastinal blood pool 
3 
> Mediastinum and ≤ liver 
4 
Moderately > liver at any site 
5 
Markedly increased uptake above liver and/or 
new sites of disease 
X 
New areas of uptake unlikely to be related to 
lymphoma

14.3.1 Complete Response  
Complete disappearance of all detectable clinical evidence of disease, and disease-related symptoms if 
present prior to therapy.  
 
In patients with a typically FDG-avid lymphoma with no pre-treatment PET scan, or for lymphomas for 
which the PET scan was positive prior to therapy: a post-treatment residual mass of any size is 
permitted as long as it is PET-negative. 
 
For variably FDG-avid lymphomas without a pretreatment PET scan, or if a pretreatment PET scan was 
negative: all lymph nodes and extranodal masses must have regressed on CT to normal size (≤ 1.5 cm in 
their greatest transverse diameter for nodes > 1.5 cm prior to therapy). Previously involved nodes that 
were 1.1-1.5 cm in their long axis and > 1.0 cm in their short axis prior to treatment must have 
decreased to ≤ 1 cm in their short axis after treatment 
 
The spleen and/or liver, if considered enlarged prior to therapy on the basis of a physical examination 
or CT scan, should not be palpable on physical examination, and nodules related to lymphoma should 
disappear. However, no normal size can be specified because of the difficulties in accurately evaluating 
splenic and hepatic size and involvement. For instance, a spleen considered normal size may contain 
lymphoma, whereas an enlarged spleen may not necessarily reflect the presence of lymphoma, but 
variations in anatomy, blood volume, the use of hematopoietic growth factors, or other causes.  
 
NOTE: Complete Remission/unconfirmed (CRu): Using the above definition for CR and that below for 
PR eliminates the category of CRu.  
 
14.3.2 Partial Response (PR)  
The designation of PR requires all of the following: A ≥ 50% decrease in sum of the product of the 
diameters (SPD) of up to 6 of the largest dominant nodes or extranodal masses.  
 
No increase in the size of other nodes, liver or spleen.  
 
No new sites of disease.  
 
For a typically FDG-avid lymphoma with no pretreatment PET scan or one that was PET-positive prior 
to therapy, the post-treatment PET should be positive at any previously involved sites.  
 
For variably FDG-avid lymphomas/FDG-avidity unknown, without a pre-treatment PET scan, or if a 
pretreatment PET scan was negative, CT scan criteria should be used.  
 
Patients who achieve a CR by the above criteria, but who have persistent morphologic bone marrow 
involvement will be considered partial responders.  
 
When the bone marrow was involved before therapy and a clinical CR was achieved, but with no bone 
marrow assessment after treatment, patients should be considered partial responders.

14.3.3 Stable Disease (SD)  
Failing to attain the criteria needed for a PR or CR, but not fulfilling those for progressive disease (see 
below).  
 
Typically FGD-avid lymphomas: The PET should be positive at prior sites of disease with no new areas 
of involvement on the post-treatment CT or PET.  
 
 For variably FDG-avid lymphomas/FDG-avidity unknown: For patients without a pretreatment PET scan 
or if the pre-treatment PET was negative, there must be no change in the size of the previous lesions 
on the post-treatment CT scan.  
 
14.3.4 Progression (PD) and Relapse  
For determination of relapsed and progressive disease, lymph nodes should be considered abnormal if 
the long axis is more than 1.5 cm, regardless of the short axis. If a lymph node has a long axis of 1.1 to 
1.5 cm, it should only be considered abnormal if the short axis is more than 1 cm. Lymph nodes ≤ 1 x ≤ 
1 cm will not be considered as abnormal for relapse or progressive disease.  
 
Treatment decisions in patients with presumed refractory, relapsed or progressive disease should not 
be made solely on the basis of a single PET scan without histologic confirmation.  
 
Appearance of any new lesion more than 1.5 cm in any axis during or at the end of therapy, even if 
other lesions are decreasing in size.  
 
Increased FDG uptake in a previously unaffected site should only be considered relapsed or progressive 
disease after confirmation with other modalities. In patients with no prior history of pulmonary 
lymphoma, new lung nodules identified by CT are mostly benign. Thus, a therapeutic decision should 
not be made solely on the basis of the PET without histologic confirmation.  
 
At least a 50% increase from nadir in the SPD of any previously involved nodes or extranodal masses, 
or in a single involved node or extranodal mass, or the size of other lesions (e.g. splenic or hepatic 
nodules). To be considered progressive disease, a lymph node or extranodal mass with a diameter of 
the short axis of less than 1.0 cm must increase by ≥ 50% and to a size of 1.5 cm x 1.5 cm or more than 
1.5 cm in the long axis.  
 
At least a 50% increase in the longest diameter of any single previously identified node or extranodal 
mass more than 1 cm in its short axis.  
 
Lesions should be PET positive if observed in a typical FDG-avid lymphoma or the lesion was PET 
positive before therapy unless the lesion is too small to be detected with current PET systems (< 1.5 cm 
in its long axis by CT).  
 
Measurable extranodal disease should be assessed in a manner similar to that for nodal disease. For 
these response criteria, the spleen is considered nodal disease. Disease that is only assessable (e.g.,

pleural effusions, bone lesions) will be recorded as present or absent only, unless, while an 
abnormality is still noted by imaging studies or physical examination, it is found to be histologically 
negative. 
 
14.3.5 Response Endpoints  
All tumor assessments will be made using Revised Response (Cheson) criteria.  
 
Pembrolizumab is expected to trigger immune-mediated responses, which require activation of the 
immune system prior to the observation of clinical responses. Such immune activation may take weeks 
to months to be evident. Some patients may experience tumor flare with objective volume increase of 
tumor lesions or other disease parameters (based on study indication, ie, hematologic malignancies) 
within 12 weeks following the start of pembrolizumab dosing. Such patients may not have had 
sufficient time to develop the required immune activation or, in some patients, tumor volume or other 
disease parameter increases may represent infiltration of lymphocytes into the original tumor or 
blood. In conventional studies, such tumor volume or relevant laboratory parameter increases during 
the first 12 weeks of the study would constitute PD and lead to discontinuation of imaging to detect 
response, thus disregarding the potential for subsequent immune-mediated clinical response.  
Therefore if at the first imaging time point (12 weeks after initiating treatment) patients demonstrate 
up to 2 new lesions, with sum of all lesions < 70% greater than baseline by SPD, or decreasing in size, 
and stable without evidence of rapid clinical deterioration, patients may be continue to be treated with 
pembrolizumab and clinically observed with imaging repeated after 1 month. If, at that time, there is 
Progression of Disease (POD) by standard Revised Response Criteria patients will be removed from 
study. For patients in whom investigators consider that tumor flare may be playing a role in the 
response seen on initial imaging, this must be documented at time of scan, and discussed with Study 
Chair. This may improve the overall assessment of the clinical activity of pembrolizumab and more 
likely capture its true potential to induce clinical responses. In regards to PFS analysis, the date of 
progression for patients who were initially considered to have tumor flare, but had further progression 
of disease (POD) on the repeat image after 1 month, will be the time of first imaging in which new 
lesions were originally detected. 
 
14.3.6 Duration of Response  
This is measured from the documented beginning of response (CR or PR) to the time of relapse. This is 
measured in responders.  
 
14.3.7 Overall Survival  
Overall survival is defined as the date of study entry to the date of death.  
 
14.3.8 Progression-free Survival 
Progression-free Survival (PFS) is defined as the time from entry onto study until lymphoma progression 
or death from any cause. PFS is often considered the preferable endpoint in lymphoma clinical trials. PFS 
reflects tumor growth and, therefore, occurs prior to the endpoint of overall survival. In addition, PFS is 
not confounded by the administration of subsequent therapy. Whether a prolongation of PFS represents 
direct clinical benefit or a surrogate for clinical benefit depends on the magnitude of the effect and the

risk-benefit ratio of the therapy under investigation. Unlike survival, the precise date of progression is 
generally unknown. It may be defined as the first date of documentation of a new lesion or enlargement 
of a previous lesion, or the date of the scheduled clinic visit immediately after radiologic assessment has 
been completed. Where there is missing information, censoring of the data may be defined as the last 
date at which progression status was adequately assessed or the first date of unscheduled new anti-
lymphoma treatment.

14.4 Events of Clinical Interest (ECI) guidance 
This appendix offers specific guidance for investigators for the management of ECI based on the 
“PEMBROLIZUMAB PROGRAM (MK-3475) EVENT OF CLINICAL INTEREST 
GUIDANCE DOCUMENT Version 5.0”.  
 
These recommendations should be seen as guidelines and the treating physician should exercise 
individual clinical judgment based on the patient. For any question of dose modification or other 
treatment options, the specific language in the protocol should be followed.  
 
The treatment guidance provides specific direction when to hold and/or discontinue pembrolizumab 
for each immune related adverse event. Of note, when the guidance states to “discontinue” 
pembrolizumab this is the permanent discontinuation of treatment with pembrolizumab. “Hold” 
means to stop treating with pembrolizumab but resumption of treatment may be considered assuming 
the patient meets the criteria for resumption of treatment.

14.4.2 Pneumonitis 
The following AE terms, if considered ≥ Grade 2, are considered ECIs and should be reported to the 
Sponsor within 24 hours of the event: 
– Pneumonitis 
– Interstitial lung disease

Version Date 01/13/2020 
– Acute interstitial pneumonitis 
 
If symptoms indicate possible new or worsening cardiac abnormalities additional testing and/or a 
cardiology consultation should be considered. All attempts should be made to rule out other causes 
such as metastatic disease, bacterial or viral infection. It is important that patients with a suspected 
diagnosis of pneumonitis be managed as per the guidance below until treatment-related pneumonitis 
is excluded. Treatment of both a potential infectious etiology and pneumonitis in parallel may be 
warranted. Management of the treatment of suspected pneumonitis with steroid treatment should 
not be delayed for a therapeutic trial of antibiotics. If an alternative diagnosis is established, the 
patient does not require management as below; however, the AE should be reported regardless of 
etiology. 
 
Course of Action 
Grade 2 events: 
– Report as ECI 
– Hold pembrolizumab. 
– Consider pulmonary consultation with bronchoscopy and biopsy/BAL. 
– Consider ID consult 
– Conduct an in person evaluation approximately twice per week 
– Consider frequent Chest X-ray as part of monitoring 
– Treat with systemic corticosteroids at a dose of 1 to 2 mg/kg/day prednisone or equivalent. 
When symptoms improve to Grade 1 or less, steroid taper should be started and continued 
over no less than 4 weeks. 
– Permanently discontinue for inability to reduce corticosteroid dose to 10 mg or less of 
prednisone or equivalent per day within 12 weeks. 
– Second episode of pneumonitis – discontinue pembrolizumab if upon re-challenge the patient 
develops a second episode of Grade 2 or higher pneumonitis. 
 
Grade 3 and 4 events: 
– Report as ECI 
– Discontinue pembrolizumab. 
– Hospitalize patient 
– Bronchoscopy with biopsy and/or BAL is recommended. 
– Immediately treat with intravenous steroids (methylprednisolone 125 mg IV). When 
symptoms improve to Grade 1 or less, a high dose oral steroid (prednisone 1 to 2 mg/kg once 
per day or dexamethasone 4 mg every 4 hours) taper should be started and continued over no 
less than 4 weeks. 
– If IV steroids followed by high dose oral steroids does not reduce initial symptoms within 48 
to 72 hours, treat with additional anti-inflammatory measures. Discontinue additional anti-
inflammatory measures upon symptom relief and initiate a prolonged steroid taper over 45 to 
60 days. If symptoms worsen during steroid reduction, initiate a retapering of steroids starting 
at a higher dose of 80 or 100 mg followed by a more prolonged taper and administer additional 
anti-inflammatory measures, as needed 
– Add prophylactic antibiotics for opportunistic infections.

– Diarrhea 
All attempts should be made to rule out other causes such as metastatic disease, bacterial or parasitic 
infection, viral gastroenteritis, or the first manifestation of an inflammatory bowel disease by 
examination for stool leukocytes, stool cultures, a Clostridium difficile titer and endoscopy. However 
the AE should be reported regardless of etiology. 
 
Course of Action

abdominal pain, mucus or blood in stool): 
– Report as ECI 
– Hold pembrolizumab. 
– Symptomatic Treatment 
– For Grade 2 diarrhea that persists for greater than 3 days, and for diarrhea with blood and/or 
mucus, 
o Consider GI consultation and endoscopy to confirm or rule out colitis 
o Administer oral corticosteroids (prednisone 1-2 mg/kg QD or equivalent) 
– When symptoms improve to Grade 1 or less, steroid taper should be started and continued 
over no less than 4 weeks. 
– Permanently discontinue for inability to reduce corticosteroid dose to 10 mg or less of 
prednisone or equivalent per day within 12 weeks. 
– If symptoms worsen or persist > 3 days treat as Grade 3 
 
Grade 3 Diarrhea/Colitis (or Grade 2 diarrhea that persists for > 1 week): 
– Report as ECI 
– Hold pembrolizumab. 
– Rule out bowel perforation. Imaging with plain films or CT can be useful.

– Permanently discontinue for inability to reduce corticosteroid dose to 10 mg or less of 
prednisone or equivalent per day within 12 weeks. 
– If IV steroids followed by high dose oral steroids does not reduce initial symptoms within 48 
to 72 hours, consider treatment with additional anti-inflammatory measures as described in the 
literature [5]. 
Discontinue additional anti-inflammatory measures upon symptom relief and initiate a 
prolonged steroid taper over 45 to 60 days. If symptoms worsen during steroid reduction, 
initiate a retapering of steroids starting at a higher dose of 80 or 100 mg followed by a more 
prolonged taper and administer additional anti-inflammatory measures as needed. 
 
Grade 4 events: 
– Report as ECI 
– Permanently discontinue pembrolizumab. 
– Manage as per Grade 3. 
 
14.4.4 Endocrine 
The following AE terms, if considered ≥Grade 3 or if ≥Grade 2 and require 
holding/discontinuation/modification of pembrolizumab dosing, are considered ECIs and should be 
reported to the Sponsor within 24 hours of the event: 
 
– Adrenal insufficiency 
– Hyperthyroidism 
– Hypophysitis 
– Hypopituitarism 
– Hypothyroidism 
– Thyroid disorder 
– Thyroiditis 
 
All attempts should be made to rule out other causes such as brain metastases, sepsis and/or infection. 
However, the AE should be reported regardless of etiology. 
 
Hypophysitis or other symptomatic endocrinopathy other than hypo- or hyperthyroidism 
 
Grade 2-4 events: 
– Report as ECI if appropriate 
– Hold pembrolizumab 
– Rule out infection and sepsis with appropriate cultures and imaging. 
– Monitor thyroid function or other hormonal level tests and serum chemistries more 
frequently until returned to baseline values. 
– Pituitary gland imaging should be considered (MRIs with gadolinium and selective cuts of the 
pituitary can show enlargement or heterogeneity and confirm the diagnosis). 
– Treat with prednisone 40 mg p.o. or equivalent per day. When symptoms improve to Grade 1 
or less, steroid taper should be started and continued over no less than 4 weeks. Replacement 
of appropriate hormones may be required as the steroid dose is tapered.

Version Date 01/13/2020 
– Permanently discontinue for inability to reduce corticosteroid dose to 10 mg or less of 
prednisone or equivalent per day within 12 weeks. 
– Hypophysitis with clinically significant adrenal insufficiency and hypotension, dehydration, 
and electrolyte abnormalities (such as hyponatremia and hyperkalemia) constitutes adrenal 
crisis. 
– Consultation with an endocrinologist may be considered. 
 
14.4.5 Hyperthyroidism and Hypothyroidism 
Thyroid disorders can occur at any time during treatment. Monitor patients for changes in thyroid 
function (at the start of treatment, periodically during treatment, and as indicated based on clinical 
evaluation) and for clinical signs and symptoms of thyroid disorders. 
 
Grade 2 hyperthyroidism, Grade 2-4 hypothyroidism events: 
– Report as ECI if appropriate (see Table 1) 
– Monitor thyroid function or other hormonal level tests and serum chemistries more 
frequently until returned to baseline values. 
– Thyroid hormone and/or steroid replacement therapy to manage adrenal insufficiency. 
– Therapy with pembrolizumab can be continued while treatment for the thyroid disorder is 
instituted. 
– In hyperthyroidism, non-selective beta-blockers (e.g. propranolol) are suggested as initial 
therapy. 
– In hypothyroidism, thyroid hormone replacement therapy, with levothyroxine or

Version Date 01/13/2020 
– Type I diabetes mellitus (T1DM), if new onset, including diabetic ketoacidosis (DKA) 
– Grade 3 or higher hyperglycemia, if associated with ketosis (ketonuria) or metabolic acidosis 
(DKA). Immune-mediated diabetes may present as new onset of Type 1 diabetes or an abrupt 
worsening of preexisting diabetes associated with laboratorial evidence of beta cell failure. All 
attempts should be made to rule out other causes such as type 2 diabetes mellitus (T2DM), 
T2DM decompensation, steroid-induced diabetes, physiologic stress-induced diabetes, or 
poorly controlled pre-existing diabetes (either T1DM or T2DM), but events meeting the above 
criteria should be reported as ECIs regardless of etiology. The patients may present with 
hyperglycemia (abrupt onset or abrupt decompensation) with clinical evidence of diabetic 
ketoacidosis or laboratory evidence of insulin deficiency, such as ketonuria, laboratory evidence 
of metabolic acidosis, or low or undetected c-peptide. 
 
Course of Action 
T1DM should be immediately treated with insulin. 
 
T1DM or Grade 3-4 Hyperglycemia events: 
- Report as ECI if appropriate (see Table 1) 
- Hold pembrolizumab for new onset Type 1 diabetes mellitus or Grade 3-4 hyperglycemia 
associated with evidence of beta cell failure, and resume pembrolizumab when patients are 
clinically and metabolically stable. 
- Insulin replacement therapy is recommended for Type I diabetes mellitus and for Grade 3-4 
hyperglycemia associated with metabolic acidosis or ketonuria. 
- Evaluate patients with serum glucose and a metabolic panel, urine ketones, glycosylated 
hemoglobin, and C-peptide. 
- Consultation with an Endocrinologist is recommended. 
- Consider local testing for islet cell antibodies and antibodies to GAD, IA-2, ZnT8, and insulin 
may be obtained. 
 
14.4.7 Hematologic 
The following AE term, if considered Grade ≥3 or requiring dose modification or use of systemic 
steroids to treat the AE, are considered an ECI and should be reported to the Sponsor within 24 hours 
of the event:

– Disseminated Intravascular Coagulation (DIC) 
– Haemolytic Uraemic Syndrome (HUS) 
– Idiopathic (or immune) Thrombocytopenia Purpura (ITP) 
– Thrombotic Thrombocytopenic Purpura (TTP) 
– Any Grade 4 anemia regardless of underlying mechanism 
 
All attempts should be made to rule out other causes such as metastases, sepsis and/or infection. 
Relevant diagnostic studies such as peripheral blood smear, reticulocyte count, LDH, haptoglobin, bone 
marrow biopsy or Coomb’s test, etc., should be considered to confirm the diagnosis. However the AE 
should be reported regardless of etiology.

done even if you do not join the research study.  If you have had some of them recently, they may 
not need to be repeated.  This will be up to your study doctor. 
 
 
Physical exam which will include height, weight and vital signs  
 
You will be asked questions about your medical history and daily activities 
 
You will be asked about the medicines you are taking or have recently taken (over-the-
counter medications, supplements, prescription medications or illegal drugs) 
 
You will be asked about any side-effects you may be experiencing   
 
You will be asked to provide a tumor sample from a previous biopsy or surgical procedure 
if available. You will also be asked to provide a newly obtained tumor biopsy tissue sample   
o This sample will be tested to ensure it can be evaluated for the specific biomarkers 
to be tested in this study.  Your sample may also be used for the analysis of 
additional biomarkers to investigate ways that the study drug does or does not 
work to shrink tumors 
o Other additional biomarkers which may impact how individuals respond to the 
study drug may also be analyzed   
o Any sample left over after these tests will be stored for future research if you 
consent to the optional Future Biomedical Research (FBR) sub-study 
 
Routine blood tests (about 1 tablespoon) 
o These samples will be used to check blood counts, kidney and liver function, 
thyroid function and the levels of certain enzymes and minerals normally found in 
the blood 
 
Blood (1 teaspoon) to test how fast your blood takes to clot 
 
A PET/CT scan or CT scan of your tumor 
o A PET scan requires an injection of a radioactive material into a vein and produces 
3-D images to see how your cells work.  
o A CT scan is a computerized x-ray that gives your study doctor pictures of the 
inside of your body 
o A PET/CT scan combines the two scans to allow doctors to see the location and 
function of cells within the body 
 
Urine test 
 
Blood pregnancy test (1 teaspoon), if you are a female and able to become pregnant 
 
We will perform a blood test to check the presence of a viral infection (CMV) 
 
During the research study 
 
Study Treatment 
 
This study has two cohorts, cohort 1 and cohort 2. Patients in cohort 1 will be treated with 
pembrolizumab alone while patients in cohort 2 will be treated with the combination of 


IRB # 15-1020 
Page 3 of 16  
 
 
Protocol version date: 01/13/2020 
pembrolizumab and copanlisib. Cohort 1 is already completed and therefore you will be enrolled 
in cohort 2.  
 
Cohort 2: This cohort has two phases of treatment, phase 1 and phase 2. In this cohort you will 
be asked to take Bactrim drug either one tablet daily (single strength) or three times a week 
(double strength) to prevent infections. This cohort has an induction phase prior to treatment 
cycles where patients will be infused with one of the drugs, copanlisib, twice- on day -21 and day 
-14 of 21 day period (called day -1 to -21 before treatment with the combination drugs) and blood 
will be collected prior to the first dose and a week after the second dose of the drug (day -21, prior 
to infusion, and day -7). After the 21 days long induction phase, treatment with combination of 
copanlisib and pembrolizumab will begin and administered in a cyclical manner. 
 
Phase 1: Phase 1 portion is to determine the dose of copanlisib that is safe and tolerable in 
combination with pembrolizumab. If you are in this cohort, you will be administered a fixed dose 
of pembrolizumab (200 mg on day 1 of each cycle) and the dose of copanlisib will depend on the 
dose level at which you enter the study. It could either be 45 mg on day 1 or 45 mg on day 1 and 
day 8 or 60 mg on day 1 or day 8 of each cycle. Each cycle is 21 days long.  
 
Phase 2: If you are enrolled in phase II portion you will be administered pembrolizumab 200 mg 
on day 1 of each cycle and copanlisib will be administered as determined to be safe and tolerable 
from phase 1 position. Each cycle is 21 days long.  
 
Tests and Procedures 
 
If the exams, tests and procedures show that you can be in the research study, and you choose 
to take part, then you will need the following tests and procedures.  They are part of regular cancer 
care, but may be done more often because you are in this research study. 
 
 
Physical exam which will include weight and vital signs  
 
We will ask you about your ability to perform daily activities 
 
We will ask you about the medicines you are taking or have recently taken (over-the-
counter medications, supplements, prescription medications or illegal drugs).  
 
We will ask you about all the side-effects that you may be experiencing  
 
Routine blood tests (about 1 tablespoon) 
 
Research blood tests (about 2-3 teaspoons) 
o These samples will be used to discover ways that the study drug does or does not 
work to shrink tumors 
o Other additional biomarkers which may impact how individuals respond to the 
study drug may also be studied 
 
A blood sample will be collected for genetic research 
o Your blood sample contains genes, which are made up of DNA (deoxyribonucleic 
acid) and which serve as the "instruction book" for the cells that make up our 
bodies  
o Genetic research is the study of DNA variation.  Variation in your DNA can affect 
the way you respond to drug treatments   
o The Sponsor will look at variation in your DNA.  Your DNA will be used to 
understand how genetics affect response to the treatment(s) administered

weeks for up to two years or documentation of progression of your disease, whichever 
happens earlier, about every 26 weeks for the third year, and then about every 3 to 6 
months for the rest of your life or until the study ends.   
 
If your cancer gets worse or you start a new treatment for your cancer, we would like to 
contact you by telephone about every 12 weeks for three years.  After the third year, we 
would like to contact you about every 6 months.

How long will you be in the research study? 
 
You may receive treatment with pembrolizumab and copanlisib for up to 2 years or until your 
disease gets worse, whichever happens earlier.   
 
Can you stop being in the research study? 
 
Yes. Your participation in this research is completely voluntary. If you agree to participate now 
and change your mind later, you may withdraw at any time.   Tell the study doctor if you are 
thinking about stopping or decide to stop.  He or she will tell you how to stop safely and will discuss 
with you options for withdrawal such as continuing to provide further data collection from routine 
medical care.   
 
Can you be removed from this research study? 
 
The study doctor may stop you from taking part in this research study at any time if he/she 
believes it is in your best interest; if you do not follow the research study rules; or if you suffer 
study related injuries; or if the research study is stopped. 
 
What side effects or risks can you expect from being in the research study? 
 
You may have side effects while on the research study. Everyone taking part in the research study 
will be watched carefully for any side effects. However, doctors don't know all the side effects that 
may happen. Side effects may be mild or very serious. Your health care team may give you 
medicines to help lessen side effects. Many side effects go away soon after you stop taking the 
pembrolizumab and/or copanlisib. In some cases, side effects can be serious, long lasting, or may 
never go away. 
 
You should talk to your study doctor about any side effects that you have while taking part in the 
research study.

It is possible that if your blood sugar increases (hyperglycemia), glucose lowering medications 
(insulin and/or an oral medication) or even hospitalization may be required. 
 
If you experience respiratory symptoms such as cough, shortness of breath, or fever, it may be 
caused by pneumonitis or respiratory infections (such as pneumonia or lung infections) in some 
cases. These conditions usually respond well to therapy, but may become life-threatening or fatal 
if not promptly treated. Please contact your doctor for further advice if you experience any of these 
symptoms.  
Opportunistic Infections: 
During treatment with copanlisib you may develop bacterial or viral infection. In order to prevent 
developing of such infections additional tests will be performed on a regular basis. Your physician 
may advise using prophylactic treatment for this kind of infection at any time during treatment with 
copanlisib. 
As the study drug is under development, there may be side effects, including allergies that are 
not yet known. Therefore, you must notify your study doctor of any new symptoms that you may 
have whether or not you think they are caused by the study drug. 
You may experience some of these side effects, which are usually temporary and manageable. 
However, this study may include risks that are yet unknown and may cause serious problems or 
even death. 
Radiation Risk for Diagnostic Imaging 
 
It is unlikely that there will be any harmful effects from the radiation exposure you will 
receive from participating in this study 
 
At high levels of exposure, scientists agree that radiation can cause cancer 
 
At low exposure levels most scientists agree that the risk, if any, is very low.  You will have 
low levels of radiation exposure with diagnostic imaging procedures 
 
Risks from exposure to radiation may accumulate over a lifetime 
 
CT Scan: CT scans are used to create images of internal bones and organs using radiation   
o High dose radiation is known to produce cancer cells.  The effect of exposure to 
radiation adds up over a lifetime   
o The amount of radiation exposure involved in this trial will not be significantly 
greater than for subjects with your disease who do not take part in the trial.   
o The contrast solution that may be given for a CT scan may cause an allergic 
reaction (rare)  
 
Severe allergic reactions can be life threatening   
 
CT contrast solution can cause kidney damage, especially if you are 
diabetic, dehydrated (lost body water) or elderly

Genetic Information Nondiscrimination Act (GINA) 
 
A Federal law, called the Genetic Information Nondiscrimination Act (GINA), generally makes it 
illegal for health insurance companies, group health plans, and most employers to discriminate 
against you based on your genetic information. This law generally will protect you in the following 
ways: 
Health insurance companies and group health plans may not request your genetic information 
that we get from this research. 
Health insurance companies and group health plans may not use your genetic information when 
making decisions regarding your eligibility or premiums. 
Employers with 15 or more employees may not use your genetic information that we get from this 
research when making a decision to hire, promote, or fire you or when setting the terms of your 
employment. 
All health insurance companies and group health plans must follow this law. All employers with 
15 or more employees must follow this law.  Be aware that this Federal law does not protect you 
against genetic discrimination by companies that sell life insurance, disability insurance, or long-
term care insurance. 
 
 
Are there benefits to taking part in the study? 
 
Taking part in this study may or may not make your health better. While doctors hope the 
treatment will be more useful against cancer compared to the usual treatment, there is no proof 
of this yet. We do know that the information from this study will help doctors learn more about 
pembrolizumab and copanlisib as a treatment for cancer. This information could help future 
cancer patients. The sponsor does not intend to provide you with ownership or financial benefits 
that may result from this study. 
 
What other choices do you have if you do not take part in this research study? 
 
Your other choices may include: 
 
Getting treatment or care for your cancer without being in a study  
 
Taking part in another study  
 
Getting no treatment  
 
Getting comfort care, also called palliative care. This type of care helps reduce pain, 
tiredness, appetite problems and other problems caused by the cancer.  It does not treat 
the cancer directly, but instead tries to improve how you feel. Comfort care tries to keep 
you as active and comfortable as possible 
 
Talk to your doctor about your choices before you decide if you will take part in this study.

What are the costs? 
  
You and/or your health plan/insurance company will need to pay for some or all of the costs of 
treating your cancer in this study. Some health plans will not pay these costs for people taking 
part in studies. Check with your health plan or insurance company to find out what they will pay 
for. Taking part in this study may or may not cost your insurance company more than the cost of 
getting regular cancer treatment. 
 
Merck will supply pembrolizumab and Bayer will supply copanlisib at no charge while you take 
part in this study. However, the cost of getting the pembrolizumab and copanlisib ready and giving 
it to you will not be covered, so you or your insurance company may have to pay for this. 
 
Study related tests will be provided at no cost to you. 
 
If your insurance will not pay for medicines you may need to help with side effects, you may have 
to pay for them.
