Biomarkers in Urothelial Cancer Patients Treated With Pembrolizumab (RESPONDER)
Biomarker Discovery Study to Identify Patients With Advanced Urothelial Cancer Benefitting From Pembrolizumab Treatment
In the RESPONDER study, the role of the immune evasive mechanisms combined with genomic characterization will be explored in urothelial cancer patients treated with second-line treatment with pembrolizumab.
Combined profiling of immune and molecular status is novel and may contribute to improved patient stratification and provide rationale for future treatment strategies containing pembrolizumab.

Detailed Description
Antibodies that target the crosstalk between immune and cancer cells by inhibiting programmed death 1 (PD-1, Pembrolizumab and Durvalumab) or programmed death-ligand 1 (PD-L1, Atezolizumab) have shown promising results as second-line treatments in phase II studies with response rates of about 30%.
Although urothelial cancer is prone to immune checkpoint blockade, better understanding of the underlying mechanisms is necessary to improve patient selection. The efficacy of immune checkpoint inhibitors in urothelial cancer may be affected by both tumor specific and environmental factors. In order to improve the efficacy of immunotherapy in urothelial cancer, drivers of local immune suppression need to be identified.
In this prospective translational multicenter study, clinical data, peripheral blood and sequential tumor biopsies are collected from urothelial cancer patients treated with second-line treatment with pembrolizumab to identify the role of immune evasive mechanisms combined with genomic characterization. A pre-treatment tumor biopsy and blood sample will be obtained and subsequently whole genome sequencing and whole genome RNA sequencing is performed. Both tumor tissue as well as peripheral blood will be investigated for immune and molecular profiling. A biopsy will also be taken after start of treatment (at 6 weeks) and at progression (optional)
For future research projects, longitudinal blood samples will be collected for isolation of immune cells, cytokine/chemo-attractants and circulating tumor DNA (ctDNA).

- Note: If subject received major surgery, they must have recovered adequately from the toxicity and/or complications from the intervention prior to starting therapy.
- Has a known additional malignancy that is progressing or requires active treatment Exceptions include basal cell carcinoma of the skin or squamous cell carcinoma of the skin that has undergone potentially curative therapy or in situ cervical cancer.
- Has known active central nervous system (CNS) metastases and/or carcinomatous meningitis. Subjects with previously treated brain metastases may participate provided they are stable (without evidence of progression by imaging for at least four weeks prior to the first dose of trial treatment and any neurologic symptoms have returned to baseline), have no evidence of new or enlarging brain metastases, and are not using high dose steroids (defined as >=; 20 mg prednisone or equivalent per day) for at least 7 days prior to trial treatment. This exception does not include carcinomatous meningitis which is excluded regardless of clinical stability.
- Has active autoimmune disease that has required systemic treatment in the past 2 years (i.e. with use of disease modifying agents, corticosteroids or immunosuppressive drugs). Replacement therapy (eg., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment.
- Has known history of, or any evidence of active, (non-infectious) pneumonitis that required steroids, evidence of interstitial lung disease or active, non-infectious pneumonitis.
- Has an active infection requiring systemic therapy.
- Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the trial, interfere with the subjects participation for the full duration of the trial, or is not in the best interest of the subject to participate, in the opinion of the treating investigator.
- Has known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial.
- Is pregnant or breastfeeding, or expecting to conceive or father children within the projected duration of the trial, starting with the prescreening or screening visit through 120 days after the last dose of trial treatment.

Has a known history ofor is positive for hepatitis B (hepatitis B surface antigen [HBsAg] reactive) or hepatitis C (hepatitis C virus [HCV] RNA [qualitative] is detected). Note: Without known history, testing needs to be performed to determine eligibility.
Hepatitis C antibody (Ab) testing is allowed for screening purposes in countries where HCV RNA is not part of standard of care.

Measure Description |
Time Frame |
---|---|---|
Biomarkers in patients with clinical benefit
Time Frame: End of study (pembrolizumab will be given for a maximum of 24 months), which is within 3 years after start of inclusion
|
Peripheral blood and sequential tumor biopsies are collected before start of treatment, during treatment, and (optionally) at progression. Immune profiling using in situ multiplex immunofluorescence will be performed to identify tumor epithelial and stromal cells, effector immune cells, T cell co-inhibition, T cell recruitment and immune-suppressive cells. Furthermore, serum samples will be assessed for levels of cytokines/chemoattractants. Finally, longitudinal blood samples will be collected for isolation of immune cells, cytokine/chemo-attractants and ctDNA. A qualified pathologist will determine tumor cell percentage in the obtained biopsies. DNA will be obtained from both cancer cells (biopsy tissue) and normal white blood cells (peripheral blood) and will be submitted for whole genome sequencing. The obtained data will contribute to identifying potential biomarkers in patients with clinical benefit. |

Time Frame |

Mechanisms of primary and acquired resistance to pembrolizumab
Time Frame: End of study (pembrolizumab will be given for a maximum of 24 months), which is anticipated to be within 3 years after start inclusion.
|
Combined profiling of immune and molecular status (as described in outcome 1) during treatment and at disease progression will reveal different mechanisms by which urothelial cancer evades pembrolizumab. Additional bio-informatic analyses will be done to detect the somatic structural variants and copy number changes. The genome data will be used to explore potential correlations between specific pathway aberrations, total number of somatic variants and pattern of mutational load characteristic of the DNA mutational agent and clinical outcome. Moreover, we will perform whole genome RNA sequencing, an essential part of the genomic analysis to identify tumor specific neo-antigens. The obtained data will contribute to identifying mechanisms of primary and acquired resistance to pembrolizumab. |
End of study (pembrolizumab will be given for a maximum of 24 months), which is anticipated to be within 3 years after start inclusion.
|
Correlations between biomarkers and clinical activity
Time Frame: End of study (pembrolizumab will be given for a maximum of 24 months), which is anticipated to be within 3 years after start inclusion.
|
The following definitions and response evaluation criteria will be used to assess potential correlation: immune related response criteria (irRC), duration of response according to RECIST and irRC, duration of clinical benefit (CR-complete response/PR-partial response/SD-stable disease) according to RECIST and irRC, progression-free survival, and overall survival. By combining the data from the profiling of immune and molecular status (as described in outcome 1) with the additional data from bio-informatic analyses (as described in outcome 2) and the clinical activity (as described above), correlations between biomarkers and clinical activity can be identified. |
End of study (pembrolizumab will be given for a maximum of 24 months), which is anticipated to be within 3 years after start inclusion.
