This placebo-controlled study will investigate the effect of tocilizumab (an anti-interleukin-6 receptor antibody) on symptom burden, physical functioning, and quality of life in patients with chronic pancreatitis.
Recent independent research has emphasized the crucial role of immune cell infiltration and its interaction with pancreatic stellate cells in driving the inflammatory process and fibrogenesis in chronic pancreatitis (CP). The cytokine Interleukin 6 (IL-6) has been identified as a key mediator in this process, and preclinical studies have indicated that inhibiting IL-6 signaling can lead to favorable therapeutic outcomes. Consequently, targeting IL-6 signaling therapeutically holds great promise as a disease-modifying treatment for CP.
Until now, there have been no placebo-controlled trials in humans to test immune-modulating treatments for CP. However, there have been some promising results in preclinical studies. For example, administering an anti-IL-6 receptor antibody to an animal model of CP reduced pancreatitis-related pain, indicating a potential therapeutic effect. Blocking IL-6 signaling in an in-silico model of CP was also shown to have disease-modifying effects. Recent anecdotal evidence indicates that using tocilizumab to treat patients with COVID-19 and concomitant pancreatitis can decrease inflammation and pain in the pancreas. Additionally, blocking IL-6 signaling has been demonstrated to have anti-fibrotic effects in patients with systemic sclerosis. Taken together, these findings suggest that targeting IL-6 signaling could be a promising approach for reducing inflammation and fibrogenesis in CP. Tocilizumab (RoActemra) is an anti-IL-6 receptor antibody currently used to treat several inflammatory diseases.
Objectives:
The investigators hypothesize that treatment with tocilizumab, compared with a placebo, will reduce symptom burden (CP-related pain) and improve physical functioning and quality of life in patients with CP. In addition, the investigators hypothesize that the clinical effects will be linked to a decrease in pancreatic inflammation and fibrosis as well as systemic inflammation. The investigators also hypothesize that the pain-relieving effect of tocilizumab will lead to the normalization of pain processing in CP patients. To test these hypotheses, the project is organized into four sub-studies.
Sub-study 1 (main study - randomized placebo-controlled trial): The objective of sub-study 1 is to conduct an investigator-initiated phase 2b double-blinded, placebo-controlled, randomized clinical trial to investigate the clinical effect of tocilizumab on patient-reported outcomes.
Sub-study 2 (inflammatory biomarkers): The objective of sub-study 2 is to investigate the effects of tocilizumab on systemic inflammation using blood-based immune and fibrosis markers.
Sub-study 3 (quantitative imaging biomarkers): The objective of sub-study 3 is to investigate the effect of tocilizumab on pancreatic inflammation and fibrosis using Magnetic Resonance Imaging (MRI) of the pancreas.
Sub-study 4 (pain processing): The objective of sub-study 4 is to investigate the effect of tocilizumab on pain processing using Pancreatic Quantitative Sensory Testing (P-QST) and electrophysiological methods (EEG and ECG).

| P-QST: PinPrick (Temporal summation) | The pancreatic quantitative sensory testing (P-QST) is used to characterize pain processing and comprises different experimental pain stimuli: PinPrick test: A pinprick stimulator 256 mN (MRC Systems GmbH, Germany) will be used to perform the pinprick test. The patient is asked to rate the pain sensitisation using the VAS score after a single pinprick stimulus and after ten repetitive stimuli (applied with an interstimulus interval of 1 second). Two test areas are assessed: the dominant forearm and the anterior TH10 dermatome. The score is reported on a VAS score from 0 to 10. Higher scores indicate higher pain tolerance. | The intervention period is 24 weeks (performed at weeks 0 and 24) |
| P-QST: Pain Pressure thresholds | The P-QST is used to characterize pain processing and comprises different experimental pain stimuli: Pain pressure test: Pressure algometry is performed with a handheld pressure algometer (Type2, Somedic production AB, Sweden) and performed in four dermatomes and five locations: C5 (the clavicle), TH10 (the back and abdomen), L1 (the anterior superior iliac spine), and L4 (straight thigh). The probe has a surface area of 1cm2. Pressure will be increased at a rate of 30 kPa/sec until prespecified thresholds (i.e., pain detection threshold (PDT) and pain tolerance threshold (PTT)) are reached. The assessment parameters are the imposed pressure (kPa) at the PDT and PTT. | The intervention period is 24 weeks (performed at weeks 0 and 24) |
| P-QST: Cold Pressor | The P-QST is used to characterize pain processing and comprises different experimental pain stimuli: Cold pressor test: The patient's hand is immersed in cold water (approximately two degrees Celsius) for 120 seconds. At 40, 80, and 120 seconds, the patient is asked to rate the pain sensation using a VAS score. If the patient cannot keep their hand in the water for 120 seconds, the duration is noted, and the VAS score at the time they withdraw their hand is used as the maximum score. The assessment parameters are the cold pressor endurance time (seconds) and the evoked pain responses on a visual analog scale (VAS) score, 0 = no pain and 10 = worst pain imaginable. Lower values indicate higher pain tolerance. | The intervention period is 24 weeks (performed at weeks 0 and 24) |
| P-QST: Conditioned Pain Threshold | The P-QST is used to characterize pain processing and comprises different experimental pain stimuli: Conditioned pain modulation test is conducted using a pain pressure algometer, and the PTT is assessed at 15 cm above the patella in the L4 dermatome on the nondominant side before and after the cold pressor test is performed. The imposed pain pressure tolerance threshold is reported as kPa, with a minimum of 0, and no upper limit. Higher scores indicate higher pain tolerance. | The intervention period is 24 weeks (performed at weeks 0 and 24) |
| Electroencephalography (EEG) analysis | While performing the P-QST, the investigators measure EEG and ECG before and after the cold pressor test. A standard EEG electrode Cap Kit (EEG Electrode Cap Kit - OpenBCI Online Store) with ten electrodes is employed for these measurements.The Texas Instrument ADS1299 biopotential measurements system will be used for EEG and ECG recordings. This system is already being used in mobile brain-computer interfaces, and its signals are comparable to those of standard systems that can work in hospital settings. The EEG signals are transmitted wirelessly to an Android mobile telephone and stored for further processing. The results will be used to model connectivity between brain centres as well as the dominating centres of the brain. EEG power will be assessed in the Delta, Theta, Alpha, Beta, and Gamma bands between 1 and 70 Hertz. Finally, inverse modelling will be conducted to explore the dominating centres of brain activity. | The intervention period is 24 weeks (assessed at weeks 0 and 24) |
| Electrocardiographic (ECG) frequency domain | Four conventional ECG electrodes (Neurolink 700) is employed for these measurements.

Frequency domains of heart variablity will be assessed using ECG,this involve Fast Fourier transformation of the Blackman Harris window included very low frequency (VLF), low frequency (LF), high frequency (HF), total power (TP), and the ratios LF/HF. | The intervention period is 24 weeks (assessed at weeks 0 and 24) |
| ECG time domain | Four conventional ECG electrodes (Neurolink 700) is employed for these measurements.
