Parts A (Single Ascending Dose Study) and B (Multiple Ascending Dose Study)
- Healthy male and female, non-smoking, subjects between the ages of 18 and 55 years, inclusive, at the time of Screening. In each cohort, at least 2 male subjects and 2 female subjects should be enrolled.
Appropriate general health, as determined by an experienced physician based on a medical evaluation including detailed medical history, clinical laboratory tests, vital signs, 12-lead ECG, and full physical examination (and neurological assessment).
Part C (Proof-of-Concept Study)
- Male and female subjects between the ages of 18 and 75 years (inclusive) who have undergone total or partial pancreatectomy or have an established diagnosis of CP, as confirmed by fecal pancreatic elastase-1 <100 μg/g in formed stools within 12 months of the Screening visit.
- Subjects with clinically well controlled EPI under the regular use of PERT (remission or adequate improvement of steatorrhea on PERT), as determined by an experienced physician based on a medical evaluation including detailed medical history, clinical laboratory tests, vital signs, 12-lead ECG, and full physical examination (and neurological assessment).
- 150min percentage 13CO2 excretion rate <4.4% dose/h using the Pancreo-Lip breath test at Screening.
Exclusion Criteria:
All subjects
- Female subject who has been pregnant within the 6 months prior to Screening or breastfeeding within the 3 months prior to Screening.
- Treatment with any antiplatelet and/or anticoagulant medication, except low-dose aspirin.
- Evidence or history of specific food intolerance. Examples include gluten intolerance, lactose intolerance, or dairy food intolerance or any food/ingredient included in the standard breakfast provided at the study site.
- A positive result, on Screening, for serum hepatitis B surface antigen, hepatitis A virus antibodies, hepatitis C virus antibodies or antibodies to human immunodeficiency virus type 1 and/or type 2.
- Known active infection with COVID-19, or a suspected infection with severe acute respiratory syndrome coronavirus-2 [SARS-CoV-2]).
- Chronic alcoholic intoxication that would preclude compliance with the study procedures.
- Habitual use of nicotine products or smoking within 3 months (>10 cigarettes per day) prior to Screening, and/or unwilling to refrain from smoking during the confinement period. Nicotine replacement therapy is allowed during the study.
- Drug addiction that would preclude participation and compliance with study procedures.
- Subject has a pulse rate <40 or >100 bpm; mean systolic blood pressure (SBP) >150 mmHg; mean diastolic blood pressure (DBP) >95 mmHg at Screening. Repeat measurements are allowed at the discretion of the Investigator.
- Subject has any clinically significant abnormalities at Screening in rhythm, conduction or morphology of the resting ECG and any clinically significant abnormalities in the 12-lead ECG, as considered by the Investigator, that may interfere with the interpretation of QTc interval changes including abnormal ST-T wave morphology.
- Subject has prolonged QTcF >450 msec for male subjects or >470 msec for female subjects or a family history of prolonged QT syndrome, at Screening.
- Plasma donation within the 14 days prior to the first dose of IP or any whole blood donation/significant blood loss >500 mL during the 3 months prior to the first dose of IP.
- Treatment with any investigational drug or device/treatment within the 30 days or 5 half-lives of the drug (whichever is longer) prior to the administration of IP.
Known allergy or adverse reaction history to any component of the CDX-7108 oral dose formulation.
Part A (Single Ascending Dose Study) and Part B (Multiple Ascending Dose Study)
- Evidence or history of clinically significant hematological, renal, endocrine, pulmonary, cardiovascular, hepatic, psychiatric, neurologic, or allergic disease (including drug allergies, but excluding untreated, asymptomatic, seasonal allergies and childhood asthma) at time of Screening or IP administration, that in the opinion of the Investigator may put the subject at greater safety risk, influence response to study drug, or interfere with study assessments.
- Current or chronic history of GI disorders or conditions interfering with normal GI anatomy or function. Examples include GI bypass surgery, partial or total gastrectomy, gastric band surgery, major (>1 m) small bowel resection, vagotomy, malabsorption, Crohn's disease, ulcerative colitis, irritable bowel syndrome, celiac sprue, and small intestinal bacterial overgrowth.
- A positive Screening test for use of drugs (amphetamines, cocaine, marijuana, opiates, barbiturates, benzodiazepines, methadone, and methamphetamines) and alcohol (breath test). However, there is the option to re-screen once during the Screening period at the discretion of the Investigator or delegate in the case of a positive result at Screening for a prescribed medication, eg, codeine.
- Subject has any clinically significant abnormalities in hematology, coagulation, clinical chemistry, or urinalysis at Screening as judged by the Investigator, including aspartate aminotransferase (AST) or ALT >1.5 times above the ULN. Repeat measurements are allowed at the discretion of the Investigator.
Use of any prescribed or nonprescribed medication in the 2 weeks preceding the first dose of IP. EXCEPTION: Subjects who have received approved vaccines (including approved COVID-19 vaccines) may be allowed if these vaccines are taken no less than 72 hours prior to the IP dose at the discretion of the Investigator.
Part C (Proof-of-Concept Study)
- Evidence or history of clinically significant hematological, renal, endocrine, pulmonary, cardiovascular, hepatic, psychiatric, neurologic, or allergic disease (including drug allergies, but excluding untreated, asymptomatic, seasonal allergies and childhood asthma) at time of Screening or IP administration, that in the opinion of the Investigator may put the subject at greater safety risk, influence response to study drug, or interfere with study assessments. NOTE: Subjects with treated diabetes secondary to CP or pancreatectomy are allowed.
- Subject has any clinically significant abnormalities in hematology, coagulation, clinical chemistry, or urinalysis at Screening as judged by the Investigator, including AST or ALT >1.5 times above the ULN, or cholesterol or triglycerides >400 mg/dL. Repeat measurements are allowed at the discretion of the Investigator.
- Current or chronic history of GI disorders or conditions interfering with normal GI anatomy or motility, with the exception of pancreatic insufficiency due to pancreatectomy, including pancreaticoduodenectomy, or CP
Use of any prescribed or nonprescribed medication potentially interfering with gastric pH, intestinal motility, or fat absorption, including herbal and dietary supplements and antacids; these medications shall be stopped for a minimum of 5 times their half-life before IP administration if, in the opinion of the Investigator, this does not represent a risk for the subject's wellbeing. EXCEPTIONS:
Histamine H2 receptor antagonists, PPI, insulin, analgesics, and chronic pain medications.
Oral contraceptives, paracetamol, or multivitamins. Subjects who have received approved vaccines (including approved COVID-19 vaccines) may be allowed if these vaccines are taken no less than 72 hours prior to the IP dose at the discretion of the Investigator.
