About this study
Official title: CRSPA: Phase I/II Study of CM4620 to Reduce the Severity of Pancreatitis Due to Asparaginase
This is a phase I/II clinical trial assessing the tolerability and efficacy of CM4620 in children and young adults with acute pancreatitis caused by asparaginase. The tolerability of CM4620 when given to patients receiving frontline chemotherapy will be determined. The effectiveness in reducing the severity of pancreatitis will be estimated.
Primary Objectives
Read more
To assess the safety of CM4620 administration in children and young adults with asparaginase associated pancreatitis (AAP).
To profile dose-limiting toxicities and responses of the patients treated in the dose-finding phase.
To estimate the efficacy of CM4620 to prevent pseudocyst or necrotizing pancreatitis in children with AAP.
Secondary Objectives
To determine the effect of CM4620 on the incidence of severe pancreatitis
To determine the effect of CM4620 on the incidence of Systemic Inflammatory Response Syndrome (SIRS).
Read the detailed description
This is an open label safety and efficacy evaluation with comparison of toxicity to a historical control population (TOTXVI). There will be 3 cohorts of patients enrolled, and the dose for each cohort will be determined based on the toxicities experienced in the ongoing and prior cohorts.
An initial 9 patients (cohort 1) will be enrolled and will receive dose level 1 and monitored for toxicity. If the therapy is well tolerated, 6 patients (cohort 2) will be treated at dose level 2. Subsequent enrollment of 9 patients (cohort 3) will be at either dose level 1 or 2 based on tolerability. The keyboard design will be used to determine the dosing for cohorts 2 and 3. Additional patients will be enrolled at the recommended phase II dose (RP2D) until a total of 24 patients have been treated at that dose, including any treated during the dose-finding phase.
CM4620 will be given days 1-4 as an IV infusion beginning within 36 hours of the onset of acute pancreatitis associated abdominal pain and within 8 hours of enrollment. For patients with prior abdominal pain or in those unable to communicate the location/characteristic of their pain, a change in the characteristic of the pain or new enzyme elevation/imaging findings after previously normal studies will determine the timing of onset of pancreatitis.
Patients will be followed for about 4 months after treatment.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing CM4620 in people with Acute Pancreatitis, run by St. Jude Children's Research Hospital at 3 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 3 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 3 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Seth E. Karol, MD (888-226-4343, referralinfo@stjude.org), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The number of CTCAE grade 3-5 events (time frame: Within 28 days of receiving the medication). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Jun 2026.
