Single Arm Pilot Trial of Letermovir for CMV Prophy in CAR T Cell
- Registration Number
- NCT06575374
- Lead Sponsor
- M.D. Anderson Cancer Center
- Brief Summary
The goal of this clinical research study is to learn if a drug called Letermovir can help to prevent CMV reactivation.
- Detailed Description
Primary Objective:
Estimate the probabilities at days d = +28 and +98 following CAR T cell infusion, among patients alive at the day of evaluation, of CMV reactivation in CMV seropositive patients receiving letermovir for CMV prophylaxis after standard of care (SOC) axicabtagene ciloleucel (AXI-CEL) therapy, using the cutoff CMV DNA qPCR \> c for c = 400 and 1000 IU/mL to define CMV reactivation, for a total of four (d, c) combinations.
Secondary Objectives:
Estimate overall survival probabilities at days+28, +98, and +364 following CAR T cell infusion of CMV seropositive patients receiving letermovir for CMV prophylaxis after SOC AXI-CEL therapy.
Describe the tolerability of letermovir during the period of CMV prophylaxis after SOC AXI-CEL therapy in CMV seropositive patients at high risk for CMV reactivation.
Recruitment & Eligibility
- Status
- RECRUITING
- Sex
- All
- Target Recruitment
- 36
- Age ≥ 18 years of age.
- Have an ECOG performance status of 0 or 1.
- The participant must be scheduled for SOC AXI-CEL.
- The participant must be seropositive for CMV (defined as having anti-CMV IgG antibodies)
- Creatinine clearance > 10 mL/min
- Child Pugh class A or B if liver disease is present.
- Participants of child-bearing potential must agree to use adequate contraceptive methods (e.g., hormonal or barrier method of birth control; abstinence) prior to study entry. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform the treating physician immediately.
- Participant must understand the investigational nature of this study and sign an Institutional Review Board approved written informed consent form prior to receiving any study related procedure.
- Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection not responding to treatment, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
- Female participants who are pregnant or breastfeeding.
- Unwilling or unable to follow protocol requirements.
- Planned to receive any other anti-CMV therapy such as high dose acyclovir (500 mg/m2/dose intravenously every 8 hours or 800 mg orally 4 times a day) or high dose valacyclovir (2 grams three to four times daily or 2 grams three times daily) for the prophylaxis of CMV reactivation. Acyclovir or valacyclovir at lower doses for the prevention of HSV and VZV are allowed.
- Any condition which in the Investigator's opinion deems the participant an unsuitable candidate to receive study drug.
- Evidence for CMV infection defined as any positive CMV DNA qPCR test within 1 week prior to starting letermovir.
- Child Pugh class C liver disease.
