Phase 3 Study of QTX-2101 for Acute Promyelocytic Leukemia

This Phase 3 study is testing a new oral capsule, QTX-2101, combined with ATRA (all-trans retinoic acid), for adults with newly diagnosed low-risk acute promyelocytic leukemia (APL). APL is a type of fast-growing blood cancer. Researchers want to see if QTX-2101 + ATRA is as effective and safe as the standard treatment, which is IV arsenic trioxide (ATO) + ATRA. The study will look at how much QTX-2101 is in the blood and if participants achieve molecular complete remission (meaning no signs of cancer cells). You may be able to join if you are 18 to 70 years old and have a confirmed diagnosis of low- or intermediate-risk APL. The current status of this study is unclear.

Study design
This is an open-label Phase 3 study, meaning both you and your doctors will know which treatment you are receiving. It plans to enroll 150 participants.
What's involved
During the induction phase, you would receive QTX-2101 + ATRA or IV ATO + ATRA daily for up to 60 days. During the consolidation phase, QTX-2101 or IV ATO is given daily according to your doctor's plan.
Compensation
Not stated in the trial record.
Follow-up
The study will measure molecular complete remission for up to 60 days of induction and three 8-week cycles of consolidation treatment.

  • Maximum observed plasma (concentration (Cmax) of QTX-2101 for ASIIIUp to 1 cycle of consolidation therapy (each cycle is 8 weeks)

    Cmax is defined as the maximum observed plasma concentration following administration of \[investigational product\], determined from plasma concentration-time data.

  • Molecular complete remission (molecular CR) rateUp to 60 days of induction and 3 8-week cycles of consolidation treatment

    mCR is defined as the absence of detectable PML-RARA fusion transcript in bone marrow assessed by a validated quantitative reverse transcription polymerase chain reaction (RT-qPCR) assay .The mCR rate is defined as the proportion of participants achieving molecular remission at the specified assessment time point following induction and consolidation therapy.
