What You Need to Know Before You Apply

What is the purpose of this trial?

The hypotheses of this study are that single agent CPI-0209 will be safe and well tolerated in patients with advanced (stage IB-IVB) mycosis fungoides (MF)/Sézary syndrome (SS) who have had at least one prior systemic therapy, and that in these patients, CPI-0209 will demonstrate efficacy and be worth of further study.

Will I have to stop taking my current medications?

The trial requires a washout period (time without taking certain medications) for some treatments before starting the study drug. You may need to stop certain medications, especially if they are systemic therapies for mycosis fungoides/Sézary syndrome or strong CYP3A inducers or inhibitors. It's best to discuss your specific medications with the trial team.

What Are the Treatments Tested in This Trial?

Interventions

• Tulmimetostat

Trial Overview The trial tests Tulmimetostat (CPI-0209) on patients with specific skin lymphomas to see if it's safe and effective after other treatments failed. It's given as a single agent, meaning no other drugs are combined in the treatment regimen.

How Is the Trial Designed?

Group I: Dose Expansion Cohort: Tulmimetostat (CPI-0209) - 300 mg Experimental Treatment 1 Intervention

Daily CPI-0209 by mouth for days 1-28 of each 28-day cycle. Dose will be the maximum-tolerated dose found during the dose de-escalation cohort which was 300 mg.

Group II: Dose Expansion Cohort: Tulmimetostat (CPI-0209) - 200 mg Experimental Treatment 1 Intervention

Daily CPI-0209 by mouth for days 1-28 of each 28-day cycle. Dose will be 200 mg as the maximum tolerated dose of 300 mg found during the initial dose expansion cohort caused numerous dose reductions.

Group III: Dose De-Escalation Cohort: Tulmimetostat (CPI-0209) Experimental Treatment 1 Intervention

Daily CPI-0209 by mouth for days 1-28 of each 28-day cycle. Dose will depend on dose level assignment of 300 mg daily, 250 mg daily, or 200 mg daily.
