Summary
A Phase 2 study to evaluate the efficacy of nanatinostat in combination with valganciclovir
in patients with relapsed/refractory EBV-positive lymphomas
Objectives
Patients with EBV-associated lymphomas have inferior outcomes with standard-of-care therapies
compared to those with EBV-negative disease. Nanatinostat is a selective class I HDAC
inhibitor which induces EBV lytic phase protein generation, activating (val)ganciclovir to
its cytotoxic form. This open-label, multicenter, multinational, single-arm, Phase 2 basket
study employs a Simon's 2-stage design to allow termination of enrollment into cohorts where
treatment appears futile, and will include the following cohorts of patients with EBV+
relapsed/refractory lymphomas:
1. EBV+ diffuse large B-cell lymphoma (DLBCL, NOS)
2. Peripheral T-cell lymphoma (PTCL), including PTCL-NOS and AITL
3. Post-transplant lymphoproliferative disorder (PTLD)
4. EBV+ lymphoproliferative disorders other than the above, including Extranodal NK/T-cell
lymphoma (ENKTL)
Eligibility
- EBV+ DLBCL, NOS and PTCL, NOS, and AITL: Relapsed/refractory disease following 1 or more prior systemic therapy(ies) with curative intent.
- For EBV+ PTLD patients: Relapsed/refractory disease following 1 prior therapy and must have received at least 1 course of an anti-CD20 immunotherapy. For patients with EBV+ PTLD only, age 12 years and older and weighing greater than 40 kg (Adolescent, Adult, Older Adult) are allowed
- For other EBV+ relapsed/refractory lymphoma: Following at least 1 course of an anit-CD20 immunotherapy and at least 1 course of anthracycline-based chemotherapy (unless contraindicated)
- No available therapies in the opinion of the Investigator
- Not eligible for high-dose chemotherapy with allogeneic/autologous stem cell transplantation or CAR-T therapy
- Measurable disease per Cheson 2007
- ECOG performance status 0, 1, 2
- Adequate bone marrow function

**Clinical trials are research studies that involve people. These studies test new ways to prevent, detect, diagnose, or treat diseases. People who take part in cancer clinical trials have an opportunity to contribute to scientists’ knowledge about cancer and to help in the development of improved cancer treatments. They also receive state-of-the-art care from cancer experts...
