Eligibility Criteria
You may qualify if:
- The ECOG performance status ≤ 2.
- Life expectancy more than 3 months.
- Patients with relapsed and/or refractory to standard therapy or are intolerance to standard therapy diagnosed with 2022 World Health Organization (WHO) classification
- Peripheral T-cell lymphoma, not otherwise specified
- Nodal TFH cell lymphoma, angioimmunoblastic-type
- Nodal TFH cell lymphoma, follicular-type
- Nodal TFH cell lymphoma, NOS
- Patients currently requiring systemic therapy at the investigator's discretion.
- Patients with a lesion measuring 1.5 cm or more in its longest transverse diameter, as determined by CT, PET/CT or MRI scans according to the 2014 Lugano criteria.
You may not qualify if:
- The presence of overt leptomeningeal or active central nervous system (CNS) metastases, or CNS metastases that require local CNS-directed therapy or increasing doses of corticosteroids within the prior 2 weeks.
- Impaired cardiac function or clinically significant cardiac disease.
- Patients with interstitial pneumonia or history of drug-induced interstitial pneumonia/pneumonitis.
- For patients with lymphoma:
- Systemic antineoplastic therapy (including cytotoxic chemotherapy, alfa-interferon \[INF\], and toxin immunoconjugates) or any experimental therapy within 3 weeks or 5 half lives, whichever is shorter, before the first dose of study treatment.
- Therapy with tyrosine kinase inhibitor within 5 half-lives before the first dose of study treatment.
- Unconjugated monoclonal antibody therapies \< 6 weeks before the first dose of study treatment.
- Patients receiving systemic chronic steroid therapy or any immunosuppressive therapy (\>20 mg/day prednisone or equivalent).
