Brief Summary
This is a Phase 1, first-in-human (FIH), open-label, multicenter, study of LB1901 administered to adult subjects with histologically confirmed CD4+ relapsed or refractory Peripheral T-cell lymphoma (PTCL) (PTCL not otherwise specified \[PTCL-NOS\] and angioimmunoblastic \[AITL\]), or relapsed or refractory cutaneous T-cell lymphoma (CTCL) (Sézary syndrome \[SS\] and mycosis fungoides \[MF\]).

Outcome Measures
Primary Outcomes (2)
To characterize the safety and tolerability of LB1901 and determine the optimal dose or recommended dose for expansion (RDE).
Multiple doses will be tested to establish a recommended dose.
Up to 2 years
To further characterize the safety and tolerability of LB1901 with the RDE identified in the dose escalation and determine the recommended Phase 2 dose (RP2D).
Treatment of additional patients at the recommended dose as identified in the initial dose escalation part of the study.
Up to 2 years
Secondary Outcomes (6)

Interventions
Eligibility Criteria
You may qualify if:
- Written informed consent.
- Subjects ≥ 18 years of age.
- Histologically confirmed diagnosis of CD4+ PTCL-NOS; OR CD4+ AITL; OR CD4+ CTCL(either MF or SS).
- Relapsed or refractory disease with at least two prior lines of systemic antineoplastic therapy.
- Subjects with confirmed CD30+ PTCL or MF must have previously received brentuximab vedotin.
- Subjects should have received at least two prior lines of standard of care therapies.
- For Subjects with PTCL-NOS or AITL, at least one measurable lesion according to the International Working Group (IWG) Response Criteria.
- For subjects with CTCL, disease stage IIB or higher based on TNMB system.
- Subjects must have an identified hematopoietic stem cell transplant (HSCT) donor available prior to enrollment. HLA typing may be performed for source identification.
- Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
- Adequate organ function.
- Women of childbearing potential must have a negative pregnancy test at screening.
- All Subject must agree to practice a highly effective method of contraception.
- Women and men must agree not to donate eggs (ova, oocytes) or sperm, respectively, until at least 1 year after receiving a LB1901.
You may not qualify if:
- Histologically confirmed CD8+ TCL - CD8 positivity in tumor must be confirmed within 3 months prior to apheresis by IHC or flow cytometry.
- Prior treatment with cellular immunotherapy (e.g., CAR-T) or gene therapy product directed at any target.
- Prior treatment with CD4-targeted therapy.
- History of allogeneic haematopoietic stem cells transplant.
- Antitumor therapy prior to apheresis as follows:
- Any systemic anticancer therapy (chemotherapy, targeted therapy including ADC, epigenetic therapy including HDAC inhibitor, retinoids, pralatrexate, proteasome inhibitor therapy, investigational drug) within 21 days or at least 5 half-lives, whichever is shorter.
- Anti-CCR4 monoclonal antibody or any other monoclonal antibody within 4 weeks or at least 5 half-lives, whichever is shorter.
- Cytotoxic therapy within 14 days.
- Immunomodulatory agent therapy within 7 days.
- Radiotherapy within 14 days.
- Immunosuppressant (e.g., cyclosporine or systemic steroids) above physiologic dosing within 7 days of apheresis.
- Therapeutic anticoagulants (such as warfarin, heparin, low molecular weight heparin) (at least 3 half-lives must have elapsed after the last dose at the time of apheresis).
- CNS disease prophylaxis (e.g., intrathecal methotrexate) at least 7 days before apheresis.
- History or active Hepatitis B or C infection (except hepatitis C cured with pharmacotherapy); or history of or current HIV infection.
- History of autoimmune disease requiring systemic immunosuppression/systemic disease modifying agents within the last 2 years.
