纳入标准
- ≥18 years of age.
- Able to understand and comply with protocol-required study procedures and voluntarily sign a written informed consent document.
- Sufficient key organ performance and coagulation.
- Female subjects of childbearing potential (postmenarcheal, has an intact uterus and at least one ovary, and is \<1 year postmenopausal) must agree to use a highly effective method of contraception from enrollment through at least 12 months after last dose of DR-01.
- Male subjects must agree to use acceptable effective method(s) of contraception.
- Must have discontinued at least one prior line of systemic therapy.
- Additional immunophenotypic and symptomatic criteria must be met.
- Subjects must have failed at least one prior systemic regimens.
- Availability of post-progression tissue sample or willingness to consent to a baseline biopsy.
- Histologically confirmed diagnosis of a cytotoxic lymphoma by a hematopathologist (according to the WHO 2016 classification \[Swerdlow 2016\]).
- For Part A only, evaluable disease is acceptable.
- For Part B2 only, evaluable by the following response criteria as documented during Screening:
- For cytotoxic PTCL-NOS, ENKTL, MEITL, EATL, SPTCL - Subjects must have radiographically measurable disease by computed tomography (CT) or CT/positron emission tomography (PET) scan defined as at least one node measuring \>1.5 cm or measurable extranodal lesion of at least 1.0 cm in longest diameter to be evaluated by Lugano criteria (Cheson 2014).
- For PCGDTCL, ET-CTCL, HVLPD, cytotoxic CuPTCL-NOS - Subjects with primary cutaneous variants must have at least 1 measurable lesion that is evaluable using the Olsen criteria (Olsen 2021) or have leukemic involvement that can be evaluated using modified TPLL response criteria (Staber 2019).
- For HSTCL, ANKL, SysEBV TCL - Subjects with hepatosplenic disease without measurable disease by Lugano criteria (Cheson 2014) or leukemic involvement in BM or peripheral blood that is evaluable for response using a modified TPLL response criteria (Staber 2019).
- Autologous HSCT within 40 days of C1D1, allogeneic HSCT within 90 days
- Any immunosuppressive therapy for GVHD for subjects who are post allogeneic HSCT.
- Major surgery within 28 days of C1D1 (requires more than local anesthesia or plexus blockade).
排除标准
- A reactive LGL lymphocytosis to a viral infection or LGL associated with myelodysplastic syndrome (MDS) or acute myeloid leukemia (AML).
- Active systemic infection or severe localized infection requiring systemic antibiotics, antivirals or antifungals.
- Active or suspected malignant central nervous system involvement.
- Life-threatening, severe complications of malignancy (e.g., uncontrolled bleeding, pneumonia with hypoxia or shock, and/or disseminated intravascular coagulation).
- Active known second malignancy.
- Infection with human immunodeficiency virus (HIV) type 1 or 2 (HIV-1 or HIV-2).
- Hepatitis B infection (hepatitis B virus surface antigen \[HBsAg\] positive), or hepatitis C (hepatitis C virus \[HCV\] antibody positive, confirmed by HCV ribonucleic acid). Subjects with HCV with undetectable virus after treatment are eligible.
- History of clinically significant cardiac disease or congestive heart failure greater than New York Heart Association (NYHA) Class II.
- Use of systemic corticosteroids at prohibited dose levels within 15 days prior to C1D1 (except for prophylaxis for radiodiagnostic contrast reactions and study-defined premedication) or use of other non-biological immunosuppressive drugs within 15 days or 5 half-lives (whichever is less) prior to C1D1.
- Any condition requiring hormonal therapy (except for contraception, hormone replacement therapy and hormonal prophylaxis for a prior malignancy).
- Any other medical or psychiatric condition, or laboratory abnormality that would increase the risk associated with study participation, in the opinion of the Investigator or Medical Monitor.
