2. Age ≥18 years at time of provision of informed consent.
3. Histologically confirmed CD30-positive (via centrally assessed Ber-H2 targeted IHC; cut-offs listed in protocol) PTCL (allowed subtypes listed in protocol) or TMF per the revised WHO 2016 classification (Swerdlow, 2016) by central assessment (Note: Subjects must wait for central results before first dose of study drug).
The required cut-offs for the CD30-positivity are:
• Cohort A (PTCL): ≥10% by IHC • Cohort B (PTCL): ≥1 to <10% by IHC
• Cohort C (TMF): ≥1% by IHC
Measurable disease will be defined as below for each cohort:
• Cohorts A and B (PTCL cohorts): measurable by the modified Lugano Classification (Cheson, 2014); measurable disease of ≥1.5 cm diameter by computed tomography (CT), assessed locally for eligibility.
• Cohort C (TMF cohort): measurable by the Olsen Criteria (Olsen, 2011) including at least 1 cutaneous lymphoma lesion ≥2 cm in diameter, assessed locally for eligibility. Note: After the planned Interim Analyses, Cohorts A and B may be combined with the CD30-positivity defined as ≥ 1% by centrally assessed IHC.
4. Subjects must have relapsed or refractory disease AND the following:
• Cohorts A and B (PTCL cohorts): Subjects must have received at least 1 prior line of systemic therapy. For subjects with systemic ALCL, subjects must have failed or be intolerant to brentuximab vedotin [BV]; Adcetris®.
• Cohort C (TMF cohort): Subjects must have received at least 1 prior line of systemic therapy, and have exhausted systemic therapies with full approval for their treatment of transformed mycosis fungoides.
Note: intolerance is defined as a discontinuation of a drug due to a ≥ Grade 2 treatment-related adverse event that is clearly documented.
5. Completion of treatment with any radiotherapy, chemotherapy, antibody, immunoconjugates and/or another investigational drug ≥4 weeks (or 5 half-lives of the drug, whichever is shorter) prior to first dose of study drug.
Note: Subjects may be enrolled after a minimum of 2 weeks post radiation if radiation was for palliative intent to a single cutaneous lesion or single nodal region after discussion with the Sponsor.
6. Completion of an autologous hematopoietic stem cell transplantation at least 3 months prior to first dose of study drug (if applicable).
7. Resolution of any clinically significant previous therapy-related toxicity to ≤Grade 1 or to baseline if pre-existing condition (exception: Subjects with all grade alopecia and ≤Grade 2 peripheral neuropathy).
8. Eastern Cooperative Oncology Group (ECOG) performance score of 0 or 1.
9. Life expectancy ≥12 weeks.
10. Adequate laboratory functional values. (Note: transfusions and growth factors allowed during Screening; however, transfusion dependency defined as requiring blood products > once per week not allowed):
a) Platelet count ≥50,000/mm3;
b) Hemoglobin ≥8.0 g/dL (≥4.96mmol/L);
c) Absolute neutrophil count >1,000/mm3;
d) Alanine transaminase/aspartate transaminase ≤ 3x the upper limit of normal (ULN) or ≤ 5x for subjects with documented hepatic involvement with lymphoma;
e) Total bilirubin ≤1.5 x ULN or <3 x ULN for subjects with Gilbert's disease or documented hepatic involvement with lymphoma;
f) Serum creatinine ≤1.5mg/dL or measured or calculated (per institutional standard) creatinine clearance ≥30mL/min for subjects with creatinine levels >1.5 x ULN;
11. If female of child-bearing potential, must not be pregnant or be breastfeeding and required to have a negative urine or serum pregnancy
test within 3 days prior to the first dose of study drug. Note: Urine pregnancy tests that cannot be confirmed as negative, require a confirmatory negative serum pregnancy test. In addition, females of childbearing potential must agree use of a highly effective method of contraception for the course of the study from 14 days prior to the first dose of study drug until 60 days after the last dose of study drug.
Non-childbearing potential is defined as:
• Postmenopausal: defined as no menses for 12 months without an alternative medical cause. A high follicle-stimulating hormone (FSH) level in the postmenopausal range may be used to confirm postmenopausal state in women not using hormonal contraception or hormonal replacement therapy. In the absence of 12 months of amenorrhea, FSH measurements indicating post-menopausal status must be documented in subject's medical history.
• Permanently sterile: documented permanent sterilization eg, hysterectomy, bilateral salpingectomy and bilateral oophorectomy.
12. If male, surgically sterile or agrees to use a highly effective method of contraception, prior to the first dose of study drug until 60 days after the last dose of study drug. |

d) active Hepatitis B or Hepatitis C as defined in the protocol. Antiviral prophylaxis for chronic Hepatitis B virus infection may be used at the discretion of the investigator. Note: Subjects must meet criteria defined in the protocol to be allowed to be enrolled in the study).
