Clinical Trial Summary

Brentuximab vedotin is an antibody-drug conjugate targeting CD30, one of surface antigens expressed in lymphoma cells. Fanale MA, et al. reported the results of a phase I study with weekly dosing of brentuximab vedotin in patients with relapsed/refractory CD30-positive hematologic malignancies (Clin Cancer Res. 2012) showed tumor regression in 85% of patients. Thus, the overall objective response rate was 59% (24/44) including 34% (n = 14) of complete remissions. This study mainly included Hodgkin lymphoma (n = 38) and anaplastic large cell lymphoma (n = 5). However, its efficacy in other types of NHL has never been reported although this study enrolled one patient with peripheral T-cell lymphoma not otherwise specified (PTCL-NOS).

CD30 (TNFRSF8) is a transmembrane glycoprotein of the tumor necrosis factor receptor (TNFR) superfamily, and it is involved in signal transduction via the activation of the NF-κB pathway and the mitogen-activated protein kinases (MAPKs), ultimately modulating cell growth, proliferation and apoptosis. CD30 is a non-lineage-specific activation marker expressed by scattered B and T immunoblasts. In addition, a subset of cases in virtually all T-cell lymphoma entities may also express CD30 but at variable and generally lower levels. In fact, a recent study in 22 patients with extranodal NK/T-cell lymphoma showed 75% of positive rate of CD30 expression (75%). Moreover, CD30 expression was also documented in the tumor sample of EB virus positive diffuse large B-cell lymphomas (EBV + DLBCL) of the elderly (28.9%, 11/38). Therefore, Brentuximab vedotin may have potential benefits for patients with CD30-positive NHL other than anaplastic large cell lymphoma such as CD30-positive PTCLs, NOS. Considering the role of CD30 in signal transduction pathway associated with tumor growth and proliferation, its expression may be associated with tumor aggressiveness. In accordance with this, it is more likely that relapse or refractory NHLs may have CD30 expression, and the potential benefits of this promising agent as a salvage therapy deserve to be further investigated in these patients who have high risk of treatment failure. Thus, we designed a phase II study for relapsed or refractory NHL patients. This study is to explore the safety and activity of dosing once every 3 weeks of Brentuximab vedotin in patients with relapsed or refractory CD30-positive NHL other than anaplastic large cell lymphoma.

Description:

The principal investigator use a Simon two-stage minimax design based on overall response rates. Overall disease control rates will be calculated as the percent of patients that have confirmed complete response (CR) or partial response (PR) or stable disease (SD) by radiographic response including CT and/or PET scans. We assume a P0 as 20%, and designate a target rate (P1) as 40%. Under the error probabilities (α=0.05, β=0.20), eighteen patients will be enrolled in the first stage. If overall disease control rate is ≤ 4/18 in the first stage, this study will be stopped. If not, this study will recruit patients up to 33 considering 20% of drop out rate.

Intent-to-treat analysis will be applied to all primary and secondary efficacy endpoints. Response rate will be analyzed based on the response criteria according to Cheson 2007 (Cheson BD, et al. J Clin Oncol 2007; 25 (5):579-586), and data related to overall response rate will be analyzed by statistical analysis including Chi test to evaluate predictive factors for response to study drug.

Overall rate of disease control : CR, PR and SD Progression-free survival : Time between the date of treatment start and the date of death due to any cause or date of disease progression (Up to 36months) Data related to survival rate for all patients will be analyzed based on log-rank test by the Kaplan-Meier method.

5. Life expectancy of greater than 3 months

6. ECOG performance status = 2

7. Male or female patients 18 - 75 years

8. Female patient is either post-menopausal for at least 1 year before the screening visit or surgically sterile or if of childbearing potential, agree to practice 2 effective methods of contraception, at the same time, from the time of signing the informed consent through 6 months after the last dose of study drug, or agrees to completely abstain from heterosexual intercourse.

9. Male patients, even if surgically sterilized, (i.e., status post vasectomy) agree to practice effective barrier contraception during the entire study period and through 6 months after the last dose of study drug, or agrees to completely abstain from heterosexual intercourse.

10. Voluntary written informed consent must be given before performance of any study-related procedure not part of standard medical care, with the understanding that consent may be withdrawn by the patient at any time without prejudice to future medical care.

11. Clinical laboratory values as specified below within 7 days before the first dose of study drug:

12. Serum creatinine must be < 2.0 mg/dL and/or creatinine clearance or calculated creatinine clearance > 40 mL/minute.

13. Hemoglobin must be = 8g/dL.

15. Platelets (Plts) = 75,000/; G-CSF can be given prior to start of brentuximab vedotin and during brentuximab vedotin treatment to achieve target ANC; platelet transfusion can also be given prior to the start of brentuximab vedotin and during brentuximab vedotin treatment to achieve a target platelet = 75,000/uL
