Tegavivint for Treating Patients With Relapsed or Refractory Large B-Cell Lymphoma

Официальное название

Phase Ib Trial of Tegavivint in Patients With Relapsed/Refractory C-MYC Overexpressing Large B-Cell Lymphoma

Обзор

This phase I trial tests the safety, side effects, and best dose of tegavivint in treating patients with large b-cell lymphomas that has come back (relapsed) or does not respond to treatment (refractory). Tegavivint may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving tegavivint may help control the disease.

Подробное описание

PRIMARY OBJECTIVES:

I. To determine the safety and tolerability of tegavivint in patients with relapsed/refractory c-Myc overexpressing large B-cell lymphoma.

II. To determine the maximum tolerated dose (MTD) or recommended phase II dose (RP2D) of tegavivint.

SECONDARY OBJECTIVES:

I. To determine the preliminary efficacy of tegavivint in patients with relapsed/refractory c-Myc overexpressing large B-cell lymphoma.

II. To determine the pharmacokinetic parameters of tegavivint.

EXPLORATORY OBJECTIVES:

I. To correlate response to tegavivint with the presence of MYC, FBW7 and SKP2 mutations.

II. To correlate response to tegavivint with TBL1 and c-Myc expression assessed by standard IHC on archived tumor biopsy.

III. To determine the effects of tegavivint on immune cell subsets viability and function.

OUTLINE: This is a dose-escalation study of tegavivint.

Patients receive tegavivint intravenously (IV) on study. Patients also undergo computed tomography (CT) and/or positron emission tomography (PET) and undergo blood sample collection throughout the trial.

Критерии участия

Критерии включения

One of the following three conditions:

• Relapsed/refractory histologically confirmed germinal center B-cell-like (GCB) and non-GCB diffuse large B cell lymphoma (DLBCL) with the following features:

• Increased expression of MYC (>= 40%) and BCL2 (>= 50%) by immunohistochemistry (IHC) or
• Presence of isolated MYC translocation Or
• Relapsed/refractory histologically confirmed high-grade B-cell lymphoma (HGBCL) (double hit \[DH\] and triple hit \[TH\]) with translocations of MYC and BCL2 and/or BCL6 Or
• Histologic transformation of indolent non-Hodgkin's lymphoma (NHL) to DLBCL

• Presence of BCL2 translocation with increased expression of MYC (≥40%) with or without MYC translocation
• Patients must have had at least two prior systemic therapies
• Patients must be ineligible for or refused autologous or allogenic hematopoietic stem cell transplantation or chimeric antigen receptor (CAR) T-cell therapy. Prior autologous stem cell transplant and/or CAR-T are allowed, if received >= 3 months prior to enrollment
• Age >= 18 years
• Eastern Cooperative Oncology Group (ECOG) performance status of 0-2
• Patients must have radiographically measurable disease by standard positron emission tomography (PET) uptake with at least one site of measured disease by standardized uptake value (SUV)
• Absolute neutrophil count (ANC) ≥ 500/mcL
• Platelet count ≥ 25,000/mcL
• Total bilirubin =< 1.5 x the upper limit of the normal range (ULN)
• Aspartate aminotransferase (AST)/alanine aminotransferase (ALT) < 3 x institutional ULN
• Creatinine clearance >= 60 ml/min by Cockcroft-Gault (actual body weight will be used to estimate creatinine clearance)
• Patients must be willing and able to understand and give written informed consent and comply with all study related procedures
• Women of child-bearing potential (WOCBP) and men who are sexually active with WOCBP must agree to use one hormonal contraceptive (e.g. combined oral contraceptives, patch, vaginal ring, injectables, and implants); intrauterine device (IUD) or intrauterine system (IUS); vasectomy or tubal ligation; and one effective method of contraception, including male condom, female condom, cervical cap, diaphragm or contraceptive sponge or abstain from sex for the duration of study participation and for 4 months following completion of tegavivint administration. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately.

Contraception includes:

• Total abstinence (when this is in line with the preferred and usual lifestyle of the patient. Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception
• Female sterilization (have had surgical bilateral oophorectomy with or without hysterectomy), total hysterectomy or tubal ligation at least 6 weeks before taking study treatment.

• Male sterilization (at least 6 months prior to screening). For female patients on the study the vasectomized male partner should be the sole partner for that patient
• Use of oral (estrogen and progesterone), injected or implanted combined hormonal methods of contraception or placement of an intrauterine device (IUD) or intrauterine system (IUS) or other forms of hormonal contraception that have comparable efficacy (failure rate <1%), for example hormone vaginal ring or transdermal hormone contraception
• Sexually active males must use a condom during intercourse while taking drug and for 4 months after stopping study treatment and should not father a child in this period. A condom is required to be used also by vasectomized men in order to prevent delivery of the drug via seminal fluid In case of use of oral contraception women should have been stable on the same pill for a minimum of 3 months before taking study treatment. Women are considered post-menopausal and not of child bearing potential if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g. age appropriate, history of vasomotor symptoms) or have had surgical bilateral oophorectomy (with or without hysterectomy) or tubal ligation at least 6 weeks ago. In the case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment is she considered not of child bearing potential
