Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

Histologically confirmed diffuse large B-cell lymphoma that is refractory to prior therapy or relapsed after prior therapy.

FDG PET-CT (disease) positive baseline scan with measurable disease.

The patient must have received prior therapy that included:

  • CD20-targeted therapy (for example, rituximab),
  • Alkylating agent (for example, cyclophosphomide), and
  • Steroid, unless the patient is steroid intolerant

Exposure to at least 1 or 2 (but no more than 3) prior systemic cytotoxic chemotherapeutic regimens.

Note: Only those subjects who are not eligible for high-dose chemotherapy and autologous stem cell transplant (HD-ASCT), or who refuse HD-ASCT, are eligible with exposure to only 1 prior cytotoxic chemotherapeutic regimen.

ECOG performance status of 0-1.

The patient must be a stable baseline with CTCAE grade ≤ 2 regarding any acute or chronic toxicity associated with prior therapy, and have discontinued prior anti-cancer therapy for ≥ 14 days prior to C1D1; mitomycin-C for at least 6 weeks prior to C1D1; SCT ≥ 2 months prior to C1D1.

Note: Palliative steroids for control of disease-related symptoms are allowed and maintenance hormone therapy is allowed.

Adequate organ function including:

  • Hematologic: ANC ≥ 0.5 x 10^9/L. and platelets ≥ 50 x 10^9/L.
  • Hepatic: Total Bilirubin ≤ 2 x ULN (patients with Gilbert's syndrome must have total bilirubin ≤ 3 x ULN) and serum transaminase levels ≤ 2.5 x ULN. In the case of known liver metastasis (i.e., radiological or biopsy documented), serum transaminase levels must be ≤ 5 x ULN.
  • Renal: Serum creatinine ≤ 2 x ULN, or creatinine clearance ≥ 60 mL/min/1.73 m2 for subjects with serum creatinine levels above 2 x ULN.

Willingness to: 1.) undergo pre-treatment biopsy to obtain adequate tissue for analysis (e.g., core needle, excisional or incisional tumor biopsy) or 2.) provide archived tumor (e.g., FFPE block) for analysis.

Exclusion Criteria:

Eligibility for high-dose chemotherapy (HDT) and stem cell transplant (SCT). Note: Subjects who progressed ≥ 2 months after HDT/SCT are eligible

Concurrent malignancies requiring treatment.

Primary mediastinal (thymic) large B-cell lymphoma

Symptomatic CNS or leptomeningeal involvement of lymphoma.

Concurrent clinically significant illness, medical condition, surgical history, physical finding, electrocardiogram or laboratory finding that, in the opinion of the investigator, could adversely affect the safety of the patient or impair the assessment of the study results.

Signs or symptoms of heart failure characterized as greater than NYHA Class II or other significant cardiac abnormalities.

Pregnant or breast-feeding.

Prior exposure to PNT2258.

Life expectancy less than 3 months.

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: PNT2258
PNT2258 will be administered at 120 mg/m2 on days 1-5 of a 21-day cycle. Treatment may continue unless there is disease progression or the occurrence of unacceptable toxicity for a total of 8 "induction" cycles of therapy. Subjects with CR/CMR, PR/PMR or SD/NMR at the end-of-cycle 8 scan then receive ongoing PNT2258 therapy at a dose of 100 mg/m2 on days 1-4 of a 28 day cycle until progressive disease, the occurrence of unacceptable toxicity, non-compliance, voluntary withdrawal or if in the opinion of the investigator the subject is no longer benefiting from exposure to PNT2258.
Drug: PNT2258
Other Names:
  • DNAi, BCL2 targeted therapy

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

19 months

Secondary Outcome Measures

Secondary Outcome Measures
