Safety and Efficacy of OT-82 in Participants With Relapsed or Refractory Lymphoma

Status unconfirmed · Phase 1

Conditions studied: Lymphoma, Lymphoma, Non-Hodgkin, Lymphoma, B-Cell, Lymphoma, T-Cell, Lymphoma, Follicular, Lymphoma, Peripheral T-Cell, Lymphoma, Hodgkin

In brief

This research study will test OT-82, which is an investigational ("research" or "experimental" ) drug. The study has two stages (Stage 1 and Stage 2). The purpose of Stage 1 is to determine the safety and tolerability and the maximum tolerated dose (MTD) or the maximum tested dose of OT-82 administered orally to participants. The purpose of Stage 2 is to determine the preliminary efficacy of OT-82 in relapsed or refractory lymphoma at the MTD or the maximum tested dose. Both parts of the study will also evaluate the pharmacokinetics (absorption, distribution, metabolism, elimination) of OT-82. OT-82 treatment slowed the growth, reduced the size, or in some cases cured certain cancers in animal studies. It is hoped that participants with relapsed or refractory lymphoma treated with OT - 82 in this study will experience slowing tumor growth and/or reduction of tumor size.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Age ≥ 18 years.
• Provides signed informed consent before initiation of any study-specific procedures or treatment.
• Histologically (tumor tissue) confirmed diagnosis of lymphoma that has progressed despite prior treatment, and for which additional options leading to meaningful clinical benefit are not available. Lymphoma diagnoses may include the following:
• a. Confirmed histological diagnosis of the following types of B-cell Non-Hodgkin lymphoma (NHL): i. Low-grade B-cell NHLs including, but not limited to, FL, MCL, MZL, PMBL, LPC, or CLL/SLL. ii. Intermediate to high grade B-cell NHLs including, but not limited to DLBCL and other intermediate grade B-cell NHL, with disease progression following stem cell transplant or patient must be unwilling, unable or not an appropriate candidate for such. iii. Transformed Follicular Lymphoma. b. PTCL and others T-cell lymphoma, in which there is measurable non-cutaneous disease.
• c. Hodgkin's Lymphoma
• Measurable disease in all lymphoma classes except PTCL.
• Defined as nodal lesions >1.5 cm or extra-nodal, non-cutaneous lesions > 1.0 cm.
• Target lesions that have been previously irradiated and have not progressed since radiation are not considered measurable.
• Patients with PTCL may be eligible if they do not have measurable disease if they have skin disease.
• ECOG performance status of 0 or 1. This is a measure of a participant's ability to manage self care, mobility, work status, and other measures.
• Adequate baseline organ function.
• Adequate baseline hematologic (blood) function.
• Negative blood pregnancy test result obtained during screening if the patient is sexually mature woman who has not undergone a hysterectomy or ovary removal or has not been naturally postmenopausal for at least 24 consecutive months.
• Participant agrees to use acceptable contraceptive methods for the duration of time on the study, and continue to use acceptable contraceptive methods for 3 months after the last treatment with OT-82:
• Participant agrees to, and be capable of, adhering to the study visit schedule and other protocol requirements, including follow-up for survival.

You may not qualify if…

• Persistent clinically significant toxicities from previous anticancer therapy (excluding alopecia, which is permitted, and excluding Grades 2 and 3 laboratory abnormalities if they are not associated with symptoms, are not considered clinically significant by the Investigator, and can be managed with available medical therapies).
• Treatment with cytotoxic, biologic, or targeted therapies for lymphoma within 14 days before administration of the patient's first dose of OT-82.
• Treatment with an investigational drug within 28 days before administration of the patient's first dose of OT-82.
• Treatment with a stem cell transplant with an infusion of stem cells no less than 8 weeks before administration of the patient's first dose of OT-82. There should be no graft versus host disease > Grade 1 and participant should have discontinued all immunosuppressive therapy for such ≥ 2 weeks from OT-82 treatment.
• Radiation therapy within 14 days before administration of the patient's first dose of OT-82.
• Major surgical procedure within 28 days before administration of the patient's first dose of OT-82.
• Physical abnormality or medical condition that limits swallowing oral solutions, and/or has a history of non-adherence to oral therapies.
• Clinically significant gastrointestinal disorder that may alter absorption such as malabsorption syndrome or major resection of the stomach or bowels
• Additional active malignancy that may confound the assessment of the study endpoints. If the participant has a past cancer history (i.e. active malignancy within 2 years before study entry) with substantial potential for recurrence, this must be discussed with the Sponsor before study enrollment. Patients with the following concomitant neoplastic diagnoses are eligible: nonmelanoma skin cancer and carcinoma in situ (including transitional cell carcinoma, cervical cancer, anal carcinoma, and melanoma in situ).
• Breastfeeding.
• Clinically significant cardiovascular disease including, but not limited to:
• Uncontrolled or any New York Heart Association Class III or IV congestive heart failure.
• Uncontrolled angina, history of myocardial infarction, unstable angina, or stroke within 6 months before study entry.
• Systolic blood pressure > 170 mm Hg or diastolic blood pressure > 110 mm Hg, or clinically significant arrhythmias not controlled by medication.
• Average QTc interval by QTcF on triplicate ECGs at screening or baseline > 470 msec (females) or > 450 msec (male).
• History of additional risk factors for a cardiac condition known as torsade de pointes (e.g., heart failure, low potassium, family history of long QT syndrome, use of concomitant medications that prolong the cardiac QT/QTc interval).
• Uncontrolled, clinically significant pulmonary disease (e.g., chronic obstructive pulmonary disease, pulmonary hypertension) that, in the opinion of the Investigator, would put the patient at significant risk for pulmonary complications during the study (patient must not be dependent on oxygen).
• History of brain or leptomeningeal malignant disease (CNS imaging is not required before study entry unless there is a clinical suspicion of CNS involvement).
• Primary CNS lymphoma.
• Condition requiring systemic treatment with either corticosteroids (> 10 mg daily prednisone equivalents) or other immunosuppressive medications within 14 days before administration of the patient's first dose of OT-82. Inhaled or topical steroids and adrenal replacement doses ≤ 10 mg daily prednisone equivalents are permitted in the absence of active autoimmune disease.
• Uncontrolled illness including, but not limited to, uncontrolled infection, disseminated intravascular coagulation, or psychiatric illness/social situations that would limit compliance with study requirements.
• Known positive status for HIV and:
• Not receiving optimal anti-HIV therapy
• Demonstrated to be noncompliant with anti-HIV therapy.
• Has evidence of worsening HIV viral load (as assessed by HIV real-time qPCR).
