Interventions: Drug: Onalespib

Registration Number: NCT02572453

Lead Sponsor: National Cancer Institute (NCI)

Brief Summary: This phase II trial studies how well onalespib works in treating patients with anaplastic large cell lymphoma, mantle cell lymphoma, or diffuse large B-cell lymphoma that has not responded to previous treatment (refractory) or that has returned after a period of improvement (recurrent). Onalespib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.

Detailed Description: PRIMARY OBJECTIVE:

I. Overall response rate (ORR) to single agent AT13387 (onalespib) as measured by the proportion of partial and complete responses (PR + CR) in patients with relapsed/refractory ALK positive (+) anaplastic large cell lymphoma (ALCL), mantle cell lymphoma (MCL), and BCL6+ diffuse large B cell lymphoma (DLBCL).

SECONDARY OBJECTIVES:

I. Progression free survival (PFS) and overall survival (OS), as well as duration of response (DOR) of single agent AT13387 (onalespib) in patients with ALK+ ALCL, MCL, and BCL6+ DLBCL.

II. Safety and tolerability of single agent AT13387 (onalespib) in patients with ALK+ ALCL, MCL, and BCL6+ DLBCL.

EXPLORATORY OBJECTIVES:

I. Measurement of on-target activity of AT13387 (onalespib) in ALK+ ALCL, MCL, and BCL6+ DLBCL through immunoblotting and immunohistochemistry of pre-treatment, on-treatment, and time of progression tumor biopsies for HSP90 clients.

II. Determination of genetic and transcriptional markers for response and resistance to AT13387 (onalespib) in patients with ALK+ ALCL, MCL, and BCL6+ DLBCL.

OUTLINE:

Patients receive onalespib intravenously (IV) over 1 hour on days 1, 2, 8, 9, 15, and 16. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 6 months for up to 1 year.

Recruitment & Eligibility

Status: TERMINATED

Sex: All

Target Recruitment: 25

Inclusion Criteria

Patients must have histologically confirmed, relapsed/refractory ALK+ ALCL (with ALK positivity defined by immunohistochemistry and/or fluorescence in situ hybridization [FISH]/cytogenetics from any prior biopsy), MCL, or BCL6+ DLBCL (with BCL6 positivity defined by immunohistochemistry from any prior biopsy) and meet the following criteria:
Patients must have measurable disease that has not been previously irradiated, defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded for non-nodal lesions and short axis for nodal lesions) as >= 20 mm (>= 2 cm) with conventional imaging or >= 10 mm with spiral computed tomography (CT) scan; if the patient has been previously irradiated, there must be evidence of progression since the radiation
- Please note, this trial includes mandatory tumor biopsies pre-treatment, during cycle 1 and at the time of disease progression of accessible tumor; having accessible tumor for biopsy is not required for eligibility; we expect that at least 80% of patients will have accessible tumor for these biopsies, however
Prior therapy
- Please note, the washout period for prior therapies cannot be shortened
- Please note, prior therapies can be from any time in the past
ALK+ ALCL: patients must have disease that has relapsed and or is refractory to prior therapy, which must have included a multiagent chemotherapy regimen including an anthracycline, if not contraindicated, and prior brentuximab; prior crizotinib or other ALK inhibitor therapy, while recommended, is not mandatory; patients must have relapsed following or be ineligible for, or refuse, autologous stem cell transplant
MCL: patients must have disease that has relapsed and or is refractory to prior therapy, which must have included a multiagent chemotherapy regimen and prior ibrutinib or other BTK inhibitor therapy; patients must have relapsed following or be ineligible for, or refuse, autologous stem cell transplant
BCL6+ DLBCL: patients must have disease that has relapsed and or is refractory to prior therapy, which must have included an anthracycline, if not contraindicated; patients must have relapsed following or be ineligible for, or refuse, autologous stem cell transplant
Eastern Cooperative Oncology Group (ECOG) performance status =< 2 (Karnofsky >= 60%)
Life expectancy of greater than 3 months
Absolute neutrophil count >= 1,000/mcL
Platelets >= 75,000/mcL, unless due to marrow involvement by lymphoma in which case a platelet count of >= 30,000/mcL will be used
Total bilirubin =< 1.5 x upper limit of normal (ULN), unless due to Gilbert's syndrome or hemolysis, in which case =< 3.0 x ULN is allowed
Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =< 3.0 x institutional upper limit of normal
Creatinine =< 1.5 x ULN or a creatinine clearance >= 50 mL/min/1.73 m^2 for patients with creatinine levels above institutional normal
Potassium above the institutional lower limit of normal (supplementation to meet this is allowed)
Magnesium above the institutional lower limit of normal (supplementation to meet this is allowed)
Human immunodeficiency virus (HIV)+ patients are eligible for the trial provided they meet the other study criteria in addition to the following:
- CD4+ T-cells >= 250/mm^3
- HIV sensitive to antiretroviral therapy
- Zidovudine not allowed
- Long term survival anticipated on the basis of HIV alone were it not for the lymphoma
- No concurrent acquired immunodeficiency syndrome (AIDS)-defining illness other than the lymphoma
The effects of AT13387 (onalespib) on the developing human fetus are unknown; for this reason, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation, and for 4 months after the completion of AT13387 (onalespib) 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; men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study participation, and 4 months after completion of AT13387 (onalespib) administration
Although the pharmacokinetic (PK) data in humans is still unknown, the potential for drug-interaction cannot be ruled out; pre-clinical studies suggest that AT13387 (onalespib) is a substrate of P-glycoprotein (P-gp), a moderate inhibitor of BCRP and P-gp, and a strong inhibitor of MATE 1/2-K; patients must be willing to not take St. John wort or grapefruit juice while participating in this trial and should avoid drugs that are strong inducers of P-gp, and to switch to alternative drugs when available
Hepatitis B positive patients are eligible; prophylactic hepatitis B virus (HBV) therapy is recommended but only if there is no circulating virus detectible
Transformed lymphoma patients are eligible
Ability to understand and the willingness to sign a written informed consent document

Exclusion Criteria

Patients who have had chemotherapy or radiotherapy within 4 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering the study or those who have not recovered from adverse events due to agents administered more than 4 weeks earlier; steroids for symptom palliation are allowed, but must be either discontinued or on stable doses at the time of initiation of protocol therapy
Patients who are receiving any other investigational agents; all investigational agents other than ibrutinib must have been discontinued at least 4 weeks prior to beginning treatment; prior ibrutinib therapy must have been discontinued at least 2 weeks prior to beginning therapy
Patients with known leptomeningeal or brain metastases should be excluded from this clinical trial because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events; imaging or spinal fluid analysis to exclude central nervous system (CNS) involvement is not required, unless there is clinical suspicion by the treating investigator
History of allergic reactions attributed to compounds of similar chemical or biologic composition to AT13387 (onalespib)
Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
- There will be no exclusion of patients with known visual impairment or symptoms, including by not limited to peripheral flashes (photopsia), blurred or double vision, floaters, color distortion and dimness, difficulties with light/dark accommodation, tunnel vision or other field defects, halos, apparent movement of stationary objects, and complex disturbances; patients will have a baseline ophthalmologic exam to serve as a point of comparison and further exams as needed should visual symptoms develop; no pretreatment eye exam findings or ocular symptoms have been associated with an increased risk of ocular toxicity seen with AT13387
Pregnant women are excluded from this study because AT13387 (onalespib) has the potential for teratogenic or abortifacient effects; because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with AT13387 (onalespib), breastfeeding should be discontinued if the mother is treated with AT13387 (onalespib)
Patients, who have had a major surgery or significant traumatic injury within 4 weeks of start of study drug, patients who have not recovered from the side effects of any major surgery (defined as requiring general anesthesia) or patients that may require major surgery during the course of the study

BCL6+ DLBCL	Onalespib	Patients receive 160-mg/m2 onalespib by IV over 1 hour on days 1, 2, 8, 9, 15, and 16 of each 28-day cycle. Patients will continue on treatment indefinitely as long as they are responding and tolerating treatment.
Relapsed MCL	Onalespib	Patients receive 160-mg/m2 onalespib by IV over 1 hour on days 1, 2, 8, 9, 15, and 16 of each 28-day cycle. Patients will continue on treatment indefinitely as long as they are responding and tolerating treatment.

Primary Outcome Measures

Name	Time	Method
Objective Response Rate	Assessed every 2 cycles during treatment until disease progression; patients who discontinue for reasons other than progression will be evaluated every 6 months for up to 1 year after ending treatment or until progression or next therapy	Objective response (OR) = Complete + Partial (CR + PR) Per International Harmonization Project for lymphoma criteria, CR is defined as the disappearance of all evidence of disease. For FDG-avid or PET positive sites of disease prior to therapy, a mass of any size is permitted if PET negative; for variably FDG avid or PET negative lesions, regression to normal size on CT is necessary. The spleen or liver must also be nonpalpable with disappearance of any nodules, and the bone marrow, if initially involved, must be cleared on repeat biopsy. PR is defined as regression of measurable disease and no new sites of disease: a \>50% decrease in the sum of the diameters of the up to 6 largest dominant masses with no increase in size of other masses. If the sites of disease were PET positive at baseline, there must be at least one previously involved site that remains PET positive.

Secondary Outcome Measures

Name	Time	Method
Frequency of Toxicities	Assessed days 1, 2, 8, 9, 15, 16 of each 28-day cycle during treatment until progression; patients who discontinue for reasons other than progression evaluated every 6 months for up to 1 year after ending treatment or until progression or next therapy	Will be graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events version 4.0 (version 5.0 is used staring April 1, 2018). Toxicities will be summarized with counts and proportions within each cohort and overall.
Progression-free Survival	From the date of study entry until documentation of first progression or death from any cause; progression assessed every 2 cycles during treatment until disease progression or death	The progression-free survival will be estimated by Kaplan-Meier method. Progressive disease is defined by the International Harmonization Project for lymphoma criteria: any new lesion or an increase by \> 50% of previously involved sites from nadir. This includes the appearance of any new lesion(s) \> 1.5cm in any axis, a \> 50% increase in the sum of diameters of \> 1 site of disease or \> 50% increase in the longest diameter of a previously identified node \>1cm in short axis. If the sites of disease were PET positive at baseline, they must remain PET positive.
Overall Survival	From the date of study entry until death from any cause; assessed every 6 months for up to 1 year after ending treatment	The overall survival will be estimated by Kaplan-Meier method. Median follow-up time will be assessed using the reverse Kaplan-Meier method.
Duration of Response	From first objective response (partial response or complete response) until the first date of documented progression assessed every 2 cycles or death due to any cause; assessed every 6 months up to 1 year after ending treatment	Duration of response will be evaluated only in patients who respond with either a partial response or complete response while on study.
