Purpose

This study evaluates a fenretinide phospholipid suspension for the treatment of T-cell non-Hodgkin's lymphoma (NHL).

Detailed Description

      Fenretinide has been shown to be a relatively safe and effective anticancer therapy; however,
      dose limiting toxicities due to the excipients used in previous formulations has impeded its
      therapeutic utility. The product formulation in the current study (ST-001) is a phospholipid
      suspension of nanoparticle sized fenretinide. The current study is a Phase 1 trial in
      relapsed/refractory (R/R) T-cell non-Hodgkin's lymphoma in order to determine the safety
      profile, pharmacology, and maximum tolerated dose (MTD) of ST-001 nanoFenretinide. Targeted
      T-cell non-Hodgkin's lymphoma (T-Cell NHL) indications include: (1) Cutaneous T-cell lymphoma
      (CTCL) including mycosis fungoides (MF) and Sézary Syndrome (SS); (2) non-cutaneous T-cell
      lymphoma (non-CTCL) subtypes: angioimmunoblastic T-cell lymphoma (AITL), peripheral T-cell
      lymphoma (PTCL) not otherwise specified (NOS); and, follicular T-cell lymphoma (FTCL) as
      defined in the 2016 revision of the WHO classification of lymphoid malignancies.

             measurable disease site using criteria provided in section 11.

          -  Relapsed or refractory (R/R) disease, after at least 2 prior systemic drug treatment
             regimens (oral bexarotene, interferon, any oral or IV HDAC inhibitor, any oral or IV
             chemotherapy drug). For CD30-expressing diseases for which brentuximab vedotin (BV) is
             approved, patients should have relapsed or refractory disease to BV or a BV-containing
             regimen or have either intolerance or contraindication to BV. For purpose of this
             study, total body electron beam radiation is not considered a systemic regimen. There
             is no upper limit on prior therapy.

          -  Refractory disease is defined as lack of objective response (i.e., partial or complete
             response) to most recent therapy.

          -  Relapsed disease is defined as recurrent disease after prior therapy that does not
             qualify as refractory disease.

          -  For primary cutaneous lymphomas, stage IB, II, III and IV according to the TNMB system
             are eligible. For primary nodal lymphomas, patients with stages II-IV according to the
             Ann Arbor staging system are eligible.

          -  Minimum of 4 weeks must have elapsed since last systemic treatment or radiation
             therapy (or 6 weeks for any nitrosourea-containing regimens), and patients must have
             recovered from all toxicity of last treatment.

          -  Age ≥18 years. Both genders are included. However, women of childbearing potential
             must have a negative urine pregnancy test (UPT) and agree to use an effective
             contraceptive method for the duration of the study. Lactating women are excluded. Male
             patients with significant others of childbearing age should also agree to use barrier
             methods of contraception for the duration of therapy

          -  ECOG performance status 0-1 (Karnofsky ≥60%).

          -  Life expectancy greater than 6 months.

               3. Platelets ≥ 100,000/μL

               4. Total bilirubin within normal institutional limits. Patients with total bilirubin
                  ≤ 1.5 X upper limit of normal are eligible

               5. AST (SGOT) and ALT (SGPT) within institutional upper limit of normal

               6. Creatinine clearance ≥60 mL/min/1.73m^2 by the Modification of Diet in Renal
                  Disease (MDRD) equation

          -  Triglyceride blood level (fasting) <200mg/dL at time of enrollment (normal: <150mg/dL;
             borderline high = 150-199mg/dL; high = 200-499mg/dL; very high = 500mg/dL or higher).

          -  The effects of ST-001 nanoFenretinide on the developing human fetus are unknown. For
             this reason and because of the teratogenic effects of retinoids, women of childbearing
             potential and men must agree to use adequate contraception (hormonal or barrier method
             of birth control; abstinence) prior to study entry and for the duration of study
             participation, as well as for 4 months after completion of ST-001 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 enrollment in the study, for the duration of study participation, and 4
             months after completion of ST-001administration.

          -  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.

          -  Patients who are receiving any other investigational agents.

          -  Patients with known or history of central nervous system (CNS) disease are excluded
             from this clinical trial because of their poor prognosis and because of concerns
             regarding toxicity attribution.

          -  History of allergic reactions or sensitivity to retinoids or to any excipients of
             ST-001.

          -  Concomitant drug administration.

          -  Patients who require concurrent treatment with drugs that are strong CYP3A inducers
             are excluded from the trial. Patients who have been treated previously with strong
             CYP3A inducers may enroll in the trial and receive their first dose of ST-001 only
             after four weeks have elapsed since the last dose of the CYP3A inducer. Strong
             inducers of human CYP3A include barbiturates, bosentan, carbamazepine, efavirenz,
             enzalutamide, etravirine, systemic glucocorticoids, mitotane, modafinil, nevirapine,

          -  Patients who require concurrent treatment with drugs that are strong to moderate CYP3A
             inhibitors are excluded from the trial, and patients who have been treated previously
             with strong CYP3A inhibitors may enroll in the trial and receive their first dose of
             ST-001 only after four weeks have elapsed since the last dose of the CYP3A inhibitor.
             This group of inhibitors includes certain antivirals (boceprevir, danoprevir,
             paritaprevir; elvitegravir, indinavir, lopinavir, nelfinavir, ritonavir, saquinavir,
             telaprevir, tipranavir; ombitasvir, dasabuvir), macrolide antibiotics (e.g.,

          -  If patients being treated with ST-001 require the use of drugs that are either strong
             inducers of CYP3A or strong to moderate inhibitors of CYP3A to treat a medical
             condition, all treatment with ST-001 should be discontinued immediately and no further
             treatment with ST-001 will be allowed.

          -  Use of acetaminophen, cephalosporins and other known hepatotoxic agents is allowed
             with caution and close monitoring, due to known or potential interaction with ST-001
             and potential increased risk of hepatotoxicity. Because the lists of these agents are
             constantly changing, it is important to regularly consult a frequently updated list
             such as http://medicine.iupui.edu/clinpharm/ddis/. Medical reference texts such as the
             Physicians' Desk Reference may also provide this information.

          -  As part of the enrollment/informed consent procedures, the patient will be counseled
             on the risk of interactions with other agents, and what to do if new medications need
             to be prescribed or if the patient is considering a new over-the-counter medicine or
             herbal product. Physician investigators should consult the websites listed above for
             the most current information regarding drug interactions via CYP3A isozymes.

          -  Use of vitamin A supplements is prohibited. Standard multivitamin doses are allowed.

          -  Uncontrolled intercurrent illness including, but not limited to, ongoing or active
             infection, symptomatic congestive heart failure (NY heart classification III/IV),
             unstable angina pectoris, cardiac arrhythmia, QTc interval >450 milliseconds on
             baseline triplicate ECG, or psychiatric illness/social situations that would limit
             compliance with study requirements.

          -  Pregnant women are excluded from this study because ST-001is a retinoid agent with 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 ST-001, breastfeeding should be discontinued if the mother is treated with
             ST-001.

          -  HIV-positive patients on combination antiretroviral therapy are ineligible because of
             the potential for pharmacokinetic interactions with ST-001. Appropriate studies will
             be undertaken in patients receiving combination antiretroviral therapy when indicated.

          -  Patients with any active hepatitis infections.

          -  Presence of nyctalopia (night blindness), or hemeralopia (defective vision in a bright
             light, 'day blindness') at enrollment, or any other retinal, ophthalmological
             condition (eg: retinitis pigmentosa, choroidoretinitis and xerophthalmia), and
             glaucoma.

          -  Patients who have received prior fenretinide systemic therapy

          -  Patients with T-cell lymphoma types other than those specified in section 3.1.1 are
             not eligible even if they have cutaneous dissemination. Similarly, patients with any
             type of natural killer (NK)- or B-cell lymphoma are not eligible regardless of sites
             of involvement by disease.
      
Maximum Eligible Age:N/A
Minimum Eligible Age:18 Years
Eligible Gender:All
Healthy Volunteers:No

Primary Outcome Measures

Measure:Maximum Tolerated Dose (MTD)
Time Frame:12 months
Safety Issue:
Description:To determine the MTD of ST-001 nanoFenretinide (12.5mg/mL) for IV infusion in patients with CTCL and other T-cell NHL.

Secondary Outcome Measures

Measure:Number of participants with treatment-related adverse events as assessed by CTCAE v4.0
Time Frame:12 months
Safety Issue:
Description:The number of participants with treatment-related adverse events as assessed by NCI CTCAE v4.0 will be determined. All patients who receive any dose of ST-001 will be evaluable for toxicity. The incidence rates of adverse events (AEs) will be tabulated by system organ class and preferred term, and by severity. All AEs with corresponding attributes will be displayed in a by-patient listing. The investigator at each site will determine the causal relationship between study medication and AEs. Subsets of AEs to be summarized include Severe Adverse Events (SAEs), suspected treatment-related AEs, and AEs that resulted in withdrawal of treatment or death.
Measure:Number of participants with complete response (CR) or partial response (PR) to ST-001
Time Frame:24 months
Safety Issue:
Description:Any patient who has at least one measurable disease site and has received at least on full cycle (5-day infusion) of ST-001 is eligible for response-to-treatment evaluation. The frequency and proportion of subjects with CR or PR will be calculated with a 95% Clopper Pearson confidence interval. CR + PR will constitute the overall response rate (ORR). The Global Response Scale (GRS) will be used to determine response of CTCL patients to ST-001. The GRS incorporates all components of the TNMB system (skin, lymph nodes, viscera, and blood). The International Working Group (IWG) Criteria for Response Assessment will be used to determine response in non-CTCL T-NHL patients.
Measure:Fenretinide Cp(plateau), half-life (t1/2), and calculated parameters of Clearance and Volume of Distribution
Time Frame:18 months
Safety Issue:
Description:Pharmacokinetic (PK) evaluation of fenretinide Cp X t curves, Cp(plateau), and half-life (t1/2) as well as calculated parameters of Clearance and Volume of Distribution will be conducted at each dose level when all of its planned first cycle treatments have been completed. PK analysis will use descriptive statistics to characterize the range, median, and mean of calculated values of fenretinide clearance, volume of distribution, and distribution and elimination phase half-lives across all evaluable patients using individual patient C X t data. The relationship between dose and CpMAX and/or AUC will be examined as will their relationship to grade of toxicity.
Measure:Activation of cytolytic T-lymphocytes (CTLs) and natural killer (NK) cells after ST-001 treatment.
Time Frame:24 months
Safety Issue:
Description:The pharmcodynamic (PD) effect of ST-001 will be evaluated in tissue biopsies taken from tumorous skin lesions of CTCL patients. CTL and NK cell activation will be measured by expression of granzyme A and B, perforin, and NKG2D using immunohistochemical staining (IHC) of tissue biopsies. In addition, CTLs and NK cell tumor infiltration will be evaluated using CD8 and CD56 IHC staining, respectively. Biomarker analysis will use each patient's baseline (pre-treatment) values as the Control value and normalize PD changes as % change from baseline. In addition, the baseline PD biomarker values across all evaluable patients will be characterized as a distribution, and the on-treatment PD responses analyzed for values that are statistical outliers from the baseline distribution of values.
