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

RECRUITINGMaximum Tolerated Dose (MTD)
To determine the MTD of ST-001 nanoFenretinide (12.5mg/mL) for IV infusion in patients with CTCL and other T-cell NHL.
Time frame: 12 months
Number of participants with treatment-related adverse events as assessed by CTCAE v5.0
The number of participants with treatment-related adverse events as assessed by NCI CTCAE v5.0 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.
Time frame: 12 months
Number of participants with complete response (CR) or partial response (PR) to ST-001
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.
Time frame: 24 months
Fenretinide Cp(plateau), half-life (t1/2), and calculated parameters of Clearance and Volume of Distribution
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.
Time frame: 18 months
Activation of cytolytic T-lymphocytes (CTLs) and natural killer (NK) cells after ST-001 treatment.
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.
