DIFFERENTIATED MECHANISM OF ACTION (MOA) LYMPHIR targets the IL - 2 receptor, working both as a targeted therapy against malignant T - cells AND as an immunotherapy against Tregs IL - 2 receptor offers a unique treatment opportunity in CTCL Malignant T - cells and Tregs share a common marker: the IL - 2 receptor Targets Malignant Cells Binds to IL - 2 receptors to deliver diphtheria toxin, killing tumor cells directly NASDAQ: CTXR 9 Eliminates Immunosuppressive Tregs Reduces number of Treg cells, subsequently enhancing anti - tumor immunity

COMPETITIVE LANDSCAPE Today’s CTCL treatments are non - curative LYMPHIR excels where current therapies are limited • Requires CD30+ biomarker • Peripheral neuropathy may limit use • Most effective in SS subsegment of CTCL (<5%) • Acts on blood disease rather than skin disease • ORR 21% in MF • Use limited by cumulative bone marrow toxicity • Quality of life issues • No biomarker needed • Broad label • No cumulative toxicity • Skin relief • Rapid response • No cumulative toxicity • No cumulative toxicity • Refined patient profile Limitations NASDAQ: CTXR 10

MARKET POTENTIAL: $1B+ IN US AND $2B+ GLOBALLY High incidence of catheter - related infections support need for effective treatment options ~500,000 CRBSI/CLABSI infections annually in the U.S.** 12 - 25% CRBSI/CLABSI associated mortality & morbidity** * Shah H., Bosch W., Hellinger W. C., Thompson K. M. (2013). Intravascular catheter - related bloodstream infection. Neurohospitalist 3, 144 – 151. doi: 10.1177/1941874413476043. ** Antoňáková Němčíková A, Bednárovská E.

NASDAQ: CTXR 21 4 million Long - term CVCs (>1 month) in the U.S.* 7 million Central Venus Catheters (CVCs) used annually in the U.S.*

POTENTIAL TO CHANGE STANDARD OF CARE Mino - Lok addresses the complications, discomfort and cost of CVC removal and replacement salvage existing catheters Limited duration IV therapy designed to eradicate bacterial colonization with a short 2 - hour dwell time Limits disruption of infusion therapy allowing continued use of the catheter for intended treatments Ease of Administration: Locking a catheter is a well - known standard operating procedure Non - invasive and adjunct to systemic therapy Lowers risks to patient Lower cost alternative: significantly less than removal and replacement NASDAQ: CTXR 22

MINO - LOK PHASE 3 TRIAL TOPLINE RESULTS NASDAQ: CTXR 23 Mino - Lok significantly outperforms hospital - specific anti - infective lock solutions • Kaplan Meier Analysis demonstrated clear separation between Mino - Lok and control arms, illustrating Mino - Lok’s superiority in extending time to catheter failure Control arm: 33 days Mino - Lok arm: exceeded the trial period (6 weeks) (p - value = 0.0006) Primary Endpoint: Median Time to Failure A greater percentage of patients in the Mino - Lok arm achieved overall treatment success compared to the control arm (p - value = 0.0025) Key Secondary Endpoint: Overall Treatment Success Mino - Lok was well - tolerated with no drug - related serious adverse events Comparable adverse events between Mino - Lok (45.1%) and control (46.1%) arms, as expected in very ill patients Mino - Lok is instilled into the catheter and never enters the patient Safety Profile
