Should l Buy CTOR?
Citius Oncology announced positive topline results from a completed investigator-initiated Phase1 clinical trial evaluating the direct T-regulatory, or Treg, cell depletion activity of lymphir - denileukin diftitox-cxdl - in combination with the PD-1 immune checkpoint inhibitor pembrolizumab - Keytruda - in patients with recurrent or refractory gynecologic cancers, including ovarian and endometrial malignancies. Patients with relapsed or refractory gynecological cancer have poor prognoses and very limited treatment options. This dose-escalation Phase 1 non-chemotherapy based clinical study aimed to establish a recommended dose of lymphir in combination with pembrolizumab for a Phase 2 study. In 25 evaluable patients, no unexpected safety signals or serious immune-related adverse events were observed at any dose level. The trial explored efficacy and demonstrated a 24% objective response rate and a 48% clinical benefit rate among 21 evaluable patients. Full safety and clinical efficacy results are expected to be presented at an international cancer conference later this year.

Analyst Views on CTOR
About CTOR
Citius Oncology, Inc. is a biopharmaceutical company. The Company is focused on developing and commercializing targeted oncology therapies. The Company’s lead product candidate is LYMPHIR, an engineered IL-2 diphtheria toxin fusion protein, for the treatment of patients with persistent or recurrent CTCL, a rare form of non-Hodgkin lymphoma. LYMPHIR is a targeted immune therapy for relapsed or refractory cutaneous T-cell lymphoma (CTCL) indicated for use in Stage I-III disease after at least one prior systemic therapy. It is a recombinant fusion protein that combines the IL-2 receptor binding domain with diphtheria toxin fragments. The agent specifically binds to IL-2 receptors on the cell surface, causing diphtheria toxin fragments that have entered cells to inhibit protein synthesis. After uptake into the cell, the diphtheria toxin (DT) fragment is cleaved and the free DT fragments inhibit protein synthesis, resulting in cell death.

LYMPHIR Shows Promise in Gynecologic Cancer Treatment
- Clinical Trial Results: The Phase 1 trial led by the University of Pittsburgh demonstrated that LYMPHIR combined with KEYTRUDA showed no unexpected safety signals in 25 patients, indicating a favorable safety profile that could offer new treatment options for difficult-to-treat gynecologic cancers.
- Efficacy Assessment: Among 21 evaluable patients, the combination therapy achieved a 24% objective response rate (ORR) and a 48% clinical benefit rate (CBR), highlighting the potential of this combination to enhance anti-tumor activity and warranting further investigation.
- Market Potential: LYMPHIR is estimated to have a market potential exceeding $400 million, and as demand for novel therapies increases, Citius Oncology's competitive positioning in oncology will be further strengthened, particularly in the ovarian cancer sector where immunotherapy has had limited impact.
- Future Research Plans: Citius Oncology intends to explore the efficacy of LYMPHIR in subsequent Phase 2 studies, and if results are confirmed, it could provide a transformative treatment option for gynecologic cancer patients, significantly improving patient outcomes.

Citius Oncology Reports Positive Phase 1 Trial Results for LYMPHIR in DLBCL
- Clinical Trial Response Rate: The LYMPHIR clinical trial conducted at the University of Minnesota and City of Hope demonstrated an 86% overall response rate, including a 57% complete response and a 29% partial response, indicating the potential efficacy of LYMPHIR in patients with high-risk relapsed DLBCL, which may provide new treatment options in the future.
- Good Safety Profile: LYMPHIR exhibited a favorable safety profile in the trial, with no dose-limiting toxicities observed, laying a solid foundation for its clinical application and potentially enhancing patient acceptance and adherence to treatment.
- Enhancing CAR-T Therapy: The use of LYMPHIR aims to augment the anti-tumor activity of CAR-T cell therapies by improving T-cell depleting effects, which could increase the effectiveness of existing treatment regimens and advance the field of tumor immunotherapy.
- Future Research Directions: The findings set the stage for larger clinical trials, with Citius Oncology planning to further explore the combination of LYMPHIR with other therapies to enhance treatment efficacy and improve long-term patient outcomes.

Citius Oncology Reports Positive Phase 1 Trial Results for LYMPHIR in DLBCL
- Trial Results: The investigator-initiated study of LYMPHIR™ (E7777) at the University of Minnesota and City of Hope demonstrated an overall response rate (ORR) of 86%, including 57% complete responses (CR) and 29% partial responses (PR), indicating its potential efficacy in high-risk relapsed or refractory diffuse large B-cell lymphoma (DLBCL) patients.
- Safety Profile: LYMPHIR was well tolerated in the trial, with no dose-limiting toxicities (DLTs) observed, as all 14 patients completed treatment and proceeded to CAR-T infusion, highlighting its favorable safety profile without any Grade ≥3 immune adverse events reported.
- Treg Depletion Effect: A single dose of LYMPHIR resulted in Treg depletion in nearly all patients, with a median reduction of 24 Tregs/µL, suggesting its potential to enhance standard lymphodepletion regimens and improve the anti-tumor activity of CAR-T therapies.
- Future Research Directions: These findings set the stage for larger studies to assess the potential of LYMPHIR to enhance CAR-T efficacy through prolonged use, further advancing Citius Oncology's strategic positioning in the field of cancer immunotherapy.
