High grade B-cell lymphoma

Company’s first clinical trial studying CAR-NK (CD19 t-haNK) cellular therapy in liquid tumors First natural killer cell-based cellular therapy study conducted in the continent of Africa Complete enrollment currently expected in Q1 2025 CULVER CITY, Calif.--(BUSINESS WIRE)--Immunotherapy innovator ImmunityBio, Inc. ( NASDAQ: IBRX ), announced today that the first patients have been dosed in an initial trial studying the potential of the company’s CAR-NK cell therapy targeting CD-19 in the treatment of non-Hodgkin’s lymphoma (NHL). In the QUILT 106 trial, CD19-targeted high-affinity natural killer (t-haNK) cells are being tested initially as a single agent, and after demonstrating safety, then in combination with standard NHL treatment rituximab, in participants with selected CD19+ and CD20+ relapsed/refractory B-cell NHL. The phase 1, open label clinical study is designed to enroll up to 10 participants and is being conducted in Johannesburg, Pretoria, and Bloemfontein, South Africa. This is the first cellular-targeted natural killer (NK) cell therapy study ever to be conducted in South Africa, and is designed to provide important clinical information on a cancer with a significant rate of diagnosis in the region, but with few treatment options. Non-Hodgkin’s lymphoma is the 6 th most common malignancy among people in Sub-Saharan Africa and it is the 4 th most diagnosed cancer in men and the 5 th most diagnosed cancer in women in South Africa, according to the Cancer Association of South Africa. “This trial is important for ImmunityBio as our first clinical study of our CAR-NK, CD19 t-haNK cell line, as well as one of our first studies in liquid tumors,” said Patrick Soon-Shiong, M.D., Executive Chairman, Founder and Global Chief Scientific and Medical Officer at ImmunityBio. “We have chosen to undertake this trial because Sub-Saharan African and, in particular, South African populations are often overlooked when it comes to advanced clinical research, despite the need for innovative immunotherapies in the region.” Full patient enrollment in this Phase 1 study of CD19 t-haNK is currently expected in the first quarter of calendar year 2025 with topline data readout expected in the second half of the calendar year 2025. This study, being conducted in South Africa, is similar to ImmunityBio’s U.S.-based trial QUILT 3.092, a phase 1 open-label study of CD19 t-haNK as a single agent and in combination with the company’s IL-15 superagonist (N-803; ANKTIVA®) and rituximab in participants with relapsed or refractory NHL. About the QUILT 106 Study The Phase 1, first-in-human (FIH), open-label study is designed to enroll up to 10 participants at sites in Johannesburg, Pretoria, and Bloemfontein, South Africa with the primary endpoint of the trial to evaluate the safety and preliminary efficacy of CAR-NK, CD19 t-haNK as a single agent and in combination with rituximab in participants with selected CD19+ and CD20+ R/R B-cell non-Hodgkin lymphoma (NHL). Participants will initially receive a single 3-week cycle of the CD19 t-haNK as a single-agent regime. Following a 1-week safety pause, participants will then receive a 3-week cycle of CD19 t-haNK in combination with rituximab. Patients will undergo multiple assessments of safety and efficacy to help evaluate the safety of CD19 t-haNK as a single agent and in combination with rituximab in participants with R/R NHL, who have active disease after completing ≥ 2 lines of cytotoxic chemotherapy. About CAR-NK, CD19 t-haNK CD19 t-haNK is a human, allogeneic, stable clonal NK cell line generated from the parental activated NK (aNK) cell line (NK-92). Based on the demonstrated therapeutic efficacy of chimeric antigen receptor (CAR) targeting and on the important role of FcγR-mediated antibody-dependent cellular cytotoxicity (ADCC) in the effectiveness of therapeutic IgG1 monoclonal antibodies, it was hypothesized that modification of the parental aNK cell line to stably express both a CD19-targeted CAR and the high-affinity variant of CD16 would result in potent and selective antitumor activity. Therefore, the novel CD19 t-haNK cells have been genetically engineered to stably express 3 main proteins: (1) a human CD19-targeted CAR; (2) the high-affinity variant of the human Fcγ receptor (FcγRIIIa/CD16a 158V) for enhanced ADCC; and (3) endoplasmic reticulum-retained version of human interleukin-2 (ERIL-2) for independent growth. Non-Hodgkin Lymphoma Non-Hodgkin lymphoma (NHL) is a heterogeneous disease that most commonly originates in B lymphocytes. In 2020, according to the South Africa National Cancer Registry ( SANCR 2020 ), it is estimated that 1 in 174 men and 1 in 288 women will develop NHL. According to Global Cancer Observatory ( Sung 2021 ), the incidence of NHL is 4.1% of all cancers. A comparative study of the distribution of NHL subtypes in South Africa reported that Southern Africa had a significantly lower proportion of low-grade B cell NHL (34.3%) and a higher proportion of high-grade B cell NHL (51.5%) compared to Western Europe (54.5% and 36.4%) and North America (56.1% and 34.3%) ( Perry 2015 ).

VIP943 demonstrates promising safety and tolerability and achieves two complete responses to date in Phase 1 dose-escalation study, reinforcing the program’s potential and validating the VersAptx™ Platform technology Vincerx focusing resources on continued development of VIP943 Expected cash runway into early 2025 Management to host webcast and Q&A today at 5:00 PM EDT to review pipeline and corporate updates, followed by commentary from key opinion leader Dr. M. Yair Levy Oct. 07, 2024 -- Vincerx Pharma, Inc. (Nasdaq: VINC), a biopharmaceutical company aspiring to address the unmet medical needs of patients with cancer through paradigm-shifting therapeutics, announced two complete responses in the ongoing first-in-human, Phase 1 dose-escalation study of VIP943, the Company’s next-generation antibody-drug conjugate (ADC) being evaluated in relapsed/refractory acute myeloid leukemia (AML), higher-risk myelodysplastic syndrome (HR-MDS), and B-cell acute lymphoblastic leukemia (B-ALL). The Company also provided pipeline and corporate updates. The ongoing Phase 1 dose-escalation study of VIP943 has enrolled 22 patients to date across several escalating dose cohorts (0.2 to 1.3 mg/kg once weekly). These 22 patients represent a ‘hard-to-treat’ salvage population, which rarely responds to monotherapy. Nine patients (six AML; three HR-MDS) have received at least three doses of an efficacious dose of VIP943 (i.e., ≥1.0 mg/kg). Of these nine patients, four (44%) remain on study. So far, one patient with relapsed AML has achieved complete remission with incomplete hematologic improvement (CRi) and one patient with HR-MDS has achieved complete remission with limited count recovery (CRL) based on international consensus response criteria. These response criteria are widely recognized as an approvable benchmark in AML and MDS studies, further underscoring the significance of these early results. “We are excited by the emerging data from our Phase 1 study of VIP943, showing clinical responses in difficult-to-treat patients," said Ahmed Hamdy, M.D., Chief Executive Officer of Vincerx. "We believe these promising clinical responses highlight the potential of VIP943 as a best-in-class therapy for CD123+ hematologic malignancies and validate our VersAptx platform’s ability to create safer, more effective bioconjugates by overcoming the challenges of historical ADCs.” As of August 2024, VIP943 has shown favorable safety and tolerability, with no dose-limiting toxicities reported in 22 patients. Serious adverse events (SAEs) have been consistent with expectations for this patient population. The most common SAEs included pneumonia (three patients, 14%), and cellulitis and febrile neutropenia (two patients each, 9%). Only one patient (5%) experienced a drug-related SAE (Grade 3 diarrhea). Target engagement (i.e., receptor occupancy) has been demonstrated by binding of VIP943 to CD123+ peripheral blood blasts from patients with AML from the Phase 1 study. Maximal receptor occupancy of 84% was achieved in the highest dose cohort (1.3 mg/kg). Across all the cohorts, receptor occupancy was retained for less than 96 hours. Concurrent decreases in CD123+ peripheral blood blasts were also observed after dosing. These pharmacodynamic (PD) markers show that VIP943 is binding to and eliminating CD123+ malignant cells. Preliminary pharmacokinetic (PK) data continues to show low release of payload (≤1% in plasma). The half-life of VIP943 is less than 96 hours, and no accumulation occurs with repeat dosing. These PK and PD results have prompted evaluation of twice weekly dosing of VIP943 as a potential “induction” regimen. Enrollment in the once weekly and twice weekly dosing cohorts is ongoing. Dr. Hamdy continued, “Our initial clinical results demonstrate that VersAptx is a next-generation platform that overcomes key challenges associated with traditional ADCs. The PK profile shows that our linker is stable, cleaving exclusively inside cells without extracellular degradation. Our PD results coupled with clinical responses confirm the payload effectively kills cancer cells in peripheral blood and bone marrow without harming nearby healthy tissue. This innovative design with proof-of-concept in Phase 1 reinforces our confidence in VersAptx as a transformative platform for ADC development.” The company anticipates providing another data update on the ongoing Phase 1 VIP943 study by the end of the year. Dr. M. Yair Levy, Director of Hematologic Malignancies Research at Texas Oncology added, "Although this is still early data, VIP943 is clearly differentiated from other ADCs, particularly with its favorable safety profile. We’re not seeing neutropenia as a dose-limiting toxicity, which is encouraging and may allow the drug to move into earlier lines of therapy in combination. I look forward to the continued development of VIP943 and its potential to improve treatment options for patients with CD123+ malignancies.” VIP236 is Vincerx’s first-in-class small molecule drug conjugate (SMDC) being evaluated in an ongoing first-in-human, Phase 1 dose-escalation study as a monotherapy in patients with advanced solid tumors. As of September 2024, 29 patients have been enrolled. Of these patients, 20 were evaluable per-protocol for response from the every 2- or 3-week schedule; nine of 20 patients had stable disease for a disease control rate of 45%. In addition, one of these subjects has been on treatment for over 300 days and four additional patients were on study for more than 120 days, demonstrating promising monotherapy duration of response in patients with advanced cancer. VIP236 continued to show a favorable safety and tolerability profile in these 29 patients, with no instances of the dose-limiting side effects commonly associated with camptothecins, such as life-threatening diarrhea, severe stomatitis/mucositis, or interstitial lung disease. These results support the potential role of VIP236 as a strong combination agent for the treatment of advanced cancers. Considering the promising VIP236 clinical data, the Company intends to pursue a strategic partner to champion its future development for the benefit of patients. “We've made significant progress in identifying an effective dose and schedule. We believe it is now crucial to study VIP236 in the right patient population, which could include triple-negative breast cancer and gastric cancer, where camptothecins are used, especially in combination with other anticancer agents,” added Dr. Hamdy. By transitioning VIP236 to a partnering asset, the Company plans to streamline its operations and focus its efforts on the continued development of its lead ADC, VIP943. Enitociclib, a highly selective CDK9 inhibitor, is currently being evaluated in a Phase 1 dose-escalation study in combination with venetoclax and prednisone for relapsed/refractory diffuse large B-cell lymphoma (DLBCL) and peripheral T-cell lymphoma (PTCL), in collaboration with the National Institutes of Health (NIH). As of September 2024, the study reported four partial responses (PRs) in seven patients (57% overall response rate), including one patient with double hit lymphoma (DH-DLBCL) and three patients with PTCL. All responses occurred in patients considered refractory by SCHOLAR-1 criteria and included one patient with prior CAR-T therapy. The study is currently enrolling in the third dose level (enitociclib 30 mg [efficacious dose] and venetoclax 600 mg) with two patients enrolled to date. Additionally, in a separate Phase 1 study of enitociclib as a monotherapy (30 mg), one patient with transformed follicular lymphoma achieved a metabolic PR. As of September 2024, this patient remains on enitociclib monotherapy after more than 26 months. Overall, these clinical results continue to show the promising safety, tolerability, and efficacy of enitociclib for the treatment of relapsed/refractory lymphoma. The Company is actively focused on finding a strategic partner to continue the development of this asset. VIP236, the first-in-class SMDC from the VersAptx Platform, consists of an αvβ3 integrin binder, a neutrophil elastase linker cleaved in the tumor microenvironment, and a camptothecin payload optimized for high permeability and low active efflux. VIP236 was designed to deliver its payload to advanced/metastatic solid tumors that express αvβ3. VIP236 is being evaluated in a first-in-human, Phase 1 dose escalation study in patients with advanced malignancies (NCT05712889). VIP943, the first ADC from the VersAptx platform, consists of an anti-CD123 antibody, a unique linker cleaved intracellularly by legumain, and a novel kinesin spindle protein inhibitor (KSPi) payload enhanced with Vincerx’s CellTrapper™ technology. Vincerx’s proprietary effector chemistry (linker + payload) was designed to reduce non-specific release of the payload and ensure payload accumulation in cancer cells versus healthy cells. The increased therapeutic index has the potential to address challenges associated with many ADCs by improving efficacy and reducing severe toxicities. VIP943 is being evaluated in a Phase 1 dose-escalation trial in patients with relapsed/refractory AML, HR-MDS, and B-ALL who have exhausted standard therapeutic options (NCT06034275). Enitociclib, a highly selective CDK9 inhibitor, is currently being evaluated in a Phase 1 dose-escalation study (NCT05371054) in combination with venetoclax and prednisone for DLBCL and PTCL, in collaboration with the NIH. Enitociclib has demonstrated favorable safety and PK, with significant clinical benefits across various indications, including durable complete metabolic remissions in patients with double-hit (DH)-DLBCL and stable disease in solid tumors, notably in ovarian cancer, suggesting promising potential for future combination studies.
