QuantumpBac: An effective, high‐capacity piggyBac‐based gene integration vector system for unlocking gene therapy potential

Article

Author: Wu, Sareina Chiung‐Yuan ; Hsu, Jeff C. ; Wen, Kuo‐Lan Karen ; Chen, Ying‐Chun ; Chang, Peter S. ; Shen, Chia‐Ning ; Hua, Wei‐Kai ; Wang, Po‐Nan ; Yu, Yi‐Shan ; Cheng, I‐Cheng ; Yang, Wei‐Cheng ; Chen, Yi‐Chun

Abstract:

Recent advances in gene therapy have brought novel treatment options for cancer. However, the full potential of this approach has yet to be unlocked due to the limited payload capacity of commonly utilized viral vectors. Virus‐free DNA transposons, including piggyBac, have the potential to obviate these shortcomings. In this study, we improved a previously modified piggyBac system with superior transposition efficiency. We demonstrated that the internal domain sequences (IDS) within the 3′ terminal repeat domain of hyperactive piggyBac (hyPB) donor vector contain dominant enhancer elements. Plasmid‐free donor vector devoid of IDS was used in conjunction with a helper plasmid expressing Quantum PBase™ v2 to generate an optimal piggyBac system, Quantum pBac™ (qPB), for use in T cells. qPB outperformed hyPB in CD20/CD19 CAR‐T production in terms of performance as well as yield of the CAR‐T cells produced. Furthermore, qPB also produced CAR‐T cells with lower donor‐associated variabilities compared to lentiviral vector. Importantly, qPB yielded mainly CD8+ CAR‐TSCM cells, and the qPB‐produced CAR‐T cells effectively eliminated CD20/CD19‐expressing tumor cells both in vitro and in vivo. Our findings confirm qPB as a promising virus‐free vector system with an enhanced payload capacity to incorporate multiple genes. This highly efficient and potentially safe system will be expected to further advance gene therapy applications.

Loop CD20/CD19 CAR-T cells eradicate B-cell malignancies efficiently

Article

Author: Xu, Yingxi ; Chen, Zhaoqi ; Tian, Zheng ; Tang, Kejing ; Wang, Min ; Chen, Nianci ; Xing, Haiyan ; Rao, Qing ; Wang, Ying ; Wang, Jianxiang ; Liu, Yan

CD19 chimeric antigen receptor (CAR) T cells have shown robust efficacy in relapsed and refractory acute lymphoblastic leukemia (R/R ALL), but compromising result in chronic lymphoblastic leukemia (CLL) and non-Hodgkin's lymphoma (NHL). CD19 relapse and the lack of CAR-T cell persistence which result in treatment failure are considerable obstacles to overcome. CAR-T targeting CD20 is an option for salvaging CD19 CAR-T failure. Previous studies have established variant structures of bispecific CAR-T which could avoid antigen-loss and immune escape. Here, we constructed tandem and loop CAR structures targeting both CD19 and CD20 antigen. Bispecific CAR-T cells could eliminate either CD19 or CD20 negative lymphoma cells, suggesting they exhibited dual antigen targeting of CD19 and CD20. By comparing the efficiency of four bispecific CAR modified T cells, it was found that loop2019 CAR was the best structure among them to eradicate lymphoma cell lines and patients' primary lymphoma or CLL cells in a very low dose in vitro and prolong the survival time dramatically in lymphoma xenograft mice model. These data highlighted the potential of loop2019 CAR-T in clinical treatment.

Follicular Lymphoma Clinical Trial Pipeline Appears Robust With 50+ Key Pharma Companies Actively Working in the Therapeutics Segment | DelveInsight

Advances in immunotherapy have ushered in a new era of treatment for follicular lymphoma (FL), particularly for patients who have experienced relapse after conventional chemotherapy regimens. This paradigm shift is characterized by the emergence of innovative therapies like CAR T-cell therapy and bispecific antibodies, which have demonstrated remarkable efficacy in targeting and eradicating lymphoma cells. CAR T-cell therapy represents a groundbreaking approach where a patient's own T-cells are genetically engineered to recognize and attack cancer cells. This personalized treatment has shown significant promise, especially for individuals who have undergone extensive previous therapies. One notable example is Axicabtagene ciloleucel (Yescarta), a CAR T-cell therapy approved for use in patients with relapsed or refractory follicular lymphoma. Clinical trials have highlighted its ability to induce durable remissions, with some patients experiencing long-term remission even after multiple prior therapies.

Follicular Lymphoma Overview Follicular lymphoma is a common type of non-Hodgkin lymphoma (NHL) that originates from B-cells, a kind of white blood cell responsible for producing antibodies. This cancer is characterized by the growth of abnormal lymphoid follicles, which can disrupt normal lymphatic function. While the exact causes of follicular lymphoma are not fully understood, certain factors may increase the risk, including age (most commonly affecting adults over 60), a family history of lymphoma, and potential environmental factors such as exposure to pesticides or chemicals. Symptoms of follicular lymphoma can vary widely but may include painless swelling of lymph nodes in the neck, armpit, or groin, unexplained weight loss, night sweats, fatigue, and fever. Some patients may remain asymptomatic for extended periods, as this type of lymphoma can progress slowly. Diagnosis typically involves a combination of physical examinations, blood tests, imaging studies (like CT scans), and a biopsy of affected lymph nodes. The biopsy helps determine the subtype and stage of the lymphoma, which is crucial for planning treatment. Treatment for follicular lymphoma depends on the stage of the disease and the patient's overall health. Options may include watchful waiting for asymptomatic cases, chemotherapy, immunotherapy (such as monoclonal antibodies), and targeted therapies. In some cases, stem cell transplants may be considered for patients with more aggressive forms or those who do not respond to initial treatments. Given the indolent nature of follicular lymphoma, ongoing management, and regular monitoring are vital for achieving the best possible outcomes.

C-CAR066 is an optimized, novel CD20 targeted CAR-T therapy that has also received U.S. FDA IND clearance, and a Phase 1b study in patients with r/r DLBCL, including r/r to CD19 CAR-T treatment, is underway in the U.S. About NHL and DLBCL Non-Hodgkin Lymphoma (NHL) is the most common hematological, or blood malignancy worldwide. NHL ranked as the 5th to 9th most common cancer in most countries globally, with an estimated 544,000 new cancer cases and 260,000 cancer deaths in 2020.1 Diffuse large B-cell lymphoma (DLBCL) is a common and aggressive form of non-Hodgkin lymphoma that accounts for one out of every three cases of NHL. Despite available frontline treatment, many patients will experience a relapse or have refractory (resistant to treatment) disease, for which there are limited treatment options and a high risk of mortality. For patients who relapse or do not respond to initial therapies, conventional treatment options that provide durable remission are limited and median life expectancy is about six months, leaving a critical need for new therapies.2,3 Mafra A, Laversanne M, Gospodarowicz M, Klinger P, De Paula Silva N, Piñeros M, Steliarova-Foucher E, Bray F, Znaor A.

C-CAR039 has consistently shown ability to eradicate CD19/CD20 single or double positive tumor cells in vitro and in vivo. GMP manufacturing of C-CAR039 was carried out in a serum free and fully closed semi-automatic system. In the Phase I clinical trials in China (NCT04317885, NCT04655677, NCT04696432, NCT04693676), dose escalation and expansion studies were conducted to evaluate the safety and efficacy of C-CAR039 in r/r B-NHL patients. C-CAR039 was administered as a single intravenous dose after a 3-day cyclophosphamide (300mg/m2x3d) plus fludarabine (30mg/m2x3d) conditioning regimen. Key Results of C-CAR039 Between November 5, 2019, and January 11, 2022, 48 patients received C-CAR039 at the dose ranges of 1.0 x 106 to 5.0x106 CAR-T cells/kg. Of the 48 patients, 44 (91.7%) patients had large B-cell lymphoma (LBCL) (DLBCL, n=37; PMBCL, n=3; tFL, n=4), 3 patients had FL and 1 patient had MCL. The median age was 55 (range, 25-71) years, and 11 (22.9%) patients were ≥ 65 years. Thirty-six (75%) patients were in Ann Arbor Stage III/IV with 3 median prior lines of therapy, 32 (66.7%) patients were refractory to their last treatment, and 22 (45.8%) patients never achieved CR to their prior therapies. As of September 25, 2023, 45 patients (93.8%) experienced CRS, only 1 (2.1%) were grade 3. Three patients had grade 1 or 2 ICANS at a dose of 5.0x106 CAR-T cells/kg. Grade 3 or higher cytopenia not resolved by Day 30 following C-CAR039 infusion included neutropenia (54.2%), thrombocytopenia (20.8%), and anemia (20.8%). At cutoff date, 66.7% patients had infections with 25% grade 3 or higher. Second primary malignancy after C-CAR039 infusion was observed in 3 patients and none were related to C-CAR039. Fifteen deaths occurred, 11 due to disease progression. Of the 48 patients, 47 patients were evaluable for efficacy. The median follow-up time was 30.0 months. The ORR and CR rate among evaluable patients were 91.5% and 85.1% respectively. Of the 43 LBCL patients, the ORR was 90.7%, with 86.0% CR. Median duration of response (DOR) was not reached. 23/47 (48.9%) patients remain in CR, 10 of them for more than 36 months. Median PFS has not been reached. KM estimates of 24-m PFS rate were 62.6% (all patients) and 64.1% (LBCL). Median OS has not been reached. KM estimates of 24-m OS rate were 76.5% (all patients) and 79.0% (LBCL). The complete text of the abstract can be found About the C-CAR066 Study C-CAR066 is a novel second generation CAR-T therapy targeting the CD20 antigen. Preclinical studies suggest that C-CAR066 has superior anti-tumor activity compared to anti-CD20 CAR-Ts derived from scFVs of Leu16, Rituximab and Obinutuzumab, and to anti-CD19 CAR-Ts derived from scFV FMC63. The Phase I clinical trials (NCT04036019, NCT04316624) were conducted in Shanghai Tongji Hospital and Institute of Hematology & Blood Diseases Hospital in Tianjin, China, to evaluate the safety and efficacy of C-CAR066 in subjects with r/r B-NHL who were previously treated with and failed after an anti-CD19 CAR-T therapy. C-CAR066 was administered as a single intravenous dose after a 3-day cyclophosphamide (300mg/m2x3d) plus fludarabine (30mg/m2x3d) conditioning regimen. Key Results of C-CAR066 Between October 16, 2019, and August 17, 2021, a total of 14 patients received C-CAR066 at doses of 2.0x106 CAR-T cells/kg and 3.0x106 CAR-T cells/kg. Eleven patients (78.6%) were DLBCL, 3 patients (21.4%) were tFL. The median age was 54.5 years (range, 37-67). Twelve patients (85.7%) were in Ann Arbor Stage III/IV. The median number of prior lines of therapy was 5 (range, 2-7). All patients had prior CD19 CAR-T therapy. As of October 10, 2023, 12/14 patients (85.7%) experienced CRS, all were grade 1/2, except for 1 patient who experienced a grade 4 CRS. No patients experienced ICANS. Grade 3 or higher cytopenia not resolved by Day 30 following C-CAR066 infusion occurred in 28.6% patients and included neutropenia (21.4%), thrombocytopenia (14.3%), and anemia (14.3%). At cutoff date, 8 patients experienced infections, only 2 were grade 3. Seven deaths occurred and all due to disease progression. No SPM and new safety signals were observed with longer follow-up. The investigator assessed ORR was 92.9%, with 57.1% CR. With the median follow-up of 27.7 months, median PFS and DOR were 9.4 months and 8.3 months, respectively. Four patients had remained in CR for more than 30 months. The Kaplan-Meier estimate of median OS was 34.8 months (11.4 - NA).
