FasTCAR-19
FasTCAR-19 or GC007F uses Gracell’s patented FasTCARTM solution, which genetically modifies a patient’s T-cells to express CD19-specific chimeric antigen receptor (CAR) for the treatment of B-cell acute lymphoblastic leukemia (B-ALL).

Utilizing the unique bioprocessing, FasTCAR-19 cells can be produced overnight through viral transfection in use of Gracell’s proprietary fully-closed manufacturing system (from apheresis to filling). These cells are considered far more potent and durable in comparison to current market alternatives. To date, all 37 patient samples have been successfully manufactured. The process has been proven efficient, stable and duplicable, with a median 36.8% (range 13.1%-70.3%) transfection success and a median copies of 0.95 (range 0.2-4.21).

As of November, this investigational study enrolled 37 adult and adolescent patients aged from 14 to 70 years, who suffered from r/r B-ALL and had failed to respond to multiple prior lines of therapy, from eight clinical centers. All patients received a single infusion of FasTCAR-19 at one of the three-dose level (low: 0.6*10^5/kg; mid: 1.0*10^5/kg, and high: 1.6*10^5/kg), followed by prior conditioning regimen of fludarabine-cyclophosphamide (FC).

The treatment efficacy was assessed in 35 patients over 28 days of follow-up, of which:

34 (97.1%) achieved a complete remission with or without complete blood count recovery (CR/CRi) on Day 28;
32 (91.4%) achieved minimum residual disease negative complete remission (MRD-CR);
During the over six month-durable remission period, FasTCAR-19 demonstrated a good level of persistence in line with previous clinical trials. In terms of safety, all 37 patients tolerated the single infusion of FasTCAR-19 at different dose levels, with no dose-limiting toxicities observed. The most common safety concerns were cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS) where mild to moderate side effects were observed. Across 30 patients in the low to mid doses group, only 5 (16.7%) manageable Grade 3 CRS and 5 (16.7%) manageable Grade 3 ICANS were reported; while the remaining 23 (76.7%) had Grade 1-2 CRS. The low to mid doses group will likely be selected for extensive study in future clinical trials.

Beyond single-antigen CAR, Dual CAR-T cells can deliver promising clinical outcomes
Single-antigen CAR-T cells have demonstrated considerable efficacy; however, antigen loss and high relapse rate have been observed in a significant number of patients. To combat this, treatments containing two separate CARs and dual transduction (GC022 targeting CD19 and CD22, GC012 targeting BCMA and CD19) were developed. Following positive results from in vitro and in vivo studies, human clinical trials have commenced testing the safety and feasibility of Dual CAR-19-22 and Dual CAR-BCMA-19 to treat B-ALL and MM, respectively.

Dual CAR-19-22
Dual CAR-19-22 or GC022 has achieved a manufacturing success rate of 20/20, without any patient loss due to manufacturing failure. Enrolled patients aged from 4-45 years old who has B-ALL, received a single infusion of Dual CAR-19-22 at one of the three-dose levels (low: 0.5*10^6/kg; mid: 2.0*10^6/kg, and high: 3.0*10^6/kg), under conventional bioprocessing. The study demonstrated a very good safety profile and high efficacy at mid to high doses.

The treatment efficacy was assessed in 20 patients with a 28-day follow-up, of which:

4 in the low dose group reported no response;
15 of 16 (93.8%) in mid and high dose groups achieved complete remission, and confirmed with MRD-CR, with or without complete blood count recovery (CR/CRi) on Day 28.
Dual CAR-19-22 proved effective on patients who had previously been treated with CD19 CAR-T cells and/or received allogeneic hematopoietic stem cell transplantation (allo-HSCT) for r/r B-ALL but failed to benefit from prior treatments. Among these five patients, four (80%) patients achieved MRD-CR with a 28-day follow-up. Surpassing the 3-month durable remission period, fifteen patients still retain ongoing response.

Furthermore, Dual CAR-19-22 demonstrated an excellent safety profile, with 6/20 (30%) patients indicating no CRS, 14/20 (70%) reporting Grade 1 CRS. No ICANS events were reported.

Dual CAR-BCMA-19
Dual CAR-BCMA-19 or GC012 has been demonstrated effective in eliminating multiple myeloma (MM) tumor cells both in vitro and in vivo. The first-in-human study showed a good safety profile and effectiveness. Beyond, FasTCARTM has successfully been applied to Dual CAR-BCMA-19, expected to enhance proliferation, potency, and migration in the human body.

"We are delighted to see that patients with relapsed/refractory B-ALL continue to gain substantial clinical benefit from FasTCAR-19. Furthermore, Dual CAR-19-22 with conventional bioprocess can generate promising clinical data. This marks our confidence to utilize FasTCAR technology to both Dual CAR programs for various indications," said Dr. William Cao, CEO of Gracell. "The results from our latest clinical trials reveal the immense potential of FasTCAR technology, and we are eager to see Gracell’s highly efficacious, yet affordable therapies benefit more patients in China and worldwide."

About B-ALL
Acute lymphoblastic leukemia (ALL), although rare, is one of the most common forms of cancer in children between the ages of two and five and adults over the age of 501. In 2015, ALL affected around 837,000 people globally and resulted in 110,000 deaths worldwide2. It is also the most common cause of cancer and death from cancer among children. ALL is typically treated initially with chemotherapy aimed at bringing about remission. This is then followed by further chemotherapy carried out over several years.

About MM
Multiple myeloma (MM) is a cancer that forms in a type of white blood cell known as a plasma cell. MM cells are abnormal plasma cells (a type of white blood cell) that build up in the bone marrow and form tumors in many bones of the body. Healthy plasma cells make antibodies to help the body fight infection and disease. As the number of MM cells increases, more antibodies are produced. This can cause the blood to thicken and keep the bone marrow from making enough healthy blood cells. MM cells can also damage and weaken the bone. In 2018, MM affected around 160,000 people globally and resulted in 106,000 deaths worldwide3. Different types of treatments are available for patients with plasma cell neoplasms. Chemotherapy and targeted therapy are typical treatments; while stem cell transplant, biologic therapy, and radiation therapy, even surgery are also adopted.

On December 9, 2019 CStone Pharmaceuticals ("CStone" or the "Company", HKEX: 2616) reported that results from the CS1001-201 trial in a poster presentation at the 2019 American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting (Press release, CStone Pharmaceauticals, DEC 9, 2019, View Source [SID1234552151]).

CS1001-201 trial is a single-arm, multicenter Phase II clinical study designed to evaluate CS1001 monotherapy in relapsed or refractory extranodal natural killer (NK)/T-cell lymphoma (rr-ENKTL).

ENKTL is a subtype of mature T cell and NK cell lymphoma. It has a higher incidence in Asia than in Europe or North America. ENKTL is characterized by its rapid progression and poor prognosis. Currently, patients with rr-ENKTL lack effective treatment after failing an L-asparaginase-based combination chemotherapy regimen and targeted monotherapy only produces a complete response (CR) rate of below 10%.

"ENKTL accounts for approximately 6% of all lymphoma incidences, and there are vast unmet medical needs in this patient population that has failed the first-line treatment," said Dr. Frank Jiang, Chief Executive Officer and Chairman of CStone. "The CS1001-201 trial is the first clinical study of an anti-PD-L1 antibody in ENKTL worldwide. Our latest data have shown CS1001 to be well-tolerated with preliminary antitumor efficacy and survival benefit in rr-ENKTL patients. We will continue to advance this development program and hope that CS1001 will soon become a new treatment option for rr-ENKTL patients."

"CR is a critical outcome measure for the treatment of ENKTL. Studies have shown that ENKTL patients who achieved CR prior to autologous transplantations have a significantly better prognosis and longer survival than those who achieved partial response," said Dr. Jason Yang, Chief Medical Officer of CStone. "These latest results of CS1001 demonstrated a CR rate of 33.3% with durable response, an objective response rate of 43.3%, and a 1-year overall survival rate of 72.4%. These results represent a major breakthrough compared to current treatment options and support CS1001 as a potential conditioning regimen for hematopoietic stem cell transplantations."

Overview of the CS1001-201 trial

CS1001-201 is a single-arm, multicenter Phase II clinical study designed to evaluate CS1001 monotherapy in relapsed or refractory extranodal natural killer (NK)/T-cell lymphoma (rr-ENKTL).

The primary endpoint of the trial is ORR assessed by an independent radiological review committee (IRRC);
Secondary endpoints include investigator-assessed ORR; IRRC-assessed CR and PR rates, time to response, duration of response, progression-free survival; overall survival, and safety.
Results reported in the poster at the 2019 ASH (Free ASH Whitepaper) Annual Meeting

As of October 8, 2019, 32 patients were enrolled in the study. Among them, 24 patients (75.0%) had Stage IV ENKTL at screening, 9 patients (28.1%) received 2 lines of prior treatments, and 7 patients (21.9%) received 3 or more lines of prior treatments. All patients received 1200 mg CS1001 intravenously every 3 weeks for up to 2 years, until disease progression, intolerance, etc. The median duration of follow-up was 6.54 months (range, 0.72-15.64).

13 (40.6%) of the 32 enrolled patients remained on treatment, and 19 (59.4%) had discontinued from the study treatment.
Reasons for discontinuations included radiographic disease progression (12 patients), adverse events (AEs, 4 patients), and non-radiographic symptomatic progression (3 patients).
No deaths due to treatment-related AEs (TRAEs).
Preliminary efficacy data

CS1001 demonstrated promising antitumor activity and a favorable CR rate with durable response and survival benefit in rr-ENKTL patients.

Among the 30 efficacy-evaluable patients, the investigator-assessed ORR was 43.3%.
10 patients (33.3%) achieved CR and were still in remission.
3 patients (10.0%) achieved partial response (PR), and 1 additional patient achieved PR after pseudo-progression. The median duration of response (DoR) was not reached, and the maximum DoR was 10.9+ months.
The 1-year overall survival (OS) was 72.4% (95% CI: 52.0%-85.2%).
The IRRC assessments were not available at the time of data cut-off.
Safety data

CS1001 was well tolerated in patients with rr-ENKTL

The median duration of treatment was 12.6 weeks (range, 3.0-69.1).
30 patients (93.8%) reported treatment-emergent AEs (TEAEs).
24 patients (75.0%) reported TRAEs, of which 3 (9.4%) had Grade >3 TRAEs.
Grade 5 AEs were reported in 3 patients (9.4%), and none was assessed as related to CS1001.
7 patients (21.9%) reported serious AEs (SAEs). 1 case of Grade 4 sinus node dysfunction and 1 case of Grade 1 myositis were assessed as related to CS1001 by the investigator. Both patients later recovered from the SAEs.
Immune-related AEs (irAEs) were reported in 5 patients (15.6%). Except for 1 Grade 3 rash, all irAEs were Grade 1 in severity.
TEAEs that led to permanent treatment discontinuation occurred in 4 patients (12.5%).
No deaths due to AEs were assessed as related to CS1001.
About CS1001

CS1001 is an investigational monoclonal antibody directed against PD-L1 being developed by CStone. Authorized by the U.S. based Ligand Corporation, CS1001 is developed by the OMT transgenic animal platform, which can generate fully human antibodies in one step. As a fully human, full-length anti-PD-L1 monoclonal antibody, CS1001 is similar to natural G-type immune globulin 4 (IgG4) human antibody, which can reduce the risk of immunogenicity and potential toxicities, potentially representing a unique advantage over similar drugs.

CS1001 has completed a Phase I dose-escalation study in China, in which CS1001 showed good tolerability and produced sustained clinical benefits during the Phase Ia study.

CS1001 is being investigated in a number of ongoing clinical trials, including one Phase I bridging study in the U.S. In China, its clinical program includes one multi-arm Phase Ib study, two pivotal Phase II studies, and three Phase III studies for several tumor types.

On December 9, 2019 Amphivena Therapeutics, Inc., a private clinical stage immuno-oncology company developing T cell engager therapeutics for cancer, reported at the American Society of Hematology (ASH) (Free ASH Whitepaper) annual meeting data from a Phase 1 study of its bivalent T cell engager clinical candidate, AMV564 (Press release, Amphivena Therapeutics, DEC 9, 2019, View Source [SID1234552150]). In an oral presentation, Dr. Jorge E. Cortes, of the Georgia Cancer Center, Augusta University, Augusta, Georgia, said that the data provide early evidence of safety and clinical activity with evidence of T cell activation, increases in bone marrow T cells, and anti-leukemic blast activity. Of the 38 patients for whom response data was reported, five had Complete or Partial Responses as defined by the European LeukemiaNet (ELN) criteria.

"AMV564 was shown to be safe and well-tolerated, with no dose-limiting toxicities and no Grade 3+ Cytokine Release Syndrome (CRS), at doses up to 450 mcg/day in heavily pre-treated relapsed/refractory AML patients when administered by continuous IV infusion with a 14-day dosing regimen," said Dr. Cortes. "These findings provide a differentiated product profile that we believe should be further advanced in clinical development."

"We are pleased with the early signs of efficacy and safety in this First in Human clinical trial, and we are exploring subcutaneous and chronic dosing of AMV564 in other clinical trials," said Curtis Ruegg, Ph.D., President and CEO of Amphivena. "AMV564’s excellent safety profile supports conduct of combination trials of AMV564 with other agents as we look ahead into the AMV564 development program."

As of the data cutoff, 41 patients had been dosed with AMV564 and 11 dose cohorts were explored in a 14-day continuous IV dosing regimen. The primary objectives of the Phase 1 dose escalation study are to characterize the safety of AMV564 as well as identify a maximum tolerated dose and a recommended Phase 2 dose.

The presentation was made at 5:45 PM EST in the Chapin Theater (W320), Orange County Convention Center, Orlando, FL.

About AMV564

AMV564 is a bivalent, bispecific (2:2) T cell engager that binds CD33 and CD3. To date, over 50 patients have received AMV564 in two Phase 1 clinical trials for acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS). It is currently being evaluated in a First-in-Human Phase 1 trial in patients with relapsed/refractory AML at Washington University School of Medicine, MD Anderson Cancer Center, New York-Presbyterian/Weill Cornell Medical Center and Weill Cornell Medicine, Fred Hutchinson Cancer Research Center, The Ohio State University Wexner Medical Center, University of Pennsylvania Medical Center, Northwestern Memorial Hospital, and The Johns Hopkins Hospital.

The safety, efficacy and selectivity of AMV564 was highlighted most recently at the Society for Immunotherapy in Cancer (SITC) (Free SITC Whitepaper) Annual Meeting on November 7 where it was reported that AMV564 selectively reduces MDSC in the bone marrow and periphery in acute myeloid leukemia and myelodysplastic syndrome patients. The company also observed at SITC (Free SITC Whitepaper) that T cell activation on therapy can lead to rapid increases in MDSC that can be modulated by AMV564 due to avid binding of activated CD33 on MDSC. Amphivena also presented data at the 24th European Hematology Association (EHA) (Free EHA Whitepaper) meeting in Amsterdam (Abstract S877). Amphivena believes that AMV564 has demonstrated novel clinical activity by rapidly and selectively eliminating leukemic blasts and rare immature, granulocytic and monocytic MDSCs while sparing normal CD33-expressing cells, including neutrophils and monocytes.
