A Phase I/II Trial of SCIB1, a DNA Immunotherapy, in the Treatment of Patients With Malignant Melanoma

The study is an investigation of a novel immunotherapy, SCIB1, for the treatment of melanoma. SCIB1 is a solution of plasmid DNA molecules which will express a modified antibody in human cells. The antibody modifications are designed to stimulate the patient's immune T cells to have a strong and specific reaction against melanoma cells which should then be eliminated. SCIB1 is injected into muscle using a device which simultaneously delivers an electrical impulse to enhance the transfer of SCIB1 into muscle cells. The trial will assess the safety and tolerability of SCIB1, the safety and performance of the injection device and the immunological effects of SCIB1. This is the first study of SCIB1 in humans and the trial has two parts, in the first part the dose will be escalated to determine a safe and tolerable level up to a maximum of 8 mg per dose. In the second part patients will receive the dose determined in the first part. Patients will have stage III or IV melanoma, be HLA type A2 and have a life expectancy of at least three months. All patients will receive 5 injections of SCIB1 over 5.5 months. At the discretion of the investigator, patients may continue to receive SCIB1 at 3-6 month intervals for 5 years. The study will be conducted at major cancer centres in the UK only and is expected to last for seven years. Patients will be followed up for five years after they have completed the trial.

A DNA vaccine, SCIB1, incorporating two CD8 and two CD4 epitopes from TRP-2/gp100 was evaluated in patients with metastatic melanoma. Each patient received SCIB1 via intramuscular injection with electroporation. The trial was designed to find the safest dose of SCIB1 which induced immune/clinical responses in patients with or without tumour. Fifteen patients with tumor received SCIB1 doses of 0.4-8 mg whilst 20 fully-resected patients received 2-8 mg doses. Twelve patients elected to continue immunization every 3 months for up to 39 months. SCIB1 induced dose-dependent T cell responses in 88% of patients with no serious adverse effects or dose limiting toxicities. The intensity of the T cell responses was significantly higher in patients receiving 4 mg doses without tumor when compared to those with tumor (p < 0.01). In contrast, patients with tumor showed a significantly higher response to the 8 mg dose than the 4 mg dose (p < 0.03) but there was no significant difference in the patients without tumor. One of 15 patients with measurable disease showed an objective tumor response and 7/15 showed stable disease. 5/20 fully-resected patients have experienced disease recurrence but all remained alive at the cut-off date with a median observation time of 37 months. A positive clinical outcome was associated with MHC-I and MHC-II expression on tumors prior to therapy (p = 0.027). We conclude that SCIB1 is well tolerated and stimulates potent T cell responses in melanoma patients. It deserves further evaluation as a single agent adjuvant therapy or in combination with checkpoint inhibitors in advanced disease.

SCIB1, a huIgG1 antibody DNA vaccination, combined with PD-1 blockade induced efficient therapy of poorly immunogenic tumors

Article

作者: Cook, Katherine W. ; Xue, Wei ; Yagita, Hideo ; Metheringham, Rachael L. ; Durrant, Lindy G. ; Symonds, Peter ; Brentville, Victoria A.

PURPOSE:

We have previously shown that supraoptimal signaling of high avidity T cells leads to high expression of PD-1 and inhibition of proliferation. This study was designed to see if this effect could be mitigated by combining a vaccine that stimulates high avidity T cells with PD-1 blockade.

EXPERIMENTAL DESIGN:

We investigated the anti-tumor effect of a huIgG1 antibody DNA vaccine (SCIB1) and PD-1 blockade.

RESULTS:

Vaccination of HLA-DR4 transgenic mice with SCIB1 induced high frequency and avidity T cell responses that resulted in survival (40%) of mice with established B16F1-DR4 tumors. SCIB1 vaccination was associated with increased infiltration of CD4 and CD8 T cells within the tumor but was also associated with upregulation of PD-L1 within the tumor environment. PD-1 blockade also resulted in increased CD8 T cell infiltration and an anti-tumor response with 50% of mice showing long term survival. In line with our hypothesis that PD-1/PD-L1 signaling results in inhibition of proliferation of high avidity T cells at the tumor site, the combination of PD-1 blockade with vaccination, enhanced the number and proliferation of the CD8 tumor infiltrate. This resulted in a potent anti-tumor response with 80% survival of the mice.

CONCLUSIONS:

There is a benefit in combining PD-1 blockade with vaccines that induce high avidity T cell responses and in particular with SCIB1.

TRP-2 / gp100 DNA vaccine and PD-1 checkpoint blockade combination for the treatment of intracranial tumors

Article

Abstract:

Intracranial tumors present a significant therapeutic challenge due to their physiological location. Immunotherapy presents an attractive method for targeting these intracranial tumors due to relatively low toxicity and tumor specificity. Here we show that SCIB1, a TRP-2 and gp100 directed ImmunoBody® DNA vaccine, generates a strong TRP-2 specific immune response, as demonstrated by the high number of TRP2-specific IFNγ spots produced and the detection of a significant number of pentamer positive T cells in the spleen of vaccinated mice. Furthermore, vaccine-induced T cells were able to recognize and kill B16HHDII/DR1 cells after a short in vitro culture. Having found that glioblastoma multiforme (GBM) expresses significant levels of PD-L1 and IDO1, with PD-L1 correlating with poorer survival in patients with the mesenchymal subtype of GBM, we decided to combine SCIB1 ImmunoBody® with PD-1 immune checkpoint blockade to treat mice harboring intracranial tumors expressing TRP-2 and gp100. Time-to-death was significantly prolonged, and this correlated with increased CD4+ and CD8+ T cell infiltration in the tissue microenvironment (TME). However, in addition to PD-L1 and IDO, the GBM TME was found to contain a significant number of immunoregulatory T (Treg) cell-associated transcripts, and the presence of such cells is likely to significantly affect clinical outcome unless also tackled.

Scancell picks winner from phase 2 cancer vaccine face-off, choosing next-gen prospect for pivotal trial

Scancell is now planning to take iSCIB1+ into a phase 2b/3 trial in patients with unresectable melanoma.\n Scancell has linked iSCIB1+ to a 69% response rate in advanced melanoma, leading the British biotech to advance the next-generation cancer vaccine candidate rather than its older sibling.The phase 2 study enrolled patients with advanced melanoma to receive either SCIB1 or iSCIB1+ on top of Bristol Myers Squibb’s aging checkpoint inhibitors Opdivo and Yervoy. Both Scancell candidates are designed to turn the immune system against tumors. The biotech modified SCIB1 to create iSCIB1+, resulting in a candidate intended to work in a wider range of melanoma patients. Tuesday, Scancell reported that the vaccines showed similar safety and efficacy in a phase 2 trial. The overall response rates in the first-line SCIB1 and iSCIB1+ cohorts were 68.4% and 68.9%, respectively. With little to choose between the candidates, Scancell picked iSCIB1+ for further development because it is suitable for use in about 80% of patients compared to just 35% to 40% for SCIB1.The biotech pooled data on SCIB1 and iSCIB1+ for a cross-trial comparison with BMS’ CheckMate-067 study. After 22 months, the rate of progression-free survival (PFS) in the pooled vaccine analysis was 69%. The result is a more than 20 percentage point improvement on the historical control, Scancell said. Further updates from the phase 2 trial are scheduled for later this year. Scancell plans to publish PFS and early overall survival data in the fourth quarter. Data from a cohort of patients who received iSCIB1+ on an accelerated dosing schedule are due by the end of the year. Scancell is now planning to take iSCIB1+ into a phase 2b/3 trial in patients with unresectable melanoma, although the study start is dependent on the biotech inking a deal or securing financing. The company is also assessing the potential to run a second study in patients with resectable tumors and, beyond that, sees a potential opportunity to establish iSCIB1+ as a preventive vaccine in at-risk groups.
