PURPOSEAnal cancer is increasing in HIV+ men who have sex with men (MSM). Treatment options for its precursor, high-grade anal intraepithelial neoplasia (HGAIN), are suboptimal. In this phase I to II dose-finding study, we assessed the safety and efficacy of the human papillomavirus type 16 (HPV16) synthetic long peptide vaccine (SLP-HPV-01) in HIV+ MSM with HPV16-positive HGAIN.PATIENTS AND METHODSFour dosage schedules (1-5-10; 5-10-20; 10-20-40; and 40-40-40-40 μg) of SLP-HPV-01 were administered intradermally with a 3-week interval in 10 patients per dose level (DL). In each dose group, 5 patients also received 1 μg/kg pegylated IFNα-2b subcutaneously. Primary endpoints were safety and regression of HGAIN at 3, 6, and 12 months.RESULTSEighty-one of 134 screened patients (60%) had HPV16-negative HGAIN lesions, leaving 53 eligible patients. Thirteen patients were excluded, leaving 40 men. The vaccine was well tolerated. One patient developed a generalized rash. The highest dosage level induced the strongest immune responses. There was no indication for stronger reactivity in the IFNα groups. Up to 18 months of follow-up, 8/38 intention-to-treat patients had a complete clinical and histologic response and one had a partial response (in total 9/38, 23.7%). At the highest dosage level, the clinical response was 4/10 (40%). Stronger immune responses were detected among clinical responders.CONCLUSIONSThe highest DL is safe, immunogenic, and associated with clinical responses to HPV16-induced lesions. However, as the majority of HGAIN is caused by the other HPV types, further studies should aim at pan-HPV vaccination to prevent or treat HGAIN.

Combination immunotherapy with synthetic long peptides and chemotherapy or PD-1 blocker for cancers caused by human papilloma virus type 16

Review

Author: Melief, Cornelis J M ; van der Gracht, Esmé ; Wiekmeijer, Anna-Sophia

Therapeutic vaccination of premalignant conditions and of different stages of cancer can be accomplished with several platforms including DNA vaccines, RNA vaccines, synthetic long peptides (SLP), and recombinant viruses. We successfully used a therapeutic vaccine composed of SLP covering the complete sequence of the two oncogenic proteins E6 and E7 of human papillomavirus type 16 (HPV16) as monotherapy in patients with premalignant disease. However, combination treatment might be required in patients with (advanced) cancer because of the hostile cancer microenvironment for T cells in established HPV16+ cancer, often associated with systemic immunosuppression. In patients with late-stage recurrent or metastatic HPV16+ cancers, we have therefore combined treatment with the SLP vaccine, called ISA101b, with either standard-of-care chemotherapy or with immune checkpoint inhibition with anti-PD-1 monoclonal antibody. A strong vaccine-induced interferon gamma-producing T cell response to HPV16 E6/E7 was associated with significantly better survival. In a second phase 1/2 study, patients with recurrent or metastatic HPV16+ oropharyngeal cancer were treated with the combination of ISA101b and anti-PD-1 (nivolumab). In this trial, the clinical overall response rate (ORR) in 22 patients was 36%, twice the ORR in the nivolumab registration trial for this category of patients, and 2/22 patients had a complete clinical response that is ongoing after 4 1/2 years. Other promising strategies for late-stage cancer recipients are the infusion of expanded tumor-infiltrating lymphocytes or the infusion of T cell receptor transduced T cells, both directed against HPV16.

BackgroundThe combination of ISA101, a human papilloma virus (HPV) 16 peptide vaccine, and nivolumab showed a promising response rate of 33% in patients with incurable HPV-16+cancer. Here we report long-term clinical outcomes and immune correlates of response.MethodsPatients with advanced HPV-16+cancer and less than two prior regimens for recurrence were enrolled to receive ISA101 (100 µg/peptide) on days 1, 22, and 50 and nivolumab 3 mg/kg every 2 weeks beginning day 8 for up to 1 year. Baseline tumor samples were stained with multiplex immunofluorescence for programmed death-ligand 1 (PD-L1), programmed cell death protein-1 (PD-1), CD3, CD8, CD68, and pan-cytokeratin in a single panel and scanned with the Vectra 3.0 multispectral microscope. Whole transcriptome analysis of baseline tumors was performed with Affymetrix Clariom D arrays. Differential gene expression analysis was performed on responders versus non-responders.ResultsTwenty-four patients were followed for a median of 46.5 months (95% CI, 46.0 months to not reached (NR)). The median duration of response was 11.2 months (95% CI, 8.51 months to NR); three out of eight (38%) patients with objective response were without progression at 3 years. The median and 3-year overall survival were 15.3 months (95% CI, 10.6 months to 27.2 months) and 12.5% (95% CI, 4.3% to 36%), respectively. The scores for activated T cells ((CD3+PD-1+)+(CD3+CD8+PD-1+)), activated cytotoxic T cells (CD3+CD8+PD-1+), and total macrophage ((CD68+PD-L1−)+(CD68+PD-L1+)) in tumor were directly correlated with clinical response (p<0.05) and depth of response with the two complete response patients having the highest degree of CD8+T cells. Gene expression analysis revealed differential regulation of 357 genes (≥1.25 fold) in non-responders versus responders (p<0.05). Higher expression of immune response, inflammatory response and interferon-signaling pathway genes were correlated with clinical response (p<0.05).ConclusionsEfficacy of ISA101 and nivolumab remains promising in long-term follow-up. Increased infiltration by PD-1+T cells and macrophages was predictive of response. Enrichment in gene sets associated with interferon-γ response and immune infiltration strongly predicted response to therapy. A randomized trial is ongoing to test this strategy and to further explore correlates of immune response with combined nivolumab and ISA101, versus nivolumab alone.Trial registration numberNCT02426892.

One shot of HPV vaccine protects long-term against cervical cancer

Women should be safe from cancer-causing human papilloma virus (HPV) for at least 20 years and probably more after just one dose of vaccine instead of the usual two or three, according to a study that further demonstrates the long-term effectiveness of a single dose. When first approved by the Food and Drug Administration nearly 20 years ago, vaccines against cancer-causing HPV were scheduled in three doses for adequate protection. But the cost and logistics of giving three shots, particularly in remote or underserved regions, can make it difficult to complete the full regimen. The new study pulled data from the ongoing Costa Rica HPV Vaccine Trial, which provided initial evidence that one dose of the bivalent HPV vaccine protected against HPV-16/18 infections. Researchers wanted to see how durable that protection was, because early on scientists observed that antibody responses from three vaccine doses were about four times higher than those from just one dose. So, they examined data from 500 of the Costa Rica trial participants. These included a group who had received three vaccine doses and a separate group aged 18 to 25 who got a single dose. All had agreed to follow-up visits 11, 14, and 16 years after vaccination.  The researchers gauged antibody levels against HPV-16 and HPV-18 at 11 and 16 years post-vaccination and reported in the Journal of the National Cancer Institute Monographs that antibody levels declined a bit over five years – with the three-dose levels declining faster. But HPV-16 and HPV-18 antibody seropositive rates from both dosing regimens "remained exceedingly high 16 years after vaccination." "Given the one-dose levels observed at 16 years, we project that women will have adequate antibody levels for much longer after vaccination with the bivalent HPV vaccine," the scientists reported. “Therefore, our study lends additional support to the World Health Organization recommendation of using a single-dose HPV vaccine schedule in immunization programs worldwide.” The current research was led by the Division of Cancer Epidemiology and Genetics, National Cancer Institute (NCI), with collaborators Ligia Pinto, Ph.D., and Troy Kemp, Ph.D., of the Frederick National Laboratory for Cancer Research where all antibody testing was done; Doug Lowy, M.D., of NCI; and scientists from both Agencia Costarricense de Investigaciones Biomédicas, in San José, Costa Rica, and Information Management Services in Maryland.

SCG Cell Therapy Presented New Preclinical Data in an Oral Presentation at ASGCT 2024 Annual Meeting Highlighting Superior Tumor Inhibition of its Immunoswitch Armored HPV-TCR T Cell Therapy (SCG142) against a Broad Range of HPV-associated Cancers

SINGAPORE, May 12, 2024 /PRNewswire/ -- SCG Cell Therapy Pte Ltd (SCG), a clinical-stage biotechnology company developing novel immunotherapies for infectious diseases and their associated cancers, announced first preclinical data of its novel human papillomavirus (HPV)-specific T cell receptor-engineered T (TCR T) cell therapy armored with an TGFβRII-41BB immunoswitch – SCG142 – in an oral presentation at the American Society of Gene & Cell Therapy (ASGCT) Annual Meeting in Baltimore, Maryland. In preclinical studies, SCG142 demonstrated superior CD8+ and CD4+ TCR T cell proliferation and tumor inhibition both in-vitro and in-vivo compared to conventional TCR T without immunoswitch, including tumor rechallenge models. Importantly, SCG142 functionality is CD8 co-receptor independent, transferring desired effector functions also to CD4+ T cells and promoting longer persistence and improved proliferation of T cells. In addition, SCG142 exhibited high functional avidity and can recognize both genotypes HPV-16 and HPV-52, with a favorable safety profile with no alloreactivity or off-target toxicity in relevant toxicology models. "SCG142 is a novel and differentiated HPV-specific TCR T cell therapy with preclinical efficacy in various tumor types with expression of HPV-16- and HPV-52 genotypes. We're excited to demonstrate that armoring the TCR-T cells with the chimeric switch receptor didn´t change the favorable safety profile but helped to overcome the immune inhibitory signal of TGF-β, which can be crucial for effective treatment of solid tumors", said Dr. Susanne Wilde, Head of Preclinical Research of SCG Cell Therapy. "These promising results underscore the potential of SCG142 to provide new solutions for patients in a variety of HPV-16- and HPV-52 expressing cancers. Based on these encouraging data, we are eagerly advancing SCG142 towards clinical trials", she added. About SCG142 SCG142, an autologous HPV-specific TCR T cell therapy holding the promise as the best-in-class product. Utilizing SCG's proprietary GianTCRTM technology, high affinity and high avidity natural TCRs can be isolated to target against intracellular antigens presented through major histocompatibility complex (MHC) in solid tumors. Study results showed that SCG142, a fully natural HPV specific TCR armoured with chimeric switch receptor, has the potential to specially target HPV-16 and HPV-52-positive tumor cells in various HPV-related tumor types, generating CD8 co-receptor independent T cell functionality and sustained anti-tur activity. About Human Papillomavirus and Cancers Human papillomavirus (HPV) infection is the most common sexually transmitted infection. Nearly all sexually active people are infected with HPV and around half of these infections occur with a high-risk HPV type, which can lead to cancer development.1 As such, HPV infection accounts for more than 90% of anal and cervical cancers, about 70% of vaginal and vulvar cancers, and 60% of penile and oropharyngeal cancers, and it causes an estimated 630,000 cancers worldwide each year2x. About SCG Cell Therapy SCG is a leading biotechnology company focusing on the development of novel immunotherapies in infections and its associated cancers. The company targets the most common cancer-causing infections: helicobacter pylori, HPV, HBV and EBV, and develops a broad and unique pipeline of TCR-based cellular immunotherapy products against infection- associated cancers.

Ultimovacs downsizes to funnel funds to cancer vaccine programme

Ultimovac’s UV1 works by inducing T cell response against telomerase reverse transcriptase (hTERT) – a protein that provides the limitless self-renewal hallmark in cancer progression. Image Credit: CI Photos / Shutterstock. Ultimovacs has implemented cash-saving strategies, including a 40% workforce reduction, to extend its reserves into Q4 2025. The operational adjustments are expected to provide a cash runway beyond the anticipated top-line readout from the next two Phase II trials – the FOCUS trial in Q3 this year, and the DOVACC trial in H1 2025. The UV1 cancer vaccine development programme has suffered some setbacks. The company has reported topline data from two Phase II trials, NIPU and INITIUM, for the vaccine used in combination with PD1 inhibitors in two cancer indications, with both trials failing to meet primary endpoints. The Phase II NIPU trial (NCT04300244) evaluated UV1 in combination with Bristol Myers Squibb’s checkpoint inhibitors Opdivo (nivolumab) and Yervoy (ipilimumab) as a second-line treatment in mesothelioma patients. The study failed to meet its primary endpoint of progression-free survival (PFS). The Phase II INITIUM trial (NCT02275416) also evaluated the UV1, Opdivo and Yervoy combination but in patients with unresectable or metastatic malignant melanoma. The study also failed to meet primary endpoints, with the company deciding to stop pursuing the therapy in this indication. See Also: NIH team develops AI tool to predict cancer drug response SGN-1 by Guangzhou Huajin Pharmaceutical Technology for Peritoneal Cancer: Likelihood of Approval Despite this, Ultimovacs expects positive readouts from the next two trials. The Phase II FOCUS trial (NCT05075122) evaluates the combination treatment of UV1 vaccine with MSD’s Keytruda (pembrolizumab) as a first-line treatment in patients with PD-L1 positive head and neck squamous cell carcinoma. The combination has been successful in the Phase I trial (NCT03538314), with an observed 67% overall survival rate at a three-year follow-up. While the company expects positive data in Q3 this year, it is prepared to wait for data readout from the DUVACC trial before deciding on the fate of UV1 should the FOCUS trial fail, said Ultimovac’s CEO Carlos de Sousa in a business update webcast today. The Phase II DUVACC trial (NCT04742075) evaluates UV1 in combination with AstraZeneca’s checkpoint inhibitor Infinzi (duvalumab) and Lynparza (olaparib), a poly-ADP ribose polymerase (PARP) inhibitor, as a second line treatment in patients with BRCA negative ovarian cancer. The trial is currently recruiting patients, with 40% of the total expected enrolment completed as of Q4 2023. UV1 is also being evaluated in an investigator-led Phase II LUNGVAC trial (NCT05344209). The study investigates the combination therapy of UV1 and Sanofi and Regeneron’s Libtayo (cemiplimab) as a first-line therapy in patients with advanced or metastatic non-small cell lung cancer. The trial started recruitment in October 2022 and reached only 15% enrolment as of Q4 2023. The topline data from the trial is expected in H1 2026. GlobalData forecasts therapeutic cancer vaccines as the weakest immuno-oncology agent class with relatively low global sales of up to $4bn by 2028, compared to checkpoint modulators sales reaching $120bn by 2028. GlobalData is the parent company of Pharmaceutical Technology . Other cancer vaccines in development include Transgene and Japanese NEC Corporation’s cancer vaccine, TG4050 , for the treatment of head and neck cancers and ISA Pharmaceuticals’ cancer vaccine, ISA101b , for treating oropharyngeal cancer.
