II ; Walter, Ashley

BACKGROUNDOutcomes of recurrent paediatric high-grade glioma are poor, with a median overall survival of less than 6 months. Viral immunotherapy, such as the polio-rhinovirus chimera lerapolturev, is a novel approach for treatment of recurrent paediatric high-grade glioma and has shown promise in adults with recurrent glioblastoma. The poliovirus receptor CD155 is ubiquitously expressed in malignant paediatric brain tumours and is a treatment target in paediatric high-grade glioma. We aimed to assess the safety of lerapolturev when administered as a single dose intracerebrally by convection enhanced delivery in children and young people with recurrent WHO grade 3 or grade 4 glioma, and to assess overall survival in these patients.METHODSThis phase 1b trial was done at the Duke University Medical Center (Durham, NC, USA). Patients aged 4-21 years with recurrent high-grade malignant glioma (anaplastic astrocytoma, glioblastoma, anaplastic oligoastrocytoma, anaplastic oligodendroglioma, or anaplastic pleomorphic xanthoastrocytoma) or anaplastic ependymoma, atypical teratoid rhabdoid tumour, or medulloblastoma with infusible disease were eligible for this study. A catheter was tunnelled beneath the scalp for a distance of at least 5 cm to aid in prevention of infection. The next day, lerapolturev at a dose of 5 × 10⁷ median tissue culture infectious dose in 3 mL infusate loaded in a syringe was administered via a pump at a rate of 0·5 mL per h as a one-time dose. The infusion time was approximately 6·5 h to compensate for volume of the tubing. The primary endpoint was the proportion of patients with unacceptable toxic effects during the 14-day period after lerapolturev treatment. The study is registered with ClinicalTrials.gov, NCT03043391.FINDINGSBetween Dec 5, 2017, and May 12, 2021, 12 patients (11 unique patients) were enrolled in the trial. Eight patients were treated with lerapolturev. The median patient age was 16·5 years (IQR 11·0-18·0), five (63%) of eight patients were male and three (38%) were female, and six (75%) of eight patients were White and two (25%) were Black or African American. The median number of previous chemotherapeutic regimens was 3·50 (IQR 1·25-5·00). Six of eight patients had 26 treatment-related adverse events attributable to lerapolturev. There were no irreversible (ie, persisted longer than 2 weeks) treatment-related grade 4 adverse events or deaths. Treatment-related grade 3 adverse events included headaches in two patients and seizure in one patient. Four patients received low-dose bevacizumab on-study for treatment-related peritumoural inflammation or oedema, diagnosed by both clinical symptoms plus fluid-attenuated inversion recovery MRI. The median overall survival was 4·1 months (95% CI 1·2-10·1). One patient remains alive after 22 months.INTERPRETATIONConvection enhanced delivery of lerapolturev is safe enough in the treatment of recurrent paediatric high-grade glioma to proceed to the next phase of trial.FUNDINGSolving Kids Cancer, B+ Foundation, Musella Foundation, and National Institutes of Health.

BackgroundWe previously reported results from a phase 1 study testing intratumoral recombinant poliovirus, lerapolturev, in 12 melanoma patients. All 12 patients received anti-PD-1 systemic therapy before lerapolturev, and 11 of these 12 patients also received anti-PD-1 after lerapolturev. In preclinical models lerapolturev induces intratumoral innate inflammation that engages antitumor T cells. In the current study, prelerapolturev and postlerapolturev tumor biopsies and blood were evaluated for biomarkers of response.MethodsThe following analyses were performed on tumor tissue (n=11): (1) flow cytometric assessment of immune cell density, (2) NanoString Digital Spatial profiling of protein and the transcriptome, and (3) bulk RNA sequencing. Immune cell phenotypes and responsiveness to in vitro stimulation, including in vitro lerapolturev challenge, were measured in peripheral blood (n=12).ResultsThree patients who received anti-PD-1 therapy within 30 days of lerapolturev have a current median progression-free survival (PFS) of 2.3 years and had higher CD8+T cell infiltrates in prelerapolturev tumor biopsies relative to that of 7 patients with median PFS of 1.6 months and lower CD8+T cell infiltrates in prelerapolturev tumor biopsies. In peripheral blood, four patients with PFS 2.3 years (including three that received anti-PD-1 therapy within 30 days before lerapolturev and had higher pretreatment tumor CD8+T cell infiltrates) had significantly higher effector memory (CD8+, CCR7-, CD45RA-) but lower CD8+PD-1+ and CD4+PD-1+ cells compared with eight patients with median PFS 1.6 months. In addition, pretreatment blood from the four patients with median PFS 2.3 years had more potent antiviral responses to in vitro lerapolturev challenge compared with eight patients with median PFS 1.6 months.ConclusionAn inflamed pretreatment tumor microenvironment, possibly induced by prior anti-PD-1 therapy and a proficient peripheral blood pretreatment innate immune response (antiviral/interferon signaling) to lerapolturev was associated with long term PFS after intratumoral lerapolturev in a small cohort of patients. These findings imply a link between intratumoral T cell inflammation and peripheral immune function.Trial registration numberNCT03712358.

Discover which therapies are expected to grab the major glioma market share @ Glioma Market Report Glioma Overview Glioma is the most common kind of glial cell tumor in the central nervous system (CNS). Gliomas are infiltrative tumors that affect the brain tissue surrounding them. Glioblastoma is the most hazardous type of brain tumor, whereas pilocytic astrocytomas are the least dangerous. Previously, diffuse gliomas were classified into subgroups and grades depending on histopathologies, such as diffuse astrocytomas, oligodendrogliomas, or mixed gliomas/oligoastrocytomas. The specific etiology of glioma, like other primary brain tumors, remains unknown. However, certain variables may increase the risk of getting a brain tumor. Glioma symptoms vary depending on tumor type, size, location, and growth rate. Some common glioma symptoms include headache, nausea or vomiting, memory loss, urine incontinence, speech problems, and others. A medical history and a physical examination are used for glioma diagnosis. Glioma Epidemiology Segmentation DelveInsight estimates that there were approximately 47K incident cases of glioma in the 7MM in 2022. As per our analysis, the United States contributed to the largest incident population of glioma, acquiring ~40% of the 7MM in 2022. The glioma market report proffers epidemiological analysis for the study period 2019–2032 in the 7MM segmented into: Total glioma incident cases Glioma grade-specific cases Glioma age-specific cases Glioma type-specific cases Download the report to understand which factors are driving glioma epidemiology trends @ Glioma Epidemiological Insights Glioma Treatment Market Glioma treatment is based on the type of glioma, its size and location, and the patient's unique characteristics. Chemotherapy and radiation therapy will be administered after surgery, particularly in individuals when the tumor cannot be removed entirely because it has invaded critical parts of the brain or is inaccessible. The typical glioma treatment protocol comprises surgery, chemotherapy, and radiation. Chemotherapy may include carmustine (BCNU), lomustine (CCNU), or gleostine (generic), cisplatin, carboplatin, etoposide, and irinotecan in case of low-grade glioma whereas temozolomide (TEMODAR) is the standard chemotherapy used in case of high-grade glioma majorly, Gliadel wafer implants (biodegradable discs injected with BCNU) are usually given as adjunctive treatment after surgery, although usage of Gliadel wafers remains a point of controversy due to its questionable survival benefits. Avastin (Genentech) and Temodar/Temodal (Merck), among others, are approved medications for HGG. However, due to patent expiration, the generic version of Temodar and biosimilars of Avastin are available on the glioma market. As generics and biosimilars are more cost-effective for patients than new medicines, intense competition exists among them. Furthermore, due to a lack of knowledge concerning bevacizumab's overall survival benefit, it is not recommended in unselected patients with newly diagnosed GBM. Currently, only one medication for LGG is approved, Tafinlar (dabrafenib) plus Mekinist (trametinib). Moreover, the current therapeutic market lacks a viable method for curing glioblastoma; therefore, the survival rate of people diagnosed with glioma remains poor. Glioma is incurable, and treatment choices are limited. Furthermore, the tumor has a high recurrence rate and a poor patient prognosis. In addition, there is currently no approved therapy for the unmethylated MGMT patient pool.

Commercially, there is a greater emphasis on high-grade glioma than low-grade glioma because patients with low-grade glioma often live longer than those with high-grade glioma. As a result, just a few therapies are in late-stage studies, while the majority are in early-stage trials. In the case of GBM, on the other hand, the pipeline is robust, with numerous potential therapies in late and mid-stage research that have yet to be marketed. The pipeline includes drugs with varied modes of action and administration routes. It is interesting to note that the emerging market of glioma includes budding gene therapy, i.e., ofranergene obadenovec (VB-111) by VBL Therapeutics, followed by four vaccine/immunotherapy candidates such as VBI-1901, AV-GBM-1 and ITI-1000 (pp65 DC Vaccine), tasadenoturev (DNX-2401) by VBI Vaccines, Aivita Biomedical, Immunomic Therapeutics, and DNAtrix, respectively, and these therapies are going to alter the glioma market dynamics in the upcoming years. The current glioma market has been categorized based on the dominant treatment pattern across the 7MM, which shows slight variances in the overall prescription pattern. The forecast model considers surgery, chemotherapy/radiation therapy, bevacizumab + radiotherapy/chemotherapy, and OPTUNE with temozolomide. The anticipated launch of new therapies and improved integration of early patient screening, medication in secondary care and other clinical settings, research on optimum implementation methods, and increased awareness may eventually facilitate the development of successful treatment alternatives. However, there are a few challenges to the timely identification and treatment of these patients, such as a lack of a reliable biomarker that can aid in diagnosis and patient classification and identifying recurrence and signaling medication response. Furthermore, the failure rate of high-phased drug trials is significant, making it impossible to predict trial success, exacerbating the need for medicines that could assist ease the patient segment with this severe kind of cancer.

Istari Oncology Announces First Patient Dosed in the Non-Muscle-Invasive Bladder Cancer (NMIBC) Substudy of the LUMINOS-103 Basket Trial Evaluating Lerapolturev Monotherapy

DURHAM, N.C.--(BUSINESS WIRE)--Istari Oncology, Inc., a clinical-stage biotechnology company focused on development of the novel immune activator lerapolturev for the treatment of solid tumors, today announced the first patient has been dosed via intravesicular instillation in the non-muscle-invasive bladder cancer (NMIBC) cohort of the LUMINOS-103 basket trial. LUMINOS-103 is a dynamic phase 1/2 open-label basket trial evaluating the administration of lerapolturev with or without PD-1/L1 inhibitors in adult subjects with solid cancers. “We know that NMIBC tissue expresses the poliovirus receptor, CD155 and is responsive to immunotherapy, providing the rationale for intravesicular lerapolturev for patients with low to intermediate risk BCG-naïve NMIBC,” said W. Garrett Nichols, MD, MS, Chief Medical Officer at Istari Oncology. “Approximately 60,000 patients with low to intermediate risk NIMBC are identified each year in the US alone; these patients could benefit from a well-tolerated immunotherapy such as lerapolturev as a replacement for repeat resections and intravesicular chemotherapy.” This substudy is designed to test the intravesical instillation of lerapolturev and its ability to infect tumor cells and infiltrating APCs within tumor tissue lining the bladder mucosa. To facilitate efficient enrollment, a heterogenous population of patients is being recruited (prior history of stage Ta, T1, or Tis urothelial carcinoma of the bladder; recurrent disease requiring TURBT or cystectomy). If successful, the planned patient population for phase 2 will be patients with low- to intermediate-risk BCG-naïve disease. “We’re pleased to be the exclusive site for the NMIBC sub-study,” said Dr. Neal Shore principal investigator and Director, Carolina Urologic Research Center. “This is a largely unaddressed population of NMIBC patients that, if we can identify and intervene early and effectively with a therapy like lerapolturev, can avoid progression and repeated surgeries or treatment with BCG, which has experienced severe shortages.” Recruiting for the NMIBC substudy is ongoing and is expected to reach full enrollment by mid-year.

About Lerapolturev Lerapolturev is an investigational immunotherapy based on the live attenuated Sabin type 1 polio vaccine genetically modified for safety. Lerapolturev has a distinct target (the poliovirus receptor CD155), which is widely expressed in neoplastic cells of most solid tumors. Via CD155, Lerapolturev targets tumors with three key mechanisms: 1) engagement and activation of antigen presenting cells (APCs), leading to T cell priming and sustained, systemic anticancer immunity; 2) direct tumor cell killing and antigen release; and 3) amplification of the immune response via recall of polio vaccine-specific T cells. Lerapolturev has been granted Breakthrough Therapy and Orphan Drug Designation status by the U.S. Food and Drug Administration in recurrent glioblastoma, and Fast Track and Orphan Drug Designation status in refractory melanoma. About Istari Oncology Istari Oncology, Inc., headquartered in Research Triangle Park, North Carolina, is a privately held clinical-stage biotechnology company focused on development of the novel immune activator lerapolturev for the treatment of solid tumors. Istari has licensed a broad range of patents and patent applications and has access to additional intellectual property to continue clinical and commercial development of lerapolturev.

Istari Oncology Announces Presentation of Clinical Responses from LUMINOS- 102, an ongoing Phase 2 Trial of Lerapolturev in anti-PD-1 Refractory Metastatic Melanoma at the Society for Melanoma Research (SMR) 2022 Congress

Among subjects receiving an enhanced dosing regimen of lerapolturev, a complete response and clinical benefit rate (CBR) of 71% has been observed Anti-tumor responses seen in both injected and non-injected lesions (e.g., abscopal response) including complete resolution of a non-injected lung metastasis Istari will continue enrolling patients to the enhanced dosing regimen with confirmatory data expected in Q2 2023 DURHAM, N.C.--(BUSINESS WIRE)-- Istari Oncology, Inc., a clinical-stage biotechnology company focused on development of the novel immune activator lerapolturev for the treatment of solid tumors, today announced a poster presentation of new data from an enhanced dosing cohort within the LUMINOS-102 phase 2 clinical trial, which is assessing the safety and efficacy of lerapolturev (formerly PVSRIPO) alone or in combination with a programmed death receptor-1 (PD-1) inhibitor in patients with metastatic melanoma who have progressed on an anti-PD-1 containing regimen, and BRAF/MEK inhibitors if BRAF mutation positive. The presentation is being made at the Society for Melanoma Research (SMR) Congress being held in Edinburgh October 17 - 20, 2022. Lerapolturev is a novel viral immunotherapy that activates the innate and adaptive immune system to produce a functional, systemic anticancer CD8+ T cell response. Following positive phase 1 monotherapy results,1 the LUMINOS-102 phase 2 multicenter trial (NCT04577807) was initiated to further explore lerapolturev’s impact on this tough-to-treat population of anti-PD-1 relapsed/refractory metastatic melanoma patients. “LUMINOS-102 initially used the lerapolturev dose that yielded a 67% (4/6) response rate in the phase 1 single-center trial,” said Garrett Nichols, MD, MS, Chief Medical Officer at Istari Oncology. “Following DSMB review and protocol amendment, a new dosing regimen was implemented for LUMINOS-102 in March 2022. Our poster presentation at SMR highlights the exciting responses we’ve seen among subjects treated with the new regimen. We are optimistic that we’ve now optimized the dosing regimen and are continuing to enroll subjects at this dose to confirm these encouraging results.” The dosing regimen now in place comprises a higher dose of lerapolturev with or without an “induction schedule” of weekly injections for seven weeks, followed by maintenance injections dictated by the cadence of anti-PD-1 infusions (every 2 or 3 weeks). Since implementation, seven (7) patients have been treated with the higher lera dose, with 3 subjects (those who were consented from the start of treatment under the protocol amendment) also receiving the induction dosing schedule. Among these patients, a clinical benefit rate (CR, PR or SD > 6 months) of 71% (5/7) has been observed, including a pathologic complete response (pCR). All subjects were heavily pretreated and had previously failed at least one anti-PD-1 therapy. Some participants had also failed anti-CTLA-4 and BRAF/MEK therapies. “We are pleased to see lerapolturev treatment yield responses, including responses in non- injected lesions”, remarked Yana G. Najjar, MD Assistant Professor of Medicine and Director, Clinical and Translational Center at the UPMC Hillman Cancer Center and Principal Investigator for LUMINOS-102. “Metastatic melanoma patients with anti-PD-1 relapsed/refractory disease have limited options and we’ve recently seen multiple investigational therapies fail in this setting. We’re hopeful that the responses seen with the new lera dosing strategy will be validated with additional patients and lead to further development”. LUMINOS-102 remains open to enrollment, with updates to be presented at an oncology congress in 2023. If successful, Istari plans to leverage its Orphan and Fast Track status in unresectable anti-PD-1 refractory melanoma by collaborating with regulators on a registration strategy.

While immune checkpoint inhibitors have dramatically improved the outlook for advanced melanoma patients today, most patients treated with these immunotherapies are either primary nonresponders or eventually develop immune-refractory progressive disease and require additional options, which are poor. About Istari Oncology Istari Oncology, Inc., headquartered in Research Triangle Park, North Carolina, is a privately held clinical-stage biotechnology company focused on development of the novel immune activator lerapolturev for the treatment of solid tumors. Istari has licensed a broad range of patents and patent applications and has access to additional intellectual property to continue clinical and commercial development of lerapolturev.
