Oncolytic virotherapy may be a means of improving the dismal prognosis of malignant brain tumors. The rat H-1 parvovirus (H-1PV) suppresses tumors in preclinical glioma models, through both direct oncolysis and stimulation of anticancer immune responses. This was the basis of ParvOryx01, the first phase I/IIa clinical trial of an oncolytic parvovirus in recurrent glioblastoma patients. H-1PV (escalating dose) was administered via intratumoral or intravenous injection. Tumors were resected 9 days after treatment, and virus was re-administered around the resection cavity. Primary endpoints were safety and tolerability, virus distribution, and maximum tolerated dose (MTD). Progression-free and overall survival and levels of viral and immunological markers in the tumor and peripheral blood were also investigated. H-1PV treatment was safe and well tolerated, and no MTD was reached. The virus could cross the blood-brain/tumor barrier and spread widely through the tumor. It showed favorable pharmacokinetics, induced antibody formation in a dose-dependent manner, and triggered specific T cell responses. Markers of virus replication, microglia/macrophage activation, and cytotoxic T cell infiltration were detected in infected tumors, suggesting that H-1PV may trigger an immunogenic stimulus. Median survival was extended in comparison with recent meta-analyses. Altogether, ParvOryx01 results provide an impetus for further H-1PV clinical development.

The ParvOryx01 study was the first clinical study on oncolytic parvoviruses and the first clinical study in Germany to explore virotherapy.

Randomized, open-label phase IIb clinical trial that investigated Pexa-Vec plus best supportive care versus best supportive care in HCC patients who failed sorafenib therapy. Pexa-Vec was given as a single intravenous infusion followed by up to 5 intratumoral injections. Results have been published (see below). In summary, Pexa-Vec was well tolerated and anti-tumor T cell responses were detected. However, no significant differences between treatment arms were observed for overall survival, response rate and time to progression. Induction of immune responses to vaccinia antigens and HCC associated antigens were observed. The results indicate that the treatment of earlier stage patients might be worth exploring.

ParvOryx is a drug product containing native parvovirus H-1 (H-1PV). Since H-1PV was shown to exert pronounced anti-neoplastic effects in pre-clinical models of pancreatic cancer, the drug appears to be a promising candidate for treatment of this malignancy. ParvOryx02 is a non-controlled, single arm, open label, dose-escalating, single center trial. In total seven patients with pancreatic cancer showing at least one hepatic metastasis are to be treated with escalating doses of ParvOryx according to the following schedule: i) 40% of the total dose infused intravenously in equal fractions on four consecutive days, ii) 60% of the total dose injected on a single occasion directly into the hepatic metastasis at varying intervals after intravenous infusions. The main eligibility criteria are: age ≥ 18 years, disease progression despite first-line chemotherapy, and at least one hepatic metastasis. Since it is the second trial within the drug development program, the study primarily explores safety and tolerability after further dose escalation of ParvOryx. The secondary objectives are related to the evaluation of certain aspects of anti-tumor activity and clinical efficacy of the drug. This trial strongly contributes to the clinical development program of ParvOryx. The individual hazards for patients included in the current study and the environmental risks are addressed and counteracted adequately. Besides information on safety and tolerability of the treatment after further dose escalation, thorough evaluations of pharmacokinetics and intratumoral spread as well as proof-of-concept (PoC) in pancreatic cancer will be gained in the course of the trial (modified from Hajda et al., BMC Cancer 2017, BioMed Central, under the terms of Creative Commons Attribution 4.0 International License (CC BY 4.0)

Aim: Talimogene laherparepvec was administered by intralesional injection into injectable cutaneous, subcutaneous, and nodal lesions at an initial dose of 10⁶ plaque-forming units (PFU) per mL on day 1 followed by a dose of 10⁸ PFU/mL 21 days after the initial dose and every 14 days thereafter. Participants were treated with talimogene laherparepvec until they achieved a complete response, all injectable tumors had disappeared, clinically significant (resulting in clinical deterioration or requiring change of therapy) disease progression beyond 6 months of treatment, per modified World Health Organization (WHO) response criteria, or intolerance of study treatment, whichever occurred first. Primary outcome measure: Correlation Between Baseline Intratumoral CD8+ Cell Density and Objective Response Rate (Time Frame: Intratumoral CD8+ cell density was assessed at Baseline. Response was assessed every 12 weeks until disease progression beyond 6 months of treatment or the start of new anticancer therapy; median time on follow-up was 59 weeks (range 3 - 116 weeks).)

In this study, the hypothesis is that intravenous treatment with oncolytic reovirus pelareorep will prime the tumor microenvironment for checkpoint blockade therapy, thereby increasing PD-L1 expression and the number of new T cell clones within the tumor, both of which are associated with increased response to checkpoint blockade.

The START study is an open-label, non-randomized, first-in-human phase I trial of PeptiCRAd-1 against multiple solid tumors (melanoma, triple-negative breast cancer and NSCLC). This adenovirus-based oncolytic encodes two additional therapeutic transgenes (CD40L, OXO40L), which will be expressed in tumor cells upon infection to further stimulate the innate and adaptive immune response. Moreover, the virus is coated with NY-ESO-1 and MAGE-A3 peptides to direct the immune system against NY-ESO-1 or MAGE-A3-positive tumor cells. Patients will be pre-treated with intravenous cyclophosphamide to enhance the therapeutic efficacy of PeptiCRAd-1, which will be administered intratumorally in six individual doses. PeptiCRAd-1 is combined with immune checkpoint inhibition (pembrolizumab).
