Safety of intratumoral immunostimulatory LOAd703 gene therapy combined with chemotherapy in patients with advanced cancer. (PubMed, Immunooncol Technol) - P1/2 | "LOAd703 was administered every 2 weeks by ultrasound-guided intratumoral injections, combined with a standard-of-care or immune-conditioning gemcitabine-based chemotherapy regimen. A trend of higher interferon-gamma (IFN-γ) plasma levels in the highest LOAd703 dose cohort was observed. The acceptable toxicity associated with LOAd703 and chemotherapy, combined with signs of clinical benefit in poor prognostic cancer patients, warrant further studies."

Intravesical instillation of a TME engineering viral vector increases survival in an orthotropic bladder cancer model (AACR 2025) - "Non-muscle invasive urinary bladder cancer is currently treated with bacillus Calmette-Guérin (BCG) instillations followed by nadofaragene firadenovec-vncg for BCG refractory patients...We hypothesize that LOAd703, the human equivalent to Adm703, may be an interesting option for these patients...In conclusion, TME gene engineering with TMZ-CD40L and 4-1BBL increased survival of mice with orthotopic bladder cancer. Further studies investigating Adm703's effect on the immune system are planned."

Immunostimulatory gene therapy co-expressing immune activators TMZ-CD40L and 4-1BBL with a PD-L1-targeting Affibody molecule to reactivate T cell immunity (AACR 2024) - "Next, an adenovirus vector containing trimerized-CD40L and 4-1BBL (LOAd703), known to upregulate PD-L1 in stimulated dendritic cells, was modified to co-express the anti-PD-L1 Affibody molecule (LOAd724)...In summary, Affibody molecules can be expressed from adenoviral gene vehicles alone or in combination with immunostimulatory genes. Further studies are warranted to understand the role of local PD-L1 blockade in the tumor microenvironment following LOAd724 therapy."

Oncolytic Cell-Based Therapy to Overcome Virus Inactivating Immune Response in Small Cell Lung Cancer Models (ASGCT 2023) - "Through in vitro and in vivo models of humoral immunity-mediated virus inactivation, NSCs.LOAd703 maximized the effect of OV by multiplying the infectious virus particles. They also minimized the blockage of the therapeutic effect of oncolytic viruses (OVs) by the immune barriers and thus protected the OVs from immune mediated inactivation and therefore enhanced the anti-cancer effects."

Immunostimulatory gene therapy targeting CD40/4-1BB in combination with chemotherapy induces an inflammatory gene profile in tumors from patients with advanced disease (AACR 2023) - P1/2 | "In the LOKON002 phase I/II clinical trial (NCT03225989), therapy with LOAd703 (delolimogene mupadenorepvec) is investigated in combination with gemcitabine-based chemotherapy in patients with advanced cancer. In conclusion, LOAd703 therapy in combination with chemotherapy generated an inflamed tumor microenvironment in tumors that are normally seen as immunologically “cold”. Hence, LOAd703 may be able to prime tumors for immune checkpoint inhibitors or other immunotherapies, such as adoptive T or NK cell transfer."

No association between adverse events and response was identified. Anti-adenoviral antibody levels (IgG), which increased in all patients, could not be related to indices of clinical benefit.Based on the safety of LOAd703 at all dose levels studied, as well as evidence of objective clinical activity in patients with advanced pancreatic cancer, further disease-directed studies of intratumoral administration of LOAd703 are warranted."

Immunostimulatory gene therapy with oncolytic viruses potentiates the effect of paclitaxel and cisplatin in ovarian cancer (AACR 2023) - P1/2 | "Ovarian cancer is commonly treated with debulking surgery, followed by a combination of a taxane and a platinum-based chemotherapy. This effect was confirmed in vivo, in which the combination therapy had a better tumor control than the other treatment groups. A clinical trial is ongoing to confirm the effect of adding LOAd703 to different treatment regimes in ovarian cancer (NCT03225989)."
