We are a clinical-stage biopharmaceutical company developing novel immunotherapies for the treatment of cancer. Our pipeline candidates are built on our deep expertise in myeloid biology and cancer drug development. Our product candidates use pattern recognition receptors in the innate immune system to help the body recognize tumor cells for a productive anti-cancer response. Our proprietary Boltbody™ ISAC platform technology combines tumor-targeting antibodies with immune-stimulating linker-payloads. We believe this approach has the potential to create products that work with a patient’s own immune system, resulting in anti-cancer efficacy with good tolerability.
BDC-3042, our dectin-2 agonist antibody program, leverages our myeloid biology expertise to target tumor associated macrophages (TAMs). We have completed enrollment of our dose escalation study without any dose-limiting toxicities and will be reporting results from the Phase 1 study in the second quarter of 2025. Our Pipeline

We are a clinical-stage biotechnology company engaged in the development of hematopoietic stem cell gene therapies for the treatment of solid tumors. We have developed a novel biologic platform that involves the ex-vivo gene transfer of a therapeutic candidate into autologous hematopoietic stem/progenitor cells (“HSPCs”) to deliver immunomodulatory molecules directly to the tumor by infiltrating monocytes/macrophages (Tie2 Expressing Monocytes – “TEMs”). Our technology is designed to turn TEMs, which normally have an affinity for and travel to tumors, into a “Trojan Horse” to counteract cancer progression and to prevent tumor relapse. Our technology is not target dependent, and therefore we believe it can be used as a treatment for a broad variety of cancers. 63
Genenta is an early-stage company developing first-in-class cell and gene therapies to address unmet medical needs in cancerous solid tumors. The Company is initially developing its clinical leading product, Temferon™, to treat glioblastoma multiforme (“GBM”), a solid tumor affecting the brain. The Company intends to continue its clinical trials in Italy and eventually start a clinical trial in Europe and the U.S. to study Temferon™ in other cancers. In June 2023, the Company’s Board of Directors selected metastatic Renal Cell Cancer (“mRCC”) as the second solid tumor indication for Temferon. The Company is currently enrolling patients for a Phase 1 trial in mRCC. The Company has recently completed its Phase 1 trial in GBM and its Phase 2a trial in GBM is ongoing.

BDC-3042 is an agonist antibody targeting dectin-2, an innate immune receptor found on the surface of macrophages. dectin-2 is selectively expressed in TAMs across a broad range of tumor types, including non-small cell lung, head and neck, ovarian, triple-negative breast cancer, and melanoma, among others. Most of these TAMs seem to be immunosuppressive, and agonism of dectin-2 converts them to an immunostimulatory phenotype, inducing pro-inflammatory cytokine production, enhanced phagocytosis, and antigen processing and presentation. A dectin-2 agonist antibody has the potential to convert these immunosuppressive TAMs into tumor-destructive macrophages that elicit productive anti-tumor immune responses. Anti-PD-1 therapies have been shown to upregulate the expression of dectin-2 in tumors, which provides an interesting rationale for exploring this combination.

Our lead product candidate, Temferon, consists of genetically modified HSPCs which use our platform to deliver interferon-alpha (“IFN-α”), within the tumor microenvironment via TEMs (HSPCs differentiated myeloid progeny). The IFN-α reduces angiogenesis, counteracts tumor cells proliferation and breaks the established immune-tolerance, enabling the immune system to recognize the tumor. IFN-α is a proven and known immunomodulatory molecule, or cytokine, that has limited clinical use due to the systemic toxicity associated with its intravenous administration. Our technology is designed to protect the HSPCs from IFN-α mediated activation that could negatively impact their repopulation capacity as reported in some studies of repeated systemic administration of high doses of IFN-α.
The investigational treatment involves the use of autologous CD34+-enriched hematopoietic progenitor cells genetically modified with a lentiviral vector encoding human interferon-α2. This therapy is specifically targeted at adult patients aged 18 to 70 years with GBM characterized by an unmethylated O-6-methylguanine-DNA methyltransferase (MGMT) gene promoter, a subgroup known for poorer response to standard therapies. We believe this trial represents an innovative strategy for modulating the tumor microenvironment and enhancing anti-tumor immunity in GBM patients.

In preclinical mouse cancer models treated with Temferon both direct (anti-angiogenic, pro-apoptotic) and indirect (immune response) effects were observed. We are currently developing Temferon for the treatment of glioblastoma multiforme (“GBM”) in patients who have an unmethylated MGMT gene promoter (“uMGMT-GBM”). GBM is the most common malignant primary brain tumor, accounting for more than half of all central nervous system cancers. Patients suffering from GBM have limited, non-curative treatment options. Although these treatments may improve survival, the prognosis for GBM patients remains poor, with a median overall survival (“mOS”) of approximately 13 to 15 months and only 5.5% of patients estimated to be alive five (5) years after diagnosis. With no curative treatments available and such poor prognosis for patients, there remains a large, unmet medical need.
We are currently conducting two Phase 1/2a studies in Italy, to primarily evaluate the safety and tolerability of Temferon. We have completed the Phase 1 portion of the TEM-GBM Phase 1/2a study, which administered escalating doses of Temferon to GBM patients with an unmethylated MGMT promoter following radiotherapy. The study generated encouraging preliminary evidence of potential disease modification, including an increase in the percentage of long-term survivors (LTS) at two years compared to data reported in literature and from a registry which included matched patient population undergoing standard of care.

Our lead product candidate, Temferon, was developed using our proprietary platform and carries the interferon-alpha (“IFN-α”) payload. IFN-α is a well-known therapeutic that was previously administered intravenously for treatment of various cancers, but it is currently rarely used because of its systemic toxicity. The Temferon-modified TEMs express the transgene payload, IFN-α, in the tumor microenvironment, thereby reprogramming the Tumor Micro Environment (“TME”) which disrupts tumor induced immune-tolerance in blocks. Consequently, the immune system has been observed to recognize the tumor, respond, and inhibit tumor growth. Because Temferon is designed to deliver the IFN-α payload directly into the tumor, we believe it will demonstrate clinical activity without the side effect profile of systemic delivery of IFN-α.
In preclinical mouse cancer models treated with Temferon both direct (anti-angiogenic, pro-apoptotic) and indirect (immune response) effects were observed. We are currently developing Temferon for the treatment of glioblastoma multiforme (“GBM”) in patients who have an unmethylated MGMT gene promoter (“uMGMT-GBM”).

Behind the comparison

Sources and methodology

Price return uses split-adjusted daily closes and excludes dividends. Both stocks start on the first shared trading day within the selected window. Unavailable metrics leave gaps.

Financials use SEC canonical statements available by the displayed cutoff, retaining each company's fiscal period end. Annual and quarterly amounts are shown separately. P/E is unavailable when earnings do not support a positive ratio.

Business overlap uses industry tags from annual filings released in 2025. Each core activity receives full weight; each material activity receives one quarter of that weight. Rarer industries carry more weight. We sum the smaller exposure for each shared activity and divide it by the sum of the larger exposure for every activity in either company. This measures business overlap, rather than price correlation or expected returns.

Related comparisons require a shared specific core activity and at least 20% overlap. Broad categories alone do not establish a close peer relationship. Identical classifications can score 100% even when companies sell different products. We select up to ten leading peers per issuer for discovery, combine both directions, and require current common shares, public company profiles and stored price observations. Arbitrary stock pairs remain available.
