1
Kite Pharma
Funding: $335.4M
Kite Pharma develops and produces immune-based cell therapies to treat cancer. Each cell therapy developed by the company is individually tailored to each patient and one-time injected. The CAR T-cell therapy manufacturing process involves collecting the patient's white blood cells, isolating and activating the T-cells, modifying the T-cells with a chimeric antigen receptor gene, culturing and expanding the T-cells and administering the modified T-cells to the same patient. Kite has a state-of-the-art manufacturing facility with full production cycle and global logistics network. The company's portfolio includes two drugs for the treatment of blood diseases, specifically diffuse large B-cell lymphoma, mantle cell lymphoma and acute lymphoblastic leukemia. The company's pipeline includes clinical trials for the treatment of lymphoma, myeloma and leukemia. Acquired by Gilead Sciences

Senti Biosciences
Funding: $272.5M
Senti Bio is developing a new generation of cell and gene therapies for cancer patients. The company has created the Gene Circuit Technology Platform to create gene circuits that can be integrated into new drugs with increased precision. These gene circuits allow to precisely destroy cancer cells, spare healthy cells, increase target tissue specificity and/or provide control even after drug administration. Clinical and preclinical studies have demonstrated the efficacy of the identified gene circuits, which target both NK cells and T cells, allowing the company to select the right cell type for each indication. The company's portfolio includes cell therapies targeting difficult-to-treat myelodysplastic syndromes and acute myeloid leukemia, as well as solid tumors.

Azalea Therapeutics
Funding: $100M
Azalea Therapeutics is a biotech company co-founded by Nobel laureate and CRISPR co-creator Jennifer Doudna to develop a revolutionary cancer vaccine - a single injection that reprograms a patient's T cells directly within the body (in vivo). The technology combines virus-like particles (EDVs) for precise delivery of the CRISPR editor and adeno-associated viruses, which allow genes to be inserted into precisely defined sections of DNA. The combination of these technologies enables a single injection that modifies T cells while preserving their natural behavior. The company is also exploring the possibility of applying the technology to hematopoietic stem cells and B cells. Azalea stands out from its competitors thanks to its unique ability to precisely program gene placement in immune cells.

BioVaxys
Funding: $15.2M
BioVaxys develops immunotherapeutic cancer vaccines targeting lymphoma and ovarian cancer. The company develops them using its proprietary DPX delivery platform. Unlike conventional emulsions or lipid nanoparticles that release their contents systemically, DPX is fully synthetic and compatible with peptides, proteins, mRNA, virus-like particles and small molecules. It is ideal for mRNA delivery, remaining localized at the injection site with superior stability compared to LDL. Maveropepimute-S, the company's lead clinical drug based on this platform, demonstrated an overall response rate of 21% and a disease control rate of 63% in recurrent ovarian cancer. In relapsed/refractory DLBL, the combination of MVP-S and Keytruda achieved complete remission in 3 of 6 evaluable patients. This means that no detectable cancer cells remained after treatment.
5
Moderna Therapeutics
Funding: $3.9B
Moderna is a pioneer in developing a new class of drugs based on messenger RNA (mRNA). This new drug platform is based on the discovery that in-vitro engeneered and injected mRNA can direct the body's cellular machinery to produce virtually any protein of interest, from native proteins to antibodies and other entirely new protein constructs with therapeutic activity both inside and outside cells. In other words, mRNA can guide the body to produce its own drugs. Moderna used mRNA to create the first COVID-19 vaccine and is now applying this technology to create vaccines for infectious diseases (influenza, RSV, HSV, etc.), immuno-oncology (melanoma, lung cancer, liver cancer, etc.), rare diseases and autoimmune diseases.
6
Iovance Biotherapeutics
Funding: $1.6B
IOVANCE Biotherapeutics develops personalized autologous cellular immunotherapies using tumor-infiltrating lymphocytes (TILs). A patient's natural TILs are collected and grown outside the body and then administered to the patient in a single dose. Unlike targeted cell therapies, which act on general antigen targets, IOVANCE TILs are engineered to act on specific neoantigens unique to the patient or tumor. IOVANCE's T-cell-based immunotherapy platform has potential application across multiple solid tumor types. The company has two approved drugs for the treatment of metastatic melanoma and metastatic kidney cancer. The company is also conducting clinical trials for the treatment of cervical cancer, NSCLC, endometrial cancer, and head and neck squamous cell carcinoma.
