Inhalon Biopharma is a clinical-stage biotechnology company developing a proprietary inhaled antibody platform for treating acute respiratory infections. Their technology involves aerosolized muco-trapping antibodies designed to trap viruses in the airway mucus, preventing local spread and enabling rapid clearance from the lungs through the body's natural mucus clearance mechanisms.
Inhalon's lead product candidate is IN-006, an inhaled formulation of the monoclonal antibody regdanvimab, initially developed by Celltrion for intravenous administration against SARS-CoV-2. In October 2021, Inhalon initiated a Phase 1 trial of inhaled IN-006 in healthy subjects, supported by a USD 7 million award from the US Army Medical Research & Development Command (USMRDC). Results from this study demonstrated exceptional pharmacokinetics and safety of inhaled antibody delivery.
Building on this success, Inhalon secured an additional USD 5.7 million USMRDC contract in November 2023 to develop a broad-spectrum inhaled antiviral for prophylaxis and treatment of current and future SARS-CoV-2 variants. The company also expanded its pipeline through a licensing agreement with the University of Georgia in November 2023, acquiring antibodies against human metapneumovirus (hMPV) for clinical development.
Inhalon's self-administered inhaled therapies offer advantages over intravenous delivery, including simplified administration, storage, and distribution, while potentially reducing healthcare resource utilization. The company's patented technology enables lower dosing requirements compared to intravenous antibodies.

 ADC Therapeutics is a clinical-stage biotechnology company focused on developing and commercializing next-generation antibody-drug conjugates (ADCs) for treating cancer. The company's ADCs leverage highly potent and targeted pyrrolobenzodiazepine (PBD) dimer technology, which causes the ADCs' antibodies to bind to specific tumor cell surface antigens. Once internalized, the potent PBD dimer is released inside the cell, creating covalent cross-links between the DNA strands, disrupting cell division without triggering DNA repair mechanisms.
 
 
 
 
 ADC Therapeutics' lead product candidate, Zynlonta, received FDA approval in April 2021 for treating adult patients with relapsed or refractory diffuse large B-cell lymphoma after two or more lines of systemic therapy. The company is also advancing a deep pipeline of other PBD-based ADCs targeting hematologic malignancies and solid tumors. As of May 2021, ADC Therapeutics reported revenues of USD 38.2 million, reflecting initial sales of Zynlonta.
 
 
 
 
 In March 2022, ADC Therapeutics acquired US commercial rights to Overrkey Biological's anti-HER2 ADC Overena, broadening its cancer treatment portfolio. The acquisition aligned with the company's strategic focus on expanding globally with its PBD-based ADC technology.

Sirnaomics is a biopharmaceutical company engaged in the discovery and development of RNA therapeutics. The company focuses on innovative drugs for indications with unmet medical needs and large market opportunities. Sirnaomics utilizes two proprietary delivery platforms: the Polypeptide Nanoparticle Formulation (PNP) and the second generation of GalNAc conjugates called GalAhead.
Sirnaomics has established a robust pipeline of drug candidates, with several products in clinical and preclinical stages. The company's lead clinical product, STP705, has demonstrated positive results in Phase II clinical trials for the treatment of squamous cell carcinoma in situ (isSCC) and basal cell carcinoma (BCC). Additionally, STP705 is being explored for focal fat reduction in the medical aesthetics field. Another promising candidate, STP707, is a PNP formulation consisting of two siRNAs targeting TGF-β1 and COX-2 for intravenous treatment of solid tumors. STP707 has shown promising results in a Phase I basket clinical study, exhibiting stable disease response in 74% of evaluable patients.
Sirnaomics achieved a significant milestone by advancing STP122G, the first candidate utilizing the GalAhead technology, into clinical development. STP122G targets Factor XI for anticoagulation therapeutics and is currently undergoing Phase I clinical trials.
In March 2023, Sirnaomics' subsidiary, RNAimmune, received IND clearance from the FDA to initiate a Phase I clinical trial for RV-1770, an mRNA vaccine targeting respiratory syncytial virus (RSV). Additionally, RNAimmune obtained FDA clearance for a SARS-CoV-2 vaccine booster candidate, RV-1730.
