Arrowhead's pipeline includes 14 clinical-stage investigational medicines, ranging from Phase 1 to Phase 3, and a robust discovery-stage pipeline that generates multiple new clinical candidates each year.

The company's primary products and services include RNAi therapeutics, which are designed to silence specific genes that cause diseases. Arrowhead's RNAi therapeutics are designed to trigger the RNA interference mechanism, which induces rapid, deep, and durable knockdown of target genes. The company's pipeline includes RNAi therapeutics for various diseases, including hypertriglyceridemia, non-alcoholic steatohepatitis (NASH), and alpha-1 antitrypsin deficiency. Arrowhead's RNAi therapeutics are administered subcutaneously and have shown promising results in early clinical trials.

One of Arrowhead's most advanced RNAi therapeutics is plozasiran, which is being developed for the treatment of hypertriglyceridemia. Plozasiran has shown significant reductions in triglyceride levels in Phase 2 clinical trials and is currently being evaluated in a Phase 3 clinical trial. Another RNAi therapeutic in Arrowhead's pipeline is zodasiran, which is being developed for the treatment of NASH. Zodasiran has shown promising results in early clinical trials and is currently being evaluated in a Phase 2 clinical trial.

Arrowhead's competitive position within the industry is bolstered by its robust discovery-stage pipeline and its expertise in RNAi technology. Key competitors include pharmaceutical companies that develop RNAi therapeutics. Arrowhead's customers include pharmaceutical companies, research institutions, and government agencies, and its products are used to treat a variety of diseases.

The company's RNAi Triggers are targeted to reduce expression of various gene targets and are supported by issued patents or patent applications.

Arrowhead's products are regulated by government authorities, including the Federal Food, Drug, and Cosmetic Act (FDCA), the Public Health Service Act, and the regulations promulgated under those statutes. The company must comply with applicable statutes and regulations at the federal, state, and local levels in the United States and in other countries and jurisdictions, including the European Union (EU).

Preclinical studies, including in vitro and animal studies, are conducted by Arrowhead to assess the potential for adverse events and establish a rationale for therapeutic use. The company must submit the results of the preclinical tests, along with manufacturing information, analytical data, any available clinical data or literature, and plans for clinical studies, to the FDA as part of an Investigational New Drug (IND) application.

Human clinical studies, including Phase 1, Phase 2, and Phase 3 clinical trials, are conducted by Arrowhead to evaluate the safety and efficacy of its products. The company must submit progress reports detailing the results of the clinical trials to the FDA and may conduct foreign clinical studies under an IND.

Assuming successful completion of required clinical testing and other requirements, Arrowhead submits the results of the preclinical and clinical studies, along with detailed information relating to the product's chemistry, manufacture, controls, and proposed labeling, to the FDA as part of a New Drug Application (NDA) requesting approval to market the drug product for one or more indications.

The FDA evaluates the NDA and accompanying information, including the results of the inspection of the manufacturing facilities, and may issue an approval letter or a complete response letter. An approval letter authorizes commercial marketing of the product with specific prescribing information for specific indications, while a complete response letter outlines the deficiencies in the submission and may require substantial additional testing or information in order for the FDA to reconsider the application.
