Assembly Biosciences, Inc. is a biotechnology company, which engages in the development of products for infectious diseases, such as chronic hepatitis B virus and illnesses associated with a dysbiotic microbiome. It focuses on two innovative platform programs: oral therapeutics for the treatment of hepatitis B virus, and the oral synthetic live biotherapeutics candidate. The company was founded by Uri Lopatin and Derek A. Small on October 7, 2005 and is headquartered in South San Francisco, CA.

- PMV Pharmaceuticals is a clinical-stage biotech focused on precision oncology therapies that modulate the p53 tumor suppressor pathway, frequently altered in solid tumors. - The company's pipeline centers on identifying specific mutations and molecular profiles where p53-targeted drugs could deliver clinical benefit, with early trials focused on safety, dosage, and efficacy signals. - As a small-cap Nasdaq listing with a market capitalization of 68.961 million USD, PMV Pharmaceuticals relies on cash reserves, equity issuance, and partnerships to fund its R&D. - Regulatory interactions with agencies such as the FDA are central to the company's trajectory, with positive feedback potentially enabling accelerated pathways for serious or rare cancers.
- Assembly Biosciences reported striking Phase I results for two investigational herpes drugs, with ABI-1179 achieving a 98% reduction in HSV-2 viral shedding and 91% reduction in genital lesions compared to placebo. - The weekly oral drug ABI-1179 exceeded the company's target of 80-85% shedding reduction, while monthly candidate ABI-5366 demonstrated 76% reduction in viral shedding and 88% decrease in confirmed genital lesions. - Both helicase-primase inhibitors showed superior efficacy potential compared to current nucleoside analog treatments, with Assembly planning Phase II trials for ABI-5366 by mid-2026. - Guggenheim analysts called the data "striking" and noted the potential for ABI-1179 to unlock a "blockbuster novel weekly treatment opportunity" for recurrent genital herpes.
- Assembly Biosciences presented positive Phase 1b data for ABI-4334, a next-generation capsid assembly modulator targeting chronic hepatitis B infection, at the AASLD Liver Meeting. - The study demonstrated favorable safety and tolerability profiles with multi-log declines in HBV DNA and pregenomic RNA at both 150 mg and 400 mg doses over 28 days. - ABI-4334 achieved exposures multiple folds above levels required for inhibition of cccDNA formation, supporting engagement of both CAM mechanisms of action. - Under the collaboration agreement with Gilead Sciences, Gilead has the right to opt in for exclusive licensing after reviewing the complete Phase 1b data package.
- Assembly Biosciences has dosed the first participant in the Phase 1b portion of its clinical trial evaluating ABI-1179, a long-acting herpes simplex virus helicase-primase inhibitor for recurrent genital herpes. - The Phase 1b study will assess safety and antiviral activity of weekly oral doses over 29 days, measuring viral shedding rates and HSV-2 DNA levels in participants with recurrent genital herpes. - Both ABI-1179 and ABI-5366 are running concurrent Phase 1b studies with interim data expected in fall 2025, supported by Gilead Sciences collaboration agreement. - The helicase-primase inhibition mechanism targets an essential viral enzyme complex with no host equivalent, potentially offering superior efficacy to current nucleoside analog treatments.
- Assembly Biosciences reported positive Phase 1b results for ABI-4334, a next-generation capsid assembly modulator, showing potent antiviral activity against chronic hepatitis B virus infection. - The 400 mg dose cohort demonstrated mean HBV DNA reductions of 3.2 log10 IU/mL over 28 days, consistent with the 150 mg cohort's 2.9 log10 IU/mL reduction. - ABI-4334 maintained a favorable safety profile with once-daily oral dosing supported by pharmacokinetic data across both dose levels. - The trial completion triggers Gilead Sciences' option to license ABI-4334 for further development under their existing collaboration agreement.
- The U.S. FDA granted Breakthrough Therapy designation to brelovitug from Bluejay Therapeutics in January 2025, accelerating development for this investigational hepatitis D treatment. - Vir Biotechnology's combination therapy tobevibart and elebsiran received both FDA Breakthrough Therapy and EMA PRIME designations in December 2024. - The SOLSTICE Phase 2 trial demonstrated that tobevibart achieved 100% virologic response with 80% of participants reaching undetectable HDV RNA levels by Week 60. - Over 8 pharmaceutical companies are actively developing 10+ pipeline therapies for hepatitis D, addressing significant unmet medical needs in this severe liver condition.
- Assembly Biosciences has dosed the first participant in a Phase 1a trial of ABI-6250, potentially the first oral therapy for chronic hepatitis delta virus infection. - The study will evaluate safety, pharmacokinetics, and target engagement through serum bile acid measurements in healthy participants, with data expected in Q3 2025. - ABI-6250 has shown promising preclinical results with low nanomolar potency across multiple HDV genotypes and potential for once-daily oral dosing.
- Assembly Biosciences reports positive Phase 1a results for ABI-5366, an HSV helicase-primase inhibitor, showing a favorable safety profile. - The drug exhibits an approximate 20-day half-life, supporting potential once-weekly or once-monthly oral dosing regimens. - Phase 1b screening is underway to assess ABI-5366's efficacy in participants with recurrent genital herpes, with interim results expected in H1 2025.
