AlloVir is a late clinical-stage cell therapy company developing allogeneic VST therapies to treat and prevent devastating viral diseases, leveraging a proprietary virus-specific T cell (VST) therapy platform[19] - The lead product candidate, posoleucel (ALVR105), is a multi-VST therapy targeting six viruses (AdV, BKV, CMV, EBV, HHV-6, JCV) and is in ongoing pivotal Phase 3 trials for virus-associated hemorrhagic cystitis (HC) and adenovirus (AdV) infections, and Phase 2 POC trials for multi-virus prevention in HCT and BKV treatment in kidney transplant[19][20][21] - posoleucel has received PRIME designation from the EMA and two RMAT designations from the FDA, indicating critical medical need and potential for expedited regulatory review[22] - The company's pipeline also includes ALVR106 for respiratory viruses, ALVR107 for chronic HBV, and ALVR109 for SARS-CoV-2 (COVID-19), with ALVR109 development demonstrating rapid response to emerging pathogens[25][31] Overview AlloVir develops allogeneic T-cell therapies for viral diseases, with posoleucel in advanced trials - AlloVir is developing four allogeneic, off-the-shelf VST therapy candidates targeting 12 different devastating viruses[19] - Posoleucel has been granted PRIME designation by the EMA and two RMAT designations by the FDA for the treatment of serious infections caused by its targeted viruses in HCT patients[22] - The company's management team, including CEO Diana Brainard and President/CFO Vikas Sinha, has extensive experience in the biopharmaceutical industry[27][28] Funding Raised | Funding Type | Amount (Millions) | | :------------- | :---------------- | | Private Financings | $156.9 | | IPO | $317.7 | Our Pipeline AlloVir's pipeline includes four allogeneic VST candidates targeting 12 viruses, with posoleucel in Phase 3 - Posoleucel (ALVR105) targets six common viruses (AdV, BKV, CMV, EBV, HHV-6, JCV) and showed a 93% clinical response rate in a Phase 2 POC trial for HCT patients with treatment-refractory infections[31] - ALVR106 is a multi-VST candidate for four respiratory viruses (hMPV, influenza, PIV, RSV), with a Phase 1/2 POC clinical trial initiated at the end of 2021[31] - ALVR107 is designed to target HBV-infected cells for chronic HBV infections, with preclinical and IND-enabling studies to be completed in 2022[31] - ALVR109 targets SARS-CoV-2 and is available for compassionate use requests, demonstrating the platform's ability to respond to emerging viral pathogens[31] Our Strategy AlloVir's strategy focuses on accelerating posoleucel, advancing pipeline, and building a global VST company - Accelerate posoleucel through pivotal and proof-of-concept trials for five indications with no FDA- or EMA-approved effective treatment options, aiming for three ongoing Phase 3 trials in H1 2022[33] - Capitalize on the allogeneic VST platform to advance ALVR106 for respiratory viruses and ALVR107 to cure chronic HBV infections[33] - Strengthen leadership in VST therapies through continuous pipeline expansion, exemplified by the rapid development of ALVR109 for COVID-19[33] - Leverage proprietary Cytokin™ and Cytomatch™ algorithms for efficient donor selection and HLA matching to build a global supply chain and manufacturing network, including utilizing ElevateBio's expertise[33] - Build a fully integrated, global VST therapy company with bench-to-bedside capabilities, initially targeting high-volume transplant centers globally[33] The Immune System and the Role of T Cells T cells are crucial for antiviral immunity; partial HLA matching is vital for effective allogeneic VST therapies - CD8+ 'cytotoxic' T cells kill virus-infected cells, while CD4+ 'helper' T cells produce cytokines for antiviral effects and support CD8+ T-cell survival[35] - T cells recognize viruses via T-cell receptors (TCRs) that selectively bind to 'foreign' viral peptides displayed by compatible human leukocyte antigen (HLA) proteins[36] - Partial HLA matching between allogeneic VST therapy and the patient is essential for infused T cells to selectively kill virus-infected cells and minimize GVHD[37] Transplantation and Immunosuppression Immunosuppressed transplant patients face high viral infection risk, leading to morbidity and mortality - In HCTs, the conditioning process depletes immune cells, making patients highly vulnerable to life-threatening viral diseases until donor stem cells reconstitute a functional immune system[40] - Approximately 90% of allogeneic HCT patients experience at least one viral infection, and over 60% experience reactivation of more than one virus (BKV, CMV, AdV, EBV, HHV-6)[41] - SOT patients require lifelong immunosuppressive therapy, making them vulnerable to viral infections for longer durations, leading to worse outcomes like graft failure despite standard care[42] - Transplant patients represent a segment of a larger immunocompromised population (cancer patients, elderly, young children) who could benefit from allogeneic, off-the-shelf VST therapies[43] Limitations of Current Therapies for Immunocompromised Patients Current antivirals for immunocompromised patients are often ineffective, toxic, or unapproved, needing VST therapies - There are no FDA- or EMA-approved antiviral drugs for the majority of viral diseases targeted by AlloVir's VSTs, and existing antivirals are often ineffective, toxic, or lead to resistance[44] - Prophylactic methods like vaccines are limited in immunosuppressed, elderly, and very young patients who cannot mount effective immune responses[44] - Adoptive transfer of ex vivo expanded VSTs has shown promising preliminary disease outcomes and safety data in over 300 allogeneic HCT patients, with product candidates generally well-tolerated and associated with clinical benefit[45] Our Approach to Allogeneic Off-the-Shelf T-Cell Immunotherapy AlloVir restores viral immunity using off-the-shelf VSTs, enabling rapid multi- and single-virus therapy development - AlloVir's VSTs are generated from a panel of healthy, third-party blood donors, forming a mini-bank that provides HLA coverage to over 95% of targeted patients[48] - The partial HLA match allows infused T cells to recognize and selectively kill virus-infected cells, minimizing GVHD risk[47] - The versatile off-the-shelf VST platform enables rapid generation of therapies for a spectrum of viral diseases, including multi-virus (posoleucel, ALVR106) and single-virus (ALVR109, ALVR107) indications[49] Our Proprietary Allogeneic VST Therapy Process AlloVir's VST process uses Cytokin™ for donor selection, scalable manufacturing, and Cytomatch™ for patient matching - The VST production process involves three steps: virus-specific T-cell profiling and targeted donor selection (Cytokin™), rapid and scalable off-the-shelf VST manufacturing, and customized VST-patient matching (Cytomatch™)[53] - Key advantages include a rationally designed cell bank covering >95% of patients, minimized antigen competition, high yields (hundreds of doses per run), and long-term stability for on-demand availability[55] - Manufacturing is conducted at external cGMP CDMOs and ElevateBio BaseCamp, leveraging ElevateBio's cell therapy expertise[63] Step 1: Profiling T-Cell Responses to Viruses and Donor Selection This step identifies viral antigens and uses Cytokin™ to select optimal donors for a VST mini-bank with >95% HLA coverage - The process identifies immunodominant viral antigens by evaluating the number of donors whose T cells recognize each antigen and the strength of the T-cell response[56] - The Cytokin™ algorithm selects optimal donors to generate VSTs, creating a mini-bank that provides >95% HLA coverage for targeted patient populations[57] - At least two viral antigens are targeted for each virus to generate polyclonal VSTs, minimizing the risk of virus immune escape[56] Step 2: Rapid and Scalable Off-the-Shelf VST Manufacturing Polyclonal VSTs are expanded from donor PBMCs, yielding hundreds of cryopreserved doses for immediate patient access - Polyclonal VSTs are selectively activated and expanded from donor PBMCs using viral antigens over approximately two weeks[60] - The single-step process minimizes antigen competition, preserving polyclonality (CD4+ helper and CD8+ cytotoxic T cells) that recognize multiple viral peptides[61] - Each manufacturing run from an individual donor yields hundreds of cryopreserved product candidate doses, enabling immediate patient access[60] - Manufacturing for clinical trials is performed at external cGMP CDMOs and ElevateBio BaseCamp, leveraging specialized cell therapy expertise[63] Step 3: Cytomatch™ and Immediate Patient Access to Our Allogeneic VST Therapy Cytomatch™ selects optimal, partially HLA-matched VSTs for immediate shipment and infusion, ensuring quick patient access - The Cytomatch™ algorithm guides the selection of the VST line for patient treatment based on HLA matching, with a minimum threshold of two HLA allele matches[64] - Selected VST therapies are rapidly identified, packed, and shipped as cryopreserved, off-the-shelf products, allowing for immediate thawing and infusion without additional manipulation[64] Our Highly Innovative Allogeneic VST Therapy Candidates AlloVir's pipeline includes posoleucel (Phase 3), ALVR106 (respiratory), and ALVR107 (HBV) for unmet needs -
