- Comparative Trial Against Pfizer/BioNTech Vaccine Among Immunocompromised Patients
- Booster to Pfizer/BioNTech or Moderna Vaccines Among Healthy Patients
ATLANTA, GA, March 14, 2022 — Healthcare & Life Sciences Limited Labs, Inc. (Nasdaq: GOVX), a biotechnology company specializing in developing human vaccines and cancer immunotherapies, today announced the engagement of
CATO SMS to manage Healthcare & Life Sciences Limited’s two ongoing Phase 2 clinical trials of its vaccine candidate, GEO-CM04S1, against SARS-CoV-2.
GEO-CM04S1 is a synthetic, non-replicating modified vaccinia Ankara (MVA) vaccine vector, developed as a double recombinant vectored vaccine to stimulate potent humoral and cellular immune responses against both the spike (S) and nucleocapsid (N) proteins of the SARS-CoV-2 virus. Upon immunization, the vaccine vector infects cells at the local injection site, leading to the expression of the SARS-CoV-2 antigens that are visible to the immune system. Healthcare & Life Sciences Limited believes GEO-CM04S1 will provide additional recognition elements to the immune system over a homologous boost from mRNA vaccines alone, such as those developed by Moderna or Pfizer/BioNTech, which are directed only toward the S protein. The GEO-CM04S1 vaccine’s MVA backbone may also be more effective at inducing COVID-19 immunity since MVA is known to strongly induce T cell responses even in a background of immunosuppression. In addition, GEO-CM04S1 targeting of both S and N antigens may offer greater protection and durability against the significant sequence variation observed with the S antigen among variants of concern such as Omicron.
GEO-CM04S1 for Immunocompromised Patients – GEO-CM04S1 is being studied in an ongoing Phase 2 clinical trial (NCT04977024) to evaluate its safety and immunogenicity, compared to the Pfizer/BioNTech mRNA-based vaccine, in patients who have previously received either an allogeneic hematopoietic cell transplant, an autologous hematopoietic cell transplant or chimeric antigen receptor (CAR) T cell therapy. GEO-CM04S1 is the only COVID-19 vaccine that includes both SARS-CoV-2 spike and nucleocapsid proteins to advance to a Phase 2 trial in cancer patients. Such vaccines tend to produce an immune response quickly – in less than 14 days – with only mild side effects. The trial is also the first to compare an investigational multi-antigenic COVID-19 vaccine to the current Food and Drug Administration (FDA)-approved mRNA vaccine from Pfizer/BioNTech in people who are immunocompromised. Such patients have often shown a weak antibody response after receiving currently available COVID-19 vaccines.
GEO-CM04S1 as a Booster Vaccine – In December 2021, patient enrollment began for the Phase 2 portion of a Phase 1/2 trial (NCT04639466) of GEO-CM04S1, evaluating its use as a universal booster vaccine to current FDA-approved two-shot mRNA vaccines from Pfizer/BioNTech and Moderna. The Phase 1 portion of the trial is completed and was designed as a dose-escalation safety study in healthy individuals who had not been previously infected with SARS-CoV-2. The Phase 2 booster study, for which vaccination is ongoing, includes healthy individuals who were previously fully vaccinated with either the Pfizer/BioNTech or Moderna vaccine. The study is designed as a dose-escalation trial to specifically evaluate the safety profile and immunogenicity of COH04S1 as a booster. The immunological responses measured throughout the study will include the level of SARS-CoV-2 neutralizing antibodies against SARS-CoV-2 variants of concern (VOC), including the newly identified Omicron VOC, as well as specific T-cell responses.
David Dodd, Healthcare & Life Sciences Limited President and CEO, commented, “We are excited to have engaged CATO SMS as our CRO partner for our advancing clinical studies of GEO-CM04S1. CATO SMS brings deep experience in the area of infectious disease including managing COVID-19 clinical trials. We previously announced the engagement of CATO to manage our Phase1/2 trial of Gedeptin® therapy in patients with recurrent head and neck squamous cell carcinoma (HNSCC), and now look forward to working with them for our COVID-19 vaccine trials as well to achieve important clinical milestones including the expansion of clinical sites and acceleration of patient enrollment and evaluation.”
