TRIAL DESCRIPTION
Public title A study to determine if a new vaccine safely generates good immune responses to protect adults in Kenya from Coronavirus Disease
Official scientific title A phase Ib/II single-blinded, randomised, controlled study to determine safety, immunogenicity and efficacy of the candidate Coronavirus Disease (COVID-19) vaccine ChAdOx1 nCoV-19 in adults in Kenya (COV004)
Brief summary describing the background and objectives of the trial As of 11th February 2020, the coronavirus disease (COVID-19) pandemic has affected over 106 million people globally, with over 2 million deaths. The disease has been reported in over 200 countries, including Kenya where over 102,000 cases have been reported. Some of the vaccines approved for emergency use in different regions for use against COVID-19 include Pfizer/BioNTech, Moderna, Sinovac, and ChAdOx1 nCoV-19 among others. As the number of cases continue to rise globally, use of effective vaccines remains the best way to control the pandemic and to safely relax physical distancing and other restrictions. There are over 170 COVID-19 vaccine candidates in development, with 63 of these currently undergoing evaluation in human clinical trials(as of 9th February 2021). Of the 63 vaccines, ChAdOx1 nCoV-19, a candidate vaccine developed by our longstanding collaborators at the University of Oxford in partnership with AstraZeneca, is among the most advanced and has received Emergency Use Authorisation from various national and international regulators, including the World Health Organization (WHO). ChAdOx1 nCoV-19 has shown promise in a range of animal models of COVID-19 disease and has already been administered to over 10,000 adult volunteers in the United Kingdom, Brazil and South Africa (Registration numbers: NCT04324606, NCT04400838, ISRCTN89951424 and NCT04444674). The vaccine has been found to be safe and to provide protection against COVID-19 in these studies. In this single-blinded randomized controlled phase Ib/II study we plan to evaluate the safety and immunogenicity of ChAdOx1 nCoV-19 (5x1010 vp) as compared to rabies vaccine among 400 adults aged ≥18 years. The study will take place in the coastal counties of Kilifi and Mombasa, where high numbers of COVID-19 cases have been detected. The study will enrol frontline staff such as; healthcare workers, allied health professionals, truckers, security personnel, banking personnel, supermarket staff, police, security personnel, prison workers, laboratory technicians, scientists, logistics personnel, public transport workers including aviation industry amongst others. These populations have been prioritised due to their high risk of occupational exposure to COVID-19, hence their urgent need for protection. However, due to the risk of infection from ongoing community SARS-CoV-2 transmission in Kenya, other members of public will also be eligible for the study. Participants will be randomized to receive two doses of either ChAdOx1 nCoV-19 (n=200) or rabies vaccine (n=200). Out of these, 40 will be enrolled in the phase Ib trial, and the remainder to the phase II trial (180 per vaccine). The time interval between the two doses will be 3 months for both phase Ib and phase II. After each vaccination, participants will be required to complete diary cards (paper or electronic) and record any solicited and unsolicited adverse events experienced for 6 days following vaccination while at home. Each participant will have 10 clinic visits in the course of the study and some of the activities that will be carried out will include; physical assessment, checking vital signs, phlebotomy and safety assessment. If found to be safe and effective in generating protective immune responses, the ChAdOx1 nCoV-19 will be further developed for use in controlling COVID-19, including in populations in Kenya and other countries in Africa.

INTERVENTIONS
Intervention type Intervention name Dose Duration Intervention description Group size Nature of control
Experimental Group COVID19 vaccine Two doses of ChAdOx1 nCoV-19 vaccine 5x10^10 vp that will be administered at a 8- to 12-week interval in both phase Ib and II. A longer interval between doses results in better immune responses and higher efficacy and this has informed WHO’s recommendation that two standard doses of ChAdOx1 nCoV-19 be administered at an 8- to 12-week interval. Phase Ib-1 year follow-up Phase II-1 year follow-up Phase Ib and II will be conducted within the same trial, phase II beginning after DSMB review of phase I day 28 data. ChAdOx1 nCoV-19 vaccine consists of the replication-deficient simian adenovirus vector ChAdOx1, containing the structural surface glycoprotein (Spike protein) antigen of the SARS CoV-2 (nCoV-19), with a leading tissue plasminogen activator (tPA) signal sequence. ChAdOx1 nCoV-19 expresses a codon-optimised coding sequence for the Spike protein from genome sequence accession GenBank: MN908947. The tPA leader sequence has been shown to be beneficial in enhancing immunogenicity of another ChAdOx1 vectored CoV vaccine (ChAdOx1 MERS) [5]. Following vaccination, the Spike glycoprotein (S) primes the host immune system to attack the coronavirus in case of any infections. The ChAdOx1 vaccine vector was selected due to its non-replicating nature, making it impossible to cause an infection in vaccinated individuals. As a result, the vaccine would be safe in individuals with pre-existing conditions and age groups at risk of getting the SARS-CoV-2 infection. 200
Control Group Rabies vaccine 0.5 mL of Verorab (rabies vaccine) via the intramuscular route. Two doses that are at an 8-12 week interval. Phase Ib-1 year follow-up Phase II-1 year follow-up Phase Ib and II will be conducted within the same trial, phase II beginning after DSMB review of phase I day 28 data. Verorab (from Sanofi) will be used as the rabies vaccine and it is registered and licensed for use in Kenya. One dose consists in the administration of 0.5 mL of vaccine via the intramuscular route. 200 Active-Treatment of Control Group

Trial Information Trial description 25/05/2020 Updated numbers of COVID-19 cases, and number of participants already vaccinated in the UK. The coronavirus disease (COVID-19) pandemic has so far affected over 3 million people globally, with more than 200,000 deaths. The disease has been reported in over 200 countries, including Kenya where 465 cases had been reported as of 4th May 2020. No vaccines or treatments are currently available for COVID-19. However, there are many COVID-19 vaccine candidates in development, but none of these are in development in Africa and no vaccine trials are currently ongoing in Africa. Vaccine performance from studies in other populations may not be generalizable to Kenya and other African countries. As the number of cases continue to rise globally, an effective vaccine remains the best way to control the pandemic and to safely relax social distancing and other restrictions. A candidate COVID-19 vaccine called ChAdOx1 nCoV-19 has been developed by the University of Oxford, using a platform, termed ‘ChAdOx1’, that is known to be safe in humans based on its use for making vaccines against other diseases. ChAdOx1 nCoV-19 has shown promise in a range of animal models of COVID-19 disease and is currently undergoing clinical trial in humans in the United Kingdom (UK) (ClinicalTrials.gov number: NCT04324606). In this study we plan to evaluate the safety and immunogenicity of ChAdOx1 nCoV-19 vaccine among 400 adults aged ≥18 years. Vaccine efficacy will be evaluated as a secondary objective. The study will take place in the coastal counties of Kilifi and Mombasa, where high numbers of COVID-19 cases have been reported. The study will only enrol healthcare workers (HCWs) including doctors, nurses, clinical officers, pharmacists, mortuary attendants and allied healthcare professionals. HCWs have been prioritised due to their high risk of occupational exposure to COVID-19, hence their urgent need for protection. If found to be safe and effective in generating protective immune responses, the ChAdOx1 nCoV-19 will be further developed for use in controlling COVID-19. The COVID-19 pandemic has so far affected over 5 million people globally, with more than 330,000 deaths. The disease has been reported in over 200 countries, including Kenya where 1214 cases had been reported as of 24th May 2020. No vaccines or treatments are currently available for COVID-19. However, there are many COVID-19 vaccine candidates in development, but none of these are in development in Africa and no vaccine trials are currently ongoing in Africa.

Trial Information Trial description 11/09/2020 Update to background info & study population As of 4th August 2020, the coronavirus disease (COVID-19) pandemic has affected over 18 million people globally, with close to 700,000 deaths. The disease has been reported in over 200 countries, including Kenya where over 23,000 cases have been reported. No vaccines or treatments are currently licensed for use against COVID-19. As the number of cases continue to rise globally, an effective vaccine remains the best way to control the pandemic and to safely relax physical distancing and other restrictions. There are over 150 COVID-19 vaccine candidates in development, with 26 of these currently undergoing evaluation in human clinical trials (as of 4th August 2020). Of the 26 vaccines, ChAdOx1 nCoV-19, a candidate vaccine developed by our longstanding collaborators at the University of Oxford in partnership with AstraZeneca, is the most advanced. ChAdOx1 nCoV-19 has shown promise in a range of animal models of COVID-19 disease and has already been administered to over 5,000 adult volunteers in the United Kingdom, Brazil and South Africa (Registration numbers: NCT04324606, NCT04400838, ISRCTN89951424 and NCT04444674). In this single-blinded randomized study we plan to evaluate the safety and immunogenicity of a single dose of ChAdOx1 nCoV-19 (5x1010 vp) vaccine among 400 adults aged ≥18 years. The study will take place in the coastal counties of Kilifi and Mombasa, where high numbers of COVID-19 cases have been detected. The study will only enrol frontline staff as defined by the government. These populations have been prioritised due to their high risk of occupational exposure to COVID-19, hence their urgent need for protection. Participants will be randomized to receive either ChAdOx1 nCoV-19 (n=200) or rabies vaccine (n=200). Out of these, 40 will be enrolled in the phase Ib trial, and the remainder to the phase II trial (180 per vaccine). After vaccination, they will be required to complete diary cards (paper or electronic) and record any solicited and unsolicited adverse events experienced for 6 days following vaccination while at home. Each participant will have 7 clinic visits in the course of the study and some of the activities that will be carried out will include; physical assessment, checking vital signs, phlebotomy and safety assessment. If found to be safe and effective in generating protective immune responses, the ChAdOx1 nCoV-19 will be further developed for use in controlling COVID-19, including in populations in Kenya and other countries in Africa. As of 11th September 2020, the COVID-19 pandemic has affected over 27 million people globally, with over 900,000 deaths. The disease has been reported in over 200 countries, including Kenya where over 35,000 cases have been reported. No vaccines or treatments are currently licensed for use against COVID-19. As the number of cases continue to rise globally, an effective vaccine remains the best way to control the pandemic and to safely relax physical distancing and other restrictions. There are over 30 COVID-19 vaccine candidates in clinical development. ChAdOx1 nCoV-19, developed by the University of Oxford in partnership with AstraZeneca, is the most advanced. ChAdOx1 nCoV-19 has shown promise in a range of animal models of COVID-19 disease and has already been administered to over 5,000 adult volunteers in the United Kingdom, Brazil and South Africa (Registration numbers: NCT04324606, NCT04400838, ISRCTN89951424 and NCT04444674).

The study will take place in the coastal counties of Kilifi and Mombasa, where high numbers of COVID-19 cases have been detected. The study will only enrol frontline workers in key service areas e.g. healthcare workers, allied health professionals, truckers, among others. These populations have been prioritised due to their high risk of occupational exposure to COVID-19, hence their urgent need for protection. Participants will be randomized to receive either ChAdOx1 nCoV-19 (n=200) or rabies vaccine (n=200).

If found to be safe and effective in generating protective immune responses, the ChAdOx1 nCoV-19 will be further developed for use in controlling COVID-19, including in populations in Kenya and other countries in Africa. As of 11th February 2020, the coronavirus disease (COVID-19) pandemic has affected over 106 million people globally, with over 2 million deaths. The disease has been reported in over 200 countries, including Kenya where over 102,000 cases have been reported. Some of the vaccines approved for emergency use in different regions for use against COVID-19 include Pfizer/BioNTech, Moderna, Sinovac, and ChAdOx1 nCoV-19 among others. As the number of cases continue to rise globally, use of effective vaccines remains the best way to control the pandemic and to safely relax physical distancing and other restrictions. There are over 170 COVID-19 vaccine candidates in development, with 63 of these currently undergoing evaluation in human clinical trials(as of 9th February 2021). Of the 63 vaccines, ChAdOx1 nCoV-19, a candidate vaccine developed by our longstanding collaborators at the University of Oxford in partnership with AstraZeneca, is among the most advanced and has received Emergency Use Authorisation from various national and international regulators, including the World Health Organization (WHO). ChAdOx1 nCoV-19 has shown promise in a range of animal models of COVID-19 disease and has already been administered to over 10,000 adult volunteers in the United Kingdom, Brazil and South Africa (Registration numbers: NCT04324606, NCT04400838, ISRCTN89951424 and NCT04444674). The vaccine has been found to be safe and to provide protection against COVID-19 in these studies. In this single-blinded randomized controlled phase Ib/II study we plan to evaluate the safety and immunogenicity of ChAdOx1 nCoV-19 (5x1010 vp) as compared to rabies vaccine among 400 adults aged ≥18 years. The study will take place in the coastal counties of Kilifi and Mombasa, where high numbers of COVID-19 cases have been detected. The study will enrol frontline staff such as; healthcare workers, allied health professionals, truckers, security personnel, banking personnel, supermarket staff, police, security personnel, prison workers, laboratory technicians, scientists, logistics personnel, public transport workers including aviation industry amongst others. These populations have been prioritised due to their high risk of occupational exposure to COVID-19, hence their urgent need for protection. However, due to the risk of infection from ongoing community SARS-CoV-2 transmission in Kenya, other members of public will also be eligible for the study. Participants will be randomized to receive two doses of either ChAdOx1 nCoV-19 (n=200) or rabies vaccine (n=200). Out of these, 40 will be enrolled in the phase Ib trial, and the remainder to the phase II trial (180 per vaccine). The time interval between the two doses will be 3 months for both phase Ib and phase II. After each vaccination, participants will be required to complete diary cards (paper or electronic) and record any solicited and unsolicited adverse events experienced for 6 days following vaccination while at home. Each participant will have 10 clinic visits in the course of the study and some of the activities that will be carried out will include; physical assessment, checking vital signs, phlebotomy and safety assessment. If found to be safe and effective in generating protective immune responses, the ChAdOx1 nCoV-19 will be further developed for use in controlling COVID-19, including in populations in Kenya and other countries in Africa.

Intervention Intervention List 18/03/2021 The WHO recommends that two standard doses of ChAdOx1 nCoV-19 be administered at an 8- to 12-week interval. The available data shows that a longer interval between doses results in better immune responses and higher efficacy. Experimental Group, COVID19 vaccine, Single dose of ChAdOx1 nCoV-19 vaccine 5x10^10 vp, Phase Ib-1 year follow-up Phase II-1 year follow-up Phase Ib and II will be conducted within the same trial, phase II beginning after DSMB review of phase I day 28 data., ChAdOx1 nCoV-19 vaccine consists of the replication-deficient simian adenovirus vector ChAdOx1, containing the structural surface glycoprotein (Spike protein) antigen of the SARS CoV-2 (nCoV-19), with a leading tissue plasminogen activator (tPA) signal sequence. ChAdOx1 nCoV-19 expresses a codon-optimised coding sequence for the Spike protein from genome sequence accession GenBank: MN908947. The tPA leader sequence has been shown to be beneficial in enhancing immunogenicity of another ChAdOx1 vectored CoV vaccine (ChAdOx1 MERS) [5]. Following vaccination, the Spike glycoprotein (S) primes the host immune system to attack the coronavirus in case of any infections. The ChAdOx1 vaccine vector was selected due to its non-replicating nature, making it impossible to cause an infection in vaccinated individuals. As a result, the vaccine would be safe in individuals with pre-existing conditions and age groups at risk of getting the SARS-CoV-2 infection. , 200, Experimental Group, COVID19 vaccine, Two doses of ChAdOx1 nCoV-19 vaccine 5x10^10 vp that will be administered at a 8- to 12-week interval in both phase Ib and II., Phase Ib-1 year follow-up Phase II-1 year follow-up Phase Ib and II will be conducted within the same trial, phase II beginning after DSMB review of phase I day 28 data., ChAdOx1 nCoV-19 vaccine consists of the replication-deficient simian adenovirus vector ChAdOx1, containing the structural surface glycoprotein (Spike protein) antigen of the SARS CoV-2 (nCoV-19), with a leading tissue plasminogen activator (tPA) signal sequence. ChAdOx1 nCoV-19 expresses a codon-optimised coding sequence for the Spike protein from genome sequence accession GenBank: MN908947. The tPA leader sequence has been shown to be beneficial in enhancing immunogenicity of another ChAdOx1 vectored CoV vaccine (ChAdOx1 MERS) [5].
