MHRA approves Evusheld for COVID-19 prevention

25th March 2022

Evusheld is a combination of two monoclonal antibodies which has been approved by the MHRA for the prevention of COVID-19

Tixagevimab/cilgavimab (Evusheld) is a combination of two monoclonal antibodies that has been approved by the UK’s MHRA for use before exposure to COVID-19 in order to prevent the disease. The drug would therefore be most suited to adult patients who are unable to mount a sufficient immune response after receiving a COVID-19 vaccination or alternatively, patients for whom vaccination is not recommended.

Evusheld was issued an emergency use authorisation (EUA) by the FDA in the US in December 2021 for the pre-exposure prophylaxis (prevention) of COVID-19 in certain adults and paediatric individuals (12 years of age and older weighing at least 40 kilograms. However, the combination would not be suitable for those currently infected with COVID-19 or who have had a recent and known exposure to someone infected with the virus. The two components of Evusheld are available as separate intramuscular injections and research has shown that these recognise non-overlapping sites and are simultaneously bound to the S protein and neutralise the wild-type COVID-19 virus in a synergistic manner. As a result, the manufacturer, AstraZeneca, has examined the value of Evusheld in three separate clinical studies.

Evusheld clinical efficacy

To date, none of the three major clinical studies have been fully published and the efficacy data has been made available in press releases from the manufacturer. Evusheld was examined in the PROVENT trial which was designed to assess the safety and efficacy of a single dose compared to placebo for the prevention of COVID-19. The trial included 5,197 participants and who were randomised 2:1 to a single 300 mg dose of Evusheld (AZD7442 in all press releases) or placebo and which was administered in two separate, sequential IM injections. The trial recruited individuals 18 years of age and over (including 43% who were older than 60 years of age) who would benefit from prevention and were defined as having an increased risk for an inadequate response to active immunisation or having an increased risk for COVID-19 infection. Participants at the time of screening were unvaccinated and had a negative COVID-19 test. The primary efficacy endpoint of the trial was the first case of any COVID-19 PCR confirmed, symptomatic illness occurring after the dose before day 183. According to a press release from the manufacturer, Evusheld reduced the risk of developing symptomatic COVID-19 by 77% (95% CI 46 – 90%) in comparison to those given a placebo.

A second trial, STORM CHASER, was designed to explore post-exposure prophylaxis of COVID-19 in Adult patients. The trial included 1,121 participants, randomised 2:1 as before to either Evusheld or placebo, all of whom tested negative for COVID-19 prior to receiving treatment. Again, in a press release from the manufacturer, Evusheld reduced the risk of developing symptomatic COVID-19 by 73% (95% CI 27 – 90%) compared with placebo among those who were PCR negative at the time of dosing.

The third trial, TACKLE, explored the value of Evusheld given to adults who were non-hospitalised with mild-to-moderate COVID-19 and symptomatic for seven days or less, but this time, given a 600 mg dose of the drug. The primary efficacy endpoint of the trial was the composite of either severe COVID-19 or death from any cause through day 29. According to the manufacturer press release on TACKLE, Evusheld given to participants within five days of symptom onset, saw a 67% reduced risk of developing severe COVID-19 or death compared to placebo.

On the basis of these findings, the MHRA has approved the drug and in Europe, the EMA is currently evaluating the combination.

Atezolizumab approved by MHRA for non-small cell lung cancer

4th February 2022

Atezolizumab (Tecentriq) has been approved by the MHRA for use in England for the treatment of non-small cell lung cancer (NSCLC)

Atezolizumab (Tecentriq) has been approved by the Medicines and Healthcare products Regulatory Agency (MHRA) for patients with non-small cell lung cancer (NSCLC).

Around 85% of lung cancers in the UK are due to NSCLC and according to the World Health Organization, there were 2.21 million cases of lung cancer in 2020 and which resulted in 1.80 million deaths. Moreover, 5-year survival among those with NSCLC is poor, with data from England showing that only around 3 in 20 people survive to five years after their diagnosis.

Immunotherapy, which is a novel method of lung cancer treatment, uses monoclonal antibodies directed against immune-checkpoint molecules including the programmed cell death 1 (PD-1) receptor or its ligand (PD-L1). In the UK, NICE has approved atezolizumab (Tecentriq) as an option for untreated metastatic NSCLC in adults if their tumours have PD-L1 expression on at least 50% of tumour cells or 10% of tumour-infiltrating immune cells and where tumours do not have epidermal growth factor receptor (EGFR) or anaplastic lymphoma kinase (ALK) mutations. The MHRA has decided that atezolizumab (Tecentriq) can be used in whose have undergone surgery and chemotherapy as such patients are at risk of cancer relapse.

Atezolizumab (Tecentriq) clinical efficacy

Data on the effectiveness of atezolizumab comes from the IMpower010 clinical trial, a Phase III, global, multicentre, open-label, randomised study designed to compare the efficacy of atezolizumab treatment versus best supportive care in participants with Stage IB-Stage IIIA NSCLC following resection and adjuvant chemotherapy. The trial recruited 1005 patients who were randomised to atezolizumab (n=507) or best supportive care (n=498). After a median follow-up of 32·2 months, atezolizumab treatment improved disease-free survival compared to best supportive care (hazard ratio, HR = 0·66, 95% CI 0·50–0·88, p=0·0039), i.e., the risk of recurrence, new primary NSCLC, or death with atezolizumab was reduced by 34% compared to best supportive care. In a further trial, IMpower110, the efficacy of atezolizumab combined with cisplatin or carboplatin chemotherapy and with either pemetrexed (non-squamous disease) or gemcitabine (squamous disease) in PD-L1-selected, chemotherapy-naïve participants with Stage IV non-squamous or squamous NSCLC. The published results showed that the median overall survival was 7.1 months longer in the atezolizumab group than in the chemotherapy group (20.2 months vs. 13.1 months).

According to the NHS, more than 850 patients in England are expected to be eligible for the drug in the first year and this is predicted to rise to more than 1000 in the third year. Amanda Pritchard, chief executive of NHS England, said, “The NHS has a strong track record of securing rapid access to cutting-edge, new treatments for our patients, and this is the latest rapid access agreement that places an innovative treatment in the hands of frontline NHS staff, supporting them to continue to deliver world-class patient care.”

Kaftrio approval for cystic fibrosis extended by EMA from 6 years of age

17th January 2022

Kaftrio, which represents a triple therapy for patients with cystic fibrosis, can now be used in children from 6 years of age

Kaftrio has been granted an extension to its marketing authorisation by the European Medicines Agency (EMA) for children as young as age 6 who have cystic fibrosis (CF) and at least one F508del mutation in combination with ivacaftor.

Kaftrio is a combination treatment containing 75mg ivacaftor, 50mg tezacaftor and 100mg elexacaftor and is already indicated in a combination regimen with ivacaftor 150mg tablets for the treatment of CF in patients aged 12 years and older who have at least one F508del mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene.

CF is a rare, monogenic disease (i.e., caused by variation in a single gene) which is thought to affect at least 100 000 people worldwide. The condition is best described as a progressive, multi-organ disease that affects the lungs, liver, pancreas, GI tract, sinuses, sweat glands, reproductive tract and a reduced life expectancy. However, according to Cystic Fibrosis, the life expectancy of children born today is likely to surpass 50 years for the first time.

CF is caused by mutations in the genes responsible for encoding of the cystic fibrosis transmembrane conductance regulator (CFTR) protein. This defect results in a reduced chloride secretion and increased sodium absorption through epithelial sodium channels and removal of water from secretions, which therefore become abnormally viscous. Although more than 2000 gene variants of the disease have been discovered, the most predominant is the F508del mutation.

The three drugs present in Kaftrio work in combination. For example, ivacaftor functions as a potentiator of the CFTR protein for common gating mutations, allowing for an increase in chloride ion flow. Tezacaftor ensures correct folding and presentation of the mature CFTR protein to the cell surface, improving CFTR function for the F508del mutation. Finally, elexacaftor is also helps to ensure correct folding of the CFTR protein but acts at an alternate binding site to tezacaftor on the CFTR protein. Overall, this triple combination increases the function of the F508del mutated CFTR protein at the cell surface resulting in increased chloride ion transport and ultimately help hydrate and clear mucus from the airways.

Clinical data already support the use of Kaftrio in children aged 12 years and over though a more recent study demonstrated the combination therapy was also effective in children from 6 years of age and enabled the EMA to extend its licensed usage. In addition to approval from the EMA, the UK’s Medicines and Healthcare products Regulatory Agency (MHRA) has also confirmed the same license extension for Kaftrio.

Skyrizi receives MHRA approval for psoriatic arthritis

2nd December 2021

Skyrizi has now received approval from the UK regulator, the MHRA, for use in the treatment of patients with active psoriatic arthritis

Skyrizi (risankizumab) has been approved by the UK regulator, the MHRA, for the use in adults with active psoriatic arthritis. This follows the EMA approval earlier this month.

The Summary of Product Characteristics (SPC) of the drug has been updated to reflect this change, stating that it is indicated either ‘alone or in combination with methotrexate (MTX), is indicated for the treatment of active psoriatic arthritis in adults who have had an inadequate response or who have been intolerant to one or more disease-modifying anti-rheumatic drugs (DMARDs).’

Skyrizi is a monoclonal antibody and blocks the action of interleukin 23, (IL-23), which is believed to play an important role in psoriatic arthritis. The approved dose for risankizumab is 150mg, administered by subcutaneous injection at week 0 and 4, and every 12 weeks thereafter.

The approval was based on data from two clinical studies, KEEPsAKE-1 and KEEPsAKE-2 and although both of the trials included patients with moderate to severe PsA, the populations were slightly different. For example, KEEPsAKE-1 included patients who had with an inadequate respond to one or more DMARDs whereas KEEPsAKE-2 recruited those with an inadequate response to other biologicals. However, both studies had the same primary endpoint of an ACR20 response at week 24. In addition, secondary outcomes included improvements in several clinical manifestations of psoriatic arthritis such as physical functioning (as assessed by the Health Assessment Questionnaire Disability Index [HAQ-DI]) and minimal disease activity (MDA) and both the primary and secondary endpoints were assessed after 24 weeks of therapy.

In KEEPsAKE-1 57.3% of patients receiving risankizumab achieved the primary endpoint at week 24 compared to 33.5% in the placebo group (p < 0.001). Similarly, in KEEPsAKE 2, 51.3% achieved the primary endpoint compared with 26.5% in the placebo arm (P< 0.001).

There were also significantly greater improvements in the secondary outcomes for risankizumab-treated patients. For example, in KEEPsAKE-1, there was a -0.31 change in HAQ-DI compared to -0.11 (placebo) and in KEEPsAKE 2, a change of -0.22, compared to -0.05 in the placebo group (for both differences, p <0.001).

Xevudy (sotrovimab) approved by MHRA for mild to moderate COVID-19

Xevudy (sotrovimab) reduces hospitalisations and death and has been approved by the MHRA for mild to moderate COVID-19 infection

Xevudy (sotrovimab) which is a monoclonal antibody, has been approved by the UK regulator, the MHRA, after data showing that it can reduce the risk of hospitalisation and death in people with mild to moderate COVID-19 infection and who are at an increased risk of developing severe disease.

According to a press release by the manufacturer, GSK who developed the drug in collaboration with Vir Biotechnology, Inc, Xevudy binds to an epitope on COVID-19 shared with SARS-CoV-1 (the virus responsible for SARS). This suggests that the particular epitope is highly conserved and may therefore be less susceptible to mutations and hence development resistance to the therapy.

Clinical efficacy

The manufacturer has embarked on several clinical trials with Xevudy which have included COMET-ICE, which was a phase 3, multi-centre, double-blind, placebo-controlled trial investigated sotrovimab in adults with mild-to-moderate COVID-19 at high risk of progression to severe disease, who are not hospitalised and not requiring oxygen.

COMET-TAIL another phase 3 randomised, multi-centre, open label, non-inferiority trial for the early treatment of mild-to-moderate COVID-19 in high-risk non-hospitalised adult and paediatric patients (12 years of age and older).

Interim results from COMET-ICE have been published in which 583 non-hospitalised, symptomatic COVID-19 patients were randomised, 1:1, less than 5 days after the onset of symptoms and with at least one risk factor for disease progression. Treatment consisted of a single infusion of sotrovimab at a dose of 500 mg or placebo. The results showed that 3 patients (1%) in the sotrovimab group and 21 patients (7%) in the placebo group, had disease progression leading to hospitalisation or death, giving a relative risk reduction of 85% (95% CI 44% – 96%, p = 0.002).

The full results of the COMET-ICE, which included 1057 patients showed that all-cause hospitalisation lasting over 24 hours, or death was significantly reduced with sotrovimab (1%) vs placebo (6%), giving an adjusted relative risk reduction of 0.79 (95% CI, 50% – 91%, p <.001). In other words, Xevudy reduced the risk of hospitalisations for longer than 24 hours or death by 79%.

According to the SPC, Xevudy is indicated for ‘the treatment of symptomatic adults and adolescents (aged 12 years and over and weighing at least 40 kg) with acute covid-19 infection who do not require oxygen supplementation and who are at increased risk of progressing to severe covid infection.’ It should be given as a single 500 mg dose and the SPC adds that ‘It is recommended that Xevudy is administered within 5 days of onset of symptoms of COVID-19.’

In a statement by the MHRA, it is noted that currently, it is uncertain whether the drug is effective against the omicron variant.

MHRA approves Lagevrio (molnupiravir)

5th November 2021

Lagevrio is the first oral, antiviral agent to be issued a conditional marketing authorisation by the UK’s MHRA for the treatment of COVID-19.

The MHRA has given approval to Lagevrio (molnupiravir) for patients with mild to moderate symptoms of COVID-19, to reduce their risk of hospitalisation and death. Although the results of the Phase III clinical trial, MOVe-OUT, are yet to be published, the manufacturer, Merck and Ridgeback, posted interim results in a press release at the beginning of October 2021.

The interim analysis showed that among patients taking lagevrio, 7.3% were hospitalised compared to 14.1% assigned to placebo (risk difference = 6.8, p = 0.0012). In addition, through to day 29 after randomisation, there were no reported deaths among those taking lagevrio compared with 8 in the placebo arm.

The MHRA says that it has undertaken a “rigorous review of its safety, quality and effectiveness” adding that “Lagevrio is most effective when taken during the early stages of infection” hence the MHRA recommends its use as soon as possible following a positive COVID-19 test and within five days of symptoms onset.

According to the Summary of Product Characteristics of the drug, Lagevrio is indicated “for treatment of mild to moderate coronavirus disease 2019 (COVID-19) in adults with a positive SARS-COV-2 diagnostic test and who have at least one risk factor for developing severe illness.” The recommended dose is four 200mg capsules taken every 12 hours for 5 days although the efficacy if taken over a longer period of time is yet to be established.

While approved for use in the UK, both the the FDA and the EMA are currently undertaking a review of the data on Lagevrio and will no doubt make an announcement in due course.

Commenting on the MHRA approval, its chief executive Dr June Crown said “Lagevrio is another therapeutic to add to our armoury against COVID-19. It is also the world’s first approved antiviral for this disease that can be taken by mouth rather than administered intravenously. This is important, because it means it can be administered outside of a hospital setting, before COVID-19 has progressed to a severe stage.”

Use of tepotinib in advanced NSCLC granted via EAMS

16th July 2021

Through its early access to medicines scheme, the UK MHRA has permitted the use of tepotinib for advanced non-small-cell lung cancer.

According to Cancer Research UK, lung cancer is the 3rd most common cancer in the UK with approximately 47,800 new cases every year or 130 every day. There are two different types of primary lung cancer: small cell and non-small cell, with the latter accounting for around 80–85% of all cases. While early detection of non-small cell lung cancer has an excellent prognosis with 5-year survival rates of 70–90%, around three-quarters (75%) of patients have advanced disease (i.e., stages III/IV) at the time of diagnosis. In fact, the one-year survival for patients with stage IV disease is only 19%, dropping to 2.9% at 5 years.

In recent years, it has become apparent that there are molecular abnormalities associated with lung cancer and this has led to the search for treatments specifically directed at these abnormalities. One such abnormality relates to Mesenchymal-epithelial transition (MET) factor gene, which, under normal circumstances, plays a crucial role in various cellular functions. The MET gene encodes for a receptor tyrosine kinase that activates signalling pathways involved in cell proliferation, survival and growth and it is mutations in this gene that drives oncogenic activation. One particular aberration identified in non-small-cell lung cancer is skipping of METex14 whereby substitutions or deletions at intron 13, result in skipping intron 14. MET skipping occurs in approximately 5% of non-small-cell lung cancer cases and the resultant loss of exon 14, increases the concentration of MET protein and which drives activation of downstream signalling that promote tumour development via phosphoinositide 3-kinase pathways.

Tepotinib is an oral MET kinase inhibitor which works by inhibiting MET-dependent downstream signalling pathways. The effectiveness of tepotinib as mono-therapy for patients with metastatic non-small-cell lung cancer with MET exon 14 skipping alterations was examined in the phase II VISION study which was published in May 2020. In this open-label phase 2 study, tepotinib was given as a daily dose of 500mg to patients, 18 years and older, with advanced or metastatic non-small-cell lung cancer, confirmed by either liquid or tissue biopsy, with a MET exon 14 skipping mutation. The primary endpoint was the response rate based on the RECIST 1.1 criteria, which represents a standard way to measure a patient’s response to cancer treatment.

Findings
A total of 152 patients received tepotinib, of whom, 99 had 9 months of follow-up. The response rate was 46% (95% CL 36 – 57%). Moreover, this response rate was consistent for both liquid and tissue-biopsy (48% and 50% respectively) and the response was similar regardless of baseline characteristics or the number of prior treatments. Adverse reactions of grade 3 severity or higher occurred in 28% of patients, including, most commonly, peripheral oedema (7%) although adverse effects led to treatment discontinuation in only 11% of patients. The authors of the VISION study concluded that tepotinib was associated with a partial response in at least half of all patients.

Based on these findings, the MHRA has permitted the use of tepotinib, via the Early Access to Medicines Scheme (EAMS), for patients with advanced non-small-cell lung cancer. While this does not mean that tepotinib is actually licensed for use, the EAMS recognises the potential value of a treatment where there is a high unmet clinical need.
