GlaxoSmithKline (GSK) says initial tests of the antibody-based Covid-19 therapy it is developing with US partner Vir suggest the drug is effective against the Omicron variant. A GSK statement on Thursday (December 2) said that lab tests and a study on hamsters have demonstrated the sotrovimab antibody cocktail to work against viruses that were bio-engineered to carry a number of hallmark mutations of the new variant. The tests are continuing to confirm the results against all of the Omicron mutations, with an update expected by the end of the year, it added. The antibody is designed to latch on to the spike protein on the surface of the coronavirus, but Omicron has been found to have an unusually high amount of mutations on that protein. "Sotrovimab was deliberately designed with a mutating virus in mind," said Vir chief executive George Scangos, adding that the drug was targeting a region of the spike protein that was highly unlikely to mutate.

British drugmaker GSK said on Tuesday (December 7) its antibody-based Covid-19 therapy with US partner Vir Biotechnology is effective against all mutations of the new Omicron coronavirus variant, citing new data from early-stage studies. The data, yet to be published in a peer-reviewed medical journal, shows that the companies' treatment, sotrovimab, is effective against all 37 identified mutations to date in the spike protein, GSK said in a statement. Last week, another pre-clinical data showed that the drug had worked against key mutations of the Omicron variant. Sotrovimab is designed to latch on to the spike protein on the surface of the coronavirus, but Omicron has been found to have an unusually high number of mutations on that protein. "These pre-clinical data demonstrate the potential for our monoclonal antibody to be effective against the latest variant, Omicron, plus all other variants of concern defined to date by the WHO," GSK chief scientific officer Hal Barron said.

The World Health Organization says it is tracking a few dozen cases of two new sub-variants of the highly transmissible Omicron strain of the coronavirus to assess whether they are more infectious or dangerous. It has added BA.4 and BA.5, sister variants of the original BA.1 Omicron variant, to its list for monitoring. It is already tracking BA.1 and BA.2 - now globally dominant - as well as BA.1.1 and BA.3. The WHO said on Monday (April 11) it had begun tracking them because of their "additional mutations that need to be further studied to understand their impact on immune escape potential". Viruses mutate all the time but only some mutations affect their ability to spread or evade prior immunity from vaccination or infection, or the severity of disease they cause. For instance, BA.2 now represents nearly 94% of all sequenced cases and is more transmissible than its siblings, but the evidence so far suggests it is no more likely to cause severe disease.

AstraZeneca on Wednesday (April 5) said a combination of its cancer drugs Imfinzi and Lynparza met the main goal in a late-stage trial in patients with advanced ovarian cancer. The drugmaker said treatment with a combination of those drugs, along with chemotherapy and bevacizumab - the existing standard of care - improved progression-free survival in newly diagnosed patients with advanced ovarian cancer without certain mutations. Lynparza is jointly developed with U.S.-based Merck & Co as a treatment for breast cancer in early stage with certain mutations. Imfinzi alone, along with chemotherapy and bevacizumab, did not reach statistical significance in its interim analysis, the drugmaker added. Philipp Harter, director, Department of Gynaecology and Gynaecologic Oncology, Evangelische Kliniken Essen-Mitte, Germany and principal investigator for the trial, said: "DUO-O showcases the power of academia and industry collaboration in advancing new treatment combinations for patients with ovarian cancer. I'm grateful for the academic cooperative study groups and patients around the world that made this trial possible and look forward to sharing the results with the clinical community." Susan Galbraith, executive vice president, Oncology R&D, AstraZeneca, said: "While there has been significant progress for patients with advanced ovarian cancer, an unmet need still remains. These data from the DUO-O trial provide encouraging evidence for this this Lynparza and Imfinzi combination in patients without tumour BRCA mutations and reinforce our continued commitment to finding new treatment approaches for these patients. It will be important to understand the key secondary endpoints as well as data for relevant subgroups."

After receiving approval from the National Institute for Health and Care Excellence (NICE), the NHS is preparing to roll out a new combination treatment for brain tumours in children and young people in England. Dabrafenib with trametinib would be the first ever targeted treatment for children (aged 1-17) with gliomas that have a specific genetic mutation, the health service said. The treatment, which can be taken at home, has been found to slow the progression of the disease by over threefold compared to standard chemotherapy in children with low-grade gliomas that have a BRAF V600E mutation. Clinical trials have shown that it causes fewer side-effects than chemotherapy. NICE approved the combination treatment on Wednesday 24 April. It will be available on the NHS in the coming months.

Majority of the most common forms of kidney cancer (clear cell renal cell carcinoma, ccRCC) involves a mutation of the same gene, called PBRM1

The UK Health Security Agency on Friday said it had designated a sub-lineage of the dominant and highly transmissible Omicron coronavirus variant as a variant under investigation. BA.2, which does not have the specific mutation seen with Omicron that can be used as a proxy to easily distinguish it from Delta, is being investigated but has not been designated a variant of concern. "It is the nature of viruses to evolve and mutate, so it's to be expected that we will continue to see new variants emerge," Dr Meera Chand, incident director at the UKHSA, said. "Our continued genomic surveillance allows us to detect them and assess whether they are significant." Britain had identified 53 sequences of the BA.2 sub-lineage as of January 10, with updated figures due to be published later on Friday.

Britain's biotech firm Avacta Group on Monday (January 10) announced halting sales of its Covid-19 rapid antigen lateral flow test AffiDX to replace antibodies in the device and increase its ability to diagnose the Omicron variant. The company stated that AffiDX is capable of detecting Omicron when the virus is present in high numbers in samples, but the sensitivity of the test reduces at lower viral loads. The performance of all rapid antigen tests came under scanner in wake of a large number of mutations in the Omicron variant. AffiDX contains both a proprietary Affimer reagent and a commercially available antibody. The Affimer reagent detects the Omicron variant with the same sensitivity as the Delta variant, and performance of the antibody is paired with the Affimer reagent in the test. This has been affected by the additional Omicron mutations, the firm said. Alastair Smith, chief executive of Avacta Group, said: "Our determination to only provide high quality, high performance diagnostic tests has led us to the correct decision to pause all marketing of the AffiDX® lateral flow antigen test. We have, of course, been unable to market the product in the UK since October 2021, as the product continues to await approval under the new CTDA regulatory process.

BioNTech and Pfizer are to start tests on humans of next-generation vaccines that protect against a wide variety of coronaviruses in the second half of the year. Their experimental work on shots that go beyond the current approach include T-cell-enhancing shots, designed to primarily protect against severe disease if the virus becomes more dangerous, and pan-coronavirus shots that protect against the broader family of viruses and its mutations. In presentation slides posted on BioNTech's website for its investor day, the German biotech firm said its aim was to "provide durable variant protection". The two companies are currently discussing with regulators enhanced versions of their established shot to better protect against the Omicron variant and its sublineages. The virus' persistent mutation into new variants that more easily evade vaccine protection, as well as waning human immune memory, have added urgency to the search by companies, governments and health bodies for more reliable tools of protection. As part of a push to further boost its infectious disease business, BioNTech said it was independently working on precision antibiotics that kill superbugs that have grown resistant to currently available anti-infectives.

Right now it is difficult to make predictions . Influenza viruses have not appeared yet in the Northern Hemisphere. According to the World Health Organization can expect the emergence of flu strains AH1N1 California, it is possible in some areas to meet and flu strains of AH3N2 Perth , which is known to us from two years ago. This is somewhat reassuring that the two flu strains have passed through our society and should have some residual immunity in people who have suffered them . On the other hand , as we know , one of the flu virus is very variable , and should not exclude new mutations. Therefore, to estimate what will be the flu pandemic wave weak or strong by now I can't say.

'Tepotinib' has been recommended by the National Institute for Health and Care Excellence (NICE) to patients with a specific gene mutation of advanced non-small-cell lung cancer (NSCLC). The new potentially life-extending drug is available from Thursday (14 April). It has been recommended for routine use across the NHS in England through Project Orbis, a programme to review and approve promising cancer drugs helping patients access treatments faster. NICE has published its final appraisal document recommending tepotinib (also known as Tepmetko and produced by company Merck Serono Ltd) as an option for treating advanced NSCLC with METex14 skipping gene alterations in adults. People with METex14 skipping alterations of NSCLC make up between 1-2% of all adults with lung cancer in England. Tepotinib, which requires people to take two tablets once daily, provides a new targeted treatment for adults with METex14 skipping gene alterations. Just over 700 people in England would be eligible to receive tepotinib as either a first or second-line treatment.

Senior doctors have called for a crackdown on the sale of home genetic testing kits, following a surge in the number of patients being wrongly informed they are carrying serious genetic mutations.

The National Institute for Health and Care Excellence (NICE) has rejected the use of olaparib on the NHS for treatment of adults with hormone-relapsed prostate cancer with BRCA1 or BRCA2 mutations which has spread to other parts of the body. In a draft guidance issued today (January 5) NICE said evidence around the drug made by AstraZeneca was uncertain and approving it would not be a good use of NHS funds. Current treatment for metastatic prostate cancer that no longer responds to hormone therapy is chemotherapy with docetaxel, cabazitaxel, or radium 223 dichloride - a treatment option for people with symptomatic bone metastases who have already had docetaxel or cannot have it. NICE said: "Clinical trial evidence showed that people taking olaparib have more time before their disease gets worse, and live longer overall, than people having retreatment with abiraterone or enzalutamide. However, retreatment with abiraterone or enzalutamide is not considered effective and is not standard care in the NHS.

The prevalence of Covid-19 infections in England rose to around one in 60 people in the week ending November 27, the Office for National Statistics said today (December 03), led higher by the dominant Delta variant rather than the newly identified Omicron. The prevalence was up from one in 65 reported the previous week, the ONS said, adding that 99 per cent of all coronavirus infections which were sequenced were genetically compatible with the Delta variant. "To date, we have not identified any infections compatible with the new Omicron variant (B.1.1.529) among our survey participants," the ONS said. Prime Minister Boris Johnson has introduced travel restrictions and some mask mandates, with a view to slowing the spread of Omicron while work is undertaken to understand it better. There have been 42 confirmed cases of the variant in Britain, which has mutations consistent with reduced vaccine efficacy.

NHS England is set to roll out a new test this week that will help doctors to spot a rare form of eye cancer in babies in the womb. The NHS test developed at Birmingham Women's and Children's NHS Foundation Trust, identifies the risk of developing retinoblastoma in babies that can be monitored and treated sooner - increasing the chance of saving their eyesight and potentially their lives. The new non-invasive test can detect changes in the genes in DNA and is likely to identify around 50 infants with retinoblastoma each year, in the latest example of the NHS harnessing the power of genomics to diagnose and treat patients faster and more effectively. Non-Invasive Prenatal Diagnosis (NIPD) also means parents can be informed early in pregnancy if their child is at risk. "The blood sample test is taken from the mother before birth and tested and analysed for mutations, which can determine with almost 100 per cent accuracy if the baby will develop retinoblastoma," the NHS said.

Capitalising on strong demand for its obesity therapies, Novo Nordisk's growing appetite for deals has fuelled a bet on a U.S. gene-editing company called Life Edit Therapeutics. The Danish drugmaker's collaboration with Durham, North Carolina-based Life Edit Therapeutics - owned by ElevateBio, a cell and gene therapy company in Waltham - is focused on up to seven programs for rare genetic disorders as well as cardiometabolic diseases. At the heart of the tie-up is Life Edit's technology, called base editing, which is designed to make precise changes to the human genome by tweaking one base - or letter - into a different one without affecting other letters. Single-letter mistakes, called point mutations, can give rise to genetic diseases.
