Are there any cancer drugs that protect you against COVID-19?

Certain cancer drugs that decrease levels of angiotensin-converting enzyme 2 (ACE2) may supply some protection in opposition to infection with SARS-CoV-2, suggests a new study.

These drugs embody TOR/PI3K inhibitors (everolimustemsirolimus, and alpelisib), antimetabolites (decitabine and gemcitabine), mitotic inhibitors (cabazitaxel), and different kinase inhibitors (dasatinib and crizotinib).

The study, performed at the Memorial Sloane Kettering Center (MSKCC), New York City, covered 1701 patients who underwent treatment for cancer throughout the early months of the COVID-19 pandemic, from March 10 by way of Could 28, 2020.

The investigators found that among patients who had been treated with cancer drugs that lower ACE2 levels, there was a considerably lower rate of constructive SARS-CoV-2 tests than among patients who were taking different drugs (7% vs 12.9%).

Research author Michael Foote, MD, a research fellow at MSKCC, stated that the study has some implications. “Many oncologists think that treating patients with certain cancer drugs might result in an increased risk of COVID-19,” he stated Medscape Medical News. “Due to this study, some oncologists might really feel a bit extra comfortable treating a patient with a certain drug from our record throughout the pandemic.”

Furthermore, he recommended the findings might spur new research. “There may be a substantial amount of curiosity in the discovery of latest molecular signaling patterns that the virus makes use of to outlive and replicate,” he said. This discovery of a potential decrease in viral infectivity refers that these explicit compounds might impair particular signaling pathways that SARS-CoV-2 needs to duplicate. “Additional analysis studies can discover these new viral signaling pathways in a lab to higher perceive how the virus replicates and also potentially design new antiviral drugs for all patients, not simply cancer patients,” Foote commented.

The authors note that engineered anti-ACE2 therapies have proven preliminary success as COVID-19 treatments while that pc modeling and in vitro evaluation have predicted that using repurposed antineoplastic brokers that inhibit proliferative signaling pathways hijacked by SARS-CoV-2 might inhibit the exercise of the virus.

For the first part of their study, the staff used computer simulation to determine cancer drugs that were related to decreased ACE2 gene expression. They then evaluated how patients who had been taking these drugs fared throughout the pandemic.

From 1701 study participants, 215 (12.6%) patients obtained an ACE2-lowering antineoplastic drug.

After adjusting for confounders, among patients who obtained an ACE2-lowering cancer drug, the SARS-CoV-2 positivity rate was statistically significantly lower at 7.0% (15 of 215 patients) vs 12.9% (191 of 1486 patients) among those that obtained different therapies.

In particular, using gemcitabine was related to a lower SARS-CoV-2 positivity (odds ratio [OR], 0.42).

Use of ACE2-lowering cancer drugs was not statistically considerably related to hospital admission, hypoxic event, or death among all patients or in the SARS-CoV-2-positive-only subcohort.

The rate of SARS-CoV-2 infections was increased among non-White or Hispanic patients in comparison with White non-Hispanic patients (OR, 1.78).

A lot of the patients in this study (91.3%) had solid tumors while 23.2% of patients had hematologic cancer and 18.3% of patients had a couple of types of cancer.

Foote emphasized that the study is a retrospective evaluation, not a randomized controlled trial (RTC). RTCs are the gold standard for figuring out whether or not a drug works for a patient, he commented.

As well as, these findings come from very early in the pandemic, before COVID-19 vaccines were accessible. “In some ways, this can be a strength of the study, as we assessed the impact of certain drugs on the virus pre-vaccine, so we glimpsed a snapshot of the innate habits of SARS-CoV-2,” Foote said.

Nevertheless, it’s unclear how to apply these findings now that efficient vaccines are available. “Actually, we all know that vaccines are the most effective methods to stop viral unfold,” he added. “The Delta variant has been proven to have a particularly high attraction between the virus and the ACE2 receptor; it’s unknown if our drugs can be efficient in opposition to this variant.”
