A Growing Problem, which is Potentially Contributing to Overdose Deaths

By: Marcus J. Hopkins, ADAP Blog Guest Contributor, and Founder & Executive Director of the Appalachian Learning Initiative (APPLI)

In September 2023, alarming data on overdose deaths was published in the Morbidity and Mortality Weekly Report (MMWR). In response, ADAP Advocacy and the Partnership for Safe Medicines (PSM) issued a press release, ADAP Advocacy Calls for More Awareness on Counterfeit Medicines, calling attention to an increase in the infiltration of counterfeit medications into both the legitimate pharmaceutical marketplace and the illicit drug markets. “Unlike counterfeit opioid pills which often kill instantly, counterfeit HIV medications will victimize patients silently and slowly. Treatment failure, with a whole host of health events, will be the only clue a patient and their physician will notice,” stated Brandon Macsata, ADAP Advocacy’s CEO.

There have been two recent very high-profile examples of counterfeit drugs entering the marketplace: Janssen’s Symtuza (darunavir/ cobicistat/ emtricitabine/ tenofovir alafenamide) and Gilead’s Biktarvy (bictegravir/ emtricitabine/ tenofovir alafenamide) and Descovy (emtricitabine/ tenofovir alafenamide).

The Janssen case came to light on December 24th, 2020, when the company released a statement warning patients, providers, and pharmacists that counterfeit versions of their highly effective HIV drug, Symtuza, had entered the consumer market through pharmacies that had purchased their drugs from distributors that were not authorized by Janssen. In an effort to alert consumers, Janssen began distributing information to providers, patients, and pharmacists with pictures and descriptions of authentic Symtuza pills and informing providers and pharmacists to reach out to patients to alert them to be on the lookout for counterfeits.

Similarly, Gilead Sciences announced on August 5th, 2021, that counterfeit versions of Biktarvy and Descovy had made their way to pharmacy shelves, again via unauthorized distributors, and again provided images of authentic pills and packaging to allow patients to better identify counterfeit products.

Both companies responded in similar ways—attempting to educate the consumer population about authentic products while simultaneously working to address unauthorized distributors. Gilead went further in 2022 by announcing that they were working to identify and sue two individuals responsible for leading and orchestrating the scheme. Their investigation found that these two individuals had directed the initial sale through suppliers created solely to sell counterfeit products. Further action was taken when an asset freeze order was unsealed revealing that 50 defendants were added to the suit. Janssen followed shortly after by announcing its own lawsuit.

And then, there’s the illicit drug market…

A September 1st, 2023, MMWR found evidence that the evidence of overdose deaths resulting from counterfeit pills increased from 2.0% in July-September 2019 to 4.7% in October-December 2021. Fentanyl was the only drug involved in 41.4% of deaths with evidence of counterfeit pill use and 19.5% of deaths without evidence.

The issue, here, isn’t that patients are purchasing counterfeit prescription drugs from pharmacies, but that they’re purchasing them from illicit sources (e.g., illicit drug dealers). And yet, these are still counterfeit versions of legitimate pharmaceutical drugs, each designed to look roughly identical to their authentic counterparts—in these cases, primarily oxycodone (the generic version of OxyContin, a powerful and highly addictive pain medication) and alprazolam (the generic version of Xanax, a drug used primarily to treat anxiety or panic attacks, and one of the most addictive benzodiazepine medications on the market).

Unlike HIV or specialty medications that have very specific, patented designs, both oxycodone and alprazolam have generic equivalents that can make spotting counterfeit versions more difficult. In September 2021, the U.S. Department of Justice's Drug Enforcement Administration (DEA) put out a fact sheet with an image showing the similarities between authentic and counterfeit oxycodone, and the reality is that, unless someone is actively examining each pill they take, the differences are hard to spot. At first glance, the counterfeit version looks like it’s more authentic than the real M30 tablet because the markings are clearer and easier to read.

A bigger concern, here, is that the pills that are shown to have the highest likelihood of being counterfeited are ones to which people may be highly addicted, making them less likely to check pills for authenticity, rather than to just take the pills, either orally or via smoking, the most common non-ingestion drug use route among deaths with evidence of counterfeit drug use (39.5%). This can be exceptionally dangerous, particularly among younger people who are less likely to have experience identifying and avoiding counterfeit drugs. Moreover, those with severe addictions may be driven more by the need to satiate their need than any concerns about potential overdose risks.

Two of the findings from the MMWR report were that overdose deaths with evidence of counterfeit pill use were significantly more likely to occur among young people, with 57.1% of said overdoses occurring in people aged younger than 35 and were more often to occur in Hispanic or Latino populations (18.7%). If these young people are anything like I was in my twenties, they’re not likely to check the provenance of their drugs, rather than just take them.

Additionally, this increase in overdoses impacts a region that has traditionally seen relatively few fentanyl-based overdose deaths compared to the South, Midwest, and New England: the West (Hernandez, 2023). When looking at states in the West, the rate of overdose deaths with evidence of counterfeit pill use surged from 4.7% to 14.7% in the time period examined. Researchers indicate that the type of heroin prevalent in the West—black tar heroin—is difficult to mix with white powder fentanyl, which has made it less likely to be found in Western states. Counterfeit medications, however, make it easier to introduce fentanyl into the market.

Outside of the United States, it was announced on October 24th, 2023, that several people living in Austria were hospitalized after using suspected counterfeits of the blockbuster diabetes and weight loss drug Ozempic (semaglutide). Ozempic, made by Danish company Novo Nordisk, has been shown to drastically improve weight loss outcomes and was approved by the U.S. Food & Drug Administration (FDA) for that purpose under the brand name Wegovy. The drug’s popularity for weight loss purposes has exacerbated supply chain issues, causing worldwide shortages of the drug for patients living with diabetes. Counterfeiters are recognizing these shortages as an opportunity to bring fake versions of the injector pens to the market packaged in official boxes. Authorities in Germany and Britain have been investigating cases where a wholesaler in Austria sold these counterfeits to Germany and to two additional wholesalers in Britain. Here in the United States, similar reports of counterfeit Ozempic were reported in August 2023.

What makes counterfeit pills so dangerous is that people have come to trust in the security of pills. We assume that medications in pill form are guaranteed to be safe, even when we purchase them from illicit sellers, and we do so because we’ve been told by numerous agencies that they are safe, from the FDA who approves them to the manufacturers, providers, and pharmacists who sell them. We also assume, when we buy pills from illicit sources, that they have procured those pills from legitimate sources and are just reselling them. When counterfeit pills enter the market, whether credible-looking fakes of specialty medications or convincing fakes of generic drugs, patients begin to lose trust in the system that fails them…assuming they’re still alive to lose that faith..

Rapid HIV Transmission Clusters

By: Ranier Simons, ADAP Blog Guest Contributor

Despite the many medical and scientific advances in the fight against HIV/AIDS, the numbers of new infections and AIDS-related deaths remain markedly high. Globally, in 2021, there were 1.5 million new infections and 650,000 AIDS deaths.[1] Avoidable HIV infections occur among developing and first-world countries, including the United States. The U.S. Centers for Disease Control & Prevention (CDC) reported one such troubling trend in the September 23, 2022, Morbidity and Mortality Weekly Report (MMWR): clusters of rapid HIV transmission among gay, bisexual and other MSM (men who have sex with men).

MSM accounted for 68 percent of new HIV diagnoses in the United States, in 2020. The recent MMWR report examined clusters of rapid HIV transmission identified by the National HIV Surveillance System (NHSS). The NHSS is the primary source for monitoring HIV in the United States. The surveillance system gathers, analyzes, and reports a plethora of information regarding new and existing HIV infections. The CDC provides funding and partners with local and state health departments to collect the data.[2] Part of this data includes HIV-1 nucleotide sequences taken from the bloodwork of infected individuals. Utilizing this database, researchers identified large molecular clusters of rapid transmission. In other words, they could identify clusters of people who shared the same ‘flavor’ of the HIV virus.

But as the ADAP Advocacy Association noted several years ago, NHSS also is associated with numerous patient concerns, namely privacy infringement and fueling stigma. Whereas some public health advocates may argue such surveillance is necessary in the fight against HIV/AIDS, others remain skeptical whether the benefits outweigh the risks. For the purpose of this particular blog, that debate will be set aside.

Identifying clusters enables public health professionals to identify demographic and geographic areas of HIV transmission. One hundred and thirty-six rapid transmission clusters were identified during 2018-2019 and followed through to December 2021. Rapid transmission was defined as a cluster with five or more diagnoses in the most recent 12 months.[3] A large cluster was defined as one that grew to contain more than 25 people as of December 2021. Thirty-eight large clusters were detected in 2018-2019. MSM comprised the majority of 29 of those 38 clusters. Also, most clusters of rapid HIV transmission were among MSM. The median growth rate was nine people added to a cluster per year.[3] The MSM majority clusters existed in many different regions of the country, most involving multiple states.

There were 2,901 people in the 136 molecular clusters with rapid transmission. The 38 large clusters contained 1,533 (53%) of the 2,901. The 29 clusters of those 38, which were primarily MSM, contained 985 people. Six clusters were primarily people who injected drugs, and three had no defined transmission category.

Concerning racial or ethnic groups, as of December 2021, African-Americans were the largest group in 13 of the large MSM clusters, Caucasians were the largest group in nine of the clusters, and Hispanic people were the largest in seven of them.[3] Geographically, the most common region in 14 of the 29 MSM clusters was the South, and 23 clusters included people from multiple regions.[3] As a whole, 70 % lived in large centralized metropolitan areas or large fringe metropolitan areas, and 20% lived in medium metropolitan regions.[3]

Clusters indicate areas where intervention efforts are not successful. Continuing cluster analysis will demonstrate how treatment, prevention, and testing efforts must be modified to be more effective in the affected communities. The rate of transmission in the large MSM clusters was six times the overall U.S. population average for transmission.[3] Approximately 80% of new HIV transmissions are from people unaware of their status or not receiving regular care.[4] The September report is a wake-up call to the desperate need for an effective concerted, multi-pronged social, political, and financial revolution if we are to reach the goal of eradicating HIV.

HIV & Monkeypox: More Answers Yield Even More Questions

By: Ranier Simons, ADAP Blog Guest Contributor

As the current Monkeypox outbreak continues to develop, so does ongoing research and discourse. A previous blog post, HIV & Monkeypox: What Patients Need to Know,[1] discussed early research regarding possible connections between HIV and Monkeypox. One main takeaway was that clinicians need to expand the list of symptoms they look for in Monkeypox infections. The current outbreak is not behaving as it has historically in the areas of Africa where it is endemic. Symptoms and related conditions can be mistaken for other sexually transmitted infections (STI's) or other illnesses. Additionally, it was noted that clinicians should adopt a heightened caution and suspicion of Monkeypox disease in at-risk groups. Recent research strongly reinforces the need for clinicians to increase their efforts to look for monkeypox disease in at-risk populations and the need for targeted education and messaging.

A report published September 9, 2022, in the U.S. Center for Disease Control & Prevention's (CDC) Morbidity and Mortality Weekly Report (MMWR) shows that people who are HIV-positive or have STI’s are disproportionately represented among those infected with Monkeypox.[2] Data from health departments in eight different U.S. jurisdictions was analyzed to examine Monkeypox clinical differences regarding HIV and STI status. Out of the 1,969 people infected with Monkeypox, who were 18 years of age or older, 38% (755) were HIV-positive, 41% (816) had another STI diagnosed in the previous year, and 18% (363) had both.[2] Additionally, those people living with HIV and also infected with Monkeypox had a higher prevalence of having an STI diagnosis in the preceding year than those diagnosed with Monkeypox who were HIV-negative.

A similar study published September 4, 2022, in HIV Medicine with a much smaller cohort was conducted in Germany.[3] In this study, 546 monkeypox infections from 42 sites were analyzed. All of the subjects were men who have sex with men (MSM). There were 256 (46.9%) patients living with HIV, mostly with viral suppression, 232 (42.5%) were taking pre-exposure prophylaxis  (PrEP), and 58 (10.6%) had no HIV infection or PrEP use. 

The likelihood of hospitalization of HIV-positive patients diagnosed with Monkeypox is still unclear. The CDC study indicates that co-infection with HIV may increase the risk of hospitalization but, the German study does not.[4] The CDC study confirmed hospitalization records from around 1,300 out of the 1,969 subjects. Eight percent of those hospitalized were HIV-positive and 3% were not. Conversely, the German study did not show a significant difference in hospitalization rates. Among those 546 men the overall hospitalization rates were 4% regardless of HIV status.

Both studies have limitations thus, cannot be used to provide definitive generalizations regarding clinical differences in Monkeypox infections between MSM with or without HIV. However, what is abundantly clear is the increased prevalence of the Monkeypox infections amidst MSM living with HIV, with STI’s or both. Evidence shows the heightened prevalence of HIV in populations that regularly receive HIV and STI health services. Thus, it is imperative that clinicians increasingly offer Monkeypox testing to those being treated for HIV and other STI’s in addition to increasing HIV and STI testing for those being treated for monkeypox.

The ongoing research continues to support the observation that Monkeypox is being spread among MSM through social/sexual networks. Therefore, Monkeypox vaccination as prevention coupled with testing and treatment for HIV, Monkeypox and other STI’s remain to be where efforts need to be focused. The CDC reports that recent findings could lead to expanded Monkeypox vaccination recommendations. The findings may lead to vaccines being recommended for “people with recent STD infections, people with HIV, people taking pre-exposure prophylaxis (PrEP) medications to prevent HIV infection and, possibly, prostitutes”.[5] 

Continuing studies will eventually confirm whether HIV infection definitively causes worse outcomes with those infected with monkeypox and/or if simultaneous HIV/STI infection clinically makes someone  more susceptible to contracting Monkeypox. However, it is simultaneously important to work towards stopping the spread of the disease.
