Pharma Sources - The Future of Obesity Drugs

1/7/2024

0 Comments

 
The rising levels of obesity worldwide are creating a health challenge. According to the World Health Organization (WHO), the number of adults living with obesity rose by 138% between 1975 and 2016. During the same period, the numbers increased nearly 3-fold in boys and more than doubled in girls aged 15-19 years. Being overweight or obese is linked with cardiovascular diseases, cancer, type 2 diabetes, musculoskeletal conditions and chronic respiratory diseases, and has been associated with over 1.2 million deaths a year in the WHO European Region alone. By the year 2030, over a billion people could be affected by obesity, according to the World Obesity Forum. 

After a shaky history of ineffective or harmful drug treatments for obesity, from laxatives and purgatives in the Greco-Roman period and tobacco in the 16th century, through thyroid hormones in the 19th century and amphetamines in the 20th century, to the now withdrawn drugs rimonabant, sibutramine and lorcaserin in the 21st century, the pharmaceutical industry is exploring new approaches in the journey to find better therapeutics for use in obesity.

Pharma Sources - Microelectromechanical systems (MEMS) in drug delivery

17/5/2024

0 Comments

 
Drug delivery is about improving the efficacy and safety of therapeutics by getting the right dose of the right drug to the right place at the right rate and time. Approaches to drug delivery have existed for many hundreds of years; Egyptian physicians created oral tablets and ointments, and physicians began to use intravenous delivery after the circulatory system was first described in 1657. Controlled release technologies date back to the mid-1900s.

Drug delivery systems range from gels and patches, through microspheres and nanoparticles, to complex devices such as external or implanted pumps and microelectromechanical systems (MEMS).

Pharma Sources - Decentralising research: Virtual clinical trials

14/5/2024

0 Comments

 
Clinical trials are vital as the basis of developing safe and effective drugs, but they can be slow and expensive. The patient burden can also be high - the time taken to travel to the site may be long (as many as 70% of patients may live two or more hours away from a clinical site), and this can be made worse when sites are not near public transport routes. The travel time, combined with the time spent at the clinic for visits, can result in absences from work or school, or issues with caring responsibilities. There are barriers that impact the access to a study for older people, neurodiverse people, people from the LGBTQIA+ community and people from ethnically minoritised groups. All of these can have an impact on recruitment and retention. 

One of the solutions to this could be the virtual clinical trial, also known as remote, digital, decentralised or siteless trials. These have potential to make the drug development process more efficient, more inclusive and more patient-centric, as well as widening the geographic area from which patients can be selected.

Virtual clinical trials are conducted remotely, with data collected from the patient wherever they are, rather than at a specific clinical trial site. The data is amassed in a variety of ways, including telemedicine platforms, and wearable devices and sensors.

The ongoing AMR challenge

6/5/2024

0 Comments

 
The development of antimicrobial agents has saved many lives worldwide since the discovery of penicillin in 1928. However, the spread of antimicrobial resistance (AMR), which occurs when bacteria, viruses, fungi or parasites no longer respond to existing treatments, has limited their use. According to the World Health Organization (WHO), there are 4.95 million deaths every year attributed to AMR. The organization regards AMR as one of the top ten global threats to public life. This piece will focus on antimicrobial resistance in bacterial infections. 
​
AMR in bacteria is a natural survival mechanism. Its spread has been accelerated by the misuse and overuse of antibiotics and antimicrobials in hospitals, the community, particularly in countries where antibiotics are available without prescriptions, and in farming. Beating AMR will need a variety of different approaches, including the development of new antibiotics, the use of monoclonal antibodies, greater use of diagnostics to allow precision prescribing, and vaccinations to prevent the incidence and spread of bacterial infections.

Vaccination for infectious diseases saves two to three million lives a year worldwide, according to the World Health Organization (WHO). Following the implementation of national programmes for immunization in the 1960s and beyond, many of the diseases that caused the majority of childhood deaths, such as diphtheria and polio, virtually disappeared. [1] The story of modern vaccines began with smallpox and Edward Jenner, but the history goes back even further.

Queering clinical research

27/3/2024

0 Comments

 
Picture
In 2021/2022, 3.3% of the UK population identified as lesbian, gay or bisexual, 0.5% identified as transgender and 0.06% identified as non-binary. Globally, up to 1.7% of the population is intersex. Despite these numbers, there is a lack of research into how treatments affect people across the spectrum of sexuality and gender, and this has potential to put people from these communities at risk.
 
Diversity in clinical research is vital in order to ensure that the study results are relevant to as broad a population as possible, and this includes involving people from LGBTQIA+ communities. Accessing the widest possible population will also allow companies to recruit enough people for studies, and therefore move drugs through the development process more quickly, speeding up the time it takes to get to market and into the hands of patients. Improving the inclusivity of clinical research will help everyone to gain equitable access to the most effective and safest forms of treatment.
 
Barriers to taking part in clinical trials
For LGBTQIA+ people, a range of barriers can contribute to making clinical research a less viable option for them.
 
Loss of trust
Many people from the LGBTQIA+ community have had poor experience(s) when accessing and experiencing healthcare. Negative experiences can fuel mis- and dis-trust of healthcare both as a system and the healthcare professionals that work within it. These experiences are highly likely to likely to impact willingness to take part in clinical trials.
 
From a Stonewall survey:
  • One in eight LGBTQIA+ people (13%) have experienced some form of unequal treatment from healthcare staff because of their gender or sexuality
    • This includes one-third of trans people, one third of lesbians, one in five LGBTQIA+ disabled people and one in five ethnically minoritised LGBTQIA+ people
  • One in four LGBTQIA+ people (23%) have witnessed discriminatory or negative remarks against LGBTQIA+ people by healthcare staff
  • One in four LGBTQIA+ people (25%) have experienced inappropriate curiosity from healthcare staff because of their gender or sexuality
    • This includes half of trans people and more than a third of non-binary people
  • One in five LGBTQIA+ people (19%) aren’t out to any healthcare professional about their sexual orientation when seeking general medical care.
    • This includes 40% of bi men and 29% of bi women
  • One in ten LGBTQIA+ people (10%) have been outed without their consent by healthcare staff in front of other staff or patients
    • This includes 27% of trans people and 15% of LGBTQIA+ disabled people
  • One in twenty LGBTQIA+ people (5%) have been pressured to access services to question or change their sexual orientation when accessing healthcare services
    • This includes 20% of trans people, 9% of LGBTQ+ young adults, 9% of ethnically minoritised LGBTQIA+ people and 8% of LGBTQIA+ disabled people
  • One in six trans people (16%) have been refused healthcare
  • One in seven LGBTQIA+ people (14%) have avoided treatment for fear of discrimination
    • This includes 37% of trans people and 33% of non-binary people
 
Other issues include:
  • Going to see a doctor can mean having to explain sexuality or gender identity from scratch each time, and when appointment times are limited, this reduces the time available to discuss medical issues.
  • Medical records that include only male/female options result in misgendering for trans and non-binary people, and making them feel othered by the system.
  
The impact of gender and sexuality
The barriers already discussed show why LGBTQIA+ people overall may be less likely to accept or interact with medical interventions. It goes further, though – the impact of gender and sexuality on healthcare is complex, and it crosses biology, neurodiversity, culture, sociology and current and past medical interactions.
 
These are a few examples:

  • Intersex people may have physical and hormonal characteristics that interact with medical interventions.
  • A proportion of trans and non-binary people are on hormone therapy, and this can affect how their bodies react to various medications, as well as potentially changing their risk factors to hormone-linked diseases. As an example, a study in HIV-positive transwomen showed that their hormone therapy interacted with antiretroviral therapy in a way that could make it less effective.
  • Neurodiversity is more common in the LGBTQIA+ community than in cisgender heterosexual people. While older studies suggested that autism make people less sensitive to pain, recent studies suggest that autistic people actually experience pain at a higher intensity than the general population, are less able to adapt to the sensation, and are more likely to have higher levels of pain-related anxiety. These findings could have an impact on current study outcomes, and also how we read older studies.
 
Access to clinical trials
People in the LGBTQIA+ community are more likely to be unemployed, work part-time, or have a lower-paid job. This has an impact on whether they can afford to travel to clinical trial sites or take time off for clinic visits.
 
Neurodiversity comes with issues of sensory overload and difficulties in processing or remembering information, all of which make the unfamiliarity of a clinical trial site harder to navigate.
 
Binary inclusion/exclusion criteria can also reduce the ability of trans and non-binary people to take part in clinical trials. Some clinical trials also actively exclude gay men and lesbians.
 
Building better clinical trials
Making changes improve access for LGBTQIA+ people to clinical trials. One key change is queering the language. Talking about studies using the binary terms men and women can exclude trans, non-binary and intersex people. Changing the wording, for example from men to people with a prostate or from women to people with ovaries, isn’t about erasing men and women and the language associated with them, it’s about being specific and accurate with the language that we use. This will broaden the population of people who see that they are able to participate, and make the results more applicable to the general population.
 
As an example, contraception wording in informed consent forms is often tailored towards heterosexual cisgender couples:
Often used wording
Alternative inclusive wording
If you are female, sexually active with a man and can have children, you and your partner will have to use [add here list of allowed methods of birth control].
 
Male participant:
Receiving <study treatment> could have an effect on your sperm and could lead to an unknown risk for an unborn child. If your partner is planning to become pregnant during the trial, you cannot take part.
 
If you take part in the trial, you and your partner will have to use [sponsor specific: include here list of allowed methods of birth control] for preventing pregnancy.
 
You agree to commit to tell your female partner that you are taking part in this trial, and to tell her that there may be risk to an unborn child.
​If there’s a possibility for you to get pregnant, you and/or your partner will have to use [add here list of allowed methods of birth control] to prevent pregnancy.
 
Receiving <study treatment> could have an effect on a participant’s sperm and could lead to an unknown risk for an unborn child.
 
If you or your partner are planning to become pregnant during the trial, you cannot take part.
 
You agree to commit to tell your partner, if they can get pregnant, that you are taking part in this trial, and to tell them that there may be risk to an unborn child.
​Some studies do need exclusion criteria, for example if hormone treatments cause drug-drug interactions with the study drug. In this case, the protocol should be worded to exclude the treatments and not the groups of people.
 
Other changes, some of which are simple and low or no cost, could make major differences to the inclusivity of a study:
 
  • Build trust
  • Train staff on equality, diversity and accessibility, and make sure that they understand that discrimination will not be tolerated
  • Include LGBTQIA+ individuals and groups when designing clinical trials, including how to remove barriers and eliminate bias, and the best way to collect data on gender and sexuality
  • Ensure that people are reimbursed for travel or missed work
  • Ask about sex assigned at birth as well as gender identity, and allow participants to self-describe using their own terminology and language
  • Ensure that records are kept and that staff read them before clinic visits, to avoid explanations, outing and misgendering at future visits
  • Include appropriate gender options on forms, including free-text space where possible
  • Provide changing rooms and toilets with gender-neutral options
  • If overnight stays are required, provide single rooms rather than male/female dorms
  • Include pronouns on staff name badges, and ask for participant pronouns as standard procedure
  • Provide images or video as well as text instructions for access to the clinical trial location
  • Ensure that people are followed up and thanked
  • Seek and incorporate feedback from LGBTQIA+ people and trial participants
  • Support LGBTQIA+ staff as well as patients
 
By involving more LGBTQIA+ people in studies and making them welcome, companies developing new drugs can improve the diversity of their clinical trials and improve access to drugs for all.

Why Diverse Representation in Clinical Research Matters

19/3/2024

0 Comments

 
Randomised controlled trials (RCTs), where study participants are randomly allocated to an experimental group or a control group, became the 'gold standard' of clinical research in the mid-20th century. [1] RCTs have historically enrolled proportionally more white men than people from other groups, with the thinking, at least in part, being that the results could be extrapolated to all populations. Subsequent research, however, has shown that this is not the case, as underrepresented groups may have different responses to the disease or drug, based on social, cultural and other contexts. [2] Diversity in clinical trials, which is about so much more than differences in biology, is therefore an essential part of ensuring that everyone has equitable access to the most effective and safest approaches to treatment.
