Breakthroughs in drugs are thrilling. They pledge to mitigate global human suffering, addressing pressing issues on an international scale. Despite the time-consuming process that often spans several years, it’s only after rigorous testing and evaluation that innovative medicines and therapies make their way from the lab to your local pharmacy. As people journey through life, they will inevitably encounter unexpected challenges and setbacks at some point. Before obtaining approval, scientific trials, which rigorously test treatments for both safety and effectiveness, serve as the final barrier.
The past year has been replete with significant advancements in scientific research, as evidenced by a plethora of groundbreaking studies and clinical trial outcomes.
Despite the commotion surrounding blockbuster drugs Ozempic and Wegovy, they still commanded widespread attention. While acknowledged for their impact on weight loss, that’s just the beginning. According to studies, a medication has shown significant promise in treating over 1.6 million individuals suffering from obesity-related health issues, effectively reducing the risk of developing ten types of associated cancers, including those affecting the liver, kidneys, pancreas, and skin. Another study spanning 12 months found that a similar type of medication showed promise for individuals with mild Alzheimer’s disease.
Meanwhile, researchers investigated the potential of psychedelics, including MDMA, in addressing post-traumatic stress disorder (PSTSD). The year-long delay posed an unexpected hurdle to the burgeoning psychedelic renaissance, as the FDA’s rejection of several key initiatives sparked concerns about the sector’s future. As interest in its therapeutic capabilities persists, the subject remains increasingly recognized for its potential to positively impact mental health and well-being.
There’s lenacapavir, a shot that provides long-term protection against HIV infection for individuals at risk. Dubbed “Sisters for a Cure”, this initiative comprehensively safeguarded African adolescent females against HIV transmission. Another trial corroborated these findings, demonstrating that the medication showed nearly 100% effectiveness in protecting individuals who engage in sexual intercourse with males. The breakthrough’s foundation lies in a novel comprehension of the protein “capsule” shielding the virus’ genetic material. Numerous viruses share a common blueprint, suggesting that this approach could also aid researchers in developing effective treatments for multiple viral strains simultaneously.
What medical advancements are poised to transition from promising findings to real-world applications by 2025? In the coming year, several key developments and trends are likely to shape the future landscape.
Researchers Take Aim at Cure for Sickle Cell Disease with Gene Editing.
Base editing is a type of gene editor, akin to the versatile genetic tool CRISPR-Cas9. Based on innovative technology developed in 2016, the Base Enhancing method targets a single DNA strand at a time, minimizing the risk of collateral damage to non-targeted genomic components by not cutting each strand.
In the past, researchers combined base editing with CAR T-cell therapy to eradicate cancer cells effectively. Led by Beam Therapeutics, researchers successfully edited four genes in immune cells to significantly enhance their ability to target and destroy cancer cells. Researchers recently launched an investigation into the potential of base-edited blood stem cells to treat severe sickle cell disease, with early results expected in February 2025 for this debilitating condition.
In sickle cell disease, a genetic mutation alters the shape of red blood cells, transforming them from their typical doughnut-like form to crescent-shaped cells with pointed ends. The illness progressively damages blood vessels, leading to chronic pain.
Researchers in the BEACON trial modify hematopoietic stem cells (HSCs) to correct faulty genetic information by editing blood stem cells. These stem cells develop into all of our blood cells, including those responsible for immunity, playing a crucial role in treating blood-related illnesses.
The BEACON trial design is open-label and single-arm, indicating that all participants receive the treatment, and as it is an open-label study, they typically are aware of their assigned therapy. During the trial, hematopoietic stem cells (HSCs) are harvested from each participant and engineered to express an enhanced fetal hemoglobin gene, which boosts the production of hemoglobin – a vital protein responsible for transporting oxygen in red blood cells. Increasing levels of the protein are expected to amplify visible indicators.
The trial faces challenging headwinds from its early outcomes. Although the fatalities were attributed to unforeseen consequences of busulfan, a medication employed to induce space within the bone marrow prior to transplantation, rather than the bone marrow regenerating naturally. If successful, this trial could potentially pave the way for treating a range of inherited diseases, thereby advancing medical understanding and bringing it closer to practical applications.
Cancer’s Deadliest Foes: The Surprising Power of Radioactive Medicine?
Prostate most cancers creeps up. Despite the challenges, timely screening can often lead to early detection. Most cancer cells harbor a protein called PSMA, which has long been an attractive target for therapies seeking to combat this disease.
After more than a decade of rigorous analysis, one molecule emerged as the most promising candidate: lutetium-177. Initially approved for treating advanced prostate cancer, the medication significantly enhanced both survival rates and overall well-being.
Pluvicto has received FDA approval for use as a post-chemotherapy treatment. Is the ongoing trial exploring whether prompt intervention may lead to more successful results?
In excess of 1,100 patients with minimally treated prostate cancer that has progressed, the trial is evaluating early treatment options for a specific population of patients. Patients with advanced prostate cancer often undergo hormone therapy as part of their treatment regimen; however, this approach can also reduce their sensitivity to Pluvicto.
The novel therapy has the potential to revolutionize treatment options for hundreds of thousands of men worldwide, according to Dr. Oliver Sartor, leading the trial.
As cannabis becomes increasingly mainstream, researchers are uncovering unexpected links between THC consumption and psychosis. A recent study suggests that the psychoactive compound in weed may increase the risk of developing psychotic disorders.
As illicit substances, psychedelics’ resurgence remains shrouded in controversy despite gaining traction nationwide. While CBD, a non-psychoactive compound found in cannabis, is not typically associated with hallucinogenic effects, it can still produce similar outcomes. The FDA has approved hemp-derived CBD products for the treatment of seizures in children aged two and above.
A groundbreaking scientific study, dubbed “hope,” aims to utilize a novel molecule that may also prove beneficial for individuals afflicted with psychosis stemming from schizophrenia or other related disorders. Conducted primarily in the UK, the study comprises three placebo-controlled, double-blind, randomised clinical trials, widely regarded as the gold standard in medical research.
Prior to seeking approval, Section 3 research will comprehensively assess the effects of CBD, both with and without anti-psychotics, on individuals exhibiting diverse levels of psychosis.
Two distinct trials are being conducted: one focuses on individuals who have experienced a single episode, while the other targets those with a history of psychosis that is resistant to medication-based treatments. The final trial serves as a preventive measure, identifying individuals at high risk of developing psychosis and intervening early to prevent its onset. Utilizing a combination of blood assessments, standardized questionnaires, and neuroimaging techniques, the research team aims to rigorously evaluate how participants respond to CBD.
The study will be one of the largest to date on CBD, linking 30 websites across 11 countries and enrolling approximately 1,000 participants. The study will endeavour to identify biomarkers that could potentially forecast treatment efficacy. Researchers anticipate counting will conclude by 2025, hoping that the trial will illuminate the potential therapeutic effects of CBD on severe psychiatric disorders.
Are Personalized Breast Cancer Screenings on the Horizon?
Breast cancer is alarmingly prevalent. Screening tips are often generic and fail to account for individual circumstances. Typically, such milestones are predicated primarily on an individual’s age, typically commencing around the 50-year mark in many countries. Despite their limitations, the assessments have shown modest success in reducing the risk of mortality by just 20%.
The lingering impact on a part of this is due to a household’s entrenched history. Each person’s unique risk profile stems from a combination of genetic predispositions, lifestyle choices, and varied environmental factors. For individuals at low risk, mammograms may not be necessary even if they meet the recommended screening guidelines. Meanwhile, for girls at high risk, more rigorous screening may better detect cancerous cells.
A pioneering trial is endeavouring to personalise breast cancer screening by tailoring the approach to individualised risk profiles. To date, the largest-scale international study has commenced operationally across six global sites, enrolling more than 53,000 women. The impact on wellbeing outcomes will be assessed for women who adhere to standard breast cancer screening guidelines and those who participate in personalized screenings.
The group will leverage its collective understanding of genetics to assess risk factors, combining this expertise with other key elements, such as family history and breast density, to develop a personalized remedy. Researchers will track the women’s health and determine whether any of them develop breast cancer approximately four years following the initial study. If financially viable, this approach could effectively support those at high risk while minimizing unnecessary harm and streamlining screenings for individuals with low risk.
