The battle against cancer has witnessed significant strides in recent years, with the advent of innovative treatment modalities like immunotherapy and targeted therapy. Among these promising approaches, alpha emitter therapy has emerged as a beacon of hope, offering a unique and potentially transformative approach to cancer treatment.
Alpha emitters are radioactive isotopes that emit high-energy alpha particles, which possess remarkable destructive power against cancer cells. Unlike conventional radiation therapy, where the radiation dose is distributed more widely, alpha emitters selectively target and annihilate cancer cells with minimal damage to surrounding healthy tissues. This unique characteristic stems from the short range of alpha particles, ensuring that their destructive power is concentrated within the confines of the tumor.

Alpha decay, also known as -decay, is a kind of radioactive decay in which an atomic nucleus produces an alpha particle (helium nucleus) and therefore converts or decays into a new atomic nucleus with a mass number of four and an atomic number of two. An alpha particle is the same as a helium-4 atom’s nucleus, which is made up of two protons and two neutrons. It has a mass of 4 u and a charge of +2 e.
While alpha particles have a charge of +2 e, this is rarely displayed since a nuclear equation explains a nuclear reaction without taking electrons into account – a practice that does not imply that nuclei always occur in neutral atoms.
The most frequent type of cluster decay is alpha decay, in which the parent atom ejects a defined daughter collection of nucleons, leaving another determined product behind. It is the most prevalent type due to the alpha particle’s extraordinarily high nuclear binding energy and comparatively modest mass.
Alpha decay, like other cluster decays, is basically a quantum tunneling phenomenon. In contrast to beta decay, it is regulated by the interaction of the strong nuclear force and the electromagnetic force.Radium-223 is an alpha emitter that is naturally attracted to bone due to its calcium mimetic properties.
Radium-223 can be pumped into a cancer patient’s veins, where it migrates to areas of the bone with high cell turnover due to the presence of metastasized tumors.
Ra-223 emits alpha radiation once within the bone, which can kill tumor cells within a 100-micron radius. Radium-223 dichloride, also known as Xofigo, is a medication that has been used to treat prostate cancer that has spread to the bone.
Radionuclides injected into the circulation can reach places accessible via blood arteries. This indicates that radiation may not successfully destroy the interior of a huge tumor that is poorly vascularized (i.e., not well penetrated by blood vessels).
The -particle, a bare 4He nucleus with a +2 charge, travels along a nearly linear path because of its enormous mass in comparison to electrons. With an initial kinetic energy of between MeV, alpha particles are monoenergetic and produce a matching particle ring. Alpha particles, which are categorised as having a high LET, are efficient ionising agents.
Target uptake, dosimetry, and therapy response are frequently measured using the photons, distinctive X-rays, or bremsstrahlung radiation that follows the parent radionuclide’s decay because -particles cannot be directly observed in vivo.
There have also been reported indirect radiation effects in addition to direct ones. The impact of -radiation is also influenced by the radiation-induced bystander effect, which is when DNA damage develops in cells that are near irradiated cells but are not directly exposed to radiation.
The global alpha emitter market is projected to reach USD 3,833.3 million by 2030, from USD 569.6 million in 2022, at a CAGR of 16.4%.
The global alpha emitter market is witnessing significant technological advancements that are enhancing the efficacy, safety, and applicability of alpha emitter therapy. These advancements hold immense promise for revolutionizing cancer treatment and potentially extending the reach of alpha-emitter therapy to other diseases.
Development of Novel Alpha Emitters with Enhanced Properties Researchers are continuously developing new alpha emitters with enhanced properties, such as longer half-lives, improved targeting capabilities, and reduced systemic toxicity. These advancements are addressing key limitations of existing alpha emitters, such as short half-lives that necessitate frequent administration and limited targeting specificity that can cause unwanted side effects.
Example: Actinium-225 (Ac-225) is a promising alpha emitter with a longer half-life than radium-223, a commonly used alpha emitter. This longer half-life allows for less frequent administration of Ac-225, reducing the patient’s exposure to radiation and potentially improving treatment compliance.
Targeted alpha therapy utilizes molecules to deliver alpha particles directly to cancer cells, minimizing damage to surrounding healthy tissues. This approach significantly enhances the therapeutic efficacy and reduces side effects compared to conventional radiation therapy, where the radiation dose is distributed more widely.
Example: Targeted alpha therapy using antibodies conjugated to alpha emitters is a promising approach. The antibodies bind specifically to cancer cells, delivering the alpha particles directly to the tumor site with minimal impact on healthy tissues.
Researchers are developing innovative delivery systems for alpha emitters, such as nanoparticles or targeted carriers. These delivery systems aim to overcome the challenges of conventional alpha emitter administration, such as limited stability and poor targeting specificity.
Example: Nanoparticles coated with tumor-targeting molecules can encapsulate alpha emitters and deliver them directly to cancer cells, enhancing therapeutic efficacy while minimizing systemic exposure to radiation.
Companion Diagnostics for Patient Selection
Companion diagnostics are being developed to identify patients most likely to benefit from alpha emitter therapy. These diagnostics can help select patients with the optimal molecular characteristics to ensure that the therapy is used effectively and efficiently.
Example: Biomarker-based companion diagnostics can identify patients with specific genetic mutations or protein expression patterns that are associated with improved response to alpha emitter therapy.
Research is exploring the potential of alpha emitter therapy for treating non-cancerous diseases, such as arthritis and neurodegenerative disorders. The unique properties of alpha emitters, such as their ability to target specific cells and destroy them without causing significant damage to surrounding tissues, hold promise for treating these diseases.
Example: Alpha emitter therapy is being investigated for the treatment of rheumatoid arthritis, where alpha particles could target and destroy inflammatory cells responsible for joint damage. These technological advancements are paving the way for a new era in alpha emitter therapy, offering hope for more effective and targeted cancer treatment and expanding the potential applications of this innovative approach to medicine.
