Scientists have discovered a new drug that works like a laser against primary bone cancer. The University of East Anglia has produced a novel medicine that is effective against all of the major kinds of primary bone cancer. Children are more likely to be affected by cancer that begins in the bones than by cancer that has spread to the bones.
The current treatment is arduous, including obsolete chemotherapy combinations and limb amputation. Despite this, the five-year survival rate is only 42%, owing partly to how quickly bone cancer spreads to the lungs.
A recent study published today, however, demonstrates how a novel medicine called ‘CADD522’ blocks a gene related to cancer spread in mice implanted with human bone cancer.
The new medicine boosts survival rates by 50% without requiring surgery or chemotherapy. And, unlike chemotherapy, it has no hazardous side effects such as hair loss, fatigue, or nausea.
Dr. Darrell Green of the University of East Anglia’s Norwich Medical School was inspired to examine pediatric bone cancer after his best friend died from the condition as a teenager. The team has now made what could be the most significant drug discovery in the sector in almost 45 years.
According to Dr. Darrell Green, Principal Researcher at the University of East Anglia’s Norwich Medical School, the kind of cancer that develops in the bones is known as primary bone cancer. It is the third most common solid childhood cancer after brain and kidney cancer. This is with around 52,000 new cases diagnosed each year worldwide.
The most concerning element of this type of cancer is its quick metastasis to other parts of the body. When cancer has spread, it is extremely difficult to treat with a curative aim.
Dr. Darrell Green’s Story
Ben Morley, my best buddy in high school, was diagnosed with primary bone cancer. His disease encouraged me to take action. This is because, during my studies, I discovered that this cancer has lagged far behind others in terms of research and therapeutic advancements. So I studied, went to university, and eventually got my PhD to study primary bone cancer.
I wanted to study the underlying biology of cancer spread so that we could intervene clinically. Also, to develop new treatments so that patients don’t have to go through what my friend Ben did.
Finally, we want to save lives and lessen the handicap caused by surgery. And now we have a new medicine that has the potential to accomplish just that.”
Drug Against Primary Bone Cancer: Participants in the Study
The researchers gathered bone and tumor samples from 19 patients at Birmingham’s Royal Orthopaedic Hospital. This tiny number, however, was more than adequate to detect some noticeable changes in the tumors.
The researchers utilized next-generation sequencing to discover different types of genetic regulators known as short RNAs as bone cancer progressed.
They also discovered that a gene called RUNX2 is activated in primary bone cancer. It is linked to the cancer’s spread. They went on to test a new medication called CADD522. This is a tiny chemical that prevents the RUNX2 protein from acting, in mice.
“In preclinical testing, metastasis-free survival was boosted by 50% with the new CADD522 medication on its own, without chemotherapy or surgery,” Dr Green added. “I’m hopeful that when paired with other treatments, like surgery, this survival rate will rise even higher.”
“Importantly, because the RUNX2 gene is not normally required by normal cells, the medicine doesn’t induce adverse effects like chemotherapy.”
“This breakthrough is really important because bone cancer treatment hasn’t changed for more than 45 years.
“The novel medicine that we’ve discovered is effective in all of the major bone cancer subtypes, and so far, our experiments suggest that it’s not hazardous to the rest of the body,” says Dr. Xu. This means that it would be a much gentler treatment for children with bone cancer than the current arduous chemotherapy and life-changing limb amputation.
“We hope it saves many lives,” he continued.
The medicine is currently being subjected to official toxicological testing. This is before the team gathers all of the data and approaches the MHRA for clearance to begin a human clinical study.
Areas primary Bone Cancer Affect
Primary bone cancer is an uncommon form of cancer that develops in bone tissue. Secondary bone cancer, on the other hand, arises when cancer cells spread (metastasize) to the bone from another part of the body. Primary bone cancer can affect any bone in the body, but the long bones of the arms and legs, the spine, and the pelvis are the most usually affected.
Osteosarcoma, chondrosarcoma, Ewing sarcoma, and malignant fibrous histiocytoma are all examples of primary bone cancer. The specific etiology of primary bone cancer is unknown, however, it may be linked to hereditary factors, radiation or chemical exposure, or past chemotherapy treatment.
Pain in the affected bone, swelling and soreness in the surrounding tissue, and fractures or weakness in the bone are all symptoms of primary bone cancer.

Treatment Options for Primary Bone Cancer
Depending on the kind and stage of the cancer, treatment options for primary bone cancer may include surgery, chemotherapy, radiation therapy, and targeted therapy.
Surgery is the most often used treatment for primary bone cancer. To prevent the cancer from spreading, the malignant tissue and some surrounding healthy tissue are removed.
The type of surgery used is determined by the location and degree of the cancer. In the case of osteosarcoma (a common type of primary bone cancer), for example, surgery may entail removing the diseased bone and replacing it with an artificial bone or metal implant.
Radiation treatment is the use of high-energy radiation beams to eliminate cancer cells. It can be used before or after surgery, or as the primary therapeutic option if surgery is not an option. In cases where the disease has progressed to other parts of the body, radiation therapy may be utilized to reduce discomfort and manage symptoms.
Chemotherapy includes the use of chemicals to kill cancer cells. It is commonly given intravenously or orally. Chemotherapy is frequently used in conjunction with surgery and/or radiation therapy to improve therapeutic efficacy.
Targeted therapy involves utilizing medications that specifically target cancer cells while leaving healthy cells alone. When the cancer has spread or has not responded to other therapies, this sort of therapy may be employed.
Immunotherapy involves the use of medications that assist the immune system in recognizing and attacking cancer cells. It can be used in conjunction with other treatments or as a stand-alone therapy.
However, with this new discovery, the age of primary bone cancer ravaging the masses is nearly behind us.
