Cleveland Clinic To Begin Clinical Trials For The First-of-Its-Kind Breast Cancer Vaccine

Human Trials For The Novel Triple-Negative Breast Cancer Vaccine Is Set To Begin

A vaccine for the most deadly and aggressive kind of breast cancer is one step closer to reality.

On 26th October, the Cleaveland Clinic declared that it is embarking on a first-of-its-kind human trial for a vaccine tailored to protect from TNBC (Triple-Negative Breast Cancer). This condition can only be prevented with surgical removal of breasts, also known as mastectomy. Targeted hormone treatments do not work in this case.

So far, advancements in the development of vaccines for TNBC have been restricted to animal research and laboratory experiments. Since the US FDA (Food & Drug Administration) authorized the IND (Investigational New Drug) Application for the vaccine, human trials will be commencing shortly.

As the human trial will just comprise initial-stage TNBC survivors who are vulnerable to recurrence, the scientists aspire to subsequently administer the shots to healthy individuals who are vulnerable to the disease condition, such as those with mutations in the BRCA1 gene.

Principal Investigatory of the project and representative of Taussig Cancer Institute, Cleveland Clinic, Dr. Thomas Budd stated in a press release that they are expecting this vaccine to be a stable and true prophylactic vaccine, which can be used in healthy women to prevent TNBC, which is a kind of breast cancer that has the least effective therapies.

Human Trial Participants Will Get Three Doses

TNBC accounts for 12-15% of all breast cancers and kills almost one-fourth of women 5 years after diagnosis. TNBC is prevalent in Afro-American women with mutations in the BRCA1 gene.

The presence of a particular protein known as α-lactalbumin generally is a part of the disease, although it is supposed to produce when the individual is lactating.

The shot will target this protein, triggering the immune system to prevent the development of tumors in the breast. Additionally, the vaccine includes a drug that warns the immune system about the presence of α-lactalbumin, such that it can obstruct any tumor growth.

The human trial will comprise 18-24 individuals, who are cancer-free following the treatment for initial-stage TNBC within the last 3 years. There will be a total of 3 vaccines used, each of these shots will be administered 2 weeks apart. Scientists will begin with low doses in a couple of individuals and closely observe them prior to increasing the dosage and including more individuals for the study.

Budd reported to the Cleveland Clinic that after determining the optimal dosage to be administered, they will study the effects of the vaccine on the immune system. This will help them understand whether the vaccine is effective as expected and later, they will increase the level of dose.

The research is expected to be completed by the month of September 2022. The US Department of Defense supports the project financially.

Tuohy added that this preventative breast cancer vaccine has the competence to be used for other kinds of tumors.

Their translational research program concentrates on producing vaccines that protect humans against age-associated diseases such as endometrial, ovarian, and breast cancer. If it is effective, these vaccines have the capacity to boost life expectancy in a way like the effect induced by the childhood vaccination program and revolutionize the way adult-onset cancers are controlled.
