Repurposing Infectious Diseases Vaccines Against Cancer

Vaccines used to prevent infections have long been known to stimulate immune responses to cancer as illustrated by the approval of the Bacillus Calmette–Guérin (BCG) vaccine to treat bladder cancer since the 1970s. The recent approval of immunotherapies has rejuvenated this research area with reports of anti-tumor responses with existing infectious diseases vaccines used as such, either alone or in combination with immune checkpoint inhibitors. Here, we have reviewed and summarized research activities using approved vaccines to treat cancer. Data supporting a cancer therapeutic use was found for 16 vaccines. For 10 (BCG, diphtheria, tetanus, human papillomavirus, influenza, measles, pneumococcus, smallpox, typhoid and varicella-zoster), clinical trials have been conducted or are ongoing. Within the remaining 6, preclinical evidence supports further evaluation of the rotavirus, yellow fever and pertussis vaccine in carefully designed clinical trials. The mechanistic evidence for the cholera vaccine, combined with the observational data in colorectal cancer, is also supportive of clinical translation. There is limited data for the hepatitis B and mumps vaccine (without measles vaccine). Four findings are worth highlighting: the superiority of intravesical typhoid vaccine instillations over BCG in a preclinical bladder cancer model, which is now the subject of a phase I trial; the perioperative use of the influenza vaccine to limit and prevent the natural killer cell dysfunction induced by cancer surgery; objective responses following intratumoral injections of measles vaccine in cutaneous T-cell lymphoma; objective responses induced by human papillomavirus vaccine in cutaneous squamous cell carcinoma. All vaccines are intended to induce or improve an anti-tumor (immune) response. In addition to the biological and immunological mechanisms that vary between vaccines, the mode of administration and sequence with other (immuno-)therapies warrant more attention in future research.

“…Indeed, using an identical vaccination protocol, we previously treated a patient with exceedingly high AK burden (>1,000 AKs), noting marked reduction in lesion number and improved skin texture over 1 year [ 6 ]. Interestingly, systemic and intratumoral use of HPV vaccines were recently described in the context of KC for 4 immunocompetent and 1 immunocompromised patient [ 7 , 8 , 9 , 10 ]. In comparison with KCs, an accelerated response seemed to occur in precursor AKs.…”

Off-Label 9-Valent Human Papillomavirus Vaccination for Actinic Keratosis: A Case Series

et al. 2021

Background: The suspected link between human papillomavirus (HPV) and the development of premalignant and malignant skin lesions remains inadequately examined in clinical settings. This case series describes HPV vaccination as an off-label adjuvant therapy for actinic keratosis (AK). Methods: Twelve immunocompetent AK patients underwent HPV vaccination at a private dermatology clinic in Naestved, Denmark. Prior to vaccination, all patients demonstrated a high AK burden that required regular control visits. At 0, 2, and 6 months, the patients received an intramuscular injection of a commercially available 9-valent HPV vaccine. Concurrently, patients continued conventional AK therapies at 3-month intervals. Clinical response, consisting of reduction in AK number and general change in skin appearance, was assessed by a dermatologist over 12 months following first vaccination. Results: All patients (mean age 76.2 years; 10 M and 2 F) completed the vaccine schedule. Overall, an average 85% reduction in total AK burden was recorded 12 months after beginning vaccination. Median AK burden thus fell from 56 (IQR: 44–80) to 13.5 (IQR: 1–18) lesions after 12 months. Lesion reduction was observable by the second inoculation at month 2 (34 AKs; IQR 22–80), continuing steadily until month 6 (15 AKs; IQR 5–30) and plateauing between 6 and 12 months. Clinically, HPV vaccination elicited fading of lesions’ erythematous background after the first dose, often followed by sloughing of hyperkeratotic elements in subsequent weeks. Patients reported no adverse effects related to HPV vaccination. Conclusion: This case series introduces the possibility that 9-valent HPV vaccination in combination with conventional treatments may be used as a therapeutic strategy for AK.

“…5,6 Recently, it has been reported successful use of the human papilloma virus (HPV) vaccine for the treatment of multiple cutaneous malignancies. 7 It should be noted that despite considerable advances in developing fairly effective and safer cancer vaccines like dendritic cell (DC) vaccine, 8 chimeric antigen receptor (CAR) T-cell, 9 human telomerase reverse transcriptase (hTERT) derived vaccines, 10 deoxyribonucleic acid (DNA) vaccines, 11 neoantigen vaccines, 12 the clinical translation of cancer vaccines into clinically effective therapies has been quite challenging. 13 Today, technological advances accelerated by the coronavirus disease-2019 (COVID-19) pandemic led to the emerging application of messenger ribonucleic acid (mRNA) technology in developing vaccines.…”
