Durable response to an anti-CD25 antibody-drug conjugate and anti-PD-1 antibody in ovarian carcinoma: a case report

Although PD-1 checkpoint inhibition has improved outcomes for some cancer types, a substantial proportion of solid tumors still do not respond, in part due to inadequate cytotoxic CD8+ T-cell infiltration and survival within the tumor microenvironment (TME). CD25+ regulatory T-cells (Tregs) are a subset of T-cells that play a key role in suppressing CD8+ T-cell activity. Depletion of Tregs in the TME could thus enhance anti-cancer immune responses. Here, we present the experience of a patient with platinum-resistant ovarian carcinoma who achieved a durable partial response on a phase 1 clinical trial of an anti-CD25 antibody-drug conjugate combined with pembrolizumab. Notably, her tumor response correlated with a reduction in CD25+ Tregs on paired tumor biopsies and further deepened after treatment discontinuation. This case provides early proof-of-concept that Treg depletion combined with PD-1/PD-L1 inhibitors can lead to anti-cancer efficacy in refractory diseases and offers key lessons to guide future development of anti-Treg therapeutics.

Nivolumab induced discolouration of the tongue: a case report

Currently, immune checkpoint inhibitors are used in the treatment of ovarian cancer. Immunotherapy agents occasionally cause the development of skin reactions characterized by mild erythematous and maculopapular rashes, usually involving the trunk and extremities of the body, which may occasionally present with pruritus. It is especially seen in the use of anti-PD-1 (nivolumab and pembrolizumab) treatment agents. In this case report, we present a patient who developed discoloration of the tongue toxicity after nivolumab treatment in ovarian cancer patients. Discoloration of the tongue, which is one of the rare side effects of immunotherapy, and factors that may be associated with it are discussed in this case.

Penpulimab and Anlotinib in an Elderly Patient with Recurrent Cervical Cancer: A Case Report and Literature Review

We present a case of a 76-year-old patient with recurrent cervical cancer who underwent first-line treatment with penpulimab combined with anlotinib. The patient was diagnosed with poorly differentiated stage III C1r cervical squamous cell carcinoma and received standard cisplatin-sensitized chemoradiotherapy, subsequently achieving a good treatment effect of complete response. Recurrence occurred nearly 14 months after treatment, with multiple metastases including in the brain and lung. Oral anlotinib was less effective, but the treatment of penpulimab combined with anlotinib showed an obvious curative effect. It has been maintained for more than 17 months, and as of April 2023 the patient is still maintaining her response. Our case suggests that penpulimab combined with anlotinib has promising efficacy in the treatment of elderly patients with recurrent cervical cancer.
