Trial Summary

Will I have to stop taking my current medications?

The trial does not specify if you need to stop all current medications, but you must be on adjuvant endocrine therapy and cannot use tamoxifen if you are in the hydroxychloroquine group. If you are on tamoxifen, you may need to switch to an aromatase inhibitor at least 21 days before starting the trial. You can continue bone-modifying agents if you are already taking them.

What data supports the effectiveness of the drug combination Avelumab, Palbociclib, and Hydroxychloroquine for breast cancer?

Avelumab, a PD-L1 inhibitor, has shown antitumor activity in metastatic breast cancer, and Palbociclib has improved progression-free survival in advanced breast cancer when combined with other treatments. These findings suggest potential effectiveness when these drugs are used together for breast cancer.12345

Is the combination of Avelumab, Palbociclib, and Hydroxychloroquine safe for humans?

Avelumab has been studied for safety in various cancers, including breast cancer, and is generally considered safe, but it can have side effects like hepatitis (liver inflammation), nephritis (kidney inflammation), and dermatitis (skin inflammation). Palbociclib and Hydroxychloroquine are also used in cancer treatments and have known safety profiles, but combining them with Avelumab may have unique risks that should be discussed with a healthcare provider.12678

What makes the drug combination of Avelumab and Palbociclib/Hydroxychloroquine unique for breast cancer treatment?

This treatment is unique because it combines Avelumab, an immune checkpoint inhibitor that helps the immune system attack cancer cells, with Palbociclib, a drug that stops cancer cells from dividing, and Hydroxychloroquine, which may enhance the effectiveness of cancer treatments. This combination targets cancer in multiple ways, which is different from standard treatments that usually focus on one mechanism.49101112

What is the purpose of this trial?

This clinical trial will assess the safety and early efficacy of Hydroxychloroquine or Avelumab, with or without Palbociclib, in early-stage ER+ breast cancer patients who are found to harbor disseminated tumor cells (DTCs) in the bone marrow after definitive surgery and standard adjuvant therapy.

Eligibility Criteria

This trial is for adults over 18 with early-stage ER+ breast cancer, who've completed primary and adjuvant therapy (except endocrine therapy), have no recurrent disease, and DTCs detected in bone marrow. They must not have had another invasive breast cancer or severe medical conditions like uncontrolled heart disease, lung dysfunction, or liver disease.

Inclusion Criteria

I don't have any health conditions that would prevent me from taking the study drugs.
I have finished all initial cancer treatments and any side effects are mild, except for hair loss or nerve issues.
I had stage II-III breast cancer that was ER+ and Her2-, treated with the goal of cure, and currently show no signs of the cancer returning.

Treatment Details

Interventions

  • Avelumab
  • HCQ
  • Palbociclib
Trial Overview The trial tests the safety and efficacy of Hydroxychloroquine (HCQ) or Avelumab with/without Palbociclib on patients with dormant breast cancer cells post-surgery. It aims to see if these treatments can eliminate disseminated tumor cells in the bone marrow.

Findings from Research

In a phase 1 trial involving 168 patients with metastatic breast cancer (MBC), avelumab, a PD-L1 inhibitor, demonstrated an overall objective response rate of 3.0%, with a higher response rate of 5.2% in patients with triple-negative breast cancer (TNBC).
The study found that patients with PD-L1 positive tumor-associated immune cells had a significantly higher response rate to avelumab (16.7%) compared to those with PD-L1 negative cells (1.6%), suggesting that PD-L1 expression may help predict treatment efficacy.

The JAVELIN Ovarian 200 trial is the first Phase III study to investigate the effectiveness of avelumab, a PD-L1 checkpoint inhibitor, in treating women with platinum-resistant ovarian cancer, involving multiple treatment arms to assess its efficacy.
The trial will measure overall survival and progression-free survival as primary outcomes, providing valuable insights into the potential benefits of avelumab alone or in combination with doxorubicin compared to doxorubicin alone.

The combination of durvalumab (a PD-L1 inhibitor) and olaparib (a PARP inhibitor) with standard paclitaxel chemotherapy significantly increased pathologic complete response (pCR) rates in stage II/III HER2-negative breast cancer, with rates rising from 20% to 37% overall.
While DOP showed enhanced efficacy, particularly in high-risk hormone receptor-positive/HER2-negative patients (pCR 64% vs. 22%), it also resulted in a higher incidence of immune-related grade 3 adverse events (12.3% vs. 1.3% in the control group).
