Updates From a PARP Inhibitor Clinical Trial for Patients with Metastatic Pancreatic Cancer


A subset of patients with metastatic pancreatic cancer and an inherited BRCA mutation rapidly progressed during a clinical trial of Lynparza.

In the phase 3 POLO trial looking at Lynparza (olaparib), a PARP inhibitor, as maintenance therapy for patients with metastatic pancreatic cancer and an inherited BRCA mutation, researchers weren’t able to identify the clinical characteristics of patients whose cancer rapidly progressed, according to Dr. Teresa Macarulla.

At the start of the trial, there were already patients with more advanced cancer compared with other patients, and through the course of the study the patients with advanced disease didn’t benefit as well as the rest of the trial participants.

During the annual American Society of Clinical Oncology Gastrointestinal Cancers symposium, Macarulla, a gastrointestinal oncologist at the Vall d’Hebron Institute of Oncology in Barcelona, Spain, presented updated study findings and also spoke with CURE® about patient outcomes.


There's a percentage of patients that are included in the POLO trial that progress rapidly. We define this population as those patients that progress within the first four months of the randomization after the organization, so in the second CT scan.

Unfortunately, we see that the numbers are not so high, because the number of the total population of the trial is not so high, and it’s difficult to define the clinical characteristics of the patients in this group. It is true that those patients at the beginning presented worse general status or worse performing status. In that, are those patients that it seems that are more likely to be rapid progressors, but we cannot identify more than this.

For patients with cancer, the ongoing chemotherapy shortage may cause some anxiety as they wonder how they will receive their drugs. However, measuring drugs “down to the minutiae of the milligrams” helped patients receive the drugs they needed, said Alison Tray. Tray is an advanced oncology certified nurse practitioner and current vice president of ambulatory operations at Rutgers Cancer Institute in New Jersey.  If patients are concerned about getting their cancer drugs, Tray noted that having “an open conversation” between patients and providers is key.  “As a provider and a nurse myself, having that conversation, that reassurance and sharing the information is a two-way conversation,” she said. “So just knowing that we're taking care of you, we're going to make sure that you receive the care that you need is the key takeaway.” In June 2023, many patients were unable to receive certain chemotherapy drugs, such as carboplatin and cisplatin because of an ongoing shortage. By October 2023, experts saw an improvement, although the “ongoing crisis” remained.

Transcript: Particularly at Hartford HealthCare, when we established this infrastructure, our goal was to make sure that every patient would get the treatment that they need and require, utilizing the data that we have from ASCO guidelines to ensure that we're getting the optimal high-quality standard of care in a timely fashion that we didn't have to delay therapies. So, we were able to do that by going down to the minutiae of the milligrams on hand, particularly when we had a lot of critical drug shortages. So it was really creating that process to really ensure that every patient would get the treatment that they needed.
