PARP Inhibitors: A Game-Changer for Ovarian Cancer Treatment and Patient Care

Published Date : Aug 2023
Author : Shruti Gaikwad

Ovarian cancer is commonly referred to as the "silent killer," and it presents a serious threat to women's health.  According to the National Women's Health Network, ovarian cancer is considered deadly because it rarely shows symptoms in its early stage. Unfortunately, this means that the disease typically goes undetected until it has spread to the pelvis and abdomen, and it is too late to take any action. So, let's go deep into the examination of ovarian cancer detection and treatment to see how new innovations and technology are reshaping the business landscape.

Introduction to Disease:

Ovarian cancer is a malignant tumor of the ovary. It comes from the ovary itself or, more frequently, from nearby organs that communicate with it, including the fallopian tubes or the abdominal wall. Ovarian cancer develops when abnormal cells in the fallopian tubes or ovaries multiply and proliferate uncontrollably.

Treatment methods for ovarian cancer have made amazing improvements. The landscape of ovarian cancer therapy is changing to provide patients with more efficient and individualized alternatives, ranging from surgery and chemotherapy to targeted medicines like PARP inhibitors. This introduction to treatment innovations provides a foundation for assessing the wide range of dynamic treatments available to address this important health issue.

However, innovative therapy has come to light that is revolutionizing the field of ovarian cancer treatment. The use of PARP inhibitors (PARPi) is revolutionizing the treatment for this fatal condition, giving patients new hope and better results.

This blog investigates the science of PARP inhibitors and examines their mechanism, effect on patient care, and bright future in the fight against ovarian cancer.

Understanding PARP Inhibitors: A Breakthrough Mechanism

A newly developed category of drugs known as PARP inhibitors was developed to specifically target the enzyme poly-ADP ribose polymerase (PARP). In healthy cells, PARP is an essential component of DNA repair. However, the PARP pathway is highly utilized for DNA repair in cancer cells, particularly in those with certain genetic abnormalities like BRCA mutations.

On May 8, 2020, the FDA approved drugs like olaparib (Lynparza) with bevacizumab for the initial treatment of women with advanced ovarian cancer. The approval covers the use of bevacizumab (Avastin) and olaparib inhibitor in women whose tumors have decreased partially or completely during initial treatment with chemotherapy that contains a platinum medication. In addition, the treatment can be used to treat women who have certain genetic alterations.

By inhibiting the activity of these PARP enzymes, PARP inhibitors take advantage of this weakness and prevent cancer cells from correctly repairing their DNA. For patients with BRCA mutations who have ovarian cancer, PARP inhibitors represent a particularly promising therapy option.

The use of these inhibitors results in focused therapy with fewer adverse effects since they primarily target cancer cells while protecting healthy cells.

Impact on Patient Care: A Transformational Journey:

The use of PARP inhibitors in the treatment of ovarian cancer patients has significantly improved treatment outcomes:

PARP inhibitors have an important milestone toward individualized medicine in terms of treatment. Patients with particular genetic alterations, including BRCA mutations, can benefit from these targeted medicines.

  • Enhanced Efficacy:

    Clinical trials involving PARP inhibitors such as Niraparib (Zejula), Lynparza, and veliparib have shown significant benefits in the treatment of women with high-grade serous epithelial ovarian, fallopian tube, or primary peritoneal cancer, particularly those who carry BRCA mutations. These inhibitors have demonstrated improvements in response rates and an extension of the period during which the disease does not progress (known as progression-free survival) in patients with ovarian cancer.
  • Niraparib Maintenance Therapy:

    After initial treatment, PARP inhibitors are used as maintenance therapy to stop the return of the disease. This method offers a fresh way to handle the illness and helps extend times of remission. In new trials, an international trial called PRIMA, the PARP inhibitor Niraparib was evaluated as maintenance therapy for women with newly diagnosed ovarian cancer. The niraparib's producer, GlaxoSmithKline, sponsored the trial.
  • Combination Therapies:

    To further improve treatment outcomes, researchers are looking into the possibility of combining PARP inhibitors with other therapeutic modalities, including chemotherapy and immunotherapy.
  • Lesser Side Effects:

    When compared to conventional chemotherapy, PARP inhibitors typically have lower side effects, which improve patients' quality of life while undergoing treatment.

Prospects and Challenges:

Although the effect of PARP inhibitors on the treatment of ovarian cancer is obvious, difficulties and concerns still exist:

  • Genetic testing:

    To establish a patient's suitability for PARP inhibitor therapy, it is essential to identify those with relevant genetic mutations.
  • Resistance:

    Over time, some patients may get tolerant to PARP inhibitors. The goal of ongoing research is to identify the processes underlying resistance and create countermeasures.
  • Availability and Price:

    For fair patient care, it is crucial to guarantee that patients have access to these cutting-edge therapies while also addressing cost and affordability.
  • Research Needed:

    More study is required to determine the full potential of PARP inhibitors both alone and in combination with other therapies for various subtypes of ovarian cancer.

Bringing Hope for the Future:

Some of the prominent companies manufacturing PARP inhibitors for ovarian cancer include:

  1. AstraZeneca:

    They manufacture the PARP inhibitor Olaparib, marketed under the brand name Lynparza. Lynparza has been used to treat over 75,000 patients worldwide in 2022. Lynparza is developed independently by the companies in conjunction with their respective programmed death-ligand 1 (PD-L1) and programmed cell death protein 1 (PD-1) drugs. Lynparza is the foundation of AstraZeneca's industry-leading portfolio of potential new medicines targeting DDR mechanisms in cancer cells.
  2. GlaxoSmithKline (GSK):

    GSK manufactures the PARP inhibitor Niraparib, marketed under the brand name Zejula.
  3. Pfizer:

    Pfizer manufactures the PARP inhibitor Talazoparib, marketed under the brand name Talzenna.
  4. Clovis Oncology:

    The company manufactures the PARP inhibitor Rucaparib, marketed under the brand name Rubraca.

In the world of ovarian cancer treatment, PARP inhibitors have become a ray of hope. Their individualized treatment plans, focused methodology, and favorable effect on patient care signal a turning point in the struggle against this powerful illness. The constant dedication of researchers, healthcare workers, and patients ensures that the way forward becomes clear with the promise of improved outcomes, enhanced quality of life, and reestablished hope for those affected by ovarian cancer as we navigate the difficulties and opportunities that lie ahead.
