InPACT

International penile advanced cancer trial  - an International Rare Cancers Initiative study

Disease site: Penile cancer, urological cancers

Treatment modalities: Combinations of surgery, neoadjuvant chemotherapy, neoadjuvant chemoradiotherapy and adjuvant chemoradiotherapy.

Status: Open to recruitment

Trial details

InPACT is an international phase III trial with a Bayesian design incorporating two sequential randomisations (InPACT-neoadjuvant and InPACT-pelvis) in patients with squamous carcinoma of the penis who have inguinal lymph node metastases (i.e. locally advanced disease). InPACT aims to determine:

  • If there is a role for neoadjuvant therapy in this patient group; and
  • If prophylactic pelvic lymph node dissection (PLND) improves survival in patients at high risk of recurrence following inguinal lymph node dissection (ILND).

400 patients will be recruited (200 from UK sites; 200 US & European sites) over a 5 year period. In randomisation 1 (InPACT-neoadjuvant), dependent on disease burden strata, patients are allocated to one of three initial treatment arms:

  • Standard surgery (ILND) – no neoadjuvant treatment;
  • Neoadjuvant chemotherapy followed by ILND; or
  • Neoadjuvant chemoradiotherapy followed by ILND.

In randomisation 2 (InPACT-pelvis), patients at high risk of relapse (based on histological interpretation of the ILND specimen) are randomised to either:

  • Prophylactic PLND; or
  • No prophylactic PLND (surveillance).

Patients in both arms will also receive adjuvant chemoradiotherapy, if not already received in the neoadjuvant setting.
