Patients will be registered prior to, during or at the completion of neoadjuvant chemotherapy
(Paclitaxel 175 mg/m2 IV over 3 hours and Carboplatin AUC 6 IV on Day 1 every 21 days for 3-4
cycles). Registered patients who progress during neoadjuvant chemotherapy will not be
eligible for iCRS and will be removed from the study.

Following completion of neoadjuvant chemotherapy, interval cytoreductive surgery (iCRS) will
be performed in the usual fashion in both arms. Patients will be randomized at the time of
iCRS (iCRS must achieve no gross residual disease or no disease >1.0 cm in largest diameter)
to receive HIPEC or no HIPEC. Patients randomized to HIPEC (Arm A) will receive a single dose
of cisplatin (100mg/m2 IP over 90 minutes at 42 C) as HIPEC. After postoperative recovery
patients will receive standard post-operative platinum-based combination chemotherapy.
Patients randomized to surgery only (Arm B) will receive postoperative standard chemotherapy
after recovery from surgery.

Both groups will receive an additional 2-3 cycles of platinum-based combination chemotherapy
per institutional standard (Paclitaxel 175 mg/m2 IV over 3 hours and Carboplatin AUC 6 IV on
Day 1 every 21 days for 2-3 cycles) for a maximum total of 6 cycles of chemotherapy
(neoadjuvant plus post-operative cycles) followed by niraparib individualized dosing until
progression or 36 months (if no evidence of disease).

The purpose of this study is to assess the safety, tolerability, and recommended dose(s) of
BMS-986340 as monotherapy and in combination with nivolumab or docetaxel in participants with
advanced solid tumors. This study is a first-in-human (FIH) study of BMS-986340 in
participants with advanced solid tumors.

This phase III trial studies how well active surveillance help doctors to monitor subjects with low risk germ cell tumors for recurrence after their tumor is removed. When the germ cell tumors has spread outside of the organ in which it developed, it is considered metastatic. Drugs used in chemotherapy, such as bleomycin, carboplatin, etoposide, and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. The trial studies whether carboplatin or cisplatin is the preferred chemotherapy to use in treating metastatic standard risk germ cell tumors.
