Clinical Trial Summary

In this study, Genocea is evaluating an investigational, personalized adjuvanted vaccine, GEN-009, that is being developed for the treatment of patients with solid tumors. A proprietary tool developed by Genocea, called ATLAS™ (Antigen Lead Acquisition System) will be used to identify neoantigens in each patient's tumor that are recognized by their CD4 and/or CD8 T cells. ATLAS-identified neoantigens will then be incorporated into a patient's personalized vaccine in the form of synthetic long peptides (SLPs).

Description:

This first-in-human study of GEN-009 will be conducted in two parts in adult patients with cutaneous melanoma, non-small cell lung cancer (NSCLC), squamous cell carcinoma of the head and neck (SCCHN), urothelial carcinoma, or renal cell carcinoma (Part B only). In Part A, the safety and immunogenicity of single-agent GEN-009 will be evaluated in patients with the above-noted tumor types who have completed treatment with curative intent for their disease (eg, surgical resection, neoadjuvant and/or adjuvant chemotherapy, and/or radiation therapy) and have no evidence of disease (NED) at the time of initiating vaccination with GEN-009. In Part B, up to 15 patients in each disease cohort will be enrolled and evaluated for safety, immunogenicity, and preliminary antitumor activity of GEN-009. Patients in Part B will receive GEN-009 at the schedule selected in Part A, in combination with a PD-1 inhibitor therapy (nivolumab or pembrolizumab) at the approved dose and schedule per the United States Package Insert (USPI). In addition, up to 15 patients who enroll in one of the Part B disease-specific cohorts but whose disease progresses during the screening period therapy may be enrolled into a separate relapsed/refractory disease cohort.

listed below:

1. NSCLC: Patients with metastatic non-squamous NSCLC beginning first-line pembrolizumab in combination with pemetrexed and platinum chemotherapy, or metastatic squamous NSCLC beginning first-line pembrolizumab in combination with carboplatin and either paclitaxel or nab-paclitaxel

2. SCCHN: Patients beginning pembrolizumab with recurrent or metastatic SCCHN with disease progression on or after a platinum-based therapy, or beginning first-line pembrolizumab for recurrent or metastatic SCCHN if tumors express PD-L1 with a Combined Positive Score (CPS) = 1.

3. Cutaneous Melanoma: Patients with unresectable or metastatic cutaneous melanoma beginning nivolumab monotherapy or nivolumab in combination with ipilimumab.

4. Urothelial Carcinoma: Patients with locally advanced or metastatic urothelial

carcinoma who are beginning pembrolizumab who:

1. Are not eligible for cisplatin-containing chemotherapy, and tumor is PD-L1 positive with CPS = 10, or are not eligible for any platinum-containing chemotherapy, OR

2. Have had disease progression during or following platinum-containing chemotherapy, or within 12 months of neoadjuvant or adjuvant treatment with platinum-containing chemotherapy.

5. Renal Cell Carcinoma:

1. Patients with advanced RCC who have received prior anti-angiogenic therapy, and are beginning nivolumab monotherapy, OR

2. Untreated patients with intermediate or poor risk RCC based on the IMDC score who are beginning nivolumab in combination with ipilimumab.

• Have at least 1 lesion that is measureable by RECIST 1.1
• Agree to a tumor biopsy 50 days after first GEN-009 vaccination
• Participants with hypothyroidism must be on thyroid replacement treatment

General Exclusion Criteria:

• Received a live vaccine = 28 days, or a non-live vaccine = 14 days, prior to the first dose of GEN-009
