Brief Summary:

This clinical phase II study is designed to investigate the efficacy of intratumorally administered L19IL2/L19TNF in patients with injectable lesions of BCC or cSCC. Favorable tumor responses following intralesional treatment with L19IL2/L19TNF have been observed in patients with injectable melanoma lesions of stage III or IV, for injected and non-injected lesions.

The proposed clinical phase II study plans to investigate the intralesional administration of 6.5 Mio IU of L19IL2 (~1.08 mg) and 200 µg of L19TNF to be administered in an approximate volume of 1.0 mL as a single or multiple intratumoral injections in patients with high-risk BCC or cSCC.

There is a high medical need for non-invasive therapeutic strategies with a comparable good response rate and high recurrence free survival for treatment of patients with BCC or cSCC, who cannot be treated by or refuse surgery. Surgery is not always applicable, as it may not be feasible due to the anatomic location, may have a poor cosmetic outcome for the patient or is generally not accepted as treatment strategy by the patient. However, current non-surgical treatment strategies have a considerably reduced response rate and recurrence free survival. Based on the favorable results for injected and non-injected lesions obtained in the phase II study of L19IL2/L19TNF and the good safety profile seen in the subsequent phase III study, both in stage III or IV melanoma patients, we believe, that patients with BCC or cSCC will profit from intralesional treatment with L19IL2/L19TNF.

Arm Intervention/treatment
Experimental: Single arm

40 patients will be enrolled and treated with a mixture of 6.5 Mio IU (~1.08 mg) L19IL2 and 200 µg L19TNF once weekly for 4 consecutive weeks. The dose will be distributed among the lesions via multiple intralesional injections.

New lesions occurring during the treatment phase will also be treated as described but the treatment period for new lesions will not be extended beyond the previously defined 4 weeks treatment period with clock-start at the time of the first intralesional L19IL2/L19TNF injection.

After the Tumor Assessment/Safety visit, patients may receive surgery in a curative intention within 6 weeks, in order to assess the pathological response with estimation of percent of residual viable tumor cells.

Drug: L19IL2 +L19TNF
Single or multiple intratumoral administration of a mixture of L19IL2 and L19TNF will be performed once weekly for up to 4 weeks into all injectable lesions present at the beginning of treatment or appearing during treatment phase The dose will be constituted by 6.5 Mio IU L19IL2 (~1.08 mg) and 200 µg L19TNF.
Other Name: bifikafusp alfa + onfekafusp alfa

Primary Outcome Measures :
  1. Efficacy of L19IL2/L19TNF in CR [ Time Frame: Tumor Assessment/Safety visit (Week 6, Day 36) ]
    Objective Response Rate (Complete Response CR) for each tumor type from beginning of treatment according to RECIST v1.1 criteria.

  2. Efficacy of L19IL2/L19TNF in PR [ Time Frame: Tumor Assessment/Safety visit (Week 6, Day 36) ]
    Objective Response Rate (Partial Response PR) for each tumor type from beginning of treatment according to RECIST v1.1 criteria.

Secondary Outcome Measures :
  1. Pathological Response [ Time Frame: At Surgery ]
    Efficacy of L19IL2/L19TNF measured as Pathological Response for each tumor type at the time of surgery.

  2. Safety (AE) [ Time Frame: Throughout study completion for each patient, an average of 12 weeks for each patient ]
    Safety of intratumoral administration of L19IL2/L19TNF, assessed by Common Toxicity Criteria (version 5.0, CTCAE)

  3. Safety: ECG [ Time Frame: Before first drug administration at Day 1 and at the Tumor Assessment Visit at Day 36 (Week 6). ]
    Electrocardiogram (ECG) findings. In particular, data about QT/QTc intervals will be collected and analysed for QT/QTc prolongation potentially caused by treatment

  4. Safety: change in vital signs [ Time Frame: Before first drug administration at Day 1, Day 8, Day 15, Day 22 and at the Tumor Assessment Visit at Day 36 (Week 6). ]
    Measurement of heart rate (beats per minute)

  5. Safety: change in vital signs [ Time Frame: Before first drug administration at Day 1, Day 8, Day 15, Day 22 and at the Tumor Assessment Visit at Day 36 (Week 6). ]
    Measurement of blood pressure (mmHg)

Ages Eligible for Study:   18 Years to 100 Years   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • High-risk, localized (non-metastatic, node negative, single or multifocal) BCC or cSCC amenable to intratumoral injection.
  • Patients with injectable and measurable regional cutaneous or subcutaneous in-transit or satellite metastasis but without regional nodal involvement are also eligible.
  • Male or female patients, age 18 - 100 years.
  • ECOG Performance Status/WHO Performance Status ≤ 1.
